Ultimate Power Builders

"Ultimate Power Builders" defies all four basic elements (earth, air, heat, and water) to engineer big, ambitious and environmentally-friendly projects that will shape the Earth's landscape for future generations, while providing unlimited sources of energy. Watch as the construction of one mega-structure after another evolves, whether it's a carbon neutral city in the Middle East; a skyscraper in China which produces its own power and water; an energy plant that harnesses the power of the atom or a geothermal station that drills deep within the Earth to tap the extreme heat down below to operate. Ultimate Power Builders reveals how far technology will go to secure a sustainable existence for all. (Source: http://www.planetgreen.discovery.com/)
