Significance Renewable energy can be generated whenever heat flows from a hotter to a colder body. One such flow is from the warm surface of Earth to cold outer space, via infrared thermal radiation.
If you''re harvesting energy from infrared emissions, the voltage will be relatively low," explains Byrnes. "That means it''s very difficult to create an infrared diode that will work well." Engineers and physicists, including Byrnes, are already considering new types of diodes that can handle lower voltages, such as tunnel diodes and
For the latter, we propose using an infrared-frequency rectifying antenna, and we discuss its operating principles, efficiency limits, system design considerations, and possible technological implementations.

INTRODUCTION. Thermal comfort, heating ventilation and air conditioning (HVAC) systems requiring energy supply are widely used in space cooling, resulting in excessive consumption of fossil fuels and significant greenhouse gas emissions such as CO 2 [].Massive CO 2 and other greenhouse gas emissions have resulted in the rise of global temperature and
Man has shown considerable ingenuity in seeking out renewable energy – chasing after wind, tides, biomass, sunshine and more. But there is one source that we have not yet tapped – the 10 17 W of infrared

2.1. Isolated IR Antenna. In recent years, the use of nanoantennas has gained a great interest for solar energy harvesting [10, 15, 18, 29].These antennas couple electromagnetic radiation at very high frequencies, THz, and IR regimes in the same way that RF antennas do at the corresponding wavelengths.

Cambridge, Mass. – March 3, 2014 – When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night?A battery, perhaps, or an old diesel generator? Perhaps something strange and new. Physicists at the Harvard School of Engineering and Applied Sciences (SEAS) envision a device that would harvest energy from
It is possible to harvest energy from Earth''s thermal infrared emission into outer space. We calculate the thermodynamic limit for the amount of power available, and as a case study, we plot how this limit varies daily and seasonally in a location in Oklahoma.
