Inhabitat's Week in Green: the world's largest laser fired, icy roof tiles admired, faucet lamps inspired

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!
