xanadian: You mean heat?  We haven't, up until recently, discovered a way to harness heat?

Heat when radiated as photons, not heat when in the form of kinetic energy of particles.

Infrared gives an approximation of heat because it's the only wavelength of light that matches the discrete energy changes in electrons from the impacts between particles.

Here's a thought: Jupiter is a gas giant which puts out more energy than it receives from the Sun. It's not big enough to be a brown dwarf, let alone a red dwarf, but locally it has more power than the yellow dwarf that gives us almost all of our energy.

This discovery could lead to big things when we colonize the solar system or even if we never send out anything but drones. I imagine you could put a lot of very light satellites and even space stations in orbit around Jupiter. They could be made of aerogels and powered by infrared and visible light. I don't know exactly what we would do with them, but as the Sun warms and then becomes a red giant, we need to move out. The Earth is at the inner edge of the Goldilocks zone. It won't take a lot to render it unihabitable in a billion years or so. If we survive as a series of species or as cybermen (the Daleks are technically cybernetic men, although they are a terribly stupid design), then we need to move to Mars and eventually to Jupiter's moons or turn asteroids into homes and run-abouts.

This is a step in that direction I imagine. A tiny, very early baby step. But we all had to learn to walk before we could send Saturn rockets into space, and the distance from that to being giant space babies is not dissimilar. Give my regards to Europa, remember me to the Milky Way.
