Looking To Better Engines Instead of Electric Vehicles
hlovy writes "Don Runkle thinks it's engines, not batteries, that will make automobiles cleaner and more efficient. 'We unabashedly say that we have the best solution,' says Runkle, the CEO of Allen Park, MI-based engine developer EcoMotors International. The startup, which brought in $23 million in Series B financing this summer from Menlo Park, CA-based Khosla Ventures and Seattle billionaire Bill Gates, has designed an opposing piston, opposing cylinder engine that uses fewer parts than traditional motors do and generates more power from each stroke of the engine, CEO Runkle says. He says the 'opoc' engine is smaller, lighter, and less expensive than the motors already out there, and a more viable option than switching automobile fleets over to electrical power."
When you can store energy as densely as liquid hydrocarbon, you'll have a successful electric car.
I want to delete my account but Slashdot doesn't allow it.
An engine-developer and seller tells us that the future is in the engines that he happens to be able to sell you. Didn't see that one coming.
Now if someone would just rear-mount that in a cute little chassis, maybe one that looked kind of like a bug or something...
Oh, yeah, it's not easy to pad these out to 120 characters.
I see a lot of buzzwords, but the few words with some real content in it makes it seem like this is just a two-stroke boxer engine.
More efficient? No shit Sherlock, that's always been the province of the two-stroke. The problem was how to keep the lubricants out of the combustion chamber so that it wouldn't be so damn polluting.

"I know I will be modded down for this": where's the option '-1, Asking for it'?
Just because some of the world's power is generated by coal, doesn't mean it all is. There are plenty of places where renewable sources make up a significant if not a majority of the power on the grid.
I don't know the limit of efficiency that this new engine design will deliver, but at any sane value this does not solve our biggest problem here in the United States (and probably other nations as well.)
Everything we do is regulated by oil. Our food distribution runs on diesel, our manufacturing runs on diesel. Our military runs on diesel. Our workforce requires gas to get to work. Every facet of American life is dependent on oil based fuels without which our economy, our military, our industry, our agriculture and our commerce will fail. Even with extreme improvement in our ability to harness these fuels, it is extraordinarily unlikely that we can produce enough fuel to be self-sufficient. In short our national security and our very survival are in the hands of foreign powers.
In the best of circumstances this would be worrying, depending on close allies for your ability to survive is harrowing, but sustainable. We are not in the best of circumstances, The nations that produce the majority of oil are not staunch allies, but nations with populaces that are predominantly anti-US. At any time the structure in these countries could break down and we could find ourselves at war with them. This would be a war that even if we win could destroy us as a nation. If we conserve all our fuel resources for the War effort, which we would have to do if we want to win with conventional weapons, we would find ourselves bereft of fuel and the fuel production infrastructure itself most likely in shambles due to the war. Our way of life would be over just as surely as if we had been conquered by a foreign power.
We need to switch to electric not because it is more efficient (although it is) not because it will create jobs (though it will) not because it can be more environmentally sound (although it could be); we need to switch to electrical power because it keeps our vital infrastructure requirements in our own hands. It is a matter of national security, no nation can prosper if it id dependent on unfriendly nations for its very survival.

"On a grander scale, Runkle says the EcoMotors technology is ultimately cleaner than plug-in electric automobiles, because it produces more efficient power without having to tap grid electricity—much of which comes from burning coal."
Again, burning fuel is always going to be the less than ideal solution, no matter what the power is used for.
Clean, renewable energy is the way of the future.

