Eliminate the need for electricity for mobile charging.

In the US state of Los Angeles, a team of scientists has devised a system that turns night-out heat into electricity. At this stage only the mobile battery and LED lights can be illuminated with this power. The aforementioned electromagnetic system has been developed by a team led by Dr. Ausoth Raman, a scientist at the University of California Los Angeles. The new method adopted by Dr. Aswatha Raman is called Ready active Sky Cooling. For this, a black disc is placed on the polystyrene box, which is facing towards the sky and has a barrier or block made of aluminum. The black disk cools the ground temperature and the aluminum block warms the cool air at night. This difference makes the thermoelectric difference and it produces a large amount of electricity. Allowing easy charge of an LED bulb or a mobile phone. In a preliminary experiment, one millimeter produces 25 MW of electricity, which is enough to illuminate an LED. But in hot areas, the power output can increase by 20 times. The whole system costs only $ 30 and will be nothing short of a blessing for poor countries.

But its commercial destination is still far away. The above device generates electricity using thermoelectric effect And on the same principle, the conversion of heat from the factory boilers, power plants and exhaust cars into electrical appliances is now common use.
