Max Mosly said Heat energy recover will on before 2013, but how to do it on F1? I don't think they'll put a steam engine on F1......

The most efficiency Heat energy recover system on automobile is GM's heat > electric chip in exhaust. it not enough to supply power to drive the car, but it can replace the generator while full engine load, it can save 10% power. So, it can make the wheel have more 10% power.

If the F1 engine have 700ps before, it will get 70ps extra power.

but.... it still not changh the heat back to kinetic energy...........

i read a while back that bmw have a heat exchanger system for the exhaust that developes steam at a fairly advanced stage for their road cars and they have a way of harvesting that for power or extra fuel economy but , and this makes a mockery of racing improving road cars, they won't release it yet so other f1 teams can't buy a road bmw and look at the system

Just attach a nozzle to his mouth, they should have more than enough hot air to power all the F1 cars for the season that way.

Two ways, that are basically the same.

When the cars brake, the braking energy is disspated as waste heat.
The idea is that you connect the brakepads to a small wheel that also touches the brake disk, starting that small wheel to spin. That energy is then transfered to a battery, starting a small electric motor that helps the car accelerate. The idea that when you brake, some of the brake energy is harnessed to charge a battery that will be then discharged at corner exit for extra acceleration. Think kinda like those bike-lights that attach to the front wheel.

The other way, is a mechanical: when the brake pad touches the disc, it starts a small wheel turning (same method as the bike-light), but that is transfered mechanically (via cogs, axels and the like) to a large, heavy disc, and starts THAT spinning. Then when the car starts accelerating, that big spinning disc is connected to the drivetrain, giving extra boost to accelerate.

Think of an upside-down bike: If you crank on the pedal, until the rear wheels is spinning pretty fast, there is a lot of energy stored there, right? if you try to stop it, it can hurt, right? If you right-end-up the bike, it will move forward a bit.
Now think of a rear bike wheel being a lot heavier and/or spinning MUCH faster, and you got the general idea.

@Stigpt: That's basic KERS you're talking about. scania is refering to a way of capturing waste heat from all parts of the car.

...ok, so the bestest way to make kinetic from thermal is?...

you means they really use a steam engine?

Best idea so far.

With a thermoelectric generator: http://en.wikipedia.org/wiki/A ... Thermoelectric_Generators

No steam required.
