I have a old Hercules multi-fuel diesel I picked up cheap (and another that belongs to my father-in-law), I plan to couple each of these to a generator head, and I can have a multi-fuel generator... they may be weak for pushing a heavy 6x6, but they're good for up to 50kW of generator (waay overkill) would like to get a 6-pole gen head, to run at 1200rpm...
I have been in a few of them. Wife used to work for SI international. Here is my thought process on the issue. You have a home and the power goes out a generator is a great thing.

Your final location is the same one ya live at. A generator and the 500 gal fuel tank are great.
Ya live in the city/suburbs and it is time to leave..... Do ya take 100lbs of solar panels/batteries with an inverter or do ya take the 50lbs generator along with 50lbs of gas?

Do not get me wrong. Generators are great but in the long term the Solar/batteries will win out. just some thoughts to think about.
