A fluid driven differential, having a fluid filled housing, an input
shaft, and a pair of output shafts. The input shaft is attached to an
automobile driveshaft outside of the housing and to a propeller inside
the housing. The output shafts are each attached to an axle and wheel
outside the housing and to a turbine inside the housing. When the
driveshaft rotates the input shaft, the propeller generates a fluid
current that turns the turbines and thereby turns the output shafts, the
axles, and the wheels. A pair of return conduits direct fluid from the
vicinity of the turbines to the vicinity of the propeller.
