The MagLev Wind Turbine is a big step forward in the world of wind power. By using magnetism to levitate the blades friction is eliminated and more power can be produced without any additional power expense (since the magnetics require no energy to run). The MagLev has a low threshold velocity for producing energy, could theoretically survive for centuries and can power up to 750,000 homes. Though the initial investment involved hundreds of millions of dollars the payoff is potentially huge.
The Lighthouse skyscraper is a 1000-foot-tall office skyscraper that is designed to use about half the water and energy of a typical high-rise building. The tower design employs solar energy collection and wind farming techniques coupled with strategies to reduce the use of and improve recovery of energy and water within the building. If/when built, this building will be a kind of working prototype for future green design in massive urban construction
The most impressive feature of the new Bahrain World Trade Centeris, no doubt, the three massive wind turbines situated between the two towers comprising the main building. Each of these 80-foot turbines projects from a bridge between towers. The shape of the towers themselves channels and accelerates air moving between them which will help the building generate even more power. It is by far the largest wind-powered design incorporated into a massive building project to date.
