F1 electric?
Heard a rumour, from a couple of sources, about F1 going hybrid/electric in 2009.
Which is pretty damn soon!
I don't know if it's electric regen/ supercap braking or more far reaching hybrid drivetrain.
Or if it's just hot air.
Anybody else know anything about this?

IMHO unlikely with only 1 year's notice

They're allowing regenerative braking which kind of suggests hybrid...

Surge power... sounds interesting... Very 2Fast2Furious nitrous!!!

What I've read in the engineering press is about flywheel energy storage. A flywheel is attached to the drivetrain with a CVT, you 'charge
up' the flywheel with energy during deceleration over a few corners and can then have the energy back whenever you choose by pressing a
'boost' button - a bit like a shot of nitrous. Should be interesting!

Interesting fia article - sort of confirms my conclusions from the rumours I'd heard (from recruiting attempts & component suppliers in
electronics industry)

Sounds like another component to go wrong to me....

From what I'm told, F1 batteries are not much bigger than PP3 size. Hybrids like the Prius are really heavy because of all the extra things.
Doesn't sound like F1 to me.

fia (in the article) are promoting regenerative braking, so it's temporary energy storage (e.g. supercaps) rather than battery. Also they
mentioned 44kg weight limit.
Flywheel storage is interesting - if they put it on servos they could dynamically control front/aft distribution of downforce during a corner!!!
(using gyro principles)

Bob, you're not hoping that the electric kitten will be eligible are you?

The first step energy recovery systems for F1 will be mechanical (as required by the regs, no electrical).
Look up flybrid or have a look on Xtracs web page for some info.
There FIA set limits on total recovery of energy in a lap, total discharge and a load of other bits. It also has to be driver controlled.
I expect to see a lot of problems.
This is all required by the 2009 season then from (allegedy) 2010 there will be other energy recovery permitted (hot exhaust gas etc) in unrestricted
quantities.
i think the FIA have gone about it the wrong way and the flywheel systems arent as applicable to road as other technologies, however mechanical -
mechanical - mechanical has less losses than mech-elec-chemical-elec-mech or mech-elec-mech.
on the battery front they cant really use them in racing as the charge density is too low. Although i think martin ogelvies new hillclimb car is due
to be battery powerd awd.

A friend of mine works for a composites company who make flywheels for F1 teams.
He is currently working on the flywheel for the 2009 regs. As said it will store energy for power boosts.

Flywheel energy storage could get very messy indeed in an accident...

Well, if it weighs that much, they'll just have to get even smaller midgets for drivers than they do now.

I think they will have ballistic jackets, but carbon flywheels disintegrate when the go wrong.
Think the particle size is small enough to have little impact energy outside the immediate locale.
