I once had this blogged in my watsonseblog, but I haven’t blogged it here. I’m trying to charge this Maxwell ‘Boost Cap’ or ultracapacitor with a solar cell, but the problem is that this cap is so ginormous that it takes a very long time to charge when the solar cell is putting out 100 milliamps or less. That assumes a bright sunny day, even longer when it’s cloudy outside.
