Air Powered Car, Round 2: Fuel Vapor

By Evan Ackerman

FuelVapor Ale

Yesterday I wrote about an Air Powered car, and based on the, uh, popularity of that post (which I will address in due course), here’s another type of vehicle that uses air to increase fuel efficiency. The new tech under the hood is called Fuel Vapor, and it’s able to increase the fuel efficiency of any gas engine by up to 20% while at the same time decreasing CO2 emissions by 30%, all without a catalytic converter. This is all apparently made possible by mixing air with fuel at a ratio of 20:1, as opposed to 14.7:1, which is standard for most cars.

Although the Fuel Vapor system can be installed on any gas engine, it’s flagship platform, the alé (that would be “allay,” not “ale”), is no slouch. The alé has a 180hp Honda engine and can accelerate from 0 to 60 in 5 seconds, with an electronically limited top speed of 140 mph. It corners at 1.7g on street tires, and at 92 mpg, can drive from Canada so San Francisco without refueling. Furthermore, it emits 75% less CO2 than your average hybrid. The initial run of these cars will be hand built and cost $75,000 (Canadian), with mass production predicted to bring the price down to less than half that in 5 years. A video, and more commentary, after the jump.

[ Evan’s commentary will make a lot more sense to you if you take the time to read the comments left on his previous “Air Car” article. -Ed. ]

Now, Fuel Vapor technology doesn’t approach the levels of cleanliness and efficiency that the Air Car claims to, but the upside is (and it’s a big upside due to sheer convenience) that it runs on normal gasoline and you can refuel it anywhere. As such, it’s certainly no solution to our oil dependency, but it’s a step in a positive (if perhaps not ultimately the best) direction.

So then, what’s the best direction? In my opinion, we’re shooting for safe, zero emissions vehicles, driven by energy from renewable sources. I am immensely in favor of this, and indeed, in favor of any steps (however small) in this direction. That being said, I think it’s important that each step taken is carefully thought out, and in our current media saturated (read: media biased) world, the consumer has to do a lot of that analysis on their own. The Air Car, for example, is undeniably a very environmentally friendly vehicle in that it runs on air, producing zero emissions. But at the same time, it raises questions that both the media (since environmentalism is so popular) and the manufacturer (for obvious reasons) seem reluctant to directly address… For example, where is the power to compress the air coming from, and how environmentally friendly is that? From a more general perspective, do we want to try and centralize our power production for maximum efficiency, even if it means depending more heavily on an aging and overworked power grid? Or would we rather decentralize into smaller regional or even personal means of renewable power production, even if they are significantly more expensive and potentially less reliable?

Questions like these are just the tip of the iceberg, and I don’t mean to try and answer them myself (don’t worry). The point I am attempting to make (and that perhaps I failed to make clearly in a certain previous post) is that these are complicated issues, and it’s far too easy to just say “wow, a car that runs on air!” and leave it at that (which is what mainstream media tends to do). There are no easy answers, and there may not even be “correct” answers, but companies like FuelVapor and MDI are making substantial progress in a positive direction and deserve not only superficial publicity, but also well thought out and carefully reasoned support.

    Isn’t this the same technology that’s used in the 2000-2006 Honda Insight (manual trans only)? They call it “Lean-Burn” and it is responsible for the 40% efficiency boost of the manual trans Insight over the non-lean burn auto trans models. It was also used in the CVCC models.

    Yeah, Evan! Cool find! I agree with your commentary on the air car technology. The question is, if this can be installed on current vehicles (as I believe I read), WHAT DOES IT TAKE to do that, and will the fuel efficiency be retained. Or, more likely, will the existing engine in my 2000 Accord be compatible with this technology without losing compression, top speed, reliability, or useful lifespan, or if it will present problems when doing regular mainenance. Will it be a bolt-on system that mounts onto an EFI unit or will it require the resuscitation of carburetors and distributors? I will definitely keep this thread in mind! BTW, any of you OhGizmo dudes hear about the technology a professor at Purdue developed that uses aluminum and gallium as a catalyst to split water into hydrogen for fuel-cell cars? He claims that converting bauxite into aluminum is 50% efficient, and that 2 Al atoms generates 3 atoms of H. Stoichiometrically it works. The gallium is unaffected by the reaction and can be recovered, and the Al2O3 resulting from the oxidation of Al can be reduced through electric means back to Al, or used as the ceramic powder alumina it produces. He says that you could just end up fueling your car with aluminum-gallium pellets and water. The electricity COULD, he says, be more eco-friendly by using wind, solar, biomass and other sources. Considering that an internal combustion engine car is about 15-25% efficient, and that this produces no direct CO2, and is probably safer than carrying compressed hydrogen in your car, this seems like a pretty cool idea. Anybody care to follow up on this and post?

    “can drive from Canada so San Francisco without refueling”. I don’t mean to be pedantic, but Canada is a pretty big place. The difference between a Vancouver – San Fran run is quite different from, say, a Montréal – San Fran run. 🙂

  • piers

    phrawzty, you ARE being pedantic!

  • A nice videfilm about the air car:

  • This is exactly what I expected to find out after reading the title Air Powered Car, Round 2: Fuel Vapor. Thanks for informative article

    You’re idiot :-(.

  • ade shanu

    thank u for thinking of the poor this is a very genious invention keep it up

  • Anonymous

    that is tight

  • fat man(jy)

    cool donutss

  • Aaron

    Sorry but many years ago Opel ade a fuel vapor car and it gets 376 miles to the gallon look it up! So Honda Im sorry but you must do much better than that!!!

  • man, that is a weir car. I was wondering how efficient this car is? I mean, how much CO2 does?

  • Who ever wrote this commentary SUCKS!!! I think they need to take a little bit of time and, take i jornalism class, because all your parentheses (are pretty annoying) to say the least, are not needed. GOOD DAY!

    these is the most coolest car i ever seen!!! How much does it cost though?
