I think this would be a great thing to not do.

KERS Drag Racing

KERS = Kinetic Energy Recovery System

The main challenge of flywheels in cars is that the gyroscopic forces affect cornering and/or suspension, depending on orientation. This is not really a problem in drag racing.

I fully understand that no high-octane fan wants this, but it would be awesome to see teams from MIT et al tear up a quarter mile powered by washing machine parts and phone batteries.

       A pair of contra-rotating gyros can be used to cancel precession effects, though the forces on the containing structure are fearsome.   

       The vehicles will be interesting - ultra-light, apart from the huge flywheels and transmission; electric drive might be best.

       I think this was the theme for an episode of scrapheap challenge. They didn't go very fast.

       The clutch would need to be huge.

       I think you would probably need a CVT of some sort, or even an IVT (infinitely variable transmission; I have read about one, but I can't find a link...).

       Files?

       Presumably, high-friction devices, to grip the surface when the flywheel contacts it.   

       Note that the forward velocity of the vehicle can never in that case exceed the initial circumferential velocity of the flywheel.

       I thought we did this one once... man-powered though if I remember correctly.   

       Somebody posted a link to SSP racers.
hmmm maybe I can find it that way.
  

       Nope. Either the idea has been deleted or I'm just switching Universes again.   

       Anyway, here's the SSP Racer, (my brother and I got these one year for Christmas, coolest toy ever) [link].   

       I posted an idea like this years ago, but not in the motorsports category because, I thought, no motor. I like the change from babes in bikinis to MIT nerds, a sign of the times.

       This is really damned clever. Would make a great TV spot on one of those fun science shows like "Outrageous Acts Of Science" or "Mythbusters".
