Roger Leir did it and you can too – There’s a $10 million prize waiting for the person who can design a car that gets 100 miles a gallon, and one engineer has modified a 1993 Geo Metro that he claims can do just that. Other researchers have found a way to convert ethanol and other biofuels into hydrogen very efficiently.

A new catalyst makes hydrogen from ethanol with 90% yield, at a workable temperature, and using inexpensive ingredients. The new catalyst is much less expensive than others being developed around the world, because it does not contain precious metals, such as platinum or rhodium.

We all know the polluting problems with gas-powered cars, but hybrids have their problems too. Now Honda has achieved something that many people thought could not be done: designed a hydrogen-powered car.

But don’t run out and order one?BBC News reports that Honda plans to manufacture only 200 of the cars over the next 3 years, starting in July, and at first they will be only available to lease. The first 5 customers have already been chosen and they?ve all from the LA area, where there are actually hydrogen fueling stations. The first person to get one? Actress Jamie Lee Curtis.

Meanwhile, another Japanese company has designed a car that works on water!

UPDATE! – Most scientists have dismissed the possibility of running cars on hydrogen, even though it would be the ideal fuel, because of the difficulty of storing hydrogen, due to the small size of the molecule and the need for extremely low temperatures. But now a room temperature storage material has been invented that could revolutionize the lagging fuel cell industry and jump start the move to the use of hydrogen not only in automobiles, but in fuel cell applications of all kinds. Even home heating and power generation will fuel cells becomes a possibility. Keep reading for update.

Aside from the cost of producing hydrogen, the problem of containing is what’s stopping the widespread adoption of this fuel. Since it is a single molecule, it is so tiny that it cannot be contained by a conventional automobile gas tank, for instance. But if we could design motors that manufactured more hydrogen as they ran, similar to the way hybrid cars manufacture electricity to recharge their batteries, hydrogen could become a viable alternative fuel.
