Very cool, Maniac.
Looking at your pics, first thing I thought of was the DIY, bike generators.
Could run an alternator (cheap or found) to run truck fan or an electric radiator fan. (would look so roadwarrior!)
But could double as a generator for black outs to run a light, radio or TV. Would also give load if you wanted to run em longer. Be a great way to pre stretch drive chains. (I hate tensioners)
LOL, sorry. to much coffee. But I am gonna dig out an old 2 smoke build and think about this.
Is that a shopping cart? 2 funny. Waste not want not and looks perfectly suited.
