To heat the house with solar light, but the electricity here at anything
Source:
Today, the country house can be heated not only through coal and gas furnaces but also by solar energy. And we are not talking about the solar panels that generate electricity to power the heaters, and about the so-called solar collectors that focus sunlight at one point and directly heat the water used for heating homes. Thanks to scientists from the Massachusetts Institute of technology, these devices have ceased to lose the accumulated heat, and, therefore, better to heat the premises. All in all, something needed to change one small detail.
Solar collectors composed of a plurality of reflectors, which focus sunlight on the surface of the heat absorbing material. Between the reflectors and the material has a vacuum space with clear glass, which helps to keep the accumulated heat, not preventing sunlight to penetrate inside the device. Unfortunately, part of the accumulated heat gradually evaporates through the glass layer, so manufacturers have been looking for a more waterproof material for warmth retention.
water Heaters will be better than ever
This role is a perfect fit material, researchers from the Massachusetts Institute of technology. At its core, it is ultra-light gel between the particles which is the maximum amount of air and minimum liquid — in science class of such materials is called . Almost not releasing heat to the outside air, a transparent material transmits 95% of sunlight.
Improved the above-mentioned method, the device was tested on the roof of the University and showed good results. When the street was zero air temperature, the solar collector is able to heat the heat absorbing material up to 200 degree Celsius and keep the temperature at the same level.
Sample of a new type of aerogel
In the future this design can become official and people will have the ability to cheaply and safely for themselves and the environment to heat their homes. New device models may be able to cope even with very large rooms.
I Think in the future solar energy will be used everywhere. In addition to space heating, it can be used to provide homes with electricity. Roof with solar panels already offers to install the company is one square meter of tile costs about $ 220.
