Solar ? Wind ? Hand/Foot generator

Solar or salt driven batteries is all that comes to mind. What are you trying to do?

take an extention cord and tie into the neighbors electricity J/K ....

There's lots of people who use solar setups for basic energy needs but be ready to drop a couple thousand dollars to make solar panels big enough to power the basic electrical in your home. Often using solar means curving your use signifigantly and using gas for heating and cooking

One might want to include the power of currents in rivers, streams and the Oceans of the world also.

I have worked with renewables for years, really there is no such thing as free energy. It costs a lot to have it set up and it takes an insane amount of time for it to pay off.

@derrick has the only quick method however it's not exactly free for your neighbour

I was thinking magnets and other stuff like that There is lots of free energy out there the problem is that its cold so its not really ussable But its not hard to convert to good usable power when you run it into a cap or a bank of caps then when the cap is full discharge it into your batts

Another aspect is recovering waisted energy like the power lost as heat in the heat sinks I have been playing with a thurmal ellectric device i got from a colan ellectric cooler i found on the road A thurmal elecric device will convurt power to heat/cold or turn heat/into power Its really cool i hooked it to a little motor then placed the device in my hand and the motor would run The way it works is from the difrence in the temprature of both sides of the device the more the diff the more power you get If we add that to the heat sinks and feed that to a cap we can recover some of that wasted power
