Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.

This week Inhabitat saw renewable energy projects blast off around the world as Kenya announced the construction of the largest wind farm in Africa and a team of Georgia Tech researchers developed a heart-powered nanobattery that can charge your gadgets on the go. We also learned that the mixture of saltwater and fresh water in estuaries could provide for 13% of the world's power needs, and we took an in-depth look at a cryogenic energy system that produces electricity from liquefied air. Finally, we showcased photographer Mitch Epstein's haunting photos of "American Power" which recently won the Prix Pictet prize.

It was also an epic week for architecture as the Pritzker Prize - the world's highest architecture honor - was awarded to Portuguese architect Eduardo Souto de Moura. We also saw a high-tech solar skyscraper with a mind-bending wavy facade rise in Seoul, and we shared 15 visions for skyscrapers of the future -- from vertical farms to shipping container towers and oil rig cities.

Finally, this week we saw a bright future dawn for green transportation as a team of students unveiled a hyper-modified electric Audi TT that is powered by solar energy. We also learned that the European Union is considering banning gas cars by 2050, and we took a look at Microsoft's new database that tells you the cheapest place to charge your EV. Last but not least, we brought you a 10-seater pedal-powered party bike, and we showcased a stylish LED-lit jacket designed to keep cyclists safe at night.
