There is a new study on a whole different way to get cheap, environmentally safe energy. In Israel, they found that if you make a huge tunnel, and make the hot air at the top turn cold, the cold air would drop very fast and power some turbines to make energy. This machine would work in hot, dry climates and would be the cheapest form of energy out there. They are still waiting for funding, but let's hope they can get a few up and running soon.
