My house is not set up for natural gas, so I bought a gasoline fired generator and converted it to propane. Propane is much safer to store and does not go bad.
I then bought the necessary equipment to plug the generator into the house. This equipment takes the house wiring completely off the grid, so I do not have to be concerned with electocuting a lineman.
Now if you figure out how to make producer gas aka syngas, and have a woodlot, you’ll be all set.
I did the very same thing. A 6.5 KW unit handles everything in my home but the central AC.
