I appreciate you want to find new uses for hybrids, but you have "emergency" shelter/kitchen/power/shower/crapper WELL in hand already.
It was a birthday present for my wife. Little did I realize her health would soon reach a point where she doesn't want to go on trips. Still, this is what it looks like with the Prius:


I see our Prius as being the start of a co-generation system. As I've been building out the emergency systems, I'm moving towards a day when:
  • natural gas - non-traffic fuel source already available at house for economical rates.
  • electricity - the current two-stage inverter can be replaced by a single stage using the built-in, inverter to generate true, sine-wave power.
  • heat - using the exhaust heat for hot water and in the future, absorbtion cycle cooling.
I want to exploit the engine waste heat and stop just burning natural gas for heat without getting some electrons.
