A light-emitting diode (LED) (pronounced /ˌɛl.iːˈdiː/[1]) is a semiconductor light source. LEDs are used as indicator lamps in many devices, and are increasingly used for lighting. Introduced as a practical electronic component in 1962,[2] early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet and infrared wavelengths, with very high brightness.

"Displacer-type Stirling Engine Instead of having two pistons, a displacer-type engine has one piston and a displacer. The displacer serves to control when the gas chamber is heated and when it is cooled. This type of Stirling engine is sometimes used in classroom demonstrations. You can even buy a kit to build one yourself!"

Aerotecture International seeks to radically transform the dominant paradigm of energy production and consumption around the globe. Blending the concepts of aerodynamics and architecture, Aeroturbines are wind electric turbines designed to be attached to buildings or integrated into the very form of buildings. With Aeroturbines, buildings and other structures will not only consume electricity, but produce it on-site.

"Every continent on the planet is surrounded by a cleaner, safer, more efficient answer to our energy needs. The power in ocean waves. Ocean Power Technologies (OPT) is a leading renewable energy company specializing in cost-effective, advanced, and environmentally sound offshore wave power technology. The electrical power generated by OPT's technology is key to meeting the energy needs of utilities, independent power producers and the public sector. OPT's PowerBuoy® system extracts the natural energy in ocean waves, and is based on the integration of patented technologies in hydrodynamics, electronics, energy conversion and computer control systems. The PowerBuoy is a "smart" system capable of responding to differing wave conditions. The result is a leading edge, ocean-tested, proprietary system which generates reliable, clean, and environmentally-beneficial electricity."

"Welcome to the website of EmergySystems.org. This site has been developed in response to a demand expressed by the community of scientists, students, and friends for a central location of materials, information and news related to EMERGY. Mission This site is designed to aid in the research and teaching of emergy systems theory. Our mission is to provide a locus for those interested in obtaining information about the theory, concepts and principles of emergy systems and systems ecology. "

"This web page produces a numerical table of sunrise, sunset, daily insolation at top of atmosphere, and sunlight-weighted cosine of the zenith angle at a single specified location. The produced table contains data for a single month, or if a month is not provided, data for a single calendar year. Latitude and longitude must be given in degrees and hundredths of degrees, not degrees and minutes. Default location is the Central Park weather station, New York City. "

"You can use this calculator to obtain the heating value of a given mass or volume of hydrogen or other fuels, or to calculate the mass or volume given a certain heating value. Choose whether you want to convert to heating value or to mass/volume, and then choose the fuel type. Then enter the value you want to convert and its units, and click Convert to initiate the conversion."
