hi jemma; i enjoy your way of looking at the possibilities of these little engines. as soon as i can i will try nitro idea, the sterling is beyond me. again you go girl. mitch

Jemma, Always thinking outside of the box that is so cool. I never get these cool ideas my brain is always confused with other Crap lately.

The only think I see that would cause me to wonder is the extra weight of the components not the generator but the battery it charges. It might be good to run a lighting system while the bike was moving but I wouldn't try to store the excess. The weight of the storage would probably cancel out any good from the generator.

Lights and horn now there's the ticket.

but if you are running a hybred the battery is already there.

I have run ebikes they call hybred but they have no heat source. I have never run a gas and electric bike. I would think they would be terribly heavy and hard to manage though.

what i meant by hybred is an e-bike with gas motor like augies idea. i would think that to be an ideal situation or close to it. mitch

Maybe if you wrapped a length of the exhaust with a coil that heated vegetable oil and fed into a small resevoir you could use this heated oil as the expansion side of the engine and use some fins on the air cooled vacuum side.

Then the stirling engine could keep running even when you are done riding and could then charge the batteries over a longer period of time.

Running the stirling engine on a shimano hubs an idea I've kicked around awhile. But I've only worked with beer can engines myself and have yet to make that much power, but I've seen engines that could and would probably benifit from one.

These engines get pretty big and make little power to size, but , it really aint that necessary to make huge watts when these batteries will only absorb so many watts per hour anyways. Maybe a smaller output but long lasting and "FREE" generator would be good? interesting.

Cool idea... last one I thought I'd see here but you made it apply. Rock on.

Here is a hybrid in the works at Staton-Inc...

It will be pricy but should be well done when he does it. The technology is here we just need more people doing the builds. I am not the right motor/engine guy to do the early work but will jump on board down the line when I can understand it enough to do it in a repair on the road situation. They are heavy and will use extra energy for now.
