A new type of Solar Heater was designed by three young techies from the North Eastern Regional Institute of Science and Technology. These new heaters contain a parabolic reflector that works in conjunction with the drum that contains water.
Mechanism of the Solar Heater: Sun radiant energy is reflected by the aluminum dish of the solar heater into the drum with a lid at top. The radiant energy of the sun continuously falls on the earth and on a normal sunny day, about 1000 watt of energy per second is received by every square meter by the earth. The radiant energy from sun works on the principle on which the microwave and the electric oven functions, i.e. the energy doesn’t rapidly heat the things but spreads, thus can be used for cooking, grilling, roasting and other purposes.
The parabolic reflector has the capacity to raise the temperature of the water up to 139 degree C the temperature that is sufficient enough to cook cereals and vegetables.
The three techies are the students of mechanical engineering from the institute namely Vikas Gautam, Suman Pao and Juwel Tripura. The newly designed solar heater can be used both for industrial and domestic purposes.
