I never heard that free energy machines emitted pollutants. I admit I have much to learn about them. I think I read that one way to do it was to harness the energy already available in the Earth.

Apparently Nikola Telsa designed a free energy machine. I think it looked like some kind of tower. Rockerfeller pulled the financial rug out from under him. I guess the reason for this is because he couldn't make any money from the machine. Perhaps we would lose some of our dependence on government as well.

There was some fascinating speculation that Nikola Telsa, whos free energy machine was operational, decided to create a huge fireworks display with his machine after Rockerfeller pulled the funding from it. If he did, his display went wrong and the energy was misdirected and created a huge explosion in Siberia. This was all off memory and I am not sure if I remember the story correctly.
