Yes, in a co-generation mode. My plan is:
  • 1/3d of heat energy - 120/240 AC for house power
  • 1/3d of exhaust heat - hot water and possibly cooling
  • 1/3d engine compartment heat - the lowest quality and a risk to engine cooling. However, reverse direction on the radiator fans could produce a nice warm breeze for the house, space heating.
What this means is every morning, the car will be warmed up, the house utility bills will shift to natural gas, and I can go to work. When I come home in the evening, I plug the car back into the house and life is good.
