      Yeah, I really don't like the interface in the prototype. Fortunately, it's skinnable also. So you can have a car with pedals. Part of the review says that it'll be a better car without pedals because the steering wheel will have a better range of motion. However, if you are handicapped and missing legs or something this would provide a great deal of independence I'd think.

      I was pretty impressed with the performance specs. 97+ MPH out of 130ish horespower is not bad. When they can pull 200 HP out of it and have 4 wheel drive (more for safe delivery of power than offroad, think Audi Quattro not Land Rover) and you'll have something I'll want to buy. Oh, and 250-300 mile range would be good also.

      Begs the question of "how do you measure fuel economy". MPG (or L/100Km) is a bit off, unless you measure the capacity at STP. I think we need to go to a straightforward percentage (how many joules were liberated and how much forward momentum/sec was generated).

      Uh, yeah it is. Honda's been making cars that'll do 120mph with less than 90hp for decades. 97mph is a joke. Then again, I've never fully understood why cars in the US can go 120mph which is double the old national speed limit.

      Because infernal combustion engines and their associated machinery like gearboxes aren't efficient when run near the upper or lower limits of their capability, but in the middle. Upper is defined here as maximum rpm, not torque (which occurs closer to the middle rpm), and lower is the idle rpm. Car gearboxes aren't like aero engines; there is a direct relationship between engine rpm and wheel rpm via the gearbox.

      If you want a car that runs well at 60mph, you have to built one that peaks at 120.

And it's a constant torque curve, so it'll accelerate like crazy (which is really the reason I want the 4WD). Internal combustion engines generate torque (and HP) as their RPM's increase. Fuel cells use electric motors, which have the same torque at 10 RPM as they do at 10,000 RPM.

      To turn your argument around, I've got a 1 HP engine in a radio controlled car, and it'll do 60. Some others will do 85 with not much more power. So Honda's not living up to that standard! How dare they produce inefficient cars that take 90 HP to get to 120 MPH.

      "Internal combustion engines generate torque (and HP) as their RPM's increase"

      Well that's all up to the transmission, displacement, and a few other factors. Most cars generate peak torque low in the rpm range and higher horsepower as the rpms increase. Nearly every VTEC equipped Honda will generate peak torque around 3000-3500 rpms, while the peak hp comes at redline in each gear. On the other hand, your garden variety Subaru Impreza WRX generates peak torque at a low low 2200rpm, and peak hp near 6000rpm.

      At any rate, comparing rc cars to full sized vehicles is just a ruse. Thanks for the insight.

      While I'm pretty sure you're kidding there are a few reasons to do this onthe HyWire car specifically.

      First, the controls are really different, twist = acceleration, squeeze = brake. Not terribly different from motorcycle controls when you think about it.

      Second, this is probably not going ot turn into a production vehicle. It is sort of a meta-concept car. The fuel cell stuff is all squished into an eleven inch slab centered roughly at the wheel axes. Basically, less the controls, the everything useful but the passengers fits into this tiny space. Next they bolt a bunch of random stuff onto the top. It allows them to design a bunch of body plans without having to remake or remount the engine every time they come up with a new body concept.

      The weird controls probably evolved out of this in a way, they wanted a interface module that could be removed easily. Pedals, because of their location relative to the slab thingy would require a commitment on their part as to where a lot of stuff would go. This way they can play around with configuration to their hearts content.

      Not entirely unlike a 'skinnable' car when you think about it. I think it would be kinda neat to see in a production car, modular form like this. You go in, choose a chasis power rating or something, then choose a bunch of options (two, three, four, or six seats, truck bed, trunk, seats that recline all the way back, sporty aerodynamics, maximum cargo space, driver seat with a high field of view etc). Then you leave for a few hours while they bolt the thing together. Okay, maybe not, but, it's an interesting concept. Imagine, instead of renting a truck for the weekend to move, you go down to the dealership and rent a truck bed, they hold onto your rear seats until you come back.

      As far as the completely transparent front design, I imagine that takes some getting used to, what with the road being that much more obvious as it streams past you.

    Hydrogen hybrid cars are all well and nice, but they don't get us anywhere. At the moment the only ways to produce hydrogen are expensive and inefficient, and end up costing more "regular" energy (usually provided by fossil fuels or nuclear power) to produce. Electrolysis is good to play with in the physics labs at school, but when it comes to produce very large quantities of Hydrogen for mass consumption it's worth practically zero.

    I read a while ago in New Scientist that some group in Japan was trying to use a solar-pumped laser in a satellite to convert large quantities of salt water (in a big tank on an island) with an added catalyst, into hydrogen. That's the sort of news which are worth noting when it comes to cleaner fuels. Once hydrogen is available in every gas station, oil will die off naturally. Until hydrogen can be produced cheaply and in very large quantities, there's not going to be hydrogen in gas stations, and all these hybrid efforts are just lip service to make Sunday Ecologists feel better about themselves, so presenting this sort of news as a notable even in the move towards cleaner fuels is like saying "Microsoft issues a new patch for IIS, saves the internet from script kiddies".

