 some guys have used things like marine bilge pumps
 they are trubine style pumps with a strait trhough flow path
 can move massive amounts of water with the larger sizes
 should be no reason no to use one of these

I have pondered the us of electric water pumps and I believe that they would
be beneficial in many ways:

First no thermostat would be needed, when the engine get's to operating temp
the pump would turn on..

Second the pump can run at varying speeds, while light cruising the pump speed
would be slower than at full steam, saving fuel..

Thrid the engine could theoretically warm up quicker as there would be no leak
past a closed thermostat and coolant wouldn't be circulating through a cold
engine...

Fourth reverse flow coolant systems could be retorfitted easily just by
reversing the current to the pump, no special reverse flow pump impellers
would be needed...
