Physicists Harvest Infrared Light Into Energy

Lumistar-Blog-Infrared Earth

Possibly as a future add-on to solar panels for harvesting energy at night, physicists at Harvard University have found a way to capture thermal infrared energy that escapes every night into space by the very act of allowing it to escape.  By using the principal of hot and cold differential to harness electrons into voltaic current, similar to how radioisotope thermoelectric nuclear batteries are used on artificial satellites, the thermal power generator would capture the infrared photonic energy with the use of a “hot” plate, as warm as the Earth, with a “cold” plate on top made from a material that would quickly radiate the thermal infrared electromagnetic photonic wavelengths back to the cold vacuum of space.  During a pilot study in Lamont, Oklahoma, the researchers have calculated that the heat difference between the plates could generate a few watts per square meter, day and night. This natural radiation happens every night with some of the infrared energy being trapped by our atmosphere to keep the planet from being as cold as space, thus named the greenhouse effect. With the sun bombarding the Earth with infrared heat that escapes every day and night continuously back to space this is clean energy that can eventually be used. Scientists hope to create a working model and become further efficient producing additional watts by using nanotechnology making efficiency possible.

  7. Hello there! This is kind of off topic but I need some advice from an established blog. Is it very hard to set up your own blog? I’m not very technical but I can figure things out pretty quick. I’m thinking about setting up my own but I’m not sure where to begin. Do you have any tips or suggestions? With thanks.
