Well, they’re sort of home-built generators… it just takes any unused gas mower engine, an unused but functional alternator, and the right physical connection to get them together. These guys have the instructions and the brackets.
Pretty neat in a geeky+redneck sort of way. (well, geeky & redneck are my kind of people after all)
I’m thinking one could easily rig up a cart to stack the generator & batteries on, and even add a medium-sized solar panel to the works with appropriate charge controllers.
Yeah, you could probably do better with commercially-available 2KW generator, but this way you’ll have the pride of taking some old, disused stuff and putting it to work.
I feel a winter project coming on.
