A 2,250-Foot Tall Tower in Arizona Will Usher in the Future of Wind Energy | Motherboard: "Wind and solar energy only provide us with power as nature allows, but solar-wind hybrid towers could soon overcome this limitation. The company Solar Wind Energy, based in Maryland, has now received the necessary startup capital for the construction of a 2,250-foot-high tower in Arizona, which would be the tallest freestanding structure in the US."

Now researchers at Empa in Switzerland have developed a new type of SMA that could allow the material to find applications in the building and construction industries."
