Gas/Electric Hybrids, Air Cars in the News
hackshack writes "eCycle is developing a hybrid diesel / electric motorcycle designed to get 180 miles per gallon. The small diesel engine kicks in at speeds over 12mph, and the electric motor handles acceleration. Target retail price is $5,500. They've got a beta test program going as well. Now I can laugh at all those "gas-guzzling" Insight drivers as I zoom by!" Reader clen writes in about the Toyota Prius doing well in a road rally, and fishdan sent in a note about a pure-electric concept car called the Tango. And the air-powered car is getting a little more media attention, too.
Becuse there so fast I got FP on the topic. wh00t -5 karam here I come!
Drivers of the GM EV1 are trying to save the car, or at least stop GM from falsely claiming that nobody wants electric cars. See http://cleanup-gm.org.
I like how they talk about making a powertrain that's efficient at cruising speeds, when they've stuck the thing in a pure sportbike frame. They should have built a big honking Goldwing clone, or at least something like the BMW sport-touring bikes. Pocket rockets are not the place to worry about miles-per-gallon.
Thank you.
Somebody is holding out on us, and I don't like it (nor do I accept it - no car bought here yet).
why don't they use the self balancing technology of the Segway Transporter (see here) and with the (power?) they can generate with these (or hydrogen fusion?) and attach a jet/rocket pack to the bottom and use them as a fliey roundie thingy?
just a thought
air powered car sounds pretty sweet. I wish US consumers would latch on to it...maybe taxi services and urban services like mail trucks and meter maids?
wait...it doesn't hurt the enviroment...US consumers won't like it then.
This is what they mean by "air powered car"...
Finally, math books without any of that base 6 crap in them.
Cooper made the exit of that stream fifty feet wide, in the first place, for no particular reason; in the second place, he narrowed it to less than twenty to accommodate some Indians. He bends a "sapling" to form an arch over this narrow passage, and conceals six Indians in its foliage. They are "laying" for a settler's scow or ark which is coming up the stream on its way to the lake; it is being hauled against the stiff current by rope whose stationary end is anchored in the lake; its rate of progress cannot be more than a mile an hour. Cooper describes the ark, but pretty obscurely. In the matter of dimensions "it was little more than a modern canal boat." Let us guess, then, that it was about one hundred and forty feet long. It was of "greater breadth than common." Let us guess then that it was about sixteen feet wide. This leviathon had been prowling down bends which were but a third as long as itself, and scraping between banks where it only had two feet of space to spare on each side. We cannot too much admire this miracle. A low- roofed dwelling occupies "two-thirds of the ark's length" -- a dwelling ninety feet long and sixteen feet wide, let us say -- a kind of vestibule train. The dwelling has two rooms -- each forty- five feet long and sixteen feet wide, let us guess. One of them is the bedroom of the Hutter girls, Judith and Hetty; the other is the parlor in the daytime, at night it is papa's bedchamber. The ark is arriving at the stream's exit now, whose width has been reduced to less than twenty feet to accommodate the Indians -- say to eighteen. There is a foot to spare on each side of the boat. Did the Indians notice that there was going to be a tight squeeze there? Did they notice that they could make money by climbing down out of that arched sapling and just stepping aboard when the ark scraped by? No, other Indians would have noticed these things, but Cooper's Indian's never notice anything. Cooper thinks they are marvelous creatures for noticing, but he was almost always in error about his Indians. There was seldom a sane one among them.

Has anyone else thought about modifying a Prius/Insight/Civic Hybrid to get better performance and (more importantly) gas mileage out of it? I'm thinking of buying a Civic Hybrid (as opposed to a Prius, since I need a new car) in hopes of being able to use the already available civic mods.
Huge exhaust....sure
17" wheels......maybe
3 foot spoiler..definitely not.
How much energy does it take to charge up? This car will only be worthwhile if it takes less energy to charge it than would be consumed by a conventional auto in the form of gasoline over the same distance and hauling the same load.
I'm also a bit perplexed by the air exhaust filter. Why filter the outgoing air at all? If it's just expelling air that was pumped into it from the atmosphere, why would there be any reason to filter it? Surely the filtration decreases the efficiency of the car, since it would take energy to force the expelled air through the filter.

does that sound cool or what?
Archer: must...stop...driving...need air
Trip: here capt'n, try this tachyon modified gasoline. One deep gulp and you won't need all that extra air. Mmm, pecan pie.
It may be cleaner than gasoline powered cars - but is it safe?
Four tanks of compressed air at 4500psi contain a lot of potential energy. If they rupture in a car crash this energy will be released in an instant, spraying their surroundings with shrapnel. Sure, a tank full of gasoline isn't exactly benign, either, but outside of Hollywood cars generally do not explode in a fireball.
Stop worrying about the risks of nuclear power and start worrying about the risks of not using nuclear power.

