Solar-powered household lighting can replace other light sources like candles or kerosene lamps. Solar lamps have a lower operating cost than kerosene lamps because renewable energy from the sun is free, unlike fuel. In addition, solar lamps produce no indoor air pollution unlike kerosene lamps. However, solar lamps generally have a higher ...
Solar lighting systems capture light from the sun and conduct it towards a room using optical fibers. They use rooftop collectors, large mirrored dishes, that track the sun. The collectors adjust to aim the sunlight onto 127 optical fibers which are conducted into a single chord. The optical fibers are flexible and can be connected into hybrid ...
The Solar Bottle Bulb, as it has also been called, [7] is installed in the roof of homes with the purpose of refracting sunlight in order to light up a room. The project's innovation lies in its utilization of cheap, durable and readily available materials to produce high quality natural lighting enabling the urban poor to have access to an ...
High-pressure sodium lamps are quite efficient—about 100 lumens per watt, when measured for photopic lighting conditions. Some higher-power lamps (e.g. 600 watt) have efficacies of about 150 lumens per watt. Since the high-pressure sodium arc is extremely chemically reactive, the arc tube is typically made of translucent aluminum oxide.
Most of van Aubel's work involves incorporating solar cells into furniture, windows, and other objects. [3] She has also designed a cover to maximize the surface area and thus the yield of a solar panel. [4] Her solar-powered table charger, Current Table, was included in the 2015 Design Museum Designs of the Year exhibition in London.
The Far Rockaway Depot and the John F. Kennedy Depot (or JFK Depot) are garages that were operated by Green Bus Lines until January 9, 2006, [4] when MTA Bus took over and started operating the old company's bus routes.
