WOW, looking at those photos gave me goosebumps!
Hmm, depends what actually needs the 3-phase power. There
are home-made and commercial rotary phase converters. Great
for motors, but you need to work on them carefully to make
sure they are balanced well enough for electronic loads.
The motor loads help balance it better, but the electronic
loads cause the generated leg to sag.
