I'm looking at a lot of these builds, and Youtube builds, and everything seems pretty straightforward if you just want to produce thrust from a nozzle. But what about if you want to build something like an APU, and generate actual electrical energy or even drive a shaft? Is that something that can be accomplished easily with these DIY builds?

So I'm looking at the pictures, and am wondering if I'm understanding the basics of this set-up right?  |

Yep , thats correct , the bypass was necessary due to the small size of the freepower turbine used , I used the same gas producer turbocharger as I did previously in my turbine bike www.youtube.com/watch?v=CplnY9TG7NE which was equiped with a "full sized" freepower wheel . The racing karting chain as used on the kart is horsepower limited as well as RPM limited , so a "small" freepower wheel was more than adequate to exceed both those limits. The bypass on the kart eventually had a suitably sized jet nozzle fitted to create the design backpressure on the gas producer in conjunction with that from the freepower wheel . |

Do you happen to have any good diagrams or other resources on how a free-power turbine can be built? |

jetandturbineowners.proboards.com/thread/680/diy-turbines just hit the icon/s in each section for the information , or checkout the various builds for ideas . The simplest way is to build a smallish gas producer and feed its exhaust through the hot section of a large turbo , but be warned , constructing freepower stages takes at least as much work as building the gas poducer and is the reason why they are few in number compared to pure thrust constructions , and if you want a high rpm gearbox for a low power output unit the problems get greater . What sized output are you looking at ??
