Two MIT and Chile researchers develop a system which can cool things down up to thirteen degree Celsius without consuming any power, even after keeping it under the blazing sun.
Though it may seem like magic, the device works on the theory of radioactive cooling and is not equipped with any moving parts. It does not let the device heat up by blocking the sunlight and radiates the infrared light, which goes out in space, thus cooling the device at the ambient air temperature.
The key material used to make the process successful is aerogel. It is a lightweight material that feels soft but is capable of reflecting the sunlight and restrict it from penetration. However, the infrared rays radiated by it, carry heat and pass it out to the outer space.

Reportedly, the method can have varied usages in our day to day life. The newly developed system is capable of keeping the fruits and vegetables fresh and prevent them from spoiling.
Moreover, the radioactive method of cooling can prove to incur a much lower cost than the other modern techniques. This is the reason that many scientists are taking it into consideration and proceeding towards further research procedures.
