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 scientists took a step towards unlocking the holy grail of alternative energy as they unleashed a one megajoule test blast from the world's largest laser. We were also excited to see the DOI give the green light for the first solar-thermal power tower in the United States, and we saw big things brewing beneath West Virginia as a project funded by Google discovered massive geothermal vents that could double the state's energy generation capacity. Not to be outdone, Oregon announced plans for a 845 megawatt wind farm that stands to be the largest in the world.

We also watched the world of architecture heat up - literally - as Soltech unveiled a set of glimmering glass roof tiles that can capture solar energy to heat your home. We also checked in on the development of Masdar, the world's first carbon neutral zero-waste city, and we were shocked and appalled by the recently completed largest and most expensive house in the world.

In other news, this week we showcased a dazzling array of energy-efficient lights - from an amazing animated LED pillar to a set of liquid lights made from recycled faucets to a chandelier decked out with luminous dandelions. We also kicked up our heels for a vending machine that dispenses biodegradable shoes and we saw a set of ghetto-fabulous boom boxes made from old suitcases hit the streets. Finally, we rounded up a gaggle of our favorite smartphone games that are perfect for keeping kids entertained!
