Fortunately, there are those who study how to get more energy (renewable) from the Sun, even ... At night. How? Capturing the infrared !
successfully developing a system microantenne wavelength infrared (above 700 nanometers), laboratory tests have verified the possibility of collecting 84% of the photons re-emitted from the ground. A real operating system used on a large scale could rise to 46%. However, an efficiency far greater than that of the best solar panels today
