How to collect the energy from the heat of the environment

  1. May 4, 2009 #1
    It seems like the outside air has a considerable amount of energy in it, at around 298K. Is there any way to collect this energy without expending more energy? It seems like this would be possible.

    Is there anyway to cool this other than putting a cold object in the air? What would be the fastest way. What would be the most efficient way? What would get the surrounding air to the lowest temperature?

    You can use a heat pump or air conditioner to move heat from one place to another, if that is what you mean. If you are talking about using heat from the environment to generate electricity, no, that isn't possible - heat has to be able to flow from a hot reservoir to a cold reservoir to be able to be harnessed for mechanical/electrical power.
