RE: TORSEN's er what

[Reiner Fink <reinerf@microsoft.com>]

I believe that this is done thermally. Standard viscous diffs work
beause the side that is spinning more heats the fluid, increasing its
viscosity and thus shifting power to the slower moving side. By adding a
few thermocouples and a resistance heater, you should be able to control
the viscosity of each side of the diff independantly. Wa La! Adjustable
bias.
