Mind you I ask how do you get free electricity?
Most people get it as part of their lease or rental contract, but you need to be careful since many of those free electricity locations have stipulations that the utility not be used for commercial purposes.
There are Free electricity, virtually. I know such setups. There are such legit setups.
In historic years even people patented free energy making machines in US.
Later, after such a persons funeral, the secret behind it was found,
It was terrible he used many forced air/pumps to crease such Perpetual Motion Machines. All where hidden in his floors and walls.
Sorry, I was not talking about such a Perpetual Motion Machine.
But some initial investments and if you have an environmental support like a water fall, a virtually free energy source can be created.
Along with that solar and wind can be added to make a hybrid system. But all includes some initial investments and maintenance costs. But its worth the money.
Inshort virtually we can generate free electricity at a small "cost".
