Solar energy comes in several forms. The majority of us are most familiar with solar cells, but you will find truly several different techniques to produce and store solar energy. Here are several of those techniques:
Solar Cells – The majority of us have observed solar cells made use of on calculators with LCDs. But they have also been made use of in several other techniques. Solar cells use semiconductors (oftentimes, silicon) to create electricity, directly from the sunlight.
Solar Fibers – This can be also a photovoltaic device (like the solar cells), only it doesn’t use silicon. Rather, it has a solar tape which is created with titanium dioxide. This tape could truly be combined with creating materials or even clothing.
Solar Pond – A solar pond is created of 3 layers: the leading layer as low salt content. The middle layer is an insulating layer with salt, and it prevents natural convection within the water (which would usually cause heat exchange). The bottom layer as a really high salt content, and this layer can method high temperatures. Due to the fact of all the densities in salt of the different layers, you will find no convection currents (which usually transfer heat to the surface and then the air). The heat that gets trapped within the bottom layer can be made use of to heat buildings, create electricity, or in industrial processes.
Solar Chemical – There are actually many different solar energy processes that absorb sunlight in a chemical reaction to produce that solar energy. A lot more research is needed on solar chemical energy just before we are able to apply it practically. Considerably of this research is on photoelectrolysis of water.
Solar Updraft Tower – This can be a type of solar energy plant in which air passes below an agricultural glass house, gets heated by the sun, and is then channel up toward a convection tower. It truly is made use of to drive turbines which create electricity.
Energy Tower – This tower utilizes water, unfortunately, but it is also a great design and works in a comparable method to the solar updraft tower. Water is sprayed in the leading of the water. The water evaporates which causes a downdraft by cooling the air. This coolness increases the density of the air and then drives turbines which are in the bottom of the tower.
These are just several techniques in which solar energy has been and is getting designed. Perhaps one of the most widespread household type of solar energy is that designed by solar cells. Nonetheless, these other varieties are incredibly promising and unquestionably have their location.
