but how can you just blow off an energy source that is consitantly made with everysingle type of engine.
even if it only get a little energy it could make a lot of things more efficient.
even if it gave you 2 extra mpg i mean that's a lot.
Yes, that
is a lot - and sound energy can't do that for you! Sound energy is
much, much, much weaker than that. Lemme back up a bit:
Converting sound energy to electrical energy is not a new concept. That's what a microphone does. And there
are systems out there, such as the Navy's sound powered phones, that use the energy generated by the microphone to power the device. But the amount of energy we're talking about here is miniscule.
If you could use the enclosure of a gas turbine enegine to capture the sound (in a way, it does already...) and convert it directly to power, you'd be able to generate a few extra watts for a plant that already generates megawatts.
For other devices, it isn't even possible to do that - you can't improve the fuel economy of your car this way because you can't caputure the sound without enclosing the car in a coccoon. Sound energy radiates in all directions.
A somewhat related concept that would be more workable would be to use piezoelectric shocks or engine mounts in your car to generate electricity. These might generate enough electricity to run the cabin LED lights, but that's it: a few watts.
