An Air Condition for the Planet: How Could It Work?

All power plants create waste heat that contributes to global warming. At the moment, the contribution is fairly small, but if mankind flourishes it is bound to increase and eventually it will become a problem. The only thing we an do about it is to build an air condition for the planet. Scientists have come up with some ideas how to address the problem that I hope you will find entertaining.