please.. why couldn't the headline read "diesel /electric" hybrids, i was all worked up to see toyota prius converted for gas.
and in other news. this isn't really news.
world was created 5 seconds before this post as it is.
No. Read mine, you b14+ch3z. ;-)
Since electric /hybrid vehicles tend to be fairly quiet. I believe it is safe to say not many harly owners with find these hybrid bikes attractive, as it would be impossible for them to rev the motor in such a way sd to wake the dead whenever they arrived or left somewhere.
actually I am happy to see you, however that is in fact a banana in my pocket.
Keep in mind that Corbin Motors already has put solid, useful electrics on the roads. Can't say their vehicles would be very practical for everyone, but I've seen a few Corbin Sparrows in Boston and NYC, and it looks like they're the perfect urban-mobile.
I've had a Honda Civic Hybrid for about two months, 4,000 miles. I couldn't be more impressed.
It has enough pickup for the driving most people do. Its more comfortable than my Subaru Forrester, including more leg room. It handles well. Best of all, I average 50.8 miles to the gallon. Yes, there is a MPG gauge. It has a range of over 600 miles per tank of gas and is a Ultra Low Emmissions vehicle.
It charges its own batteries through regenerative breaking and cruising without depressing the gas pedel, e.g. going down hill. The electric engine kicks in for some extra horsepower when you drive uphill or are accelerating. The gas engine is only about 96 horsepower, but that is enought when you are driving a light car on level roads . I drive it through the Green Mountains and it performs very well. It can cruise at 70 mph or more on a highway very easily, though I find I downshift a little more in the Civic than my Forrester for some extra oumph.
I've added a Sirius Satellite radio, so now I can drive coast to coast on five tanks of gas while listening to the same radio station!!!!
Put your environmental money where your environmental mouth is and buy one! I believe congress has just pased a tax credit for people who buy a hybrid.
Go forth and be GREEN!!!!!!!!!!!!
Thank-freakin-god!!
Finally we get the technology that the new millenium deserves.
It has taken so long to get those flying cars!!!
Now for my three course meal in pill form...
Someone ought to tell him he won't be 'zooming' past any Insight/Prius drivers anytime soon, heh.
now if the diesel engine only kicks in over 12 mph, what happens in heavy traffic when the average speed is, in my experience, far less than this speed? Does the diesel turn on when the batteries reach a crucial lower limit? It seems like this would reduce the gains in fuel economy as with the diesel on you would just be running at the same economy level as any other diesel car. Further, you would also presumably be charging the batteries simultaneouly, meaning that emissions and fuel consumption will be greater yet (though still significantly less than a standard car).
Just a small concern, but it seems important to me as well.
"Hey brother Christian with your high and mighty errand / your actions speak so loud I can't hear a word you're saying"
Ok, everyhting looks pretty good in theory, and I'm sure it does well in application. I assume that with this, as well as most other hybrids, it is probably lacking somewhat in power. I checked the transmission specs, and it appears to be a 2 speed (unless I'm reading that wrong) and also appears to be an automatic. Maybe it's just personal preference and bias, but when I'm driving something that needs to get out of it's own way, I much prefer a stick to control the acceleration a little better (and eliminate the need for the automatic transmission to hesitate while it decides I want power).
Besides that, just for "asthetics", it should be a standard trans. I mean, I haven't driven a bike yet that's been an auto, and I'm sure that if they were that good, they'd be a little more prevalant in the market.
Ok, enough of my ranting. I would definately look into buying one though, if it was a stick.

And just how would you ensure safety of these air tanks? That's a HELL of a lot of pressure!
I used to scuba dive quite a bit, though I haven't for a few years now. For those of you who don't you may not be aware that there are quite a few laws/guidelines about air tanks and safety.
Each time you pressurize a dive tank you are doing two things: first, you're causing a huge amount of heat to build up and secondly, you're stressing the metal of the tank. The hotter the tank gets the more quickly the metal it's made of will become stressed over time and become unsafe. That's why scuba tanks are placed in water when they're being filled. A dive shop is required by law (at least around here) to render a tank unusable if they see ANY signs of damage or metal fatigue. It's just a fact of physics that a tank has only so many use cycles before the metal fatigue renders it unsafe.
The dive shop owner who trained me had an interesting story about an experience he'd had. Many years ago his shop purchased a number of surplus tanks from the military. They had certified that they were in good shape and safe to use. Being a cautious guy he decided to fill them up and use them himself before selling any to his customers. While he was filling one of them he noticed a slight odd sound. He thought it could be a leak, so he placed his hand near the gasket at the top of the tank to see if he could feel any air escaping. He didn't actually touch the tank.
The next thing he knew he was lying on his back in a different room. The tank had exploded, blowing him over 50 feet through two walls! All the interior walls in his shop were flattened, his ear drums were broken, he was bleeding from tears at the corners of his mouth and eyes, plus tons of other crap was damaged/destroyed. The tank was about 3/4 full when this happened.
This was a steel tank, which has a max pressure of 1500PSI. And these cars are at 4500PSI???
I dunno. I'd have to be VERY confident of the safety measures they use before I'd consider riding in one of these things.
The theory of relativity doesn't work right in Arkansas.
The problem I see with air-powered cars is the same as with electric cars -- it takes too long to refill 'em. That would be why nobody would buy electric cars. If it took three minutes instead of three hours, that'd be a different story. I know they said that you can go to stations that do this, but THEY have to cooperate as well (and shell over the hundred grand). Maybe they will. Who knows? Also, there were some questions that went unanswered: does it have AC, radio, etc.? Also, 120 miles isn't a good result for a benchmark. People will want at least double that. And how fast can it go uphill on a highway? I live in a reletively hilly area (that is, I live in a valley which is pretty much entirely on a slope). Anyway, back ot, gas/electric hybrids have been out for quite awhile. This is not news. Although it is a motorcycle, so I guess that qualifies...

