Jeff, another solution to diversifying your energy sources/fuelsources, would be to find a way or individual to convert your gas powered engines, to hydrogen powered. Granted it appears that most people that have done this have disappeared after. You are a resourceful and brave enough to make it happen. This may be a better option, than resorting to using an electric vehicle, powered by a potentially explosive battery, that you can't put out if it catches fire.
