Introduction: Harnessing Sound Power
Everyone is talking about using solar panels and wind turbines to Go Green however those are far from the only sources of renewable energy; one that is almost never spoken of is sound.
Although it does take a fair amount of noise to generate a descent amount of electricity, if you think about it, say you were to harness all the noise from a football game or the hustel and bustel of a large city, by the end of the day you have a lot of power energy. And, while it is of course far from the solution to the plethora of climate problems that faces us--being as impractical and inefficient as it is--the notion of converting sound into electricity is nevertheless in my mind a very neat and fun concept to which very little attention is given.
The things you will need:
1 volt meter
1 speaker (the bigger the better)
Step 1: Wiring the Speakers
The whole process it quite simple. The first step is to attach wires to your speaker. Your speaker may already have wires attached and if that is the case go right onto the next step.
Step 2: Hooking Up the Speaker
The next thing to do is to connect the your positive and negative wires on the speaker to the volt meter contacts and switch it on.
Step 3: More
To increase its output you can place the speaker up against a speaker playing some music or if you happened to own a jet, you could strap it onto the engine and make some serious electricity!
