I do have a couple of solar panels. The regular panel for the bus somehow got a bullet hole in it, but, even with a completely shattered cover glass, it still runs the room light for at least two days, if I forget to charge the battery. The cheap plastic panel keeps the motor home brightly lit all night, front and back. But it takes a long time to recharge the battery. It's usually sometime in the afternoon before I can plug in the little inverter, to power my Dremel tool or NST. The price of panels on EBay is down to $84, so I may order one or two more.
Good luck with your hydrogen candle. Try making a plasma diode, with a neo magnet for one electrode and a needle point for the other. At one percent of the cost of a fuel cell, the plasma diode might be better than trying to run a car engine 24/7 for a few years.
And I'm thinking about a water Fusor. Like Stan's spherical cavity, but with the positive pulses going to the shell, using pulses with increasing frequency and decreasing amplitude. More than a hundred people have built working Fusors. At 80 to 100 kW output power, no one has figured out how to extract the energy, which ends up melting the inner grid. So if water molecules are shot through the hot spot, maybe the heat will split them?
