Optical fibers can also be used for daylighting. A solar lighting system based on plastic optical fibers was in development at Oak Ridge National Laboratory in 2004. [13] [14] The system was installed at the American Museum of Science and Energy, Tennessee, USA, in 2005, [15] and brought to market the same year by the company Sunlight Direct.
A garden solar lamp A child in Zambia studying by the light of a lamp charged by solar power during the day. A solar lamp, also known as a solar light or solar lantern, is a lighting system composed of an LED lamp, solar panels, battery, charge controller and there may also be an inverter.
In 2015, the company announced it would supply batteries for a Hawaii microgrid to serve as backup for a 176-kilowatt solar panel array that would store 1,000 kilowatt-hours of electricity. [11] In April 2015 they announced they have been cradle-to-cradle design certified. [12] [13] It was also reported they were reducing headcount. [14]
Light pillars in London, Ontario, Canada Sun pillar in San Francisco, California. A light pillar or ice pillar is an atmospheric optical phenomenon in which a vertical beam of light appears to extend above and/or below a light source.
The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower.
Solar road stud. Solar road studs are flashing solar cell powered LED low-maintenance lighting devices that delineate road edges and centrelines. Embedded in the road surface, they are an electronic improvement on the traditional cat's eyes [1] and raised pavement marker in that they may give drivers a larger reaction window.
Solar farms are more cost effective in West Texas, where insolation levels are greater. [29] The US uses about 100 quadrillion British thermal units (29,000 TWh ) of energy each year. [ 30 ] This number is expected to be reduced by 50% by 2050, due to efficiency increases. [ 31 ]
The Sun is a rotating sphere of plasma at the center of the Solar System. It lacks a solid or liquid surface, so the interface separating its interior and its exterior is usually defined as the boundary where plasma becomes opaque to visible light, the photosphere.
