Solar home electric generators are becoming increasingly popular because sustainability and the use of renewable resources is now entering mainstream understanding. Whereas in the past, harnessing the power of the sun for electrical generation may have seemed like the domain of the hippy population, in the New Millennium, it’s become a movement for many more people.
In 1892, in Boise, ID, the energy from local hot springs was piped into buildings for the first time. By 1900, 200 homes and 40 businesses were powered this way.
In 1922, John D. Grant drilled well geysers in Arkansas, creating the United States’ first geothermal power plant. Grant used steam from the first well to build a second well, and, several wells later, the operation produced 250 kilowatts, enough electricity to light the local buildings and streets.
Ultra violet water filter systems are used to purify water in order to remove bacteria and make the water drinkable. UV offers a popular filtration system because not only does it remove bacteria it does so without relying on heat or chemicals, which could change the water. UV water filtration systems work by using ultraviolet radiation. This radiation changes the property of living matter. There are several types of UV filters which include long-wave, middle-wave, and short-wave.
Long and middle wave ultra violet light occurs in sunlight and does not have any ability to change the composition of water by removing germs from it. Short-wave UV light is what is used when you hear ultra violet water filter systems.
