Another way to recycle heat that is being explored is to capture infrared with photovoltaic cells similar to those used in solar panels.

While scientists know the cause of the aurora, exactly how it affects earth is still in question. Though infrared cameras have captured solar storms, the aurora remains a mystery.
NASA supercomputer simulations released September 23 suggest what our solar system may look like to an alien using infrared technology now—and millions of years ago.
