I've built a few power assist trailers with a gas engine and alternators to play the hybrid role. The big one supplied 12v,24,36v up to 50 amps. It also has a 1000w 12 to 110 inverter and a small aircompressor built in. The brakes on the trailer are inertia operated and even though the trailer was pretty heavy my trike would pull it without a problem and since the brakes are auto I can barely tell it's back there when braking. It has a 6.5hpharbor freight honda clone engine turning both a 12v and 24v alternator. The wheels are modified solid wheelchair tires with homemade stainless steel hubs. This thing is also my hurricane emergency power and here in NC you need some kind of backup as we get them every year as a rule. ( this year we got lucky though -NONE!)
Hear is a pic before the outside covers and the air compressor was installed

finished with sides installed. They are held on with velcro and are removed before running it.
this is the brake layout
layout of wheel assembly Made the hard way!
It would power the 750w motor on my trike without a problem and would run for about 3 hours on a tank of gas (about 3/4 gal)
