These inverted solar panels can generate power from almost any heat source
Generating renewable power has got to be one of the coolest things we do as a species. Finding ways to draw endless power from what's already going on naturally around us is the biggest of big-brain stuff. Solar is one of the more common ways of generating renewable power, especially for regular consumers. Many residential houses have solar panels of their own, and you can even buy panels for camping and other activities relatively cheap nowadays.
Living in Australia, I'm endlessly in awe of my own solar panels and gleefully watch them diminish and sometimes completely obliterate my power bill in summer. Still, solar power has come under criticism by some, and one of the complaints I often hear is that it doesn't work at night. It can be a moot point with batteries and other renewable sources working in tandem, but is still technically true.
Well, I'd like to introduce you all to these weird solar panels, which actually do work at night.
As told by New Atlas, a team at the University of New South Wales has been able to generate power from what is essentially an inverted solar cell, at night. The way it works is by using the infrared light that the Earth radiates at night, after a hard day of absorbing all that sweet, sweet solar energy.

The researchers used a device called a thermoradiative diode, which absorbs the energy radiating out of a heat source, like the Earth, to somewhere colder, like the cool night air, and turns the difference between the two into potential electricity.
In theory, these inverted solar panels can be used to gather energy from basically anything that emits light. Any time heat
