quote: As for Biofuels, I find it very disturbing that nobody addresses the problem that our fresh water supplies are already maxed out. There is no fresh water to supply the enormous requirements that growing biofuels on a significant scale would require. Nor is soil erosion losses addressed. To achieve economical yields per acre requires intensive tilling and soil loss rates at 1 inch per 10-20 years. Topsoil replacement rates are around 1 inch in 500 years. It's sacrificing our future farm land for fuel, it's not sustainable. If you go with covered aquaculture your infrastructure costs go up and you might as well go with solar panels. The only viable biofuels growth areas seem to be the oceans.
quote: Being cyclical is not enough.
quote: And that still does not solve the question of how to store the hydrogen in the car.
quote: The catch is that hydrogen is dangerous to store both at fueling stations and aboard the vehicle.
quote: This allows for a VERY lightweight frame which can last for literally millions of miles
quote: I could go on for hours about how promising this technology is.
quote: What? You do realize that a Fuel Cell DOES weigh something as well? And you will still need an electric motor? And the Voltage Converters and Likely a significant Super Cap or Battery to give level set?
quote: You sound like you need a deal of reality.
quote: When I said current storage technologies, I did not limit it to those in the market/production.
quote: it will beat the pants off of current internal combustion designs in every measurable way.
quote: I've seen figures as high as 90% for hydrogen fuel cell
quote: A technology is not "proven" until there are actual production parts
quote: Your counting you chickens a little early there.
quote: In automotive applications, I have seen no number higher than 50%
quote: It doesn't have to be on the mass market to be a proven technology.
quote: Look how far the gasoline engine has come
quote: To be proven, something must absolutely demonstrate the ability to perform in its target area.
quote: Seems to me that a Mass Market, affordable, BEV or PHEV is beating the best Fuel Cell Car by nearly 40%!
quote: m, no it does NOT need to be on the mass market to be a proven functional technology.
quote: I'm looking forward to any solution that would free us of those binds, really.
quote: the problem lies in the fact that hydrogen has to be COMPRESSED considerably to even hope to match the storage capabilities we expect from gasoline. this compressed state makes hydrogen MUCH more dangerous than gasoline, should an accident occur.
