Solar Wind Energy Tower, Inc. received approval last Wednesday from San Luis, Arizona to build a $1.5 billion project that would use ambient desert air to create a draft and generate electricity in a concrete tower.  A picture of how the project will work can be seen above. Once finished, the 2,250-foot tower would be the tallest structure in North America.  The Solar Wind Downdraft Tower project would be able to generate power at an average rate of 435 megawatt-hours annually.  The tower would be able to generate close to 1,200 megawatt-hours during July and August due to the higher summer temperatures.

The Blackfriars Railway Bridge in London, England is now the largest-solar powered bridge in the world.  Network Rail, the company in charge of London’s rail system, unveiled the bridge at a ribbon cutting ceremony last Wednesday.  The roof of the new bridge is covered with 4,400 photovoltaic panels.  The panels will supply half of the energy needed to run London Blackfriars station, and they will help to reduce the station’s carbon emissions by 511 tons per year.  By comparison the world’s only other solar bridge, the Kurilpa Bridge in Brisbane, Australia, will save 38 tons of carbon emissions each year.
