 Yes something like that might work. It has been done with other
 dual power sources driving the same load. In a way a center
 differential in a 4 wheel drive vehicle is somewhat the
 same principle in reverse.

-----------------------------------
Similar to the drive in a Toyota Prius Hybrid electric car. They use a
planetary transmission, with the engine driving the sun gear, and an electric
motor driving the ring gear, with the car driven from the planet.  By varying
the electric motor controls, it can be a generator or a motor, absorb power
or boost power to the wheels.

BTW Bill, did you get a chance to plot the latest water flow data
for both evap core in parallel?