about 90 percent of the world has no idea how much a gallon is. Hell, a UK gallon is probably even different from an US one. And UK at least made the decision to switch to the more civilized litre (yes, it's written litre.)
About 90 percent of the world has no idea how much a mile is. Hell, a UK mile is probably even different from an US one. And UK at least made the decision to switch to the more civilized kilometre (yes, it's written kilometre.)
Even more annoying : about 90 percent of the world doesn't count in distance, but in distance for volume.
Therefore 90 percent of the world doesn't understand your bullshit US centric measurements. I don't know, but if even the most tech savvy persons I am supposed to be meeting here can't make the switch to modern (as in post XVIIIth century modern) units, I fear America (read the US) will never see the light (hey, c is measured in "km/s", not in "weeks/length of the right foot of Henry VIII" !).
According to Michael Baltierra, a reporter for ABC News, "we tested the car and it ran quite well. The only major problem that we noticed," he continues, "was that it was quite noisy...
I knew there was a catch! I read the article thinking to myself: "How can the car pass wind like that without making the noise?". And the carbon filter is starting to make sense, too.

A Diesel smart car can do 68mpg(US) which is around 86mpg(UK) IIRC. Top speed of 86mph, group 2 insurance and a doddle to park.

They won't be officially released in the US till 2004, but there are importers already planning to ship them. The cars themselves have been around for a few years in Europe and they are all over the place. Daimler are planning a Diesel/electric hybrid version of the car.

I was all set to save up and buy an e-cycle (the original electric) YEARS ago. BTW this diesel hybrid is not news, it's been mentioned on their site for over a year now.
I wanted the electric one, even with 50mi range. They kept pushing dates back, then suddenly it's "Oh, we've decided to build this new hybrid bike instead, so it'll be a few more years."
I'm betting they'll stall for more investment money and then in another year or so go "Wait wait, we'll make a fuel cell bike instead! Just hang on another 3 years!"

In a car, changing gear and power delivery mid-corner isn't a problem, the car won't fall over or change line.
A bike, however needs completely predictable power delivery, if you change the power delivery on a bike mid-corner the line you're taking changes, you run wide or you fall into the corner. The rear tyre can also spin up. It's one of the reasons the new Honda VFR800 with VTEC is not doing so well (It's also as ugly as sin). The VTEC kicks in at around 7,000rpm and starts delivering more power.

Kevin,
I wish you would stop posting this crap and just move on with your life. I'm sorry that things worked out the way they did, but you gave us no choice. As it was, I spent a lot of time convincing Jon and Bill not to press charges against you for theft. I even managed to get you a week's severence.
Instead of being grateful that they gave you a break, you have become obsessed with trying to sabotage their business -- but your *BSD is dying posts are just silly. We move more product now than when you left. No one is calling and cancelling orders because of your anonymous messages on Slashdot.
I think that you could still have a bright future, but if this keeps up, Jon and Bill are going to get pissed off and have you brought up on criminal charges. Is that what you want? How many jobs will you get when potential employers see a criminal record that includes the theft of company computer equipment? Jon still has the laptop that he bought back from the pawn shop along with the company's original purchase records for it. He still has printouts of the ads you put up on ebay for the DLT auto-loader and the RAID array. There are records showing that your badge was used to gain entrance to the building at 2:13AM on the day that the equipment was stolen. On top of the thefts, we also have logs showing your attempts to break into the servers using your ID the evening after you were let go.
Do you want to end up being some guy's bitch in prison? That's what may happen if you keep this up. If you think that your shopping mall karate classes are going to do you any good there, you are in for a shock.

P.S. Please don't bother with denying this, who you are, and so forth. This started practically the day after you were let go.

