Isaac Solar Ice Maker Solar Icemaker Up to 1000 pounds of ice per day! Low cost and reliable source of ice for situations requiring 25 to 1000 pounds of ice per day (12-450kg). "Isaac" is the acronym for Intermittent Solar Ammonia Absorption Cycle. Ammonia absorption refrigeration technology was developed in the 19th century and is still used in industrial applications. Energy Concepts has adopted this technology to a machine which uses the sun as the only energy output. The particular advances

Solar water disinfection Solar water disinfection is a type of water purification system that uses solar energy in order to make contaminated water safe to drink. This is done by eliminating contagious biological organisms such as bacteria‚ viruses‚ protozoa and worms. This process can only be taken place on biological agents non-biological agents such as toxic chemicals or heavy metals disinfection may not make all kinds of water safe to drink. Therefore additional steps away from disinfection

Proper understanding of each of these discoveries and theories is important when learning about our universe. Planetary Accretion Planetary accretion has two main theories on how the planets in our solar system were formed. The first of the two is the Solar Nebular Disk Model; this is where our Solar System’s planets started out as small pieces and started to collide together‚ uniting into bigger pieces and this kept happening until they became planetesimals. Once they were planetesimals‚ they crashed

Introduction "A "light bulb" now exists that does not use any conventional energy. Introducing the Solar Bottle Bulb -- an alternative source of daylight powered by the sun. It is made from an old soda bottle. By filling it with water and sealing it into the roof‚ the water refracts the sun’s rays and provides about 55 watts of light to a darkened room. This was invented in 2006 by students at the Massachusetts Institute of Technology (MIT). It can be built and installed in less than 1 hour

first modern solar cell In 1954‚ the first modern silicon cells raised by Bell Labs‚ then it shown at the National Academic of Science meeting. Moreover‚ this kind of cell can make 6 percent efficiency. Then‚ the New York Time come up with that the cell would lead to a source of “Limitless energy of the sun”. In 1955‚ the Western Electric created very significant solar cell technologies. The technology start to use in makes solar cells. In 1957‚ the AT&T telecom company used the “solar battery”
