This one allows a hobby experimenter to work with the principle on a budget. I’m still looking for a 12 VDC unit in the 90-120 watt range. That would fit the bill nicely. I haven’t found any used scooters out there. Those scooters are going for about 100 bucks. The sweet spot for our usage would be around3-5 VDC at about 3.5 amps.
That would keep the heat down and the gas generation at high rate.
