hmmm. I have no screenshots, but hydrokinetic and soloar generation does ... suggest the distribution of power via a bus.
The technical issue I havnt come close to solving is for solar - the output speed is constant, but the torque changes with the sunlight level. Theres a lot of scope of an adaptive programmable gearing to distribute power efficiently from solars over a range of lighting conditions.
I am resisting the entire fueled engine side of things, (including jet fuel) as I feel the results - "one engine" per machine - are somewhat boring.
