Question

State any two advantages of a box type solar cooker.

Answer 1

Hint:First let us see what a box type solar cooker is:
A Box Solar Cooker is essentially a protected box with a glass cover and a top lid which has a mirror within to reflect daylight into the box when the top is kept open. The internal aspect of the box is painted dark. Up to four dark painted vessels are put inside the container with the food to be cooked.

Complete step by step solution:
Working of a box solar cooker:

Rather than changing sun oriented energy over to electricity, sun based cookers trap light particles, called photons, to produce heat. With the assistance of metal reflectors, which are situated around the oven to augment light, photons go through the oven's clear glass top and strike the inside of the insulated box.

The cooking compartments (with cover) are commonly made of aluminium or tempered steel. These vessels are likewise painted dark on the external surface with the goal that they additionally retain sunlight based radiation directly.

The reflector on the top of the solar based cooker is utilized to centre the sun oriented energy over the glass surface. The mirrors reflect the heat energy in a particular zone and expand the net input energy to the solar based cooker.

Advantages of using a solar cooker:
As a sun powered cooker doesn't burn-through any regular fuel or electrical energy, it spares petroleum derivatives, wood, power and so forth which are generally needed to prepare the food. It doesn't transmit any smoke or smell and subsequently doesn't dirty the climate. There is consequently no way of causing diseases and influencing eyesight or lungs. It doesn't need steady consideration while cooking and henceforth spares time which can be used for some other profitable work.

Note:
Box-type solar cookers and solar cookers are somewhat different. A plane reflector is used in a box type cooker whereas a concave reflector is used in a normal solar cooker.