I like how they talk about making a powertrain that's efficient at cruising speeds, when they've stuck the thing in a pure sportbike frame. They should have built a big honking Goldwing clone, or at least something like the BMW sport-touring bikes. Pocket rockets are not the place to worry about miles-per-gallon.
Did it ever occur to you that, in order to make this thing efficient, they had to be concerned with aerodynamics and weight? A Goldwing is neither light nor does it have a low aerodynamic drag (relative to sportbike designs).
You can't make a 40mpg semi by pulling an engine from a Geo Metro and slapping it into a Peterbilt.
That's nice - 180 MPG is roughly equivalent to 80 km/l to the imperial-challenged crowd. But check out the 100 km/l car done by Volkswagen(yes, that's 100 km to the litre, or 235 MPG if you don't like SI units). I'm not affiliated with Volkswagen or anything - it's just cool technology.

Fuel cells are for those who don't listen to crazy conspiracy theories.
-- 'The' Lord and Master Bitman On High, Master Of All
We need newer, more efficient technologies(fuel cells), not new vehicles that derive energy from the same old sources and technologies. Energy doens't come from nowhere and if we all had electric cars then there would just be more coal burning power plants. Just think of the hybrid Toyota Prius. Where do you think the electricity comes from? It's batteries. How does it charge these batteries? From the engine and energy collected from braking. The energy collected from braking is not a significant amount of energy to constitute any real sigh of relief to an oil shortage problem. Electricity isn't a free thing, even for a hybrid car. Try turning your headlights on and all electrical accessories next time you're in your car and listen to the engine. You'll probably notice that the engine loses some RPMs and then comes back up to speed. That's because your modern day computer controlled vehicle just started giving the engine more fuel/air to make more power to compensate for the power you're demanding from it's alternator. We need efficiency. We need fuel cells.
Why?
High pressure containers can be designed to fail safely. Simply put, the majority of the tank is stronger then it needs to be, then create intention weaker "seams". This encourages the tank to tear itself apart rather than disintegrating.
Why is tearing good? Because as the tank tears, the hole get bigger and the trapped gas can expand through a larger hole thereby decreasing the relative pressure. Combined with a kevlar webbing around the tank, and protection in the floor of the vehicle, these tanks are probably safer than petrol cars, simply because you can't burn to death.
For an illustration of this tearing effect, the easiest search is +fireworks + flowerpot. or look for failed oxygen cylinders.

Slashdot monitor for your Mozilla sidebar or Active Desktop.
And I don't give it a secoond thought. While I don't know what particular type of tank they're using here, I'd guess it's a carbon-fiber wrapped tank. They're actually pretty resilient - crushing damage isn't going to do much, as whatever pressure you manage to put on the side of the tank is going to be small compared to the 4500 PSI pushing back from the inside. Really the only likely way to fracture one is with some sort of piercing damage, and if that happens there's no shrapnel, the tank just kind of tears apart leaving you with a bunch of un-wound carbon fiber. You obviously wouldn't want this to happen right next to your ear, but other than that, as long as the passengers are separated from the tanks, safety shouldn't be an issue.

- how much of the appeal of a motor-bike is in the noise they make??
(And is this bike suitably noisy?
It's got the 'neato' factor, it'll be even cheaper to run than a 'conventional' bike...it goes
I'm not too thrilled about that white paint-job though
And I have to wonder...'e-cycle'
And then the biggest worry: What if the bike breaks-down? Who has the parts and the knowledge to fix it?
(Same with all those neato hybrid-cars...I can see big bills for the ppl who buy them (:\ Mechanics will be thrilled though...
(/worryhat)
Mind you, considering the amount of computers they cram into these gizmo cars/bikes, us geeks will not have to worry about future-employment either
While I'm at it...
I seem to remember that there are perhaps ((cough cough)) better 'intermediate' steps that could be used to move towards cleaner/more economic fuels, using the existing fuel-supply infrastructure.
i.e.
Dieselengines can run on a variety of (plant-extracted) oils without any/much modifications to the engine. These oils will (almost) burn clean, and because they're extracted from plants we'll never have to worry about running out. (Iraq? Kuwait? Where's that? Who cares!
The problem with plant-based oils was/is the smell. Even worse than a smelly old diesel truck.
as an example:
There was a research-project a while back where a guy on some pacific island managed to get diesel-engines running on coconut-oil.The exhaust-fumes smelled of...donuts (I think).

