The world’s largest wind turbine is now the Enercon E-126. This turbine has a rotor diameter of 126 meters (413 feet). The E-126 is a more sophisticated version of the E-112, formerly the world’s largest wind turbine and rated at 6 megawatts. This new turbine is officially rated at 6 megawatts too, but will most… [Continue Reading]
Here’s an example of daylighting at the Hong Kong Science Park. Notice that the light is filtered through translucent skylights and clerestories in a central atrium, thus reducing glare and overheating. The top of the building has shades, see them after the jump:
Science Daily reports that British scientists have developed a “biofuel cell” that generates electricity from air spike with small amounts of hydrogen. These cells are an inexpensive, renewable alternative to “fuel cells” that have been closely associated with the “hydrogen economy”. At a recent meeting of the American Chemical Society, Fraser Armstrong, described how his… [Continue Reading]
