I would love to hear more.

Understand these are 'back of the envelope' and it will take me a little time to get everything tested:
- tap traction battery - following Richard's example, I'll be using standard NEMA plugs, basicly 220 VDC, 50A plugs.
- drive spare inverter - using a microprocessor, operate a spare, Prius inverter to generate 3-phase, sine-wave, power.
- power transformer isolation - this will feed the house and keep the Prius power loop properly isolated. This will also handle code and safety issues (DO NOT POWER THE GRID FROM YOUR HOME!!!)
At this point, we have whole house, emergency power. If the power transformer and house interface is mounted on a trailer, it becomes a nice, emergency generator. But for co-generation, the following has to be developed:
- retrofit Honda natural gas injectors - a tricky problem, there are non-trivial technical issues to address. It is also important to have a safe, flexible hose from the gas supply. It would be easier to use tractor gas but putting it in the tank would be illegal.
- flexible hose, hot water exchanger - fitting over the exhaust pipe, it captures the available heat and vents the exhaust out a safety pipe.
- quick-connect to ICE coolant exchanger - only 80C, still there is no need to waste radiator heat.
These last three elements are the trickiest but critical to co-generation. We need to run the ICE off of natural gas, a tricky but not insurmountable problem. Also, we need to capture as much waste heat as possible for space and hot water heating.
