Generating Light From Darkness

New, Transformative Device to Generate Power from Night Sky Source:   UCLA Renewable and Complements Solar Power This new, inexpensive thermoelectric device may be transformative in energy generation.  It harvests the coldness of space during the night to generate electricity - enough right now to power a LED light at nighttime, but the inventors say it's very scalable.  The device is a significant new innovation from engineers at UCLA and Stanford University.  The gadget works at night when solar systems don't.  The inventors say it's a new approach to power generation when power at night is needed.  It complements solar power that doesn't work at night, giving a 24/7 approach to green, renewable energy. Phenomenon Like Frost Formation The device takes advantage of radiative cooling, the process by which frost forms on grass during above freezing temperatures at night.  The sky facing surface of the technology passes heat to the atmosphere as thermal radiat
