Most of our energy sources are quite small. It is true that energy can be transferred from one form to another but most of the time, after uses we can we reuse them. So they become wasted. As an example, we can use the Thermal power plant to burn coal and get heat energy which is transformed into electricity. But after we use it, they can be reused. And coal is quite Limited.
So we are running out of energy sources very soon. In the early 80s’, scientist believed that if we don’t find any other energy resources that can be transformed into many forms and its quantity can be compared to almost infinity. We won’t have any more energy sources. So many scientists were trying to find a new energy source to solve this problem. Among them, Alexandre Edmond Becquerel was the first one who discovered solar energy.
While working with an electrode, he saw that when shining sunlight hit on the dead electrode, a small amount of movement was shown in ammeter. He claimed that it was for the photovoltaic effect which can transform into electricity. But he didn’t have any idea how he could transform solar energy into electricity in a large amount.
Many scientists that time tried but failed. almost a hundred years later Russell Ohl successfully made a solar energy cell. Though it was too small, it could at least work on a small bulb. After this, a new dimension opened for the scientist. They tried to use solar energy in as many sectors as they could.
Frank Shuman who was the first man who invented the use of solar energy. He made a small size full power steam motor that can be run by solar energy. Though in 1897 he used a mirror to confine light and transform into a massive heat producer and then he used it to heat water. But after solar energy was discovered he transformed his old plan with a new one. He even made the world first Solar Power Thermal station in Egypt. We can tell him the pioneer of latest solar energy based invention.
The main demand of the first moving world is electricity. But as we have used most of the energy sources, we had to look for a new one which will be able to fulfill our needs for a very long time. Solar energy is the one that we found. it has already become One of the leading current product function since 2003.
In polar or desert regions, Producing and supplying electricity is quite a hard job. especially in polar regions keeping the home heated is very much needed as when the sunset the temperature decreases almost 20 degrees. In cold areas, they use mirrors to capture the heat and inside the house, they create a greenhouse effect which doesn’t let the heat get out of the house. In the heated area, the rivers process of this is made. in the morning they use solar energy to transform it into electricity. but at the night when the temperature gets too low, they use the greenhouse effect to maintain the temperature.
Molten Salt Process
If we use solar power directly to make electricity, we can get only one way of usage. but if we are able to transform it into heat and then use Thermal power plants, we will get more electricity. So in 2002, the scientist was successfully able to make a mixture that good contain solar heat as a heated tank. India was able to make the largest molten salt process. that’s why they were able to increase production rate two times more than before