If voting were effective, it would be illegal by now.
And where do you think the hydrogen in those magical fuel cells of yours is going to come from?
That's right, water that is split into hydrogen and oxygen by electricity from those same power plants.
Fuel cells are not a new fuel source--they are an energy transmission medium.
Maybe when you can collect all that free hydrogen in outerspace and pipe it down to earth you might have a something.
I have no idea if you lot over in the USA have these, but here in the UK you can get government grants to convert your gasoline (petrol)-powered car to dual-fuel LPG (Liquified Petroleum Gas, a mixture of propane and butane, also called Autogas). Whilst this is, of course, still a fossil fuel, there are benefits in terms of emissions and fuel economy.
What ever happened to the German enclosed bike? I saw it once on Beyond2000 around 1995. It was 2 wheeled, but when you came to a stop, side-wheels came down on either side.
What's interesting is that Honda may have done a better job creating a real car using a hybrid drivetrain than what Toyota did with the Prius, according to Motor Trend magazine in a recent review.
:-)
The problem with the Prius is that while is quite roomy for its size and has good pep for the hybrid drivetrain, the road handling and the quirky ergonomics of the car may not be to everyone's tastes. Because the Honda Civic Hybrid is based upon the current model Civic four-door sedan, you get exactly the same interior arrangements as the current Civic (which is quite good), though the instrument panel is a little different (to reflect operation of the Integrated Motor Assist (IMA) hybrid drive system) and you do lose a little trunk space in order to accommodate the electric motor batteries.
I've driven the Civic Hybrid sedan with the CVT automatic and it's actually quite good, with decent acceleration thanks to the CVT transmission. If I had the money I'd trade in my Civic HX CVT coupe for the Civic Hybrid sedan with CVT automatic.
I think electric/fossil-fuel hybrids are the way to go for now until the arrival of low-cost, practical fuel-cell engines.
The Toyota Prius, Honda Insight and Honda Civic Hybrid have demonstrated you can get a very practical car with good driveability, very low emissions, and most importantly long range. Why get a car with 70-100 mile range (at best) when you can get something that can be used as a daily driver and also take a small family on long trips?
It's small wonder why both Toyota and Honda have begun to expand hybrid technology to their other model lines. Don't be surprised within a few years we'll be seeing small vans and station wagons with hybrid drivetrains from both Toyota and Honda; Toyota has stated they may produce a hybrid version of the Corolla and Honda is looking at putting hybrids into the Latitude (neé Stream) minivan and Jazz supermini hatchback.

Yeah right. Have you ever been around when a 4000 psi scuba tank explodes?
Most of the time there is no shrapnel because the tank just tears. BUT I've seen the tanks themselves go through 2 ft concrete walls, shoot across a street and lodge into the brick wall of a neighboring building about 150+ feet away.
Of course those tanks are metal, but I would hardly declare those tanks as safe especially since they are much more likely to be ruptured in an accident. Scuba tanks don't really have to suffer much abuse compared to to a 3000 lb vehicle smashing them.
How much could they extend the battery life by putting photovoltaic panels on top of the air powered vehicles?
i'm personally waiting for next year's escape offering from ford.
it's an HEV and looks like it shares alot of the characteristics/fuel-saving properties of the ULEV honda civic. (hybrid, regenerative braking, etc)
it's only about 40 mpg, but that's still pretty impressive for an SUV when other big cars have ridiculous mileage (ie: escalade : 11 mpg).
i drove an escape for an entire summer once while i had a summer internship and they paid for it (sigh...those were the days), and that car is damned fun.

