A professor at Purdue University, Jerry Woodall, has found a method of producing hydrogen from aluminum alloy pellets and water. This is very important for the motor industry as it promises to solve many of the problems that confront the introduction of engines running on hydrogen as a fuel.
Although hydrogen is the perfect alternative fuel, its exhaust containing nothing more harmful than water vapor, its use has been dogged by a bad press, with memories of old airship disasters like the Hindenburg, the problem that generating it by electrolysis uses more power than it produces, and the difficulties involved in storing it in quantity. The Purdue solution offers a way around all of these, suggesting that cars of the future need only fill up with the alloy pellets.
Hydrogen is generated spontaneously when water is added to pellets of the alloy, which is made of aluminum and a metal called gallium. The researchers have shown how hydrogen is produced when water is added to a small tank containing the pellets. Hydrogen produced in such a system could be fed directly to an engine.
Gallium is an important ingredient since it stops a skin of aluminum oxide forming and protecting the metal from further reaction with the water. And the by product of the reaction is hydrogen…
The Purdue Foundation has applied for the patent to the process and plans are in process for its commercial use.

Warwick University’s Eco One
The WMG students at Warwick University have designed and built one of the greenest cars on earth, the Eco One - and it’s made from potatoes and cashew nuts, amongst other exotic materials. Amazingly, it’s a racing car capable of 150 mph and runs on bio-fuels.
The ultimate aim of the students’ project is to build a car that is ninety-five percent bio-degradable or recyclable. The Eco One is just the beginning, it seems. But it does show what is already possible in this field of research and points the way for manufacturers of green cars in the future.
The Eco One will debut at the Sexy Green Car Show at the Eden Project between March 30 and April 15, where it will stand alongside the offerings of some of the largest car manufacturers in the world. To learn more, visit the Warwick University site or read PitPass’ article giving the racing view of the project.

In an earlier post I mentioned that, sooner or later, we are going to have to get serious about electric cars. Fossil fuels will not last forever and will have to be replaced by an alternative, most likely hydrogen or electricity. GM’s Hy-Wire is an elegant combination of both that may well show the route to the future, but Tesla have the best answer yet from the electricity side of the debate - their roadster is completely electric and powered by their own design of battery.
The electric motor has obvious advantages in that it is clean, light and quiet; but it also presents us with great problems. Power similar to that provided by the internal combustion engine is necessary before we will consider it as a valid alternative; a big problem in the past has been that any practical electric vehicle will have to have a similar range to gasoline-driven cars before we will be persuaded to swap; and the origin of the power that recharges the batteries remains a stumbling block as long as we continue to get most of our electricity from power stations burning fossil fuels.
Tesla have solved the first two of these problems - their roadster accelerates to 60 mph in 4 seconds, surely enough power for anyone, and has a range of 250 miles, which is very close to the average for a standard production car. As for the power stations, I guess that will have to wait until we face the fact that nuclear power is the only viable answer.
If you want to learn more of the technical ingenuity behind the Tesla, visit the engineering page on their website. And, if you want one of next year’s model, get your order in now - the 2007 batch sold out in four months.
Update:
Here is a link to a video of the Tesla being driven. It also has more detail on features of the car but listen to it when in motion - that is the sound of tomorrow!
And another video just for the Brits…
