Can something like this be done, with batteries, at a smaller scale? 48-60v battery bank. Are small 3 phase 240v generators available? How about the inverter? I know 240v inverters are available, but are they three phase?
I am thinking of our 15,000 lbs sailboat.

Harmony was an early Solomon beta conversion. After paying for the system twice again in repair bills, the owners tore out everything and went for a twin generator set-up. Every Solomon component was running at 100%, so when one system went out, the rest got strained to failure. The owners are neighbors of mine, and we've often spoke of the practicality of battery powered boats. 12 to 15kwh seems to be the limit of practical weight, then a genny after that. The original 6kw drives whacked the battery so hard, the original battery charger would overheat, low voltage would cause more throttle demand, the slowed motors baked and shorted. Now there are no traction batteries, with the original battery bay converted to an extensive house array. AC inverters run the cooktop and AC, twin gennys ensure reliable power. Every part is off the shelf Grainger. Grainger even extended a world-wide warranty to them, ensuring simple service.

There are a couple of videos (youtube i believe) that show "Harmony's Electric Propulsion"

would anyone have any additional information on this particular system. I can't seem to find anything other than the videos and i am very curious about the motor.
