The Idaho National Laboratory in collaboration with other institutions is studying ways to harness solar energy at night. The project is just in its infancy and, as usually happens in research, the pieces are developed by different organizations and universities to accommodate the skill. The important thing is that when completed will mark the beginning of the first solar revolution !
The news is that you will take advantage of the sun even when there is no .. How is it possible?
from the beginning: there comes only from the sun light (visible spectrum), but also among other radiation that becomes heat in contact with the ground (especially infrared). Conventional solar panels draw only the visible part of the radiation emitted by the sun, while this new technology makes use of all the radiation that warms the earth. The heat emitted from the ground during the day, is re-released and transmitted by clouds during the night.
This implies restrictions, in fact since there are no clouds in the deserts, these panels would be useless in the Sahara!
order to collect this energy, you are developing nano-antennas of conductive material with theoretical efficiency of over 80%, which, when engineered panels, it would become 46%, in each case more than double than current solar panels (about 20%). Two key benefits are the low cost of producing the antennas, and the fact that you can 'print' on a variety of media, including thin sheets of plastic. This would also make the new panels are extremely versatile, as appropriate in areas not necessarily flat.
This technology could work individually or together with traditional panels, significantly increasing system performance.
The low cost of implementation would bring electricity to those places where there is still, as in the third world or in extremely remote.
