Did you all see 60 Minutes on Sunday night, 21 Feb.about the Bloom Box?
The Bloom Box: An Energy Breakthrough? - 60 Minutes - CBS News
It provides homes and businesses with autonomous power so that we don't need as many power plants and power grid.
Could the Bloom Box technology eventually provide continuous AC power to RVs while Boondocking? It seems possible. Home costs will eventually be $3K for a unit. An RV unit should be smaller and hopefully cheaper.
All is needed is air, heat and natural gas (propane?) to work the fuel cell. A small module for an RV could be enough AC to power an air conditioner, lights, pumps, fridge, TV/DVD, etc.