    - You can't really 'skin' it. Yes, the shells are interchangeable, but at the factory. A home user bolting on one of these in his/her garage is opening up all sorts of safety concerns.
    - Yeah, it's Hydrogen, but it's not gonna blow up. Certainly not as dangerous as the tank of gas in your car. Go read the Wired article if you want details. It's not a rolling Hindenberg.
    - The wheels can pivot in any direction, which is why the steering is different. No more parallel-parking mishaps, hopefully.
    - They are still more expensive than regular cars, price- and energy-wise, but the trend is looking quite hopeful.
    - The space-savings inside the car itself are remarkable, and allow for all sorts of kooky things, such as a floor-to-ceiling windshield. (how weird would that be on the highway?)
    - The HyWire is a concept. They won't all be 'ugly'. The whole thing is still a good 10 years away.

    GM has gone on the record saying that, because of the elimination of most of the moving parts, these cars could realistically last 20 years. Which is a big concern for GM, obviously having a 20-year-turnover on cars is going to nail their bottom line... until you figure in the savings on engine parts, assembly lines for those engine parts, etc. Suddenly the AUTONOMY is a lot more attractive, as they might eventually cost a fraction of what regular cars do. GM recoups the lost turnover sales from the other 80% of the planet who can now afford a vehicle. And we get cool pivoting space-cars that cost $5000 and go for 2 decades.

The question is where does it come from. The 3 most common ways are compressed gas as was used in the article, gasoline, and methanol. Methanol and Gasoline both require a reformer to break the hydrocarbon chain an mahe H. Gasoline is a complex hydrocarbon, has an excelent energy density, but is complicated to reform than methanol. It is also supported by a large infrastructure. Methanol is a simple hydrocarbon that is easily reformed into H. It has approximately .5x the energy density of gasoline. One very large benefit is that it can be generated from local renewable resources. Anyway the H is made, there will be side efects. Reforming does produce carbon as waste. It can be captured as a liquid or solid rather than a greenhouse emission. Methanol from plant byproducts has all of the nasty issues of industrial farming.

  14. Why Hydrogen is Interesting by starseeker · · Score: 5, Insightful

    For those of us who haven't figured this out yet.

    Obviously, hydrogen is not an energy source when used in a fuel cell. That is not its purpose. Its purpose is to be a replacement for gasoline. Gasoline is not an energy source in the same way hydrogen isn't. Gasoline is millions of years of stored solar energy.

    It took millions of years to create the raw materials we use to make gasoline. Once we run out (and we will run out - we are taking it out faster than nature puts it back - it's just a question of when) we will have to either make more gas ourselves or split water to make hydrogen. There's no special difficulty hydrogen presents in this regard - anything we use to run cars is going to be in the end an energy storage device, unless we have nuclear/solar powered cars. Both are impractical, for different reasons. So we have two problems in the future - generate power to replace the huge stored supplys we current are tapping, and store it for use in automobiles.

    People seem to assume hydrogen is being proposed as a power generator. FALSE. Hydrogen is being proposed as a way to store energy for use in cars, which can't generate power on site in most cases. Gas is stored power - so is hydrogen when used in a fuel cell. We can't practically create gasoline ourselves - it's much easier to split water and recover the hydrogen. Plus fuel cells are extremely clean and don't give us the byproducts gasoline does. An extra benefit.

    That leaves the question of where to get the power to drive this system. That's a completely separate problem, and one of the most crucial. Solar and wind are the two major untapped as far as non-nuclear power goes. Nuclear isn't practical in the us IN ITS CURRENT FORM. Fusion power is under development, and if a power producing fusion plant can ever be created, that will provide lots of power with byproducts that decay in hundreds of years, not tens of thousands. That may be managable. Otherwise, we will have to adjust ourselves to run on only what power we can recover from solar and wind.

    It's never popular to say it politically, but we can in fact do a great deal to lower our power consumption. Better consumer habits, more efficient homes and utilities, smaller cars, etc. etc. etc. If we can't solve fusion, the cost of power will force this change to take place. It's not an argument of "we shouldn't develop renewables and hydrogen because they can't deliever our current level of power." Sorry folks, it doesn't work like that. Our current level of power generation is unsustainable unless we shift almost totally to nuclear power. Peroid. We don't know exactly how long it will last, but it WILL come to an end. What is up to us is how we cope with it. I'd rather be prepared with the best we can do in alternatives. Hydrogen might allow us to run cars after we can no longer produce gasoline cheaply. Plus it's a cleaner system when the source power is produced from clean sources. It doesn't provide gluttonous power, true, but it might allow us to sustain the worthwhile parts of our lifestyle. That's why this is a development to be cheered on.
