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.

In keeping with the “earthdream” color scheme for their F1 racers, Honda has been trying out a hydrogen-fueled car, the FCX, with selected customers in California. The styling is a bit retro, boxy and unimaginative but, when it’s alternative fuels that matter, who cares about the car’s looks?

Well, it seems Honda does. They have been showing off a new body for the FCX that is much more up to date and stylish. Called the FCX Concept, it has the usual modern grin for a grille and swooping lines everywhere.

I must be getting old - to me it just looks ugly…

TVR used to be a very small company that made typical British sports cars - in Blackpool, Lancashire, of all places. They followed the same formula as all the other constructors: lightweight fiberglass body on a great-handling chassis and a lightly-tuned straight-4 to provide the power. AC broke away from the norm when Carroll Shelby squeezed an enormous American V8 into their Ace to create the Cobra and that gave everyone the same idea - why not do the same for other Brit sports cars?

It was tried with a variety of cars and TVR were no exception, but nothing earth-shattering was created until the eighties, when the company was bought by Peter Wheeler, a millionaire with big ideas. He wanted to make TVR into a “serious” sports car manufacturer.

The result was a series of models that multiplied to the point of confusion. They all had one thing in common, however - they were ridiculously overpowered and a handful to drive as a result. Until the Sagaris of 2004, that is.

The styling is very TVR, aggressive and slightly over the top, but at last the company had produced a car that could handle the power delivered by its 4 liter straight-6. And the result was a car as desirable as any of the great Italian supercars at a fraction of the price.

Well, Jeremy Clarkson seems to think so, anyway…

Back in the nineties, Sony released the PlayStation game that changed console racing games forever: Gran Turismo. It was spectacular in its realism, with detailed graphics and seemingly true-to-life handling of the numerous cars it was possible to sample. But then, in 1999, they released the follow-up, GT 2, and we were introduced to real tracks to play on.

Very quickly one track became the favorite, the mighty Laguna Seca, and it did so by virtue of one corner - the Corkscrew. A sharp left after a rising blind crest, a drop down at an impossible angle and a swooping right, that was the Corkscrew; it tested games players to the limit, especially when driving one of the ridiculously powerful cars included in the game. I am still proud of the fact that I did eventually learn how to get the Toyota Le Mans car through the Corkscrew without careering off for a meeting with the barriers.

But what is it like in reality? How does the game compare when you are in a powerful car attempting a quick lap at Laguna Seca?

Thanks to Top Gear and YouTube, we can find out. Have a look at this clip - Jeremy Clarkson trying to get a Honda NSX within reach of a respectable lap time.
