Looks good for robotics applications. The power density is comparable to the low end of brushless motors, and it can use hydro-carbon fuels which are about 25 times more energy dense than current batteries. At 3 hp, it might be a reasonable drop in for the type of weed-whacker two-stroke that drives big dog.

This is certainly something to consider, and for robots or exoskeletons the power density would make for a pretty compelling solution. I'd be curious to try out its low RPM torque, that was always a challenge on the RX-7, starting in first gear you spun up the engine to 2 - 3K RPM before you let the clutch out.

How many watts can you reasonably generate with 3 hp?

[userbinator]

Approximately 2237.

I was going to nitpick about efficiency of the generator not being 100 %, but apparently a generator can be 99 % effective.

[ChuckMcM]

Yeah, if you start from the break HP of the motor, pretty much all the work can be converted into electricity. If you start from the energy in the fuel, and go all the way to the generator, its like 50%.
