When you get to the REAL horsepower, Paul, let me know. I'm gonna start saving up for that like yesterday!!!


hahaha!

Well, maybe higher current at 144 or 156v is doable, but much higher voltage means departing from mosfets and using IGBTs. Maybe with a bigger, longer copper block, like say 12 or 14 inches long, and inch wide, with say 14 or 16 mosfets/diodes bolted to it, and the block has a U shape drilled through it, with water being pumped through it all the time, I bet we could get those mosfets/ diodes up to maybe 70-80 amps each instead of 50 amps each?? It sounds sort of naughty, though. 16*80 is what??? 1280 amps??? We would definitely want to prototype something like that at a smaller scale, like 1 or 2 in parallel, with a little baby liquid cooled cold plate. That sounds awesome! Then we could crank up the current until something exploded or caught on fire, and then we would know how much power we could get, cheaply! ya!
