Tallest solar tower in the world being erected

Shooting 787 feet into the skies of Israel will stand one of the world's largest solar towers. As you can see from the photo above, construction is well underway.
Wondering what's surrounding the tower? No, that's not a high-tech crop circle. Those are 50,000 mirrors – spanning the length of 665 football fields – which will help boost the output of the tower.
When completed in 2018, the renewable energy it produces will be able to power 130,000 homes in the area. It will support Israel's commitment to reach 10% of the country's electricity production from renewable sources by 2020.
The tower, known as the Ashalim solar project, is truly an international effort. French engineering firm Alstom is overseeing the construction using parts from California-based BrightSource Energy and Boston-based General Electric.