for sufficiently cheap power you can compromise on density.
Comments so far seem to ignore the issue of mass/power: every kilogram of mass you tack onto a vehicle, reduces its performance. Because that weight has to be accelerated, and at the next stop sign that weight has to brought to a halt. And for most vehicles, "brought to a halt" means wasting the energy that was stored in the form of kinetic energy (vehicle's speed). An electrical vehicle may re-capture some of that kinetic energy, but never 100%. And if a re-capture system adds another 10 kg. to vehicle weight, that's another 10 kg. that rides along, that needs to be accelerated & stopped.
So everything has both a + and - effect on overall efficiency, and driving style / area where a vehicle is used also counts. Cheap power doesn't gain you anything if using it reduces overall efficiency to the point where you started from.
Anyone who claims that electric vehicles generate zero pollution is misinformed. However:
1. Electricity doesn't only come from coal. In some places, electricity primarily comes from coal, but in other places, it primarily comes from hydro-electricity or other sources. So, the environmental impact of electric vehicles depends on where the electricity comes from, and it's by no means as simple as saying "all electric vehicles effectively burn coal".
2. By concentrating the polluting aspects of energy-production, it is easier to control. Getting millions of cars to upgrade (or even just maintain) their catalytic converters is a non-starter. Upgrading (or properly maintaining) the scrubbers on a single power plant is more feasible. As new technology enables greener power plants, the entire fleet of electric vehicles benefit.
3. Even if electric vehicles currently rely (partially) on CO2-releasing energy sources (e.g. coal), the long-term possibility is to migrate to other kinds of electricity production. Relying on burning fossil-burns locks one into CO2-releasing infrastructure. However, electric cars immediately 'benefit' from switchovers in the energy grid, as, for instance, more solar-panel and wind-farm sources are added to the grid. Using electricity for intermediate energy storage/transmission, allows us to gradually rebuild our infrastructure to be greener, which softens the switching costs.
4. For fair comparisons, one must also include every part of the chain in both cases. For instance it is true that electric vehicles require extensive mining and manufacturing, and incur transmission losses... but of course the use of fossil fuels requires extensive drilling operations (with associated spills, etc.), refining, and requires transportation (pipelines/tankers/gas-trucks). Each of these steps have variable levels of environmental impact. The intention is of course to have the chain with the lowest impact possible. The two chains are not identical in terms of environmental impact.
Yes, there are tradeoffs, such as transmission losses and the environmental impact of mining materials for batteries. But the idea of investing in electric vehicles now, even though they are not perfect, is to migrate towards an infrastructure where our vehicles have a lesser environmental impact. The end state, where instead of having millions of separate combustion engines, we create power using higher-efficiency power plants (including many that do not generate CO2: nuclear, solar, wind, etc.), is a net gain (even taking into account the impact of transmission losses, mining, etc.).
Your futurology, like your sig. Does not make sense.
Once you have a suitable storage system (battery) there is no point having the extra complexity and weight of a mechanical engine in the car.
It's down to the batteries. If they become small and light enough to give good range on a car, we will go full electric over the following decades. The economies of scale for fixed electric generation will ensure this.

hybrid is too expensive now for most uses unless you have a lead foot or you live in your car and drive 50,000 miles a year. my new 2010 CR-V has a real time miles per gallon calculator on the dashboard and i can easily go above 30mpg at 65mph and at 30mph. speed is not that big a deal in mpg ratings. the only time it drops a lot is when i accelerate which is a lot since i'm in NYC and we have a lot of traffic lights.
a lot of the SUV's have hybrid versions because most SUV's are modern versions of muscle cars. they are close to 300hp but with luxury and people buy them for the power of hitting the gas and taking off. the hybrid part helps if city driving with constant stop and go since you can get good acceleration with the engine turned off
Sounds like numbers from the 1982 VW Rabbit...

