The colony

Been watching a show on discovery channel called the colony. Its a group
of people who are stranded in a warehouse area and they think the world
was wiped out by a virus and they are few survivors. Any how, they have
showed you can use a battery bank for power and recharge it with a
pressure washer and a car alternator. The cool part is, that they don't
has gas, so they created a system that burns wood, and then that wood
heats up wood in a smaller container and makes gasification. So no gas,
and burn wood, makes burnable gas fumes off the wood. They used this
back in europe in the world wars when gas was scarce. This show is gonna
be very useful.
