Behold, the monstrosity that is BrickScooter:

Oh Hai, Bricks! |

The structural bits are made of machined aluminum plate, and the front fork is a stock Razor A3 steering column assembly (complete with stock wheel!). Motor is a Turnigy TR80-100-B motor, nominally rated for 6500W@130A, but actually good for quite a bit less in vehicle duty.
The bricks are mystery Semikron MOSFET modules. Because they were a custom run for GE, they have no public datasheets. Empirical testing says they are 110V, 2 mOhm, and given the usual brick dissipation of 1KW this puts them at 300A.
Why does it exist? I haven't a clue. I suppose motor controllers and scooters are very popular at MITERS, where I spend much of my time. And I like high power stuff, and bricks, and designing nice controllers for things (I'm intending for this to have sinusoidal output and current control).
Also, I fully intend to win the 2.007 drag race with this thing. A hundred amps and a full Melon should be hard to beat if I can get the mechanical stuff right.
