How to recycle light?


Is there any way to convert light to electricity?
I've heard for solar cells. But they only absorb specific wavelenghts, and I don't know what they do with higher and lower ones? How to convert x-rays, gamma-rays, uv-rays to electricity or heat? Specifically the light from light bulb and fusor/particle accelerator?

For UV and x-rays, you might construct a device that employs the photoelectric effect to make electricity... I suggest you search patents.

A parabolic mirror or magnifying lens to heat eutectic salts, then vaporize water to run turbines. That's how "solar power towers" work. They are much more efficient than photovoltaic cells.

Getting heat is simple, absorb it on a dark, non-reflective surface. Getting usable work out of that heat is harder as efficiency depends on a significant temperature difference. Direct conversion to electricity is also hampered by inherently low efficiency of solar panels. Solving that one will make you rich beyond your wildest dreams, but you're up against pretty intense competition.
