Louis Devault Posted 6 months ago portable green power source not involving wind or solar yes I know of a couple of applications in use right now. Ingersol rand introduced a few less sophisticated brushless motors to market in 2008. Others who wish to remain nameless have also developed their own self sustaining motors but without loads that are significant. One model I have seen is operating a generator set and is using a dc power supply to power the brushleess motor. The generator set is cranking about 15o amps at full load while the brushless motor is only consuming 9.6 amps. A 1 to 15 ratio is pretty good don't you think?