I'm gonna laugh at your ass after your cycle folds when it runs into a signpost
So yea. Did I miss something or did this company make a 0 emission car and fail to explain how that will reduce emissions? If suddenly we have to use the SAME if not more amount of energy in electricity for charging the car then we are burning more coal and taxing the electirc usage of our world. What we need is not a conversion of power, but a method that has low or no emissions and is also efficient, which this article just doesn't even mention...
The so-called "Big Dirty" power grid is far more efficient and polutes less than any small motor does. Even in a ultra super clean vehical like the Prius (which I own) you get much higher levels of polution for the amount of energy you produce from the fuel you directly use than the least clean coal burning plants. Using compressed natural gas in a more conventional engine really wouldn't make a difference in this regard. And frankly there are many natural gas fired electrical plants already.
The simple fact of the matter is that large power plants are 60-80% efficient at extracting the energy out of fuels, while the power plant in a vehical is 5-10% efficient. In fact, most of the fuel economy in electric and hybrid cars comes from the regenerative braking system taking the energy that is lost in a conventional car and storing it for when you accelerate again.
Of course, once we get fuel cells that actually work then that won't be true anymore, because the catalytic buring of the fuel inside a fuel cell is at 90-95% efficiency.
At that point compressed natural gas would be a great choice.
eCycle's has an "acceleration of 0-60 mph in 6 seconds." Bah. When you're on a crotch rocket and you absolutely, positively gots to go 0-60 mph in 2 seconds or less, accept no substitutes. [Ducati.com]
Of course, a Ducati, is a bit more pricey and more of a natural resource hog, but nothing beats accelerating until your brains splatter on the pavement.
Recently we had to do an estimation problem in our physics class. The question was how much gas would the US save each year if every SUV driver drove a hybrid instead. My group came up with a savings of almost 14 billion gallons of gas per year. (20m SUVs -> Hybrids, 15mpg/suv, 45mpg/hybrid, 15k mi/year) Which is apparently almost exactly the amount of oil our country imports every year. I'm patriotic and all, but I'm really tired of seeing the American flag on EVERYTHING, EVERYWHERE I go. If our fellow Americans truly wanted to be patriotic and hit the middle east where it hurts, we'd trade in our gas guzzling SUVs and eliminate the need for imported oil.
Those little planes run on compressed gas turning a piston. It sure seems like a good proof of concept to me. But, on the other hand, those planes aren't that heavy and they sure don't fly very far. Certainly not 150 miles. I wonder if they can really pack that much energy in a small place, even if it's only air.
I am happy to see other companies get into the "alternitve" powered vehicles for a few different reasons. The first being, that they have few, if any, ties to the oil companies, which LOVE to inhibit any move away from petroleum. A few comments I have on hybrids...
I am EXTREMELY happy to see a diesel hybrid. For some reason, every big car company has shied away from diesel in place of the petrol engines they use. Diesel engines are more efficient and CAN be clean. The reason US diesel engines are dirty is because the refineries REFUSE to add one more step in removing the sulfur from the fuel. They do this in europe, which leads to a MASSIVE assortment of diesel engines varying in size and power. I tend to think, they could make a diesel hyrid that could easily get 80mpg in a car and still have decent power. If they could get an efficient CVT with a turbo-diesel hybrid, they could take over the hybrid market in every country. But, I wont expect that any time soon.
Oh come on already, I have a NORMAL honda motorcycle and I get ~ 100 mpg out of GASOLINE without having to fuck with electric motors and messy diesel. I also can go a FUCK lot faster than 12 mph!
You seem to be laboring under some illusions, and you are taking for granted quite a bit of analysis.
First of all, your statement that "Energy doens't come from nowhere and if we all had electric cars then there would just be more coal burning power plants," applies equally well to fuel-cell cars.
The fuel in a fuel-cell has chemical potential energy, which is converted into electrical potential energy, and then kinetic potential energy. But to create the fuel requires putting energy in up front. There are a lot of candidate fuels for fuel cell technology, but the bottom line is that you either need to make fuel by putting energy in, or convert an existing fuel into a useable form. In the former case, you need to put fuel in to the system, in the latter you are using fuel. I know that in theory, you could use solar to directly liberate hydrogen or something, but for now that is not going to happen. And in any event, that same technology could be used to replace coal plants, too, which nullifies your complaint about pure electric cars.
Then you seem to imply that there is no energy efficiency gain from compressed air cars. I am somewhat willing to believe this, but do you have some kind of argument which supports this implicit claim?
Something that you are overlooking is economy of scale in large power plants. While it is true that if we were all driving electric cars, we would need a beefed-up electric grid, it is also true that big electric plants are more efficient than cars in extracting energy, and that they are also easier to regulate and monitor.
Also, one of the reasons that hybrid electric vehicles get good overall mileage is that the motor is optimized for a narrow load range, unlike conventional automobile motors which have to supply reasonable torque over a wide RPM range. This means that the hybrid power plants can be more efficient and/or simpler.
Finally, I have never seen a detailed energy analysis of the fuel-cell energy cycle. If you postulate wide-scale adoption of this technology, does it actually lead to reduced consumption of fossil fuels or not? I am willing to believe that it does, but I am not swayed by your unsupported assertion.

