')If people insist on watching cars go in circles for hours on end why not use it as a full scale testing ground for solar cell, electric and battery innovation?
They do. F1, from this year on, will field KERS, a "Kinetic Energy Recovery System, which reads Toyota Prius and Honda-style (funny enough) hybrid battery systems.
Funny enough, the teams dislike it and say it will make cars slower, because it's heavy and stops them from having some play with weight distribution. But just you wait until someone there gets an idea on how to get it to work as an advantage for performance (and that means batteries and systems' efficiency will increase quickly), and we may be into something.
WTCC cars run, from this year on, on second-gen biofuels - trash made into petrol. They also allow turbo diesel engines, which are more effcient. So much that SEAT won the titles this year, on a TDI engine.
Back in the 1970's (I think), Le Mans was run on fuel-limit rules. Cars got a max allocated fuel amount before the 24-hour race, and had to make do with it. This regulation was killed, but the fact is that, in endurance racing, efficiency is very important. Audi has won the last 3 24-hours on TDI engines, and only Peugeot (on a diesel with particulate filter) came close to beat them. They're both upping the ante or next year, with more efficient cars running smaller, more efficient turbo-diesel engines.
In essence, racing cars is about efficiency. Engines are more powerful the most they can get out of fuel. Fuel efficiency is essentially what we can crave these days, and any innovatio coming forward is always good.
