Solar energy comes in a lot of forms. The majority of us are most familiar with solar cells, but you can find actually a lot of different techniques to build and store solar energy. Here are a few of those techniques:
Solar Cells – Most of us have observed solar cells utilised on calculators with LCDs. But they’ve also been utilised in a lot of other techniques. Solar cells use semiconductors (oftentimes, silicon) to generate electricity, directly from the sunlight.
Solar Fibers – This is also a photovoltaic device (like the solar cells), only it will not use silicon. Rather, it has a solar tape which is produced with titanium dioxide. This tape could actually be combined with constructing materials or even clothing.
Solar Pond – A solar pond is produced of 3 layers: the top layer as low salt content. The middle layer is an insulating layer with salt, and it prevents natural convection inside the water (which would ordinarily trigger heat exchange). The bottom layer as an extremely high salt content, and this layer can strategy high temperatures. Simply because of all of the densities in salt of the different layers, you can find no convection currents (which ordinarily transfer heat towards the surface after which the air). The heat that gets trapped inside the bottom layer is usually utilised to heat buildings, generate electricity, or in industrial processes.
Solar Chemical – There are actually many different solar energy processes that absorb sunlight in a chemical reaction to build that solar energy. Additional study is necessary on solar chemical energy prior to we are able to apply it practically. Significantly of this study is on photoelectrolysis of water.
Solar Updraft Tower – This is a form of solar energy plant in which air passes under an agricultural glass home, gets heated by the sun, and is then channel up toward a convection tower. It is utilised to drive turbines which generate electricity.
Power Tower – This tower utilizes water, however, but it is also a good style and works in a comparable technique to the solar updraft tower. Water is sprayed in the top of the water. The water evaporates which causes a downdraft by cooling the air. This coolness increases the density of the air after which drives turbines which are in the bottom of the tower.
These are just a few techniques in which solar energy has been and is being designed. Perhaps the most prevalent household form of solar energy is that designed by solar cells. Nonetheless, these other varieties are pretty promising and definitely have their location.