Well.. where are the fuel cells? Did the oil monopolies win already?
I think the magic Google word you're looking for here is Biodiesel.
The problem is, of course, that the nation uses lots of frying grease, but nowhere near enough to replace Gasoline.
I believe there's a rather extensive intro article on Biodiesel in Home Power(Apologies for PDF - They're lame, but what do you do?), which should answer most of the questions you never had about the subject.
It's an interesting idea, but there are several problems with the overall design. For one, it looks like the seating position is fairly agressive, like a sportbike, so you probably aren't going to want to go 180 miles or more on this thing. The seat itself looks tiny and uncomfortable. For another, 0-60 in 6 seconds on a motorcycle is pretty slow, especially one that looks like it's supposed to be a sport bike. Lasty, I speculate that such a small (~250 cc) direct injection diesel combined with an electric motor is going to have serious surging issues, which are no fun (ride an "unfixed" BMW F650GS and you'll see what I mean). Direct injection diesel might not do too well here in the states either due to a slightly different formulation. And really, motorcycles are already pretty fuel efficient. If you really want to do some good IMHO, develop fuel efficient SUVs, pickups, 18 wheelers, buses, and marine engines.
So: 0 to 60 in 6 seconds. Well, yes, my little Italian 125cc racer could manage that years ago. It weighed about the same. It also put out about 25hp., was a pig to keep on the boil, and used quite a lot of gas. A quick back of envelope calculation suggests that the electric hybrid would need a combined output (elec + diesel) of around 20 hp to get the same result. There doesn't seem to be enough power there.
Nor, in fact, does there seem to be enough power to maintain a sustained 80mph. That little 200cc Diesel can't do it, and the batteries run down when using the electric motor as well.
Ah well, let's just wait for the fuel cell to fulfil the promise it's been showing for the last 50 years or so...
Panurge has posted for the last time. Thanks for the positive moderations.
I said we need newer technologies. "more efficient technologies(fuel cells)"
"First of all, your statement that "Energy doens't come from nowhere and if we all had electric cars then there would just be more coal burning power plants," applies equally well to fuel-cell cars."
Of course it does, that's why I said we need new technologies. I never said fuel cells produce energy from nothingness.
"And in any event, that same technology could be used to replace coal plants, too, which nullifies your complaint about pure electric cars."
America uses way too much coal power. Which do you think will take the energy producing market first? Fuel cell vehicles or fuel cell power plants?
"Something that you are overlooking is economy of scale in large power plants. While it is true that if we were all driving electric cars, we would need a beefed-up electric grid, it is also true that big electric plants are more efficient than cars in extracting energy, and that they are also easier to regulate and monitor."
Valid point but we still use too much coal for power plants.
"Also, one of the reasons that hybrid electric vehicles get good overall mileage is that the motor is optimized for a narrow load range, unlike conventional automobile motors which have to supply reasonable torque over a wide RPM range. This means that the hybrid power plants can be more efficient and/or simpler."
This can be done with any motor. But... everyone in American wants to drive a Ford Excursion.
"Finally, I have never seen a detailed energy analysis of the fuel-cell energy cycle."
Fuel cells have energy efficiency ratings of around 50% whereas internal combustion engines running on gasoline have about a 25% efficiency.
No, not a gas generator. Those things have horrible efficiency, and no emissions controls whatsoever. What about a fuel cell though? Install one in the trunk, duct the air intake from under the chassis, duct the steam output to a "tailpipe", and leave that sucker on all the time to trickle-charge the batteries, in conjunction with an external charger. Make sure to get rid of the inverter, so you can bypass all that charging inefficiency to feed DC directly to the battery pack. Of course, this increases the high cost of your electric by another 10K or so...
Sigh. Maybe sticking a patch of solar cells on your roof would work better.
From the Tango article:
UPDATE 9/5/01: Our U.S. utility patent case for an "Ultra-Narrow Automobile Stabilized With Ballast" has just been allowed. International patent applications are in progress
Reminds me of Weeble Wobbles. "They weeble and they wobble but they don't fall down!"
So if it gets hit by a truck and goes flying for fifty feet, will it land right-side up?

Please note that motorcycles already deliver fuel efficiency far more superior to fuel efficiency of cars.
For example, Harley-Davidson's Blast 492cc motorcycle gets 69mpg (city) and 73mpg (highway) and retails for $4,395. (source)
And that's the first bike I could find details on. There are bikes that are better.

His design heats the air to ambient temperature. You can get more work if the air is heated to a higher temperature. For example, heating it to 600 K will roughly double the work for a given quantity of air.
You could burn a fuel (external combustion engine), or you could use a 'thermal battery', which stores heat in a high temperature material in a vacuum insulated container. One can readily exceed 1 MJ/kg; this is much higher than the storage density of lead-acid batteries.
You can also get the TDI in the New Beetle. The neat thing about the TDI VWs is that while the horsepower is only around 90-something, the torque is around 150 or 155. That'll make for some nice acceleration, which many people appreciate.
Cough cough... second law of thermodynamics... cough cough... an MIT enterprise... ROFLMAO!
I'd love to have one of those motorcycles, but it looks like crap. I don't know why the people designing hybrid vehicles insist on making them look like shit ... don't they get it? Build a hybrid vehicle that looks NORMAL, and people will buy it.

I own a 1992 Honda Civic VX. During the summer months I have been getting between 50 to 55 mpg. (Winter it will drop to 45-50 mpg.) My car is 10 years old. Why is it that Honda's best mpg car is just as good as my 10 year old car?
In 1992 it had the second best gas mileage rating (52 mpg on the highway) of all the cars. Geo Metro which was a much smaller car had better mpg. The only difference between my Honda Civic VX and the other Honda Civics was the engine. Why is it they can not do better?
Correct. I have a Mercedes C200 that was converted to LPG. Got no grant, but hey.
;-)
/just/ going to be approaching the economy of a regular American car. :-(
It works out about 6.9p (about 10.5 cents) per mile in the Merc now on LPG.. whereas my Corsa 1.2l works out at about 9.6p (about 15 cents) per mile.. so I can drive a 2 litre Merc for cheaper than a 1.2l Corsa
Of course, the fact that fuel is three to four times more expensive in Europe means that even a 100mpg car is only

