I have been discussing free energy with a new friend. His interest seems to be with Tesla and the idea that is possible to create a small devise that everyone can own, and use for getting free energy out of the air.
I am curious about the different wave lengths of sun light, as not all of the result in heat, and none of the result in heat without oxygen. I am leaping there. I have not read this, but do know out space is cold, and high altitudes are cooler than low altitudes where there is more oxygen. However, evidently there is more heat on the side of the moon that gets light than the dark side and I don't think there is oxygen on the moon? Hum, I have to look into this. Oh Good grief, now I have a whole area to research.

What is the temperature on all the different plants, and what controls that?
So how does a tornado generate energy. Could this be the vacuum energy that some are studying? Energy involves the exchange of Ions, and lightening, waterfalls and ocean waves release ions, but I have zone understanding of vacuum energy. Obviously a tornado has kinetic energy, but how would this be converted to electrical energy?
By the way, if anyone cares, some branches of Occupy are interested in the research for free energy. Imagine our technology and everyone around the world being able to use it, because they can have free electricity by using a small devise. Everyone can live off the grid and avoid the fossil fuel sources of energy that are used today.