Everyone makes that same sorry mistake, extrapolating an unfavorable curve to infinity as if problems don't have gradual solutions. Lost of Bruce Sterling et all sf postulated worlds full of junkies, so many that society fell apart. Marxists had their nightmare fantasies, and when the world moved beyond tose conditions, they refused to recognize it, failed to adapt, and killed hundreds of millions to prove it.
The world just doesn't work like that, Hydrocarbons won't vanish overnight. They just get more and more expensive, and as the expense climbs, people come up with solutions.
The English burned up all their wood, then found coal, then found oil, and that is how things work.
It doesn't work by flying spaghetti monsters suddenly turning 90% of people into junkies, or sucking all the oil out of the ground in 5 seconds flat.
The biggest problem the world has is the damned fools that think they, and only they, can see the future, and if the world doesn't start working on their pet solution RIGHT NOW, everything is going to hell in a handbasket.
They refuse to believe that anyone else is smart, let alone smarter, that people have always found solutions, and that emergencies on a global scale just don't pop up out of thin air (except killer asteroids and rogue solar waves).
Give it a rest, smarty pants. Get on with your life. Stop living a daily nightmare, you will just scare yourself to death.
Infuriate left and right
The only reason IC engines are even competitive with the electric motor is because of the high energy density of the fuel carried on board. If you solve the energy storage problem for the electric motor, there is no way IC engines could compete. Not on efficiency, not on torque, not on emissions, not on noise pollution, nothing. You are held hostage by the fuel tank. Not the IC engine.
Of course, but that's been the case since the advent of horseless carriages, and shows no signs of changing any time soon ...
What you described is a standard diesel-electric engine, which is essentially a diesel engine with an electric transmission. The engine was not always constant RPM; in most models, you actually controlled your speed with the throttle to the gas engine; forward, reverse and neutral were controlled by electrical switches. That configuration was invented almost a hundred years ago because it was physically impossible to build a 55,000 horsepower mechanical transmission. Battery-based hybrid locomotives have come into vogue in the last 20 years for yard switching, and more recently as long-haul engines, and were an obvious extension of the diesel-electric concept.
I used to wonder like the GP about the absence of all-electric-drive hybrids. The reason why hybrid cars like the Prius and the Volt use an electric-mechanical combination transmission is because it is more efficient for the gas engine to power the wheels directly when you're going 70mph, since it's close to peak efficiency there anyways. Then you don't need a larger, more expensive electric motor, and avoid losses in the electric transmission whenever possible. On the scale of a locomotive, this is physically impossible, but in an automobile it is the desired configuration.
Making H2 from water using solar/wind does not need to be the most efficient method, it lasts as long as the suns fusion reactor.
It's clear that the process will also get better over time. A square meter of earth on a sunny day gets more than a Kw. A couple
of sunny days on an acre of land gets more than a barrel of oils worth of energy. More than 50% of the energy that falls on
desert area typically bounces back into space. The land area of 2 south western states could generate all the energy used
by humans at the moment. We can beam energy from space...
Besides you don't need to use H2 to create electron potential. You can distribute it easily enough, we have it ll over
the place. Getting it live solves a lot of problems. Less storage in vehicles, less mass to store it in vehicles, no
recharge time, no range limits... I ride on electric buses all the time, they climb the steepest hills around here
packed with people.
Electric motors are smaller, lighter and faster than comparable internal combustion engines. No unburned fuel,
no C02 emissions or others that have a negative effect on your living.
We use hydrocarbons because it's more convenient right now. Even when a better solution arrives we will not
change because we already paid for the ICE engines in our cars and want to get the ROI on them. Same
for producing vehicles. Companies want the ROI on plants, people, process. It's clear that we could
build out an electric grid to support EV based transport, it is just not economic quite yet. Vehicles last 50+
years, I see people still driving 60's cars. Even when we start switching it will take 50+ years to see a
major impact. Even then ICE cars will roll on for ages. Jay Leno still drives his steam powered
car on occasion!
The real question is when is it smarter to start changing? In the SF Bay Area the pollution ruins
the hiking during some parts of the summer. That lowers the value of living there, that lowers
the price some people pay for housing... It is a small health issue as well, it takes a long time for
us to get to dealing with activities that kill/damage a very small percentage of people. Also is
it smarter to change first and become the leaders in a new market? Then there is the cost
of buying fuel from overseas and what it does to our freedom here. Do we lower our standard
of living? Less money for health care, education? What about the war's? Would we have cared
at all about Kuwait? How many free people have died for it? Is that smart? What does it
do to our greater wellness? Would you be subject to so many security hassles? Is that
increasing or decreasing your freedom?
France has approximately 31,939 km, or 19,845 miles, of track. The USA has approximately 233,000 miles of track, or over twenty times the track that France has. But the USA is only about 17.7 times the volume of France.
The problem isn't that we haven't put effort into the rail system, the problem is that the continental US is so much larger than France. France is 543,965 sq kilometers; the USA is 9,629,091 square kilometers, or about 17.7 times the volume. By both rail-km and rail-volume, we actually have more track than France.
It just isn't enough -- nine million square kilometers is a huge area to serve, and it is area that developed at a rate that was different than the rate rail expanded. In addition, France's population density is hugely higher than the USA; you have 60 million people, about 110 per sq-km, while we have 300 million, about 31 per sq km (and actually, because we have very high density coasts, that number is way too high for the US interior and way too low for the coasts.)
France and the USA present two entirely different rail problems, and the same strategies can't be used to solve both. It's not practical to set up a rail grid that serves the USA in an equally distributed way -- it wouldn't save money, or fuel - it would lose money and waste fuel.
We would benefit a great deal by moving to dual-track on many routes (the US hiline is one good example... many trains sit and wait for hours in sidings because there is only one track in many locations) and of course, with all that area, hi-speed rail would be lovely - but again, with 17x the area to serve, the amount of funding we're talking about is simply staggering.
I've fallen off your lawn, and I can't get up.
What I see is: Significant increase in complexity - three piston rods per cylinder, six crankshaft attachments to rods per cylinder pair - plus piston rods on the outside of the engine block.
True, but: no camshafts, no timing belts, no valves.

The smart way to do it is not to push the metal through the water, but to get the water moving by pumping it around. It'll then carry the barges / vehicles without any particular fanfare. When you pump water continuously from one end of a canal system to the other (which can of course be directly adjacent to one another, and for transport purposes, incorporate locks so as to make the entire system continuous), the entire canal will move continuously. Anything floating on the canal will move as well, no extra charge.
Hey, that's brilliant. Instead of moving a few hundred tons of barge through the water and deal with losses from turbulence around the few tens of meters of barge, move billions of tons of water through a canal, dealing with losses from turbulence along the hundreds of miles of the canal and support plumbing. That should be way more efficient!
Ok, maybe that was a little too snarky. Sorry about that.... Still a dumb idea, but sorry for the over-snarkage.