There already is an alternative to the Honda Civic, but they don't bring it into North America (I wonder why??) The Volkswagen Lupo:n /45kwtd i.htm
http://www.volkswagen.de/lupo/daten/motore
It also has a top speed of 170km/h (100mph +). It has a 3-Cylinder Diesel TDI motor. The fuel economy is outrageous with a combined (city/highway) usage of 3.0 - 3.2 L/100km or 94mpg (Can.)
I run a truck on propane LPG fuel it was converted from gasoline.
In some states like NM you save a lot of money since propane relatively easy to find and it is a little cheaper than gas.
But is California it all depends where you live, around San Francisco propane is very hard to find, it is usually very expensive, sometimes up to $3 a gallon, which makes it a lot more expensive than gasoline, in best case it is equal.
The exeption seems to be Los Angeles, where I have seen propane for as little as $1.10 a galon.
Another problem with propane in California, is that emission laws do not make any sence, it does not matter if your vehicle burns really clean if it does not meet other requirements, like a visual inspection.
Due to that visual inspection a propane vehicle is a huge headache to register is california.
In reality you have to go to the referee station, any other station will not do the emission check if you run on propane, the referee will ask you for some legal documents that prove that the equipment is legal in the state of california with the governor approval, usally the maker of the propany kits keep track of this, but the legaly depends on the year of the vehicle and the type of kit, in other words a vehicle that is perfecly legal in NM may not be legal in california.
When I needed work to the done on my vehicle to route some vacum hoses to comply to California law, no shop would due that for liability reasons and the lack of knowledge of propane, the nerest place was in L.A. and in Sacramento, so I got a manual and routed the houses according to the law.
It all worked out fine, it passed the visual inspection and the exaust check, but it took an entire month of paperwork, and getting the needed info.
So for all practical purposes a propany vehicle is ilegal in California, unless you are willing to go through massive paperwork in order to get it registered which in some cases it is not posible, I got lucky the kit I had fitted in the year range acceptable by DMV.
So basically propane is highly discourage in California, nevertheless here they always talk about passing laws for clean air. What a contradiction!!!!
In NM the registration for a propane vehicle is very simple it is just treated equal to a gasoline vehicle, and you can modify anything as long as it burns clean.
I do not know about other states.
I now use the truck mostly in Mexico, and the saving here is huge, propane is half the price, and there are a lot of places that work on propane vehicles.
Note, I never got any tax break in USA for the propane convertion.
It is interesting to hear about LPG use in the States.
You seem to have lower fuel costs locally, but I have to wonder if it's really worth the conversion price in the US. In Europe, things are different.
Gasoline is about 75p ($1.12) per *litre* (about 3.9 litres to the US gallon).. so about $4.39 per gallon to you.
LPG, on the other hand, is about 35p (51 cents) pet litre, about $1.98 per gallon to you. However, if you do a lot of travelling around Europe, you can get LPG as low as 19p per litre ($1.11 per US gal) in Belgium, for example.
Compare $1.11 with $4.39, and you can see why LPG should be popular here. In the US, it sounds as if there is little reason to switch, other than for environmental ideals.

Tucker didn't crush his 50 "beta-test" cars, and now each one is this priceless collectors item. Chrysler crushed all the Chrysler Turbine cars, supposedly for tax reasons but the real reason was not providing a windfall for lucky collectors. GM has done the same thing. Don't you think those EV-1's would become incredible trophies for collectors?
Check out the VW Lupo TDi .
The mileage is "3 Litern auf 100 km", and this translates to, roughly, +78mpg.
Remember:
1US Galon = 3.789 L
1 mile = 1.609 Km
And you can buy it today... if you live in Europe.
Why doesn't #2 Diesel cost 10 percent more than gasoline. Well, actually it does, or it would. During the winter, gasoline is about 10 cents a gal cheaper than 87-octane nolead, but in the summer, with everyone sucking up gas in the RV's and SUV's, and refining capacity fixed by a conspiracy of refiners and environmentalists (heck, I wouldn't want a refinary next door either, and limiting capacity boosts prices and serves industry interests as well), there is a 20 cent premium for gas over Diesel.
Home centers are designed for the do-it-yourselfer who's willing to ...
pay higher prices for the convenience of being able to shop for lumber,
hardware, and toasters all in one location. Notice I say "shop for," as
opposed to "obtain." This is the major drawback of home centers: they are
always out of everything except artificial Christmas trees. The home center
employees have no time to reorder merchandise because they are too busy
applying little price stickers to every object -- every board, washer, nail
and screw -- in the entire store
Let's say a piece in your toilet tank breaks, so you remove the
broken part, take it to the home center, and ask an employee if he has a
replacement. The employee, who has never is his life even seen the inside
of a toilet tank, will peer at the broken part in very much the same way
that a member of a primitive Amazon jungle tribe would look at an electronic
calculator, and then say, "We're expecting a shipment of these sometime
around the middle of next week."
