I've often wanted to play around with the idea of using TMGs to harness the engine heat to generate electricity instead of using a stator. I build Stirling engines as a hobby, and a TMG is basically a Stirling cycle. Probably be too heavy to make it worthwhile, but even smaller systems could at least charge the battery, taking that load off the stator/engine combo.  I have some Peltier thermochips here I have been wanting to attach to my muffler to provide electricity for heat and air conditioning on a bike or a car. You can put them in a suit or blow air over them. These are the same chips found in electric heater/cooler units. I have been keeping that under my hat but if people are interested in experimenting I would be glad to discuss it.  |

Pretty sure you'll need to run them charging a separate battery system, but it's a very interesting idea! Probably best to start a new thread about it in Custom section or perhaps Tips & Tricks section. Don't want to hijack this thread more than we have. |

John Costs depend on power needs. You can get them from $5-$5,000 depending on your needs. I have not thrown together a circuit design that would do anything for a scooter, so I can only guess at current costs you would need to spend 1-2 hundred to make anything worthwhile. Though you may be able to power running lights and turn signals off this with a very simple and cheap design. I could be very wrong. You would need a separate battery for most applications, size depending on what you are powering, and some form of R/R. There may be off-the-shelf systems in place, but I haven't seen any I can report on at this time. Do a google shopping search for peltier tiles to get an idea of price to power ratios. Note- such a design could prevent the need for stator upgrades in some situations. |

and with so much led stuff out now for most of the lighting including headlights, drastically reducing the power consumption, i think stator upgrades aren't as needed as they once were. even for me, it's mostly because i have wanted to for a while, not that i currently needed to.
