Guest SuperBurns Posted March 3, 2006 Posted March 3, 2006 Just a question really. It is my understanding that sound is a form of energy. Why can this energy not be harnessed and converted into electricity as a form of natural energy?? Please help, this is really bugging me and i'm sure there must be a really obvious reason. Cheers.
insane_alien Posted March 3, 2006 Posted March 3, 2006 Why can this energy not be harnessed and converted into electricity as a form of natural energy?? it happens in microphones every second of every day. just too little energy in sound and its impractical to build a huge microphone.
ydoaPs Posted March 4, 2006 Posted March 4, 2006 a few years ago, i was at a science fair and someone built an array of lights that were powered by sound.
Illuminati Posted March 4, 2006 Posted March 4, 2006 wow, thats quite impressive, any idea how they did it? Sounds like an interesting project to undertake this summer
ydoaPs Posted March 4, 2006 Posted March 4, 2006 sound is a wave. wave is propagation of energy. go from there. i think they used microphones of some type.
Bluenoise Posted March 4, 2006 Posted March 4, 2006 All speakers and microphones constantly take in sound and covert it to enelectricity. A speaker and a microphone are really the same thing for the most part. Try plugging in a simple speaker into your microphone jack you should be able to record your voice with it. But yeah the amount of energy in sound is insignificant.
