Waste Heat from Exhaust
Has anyone considered making a heat driven motor or a 50 / 50 heat, exhaust gas motor to drive an alternator? Base the idea on a rear end of a turbo. But use a blade less rotor such as a Tesla turbine for reduce power loss from the engine. And the heat driven motor could use the waste energy from the exhaust tube to drive the alternator. While the waste heat is not free it certainly wasn't being used to begin with.
Just a thought I know nothing |
Yep
Yes, I've thought of using a rear mount turbo to power an alternator. I just haven't had the time--hoping this winter. I have a Dakota so there is plenty of room under there.
My plan, though still in the thinking stage, is to find a salvage yard turbo, plumb it into the exhaust, machine a collar to mate it to my alternator shaft, extend the wiring, and replace the engine acc. drive belt. I think it'll work. If it doesn't, it should be easily reversible. |
Don't turbos normally spin at around 10-15k?

Yea so whats to say you couldn't run a steam turbine from the waste heat @ the inducer and the rear turbine off the exhaust to assist in spin. Hook up some brushes and see what happens @ 15k.....?
Sounds like an abilty to make some power just dont know how much as of now. And the vapor mix coming from the inducer side could reduce exhaust temps while staying hotter than from the reservoir. Then be recycled to the steam side @ the manifold. In short scavenged energy from heat and from exhaust flow turned into current to run a Hydroxy (HHO) Generator thus eliminating the draw from an alternator and giving you increased efficiency vs break even or reduced efficiency for HHO production. Just built a test tube HHO generator and got 500 ml in 30 seconds. Working on a full scale for better production. la 8 P.S. go to a semi truck yard or semi truck turbo repair. You can pick up a test turbo and its huge (from the throw out pile) for around 50 bucks. It wont be in perfect condition but it will allow you to tinker for far less. When you find one wiggle the nut at the front and back for play. If it wiggles don't buy that one. Get one with tighter tolerances. Also if you plan on taking the thing apart get them to show you the proper tools you'll need before you leave. |
I like the idea of using the exhaust gas for a half-turbo to belt-drive an alternator. Sounds like ther eisn't much complication compared to the other ideas. Using exhaust HEAT to run some heat-engine to turn the alt would be the next step in my opinion, but that is a factor more difficult than the previous idea. using a turbo or heat engine to run a generator to produce HHO to produce more power/efficiency... that's getting a little silly, no?

What sort of torque or power is being generated by the output shaft of a turbo?
