spoke to bill about it: the cylinder is basically a dead short (it's 2
cylinders, one inside the other, around 10in high, 5in diameter).  he's had
it up to 1000A (once!) but the problem is heat.  the system was designed
not just for electrolysis it was designed for thermal dissipation without
mechanical parts.

he's going to do a test at 1000A again, see what the thermal rise is.  if
it's below what would normally be an emergency braking time then we're fine.

although what he actually said was, "time to blow shit up again" :)

yehyeh.  oo the wikipedia page animation is nice. twin cranks offset by 90
degrees, oooo :)
