Would two large capaciters be cheaper than batteries to drive an electric
car. Say a couple of 2 farad capacitors. Capicators would recharge faster
too.

No. The energy density of capacitors will always be lower than
chemical batteries. Electric fields across insulating layers cannot
compete with chemical bonds.

They'd discharge faster, too. As in a fraction of a second.

Yes But it would be quite a ride for a second.

--Sounds like someone from sci.physics.electromag might be fun to
talk to. 2 Farads would be a good start for a mass driver, heh.
