| Sep 2, 2014 at 15:14 | comment | added | RedGrittyBrick | @Skip: Interesting Q. I think it would be surprising if an engine primarily designed to produce thrust would generate electricity more efficiently than an engine specifically designed for that purpose. But the APU may be optimized instead to reduce weight I guess. | |
