Was just wondering if there are any renewable energy sources not being used effectively...We all know that solar, wind, tidal energy etc are being used to various extents...Sitting at the MCity FC during lunch time, there is a seemingly endless buzzz..100s of people talking, laughing etc...their sound waves being added to produce a sound like the one you get at theh beach...So what if we could convert this to energy?
Use a microphone...convert these sounds to electric signal...rectify that to get dc and use it to charge ur battery...
Might be this dc will be of very low value...but what ever you get free is good :)
Did some research on net regarding this...seems that people are thinking and researching about this....
Noise is one thing which is there all around us..Hopefully someone will change the proverb "Silence is golden" :)
