Fellows Thermoacoustic Cycle (TAC) Generator

Lee Fellows' Thermoacoustic Cycle (TAC) Generator uses heat to amplify acoustic waves (sound waves) in a high pressure gas. These amplified acoustic oscillations drive a unique kind of generator and produce electric power. The system can allegedly be built at a very low cost.

The TAC is designed to produce power from almost any source of heat energy. When powered by solar radiation or waste exhaust heat from other systems, the TAC has no polluting gaseous emissions. It can be configured for use with a wide variety of combustible fuels, and burn them efficiently in a low-pressure combustor with very low emissions and a controllable heat signature. It can be configured to burn any combustible fuel, including methane, natural gas, LPG, gasoline, alcohol and fuel oil.

For high power they need to replace the piezoelectric converter on the TAC with a proper magnetic generator actually able to produce kilo-watts of power - significantly more than most solar panels. A sealed for life (low maintenance) prototype that can simply be attached to someone's equipment is needed. Get its picture into a few magazines.

So it is a modified sterling engine, combined with a peasieoelectric generator? I love this idea. Keep up the good work. The overall design looks like it needs to be reengineered but I cant seem to put my finger on the main problem maybe its the placement of the pesieoelectric martial.

I read many books, and 70%? No way.

Name me one book and 1 product that does it.

If you can not, stop cheating.

nice 5 stars for ya bro.

[Subspace4d]

no they can be more efficient to 70% man. read the books. Really they are the best.

[SWINGREGORY]

great

[electrique527]

Problem with these engines / converters is the very low efficiency. They are simply no match for the existing stirling engines, even though those are more complex.

Also, your presentation is incorrect in places, very one sided, and almost misleading in other parts.

The technology is good, but not as rosy as you make it here.

This is a thermoacoustic stirling engine yes?

It seems very similar to recent thermoacoustic designs.
