Greetings,
I decided not to call this 'free energy' since that would attract space hippies. Its just daft ideas about where you can scrounge electricity from your everyday environment. Some are better than others obviously but lets see how many we can think of nomatter how silly / pointless they are. Here are a few to start with:
- Solar cells (obvious one). These arent too bad actually. I've got some cheap ones that put out a maximum of 4V @ 100mA (although I havent quite achieved that so far).
- Wind power. Some people are putting small turbines in their gardens these days. My nephew used to work for a company that built them.
- Tap water turbine. They use energy to pump it to our homes, why not take some of that energy back out of it (and dont blame me if it catches on and there are unexpected drought warnings)
- The phone line. Possibly illegal and definitely risky. A sufficiently low impedance on your phone line will at best raise alrms and at worst cause damage but if youve got the skills and the cunning theres 50V up for grabs there.
- Radio waves. Not really worth the effort for the pathetic amount of energy youd get but still valid.
- Radioactive decay (as mentioned in another topic). I'm not touching this one with a barge pole but if you feel like dimly lighting an LED for a few years grab yourself a couple of tons of funky stuff
- Natural kinetic energy. Who says you need a bike and some excersise - simply strap a bunch of magnets and copper coils all over your body and say its the latest fashion accessory
- Piezo crystals. If you put enough of these in a high vibration area like a road or rail bridge (or even a fault line) you might get something useful. And it will keep on giving right till the end even in that controlled explosion when the bomb squad dispose of the suspicious device under the bridge (I heard a funny story of this happening to a £1500 bat detector which had been left to record)
