Forgot something. You can also purchase stationary bikes to produce electricity for recharging batteries via pedal power. Not real practical for powering your home, but enough to recharge small electronics, like laptops, cell phones, video players, radios, and such. You could charge deep cycle batteries with them and use an inverter for low drain items, like HAM radios for communication.

Also, those solar yard lights are pretty handy for a few reasons.
1. They can provide light at night, obviously.
2. They recharge AA batteries. You can remove those batteries in the evening and use them to run other things, like your cell phones and such with the right adapters and conversion units.
3. They are fairly inexpensive, considering they are also a battery recharger. Having lots of them means if one breaks down, the others should keep working. Redundancy.

Lastly, you should figure out a way to get your vehicle to recharge your deep cycle batteries as a backup way to recharge them. If you make wood gas and you run the vehicle on wood gas, it would make sense to bring a few deep cycle batteries with you when you drive and recharge them on the fly.
