IKAROS gets first burst of solar propulsion, wants more
Photons, man, it's all about the photons. Japan's solar sail-equipped IKAROS probe has recorded its first propulsion derived from the force of sunlight rays hitting its tender surface. The force generated is a truly minuscule 1.12 millinewtons, but that can go a long way (literally) in a frictionless environment like space. The kite's sails also soak up Sol's emitted light to generate electricity, making the most out of the one resource available to it. So now that we've figured out how to do all that, shall we get started on colonizing Mars or what?
Inhabitat's Week in Green: a US team wins the Solar Decathlon!
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us. This week Inhabitat reported live from the scene of the Solar Decathlon in Madrid as 17 stunning solar-powered houses competed for the title of the world's most energy-efficient prefabricated house. The winner was just announced this evening and we're thrilled to see that an American team won: Virginia Tech's shape-shifting Lumenhaus. Considering that German teams have won the American Solar Decathlon for three years running now, we're really proud of the Virginia Tech team for their big win! We're also happy to see that several of our favorite solar houses from the show made it to the top ranks, including Germany's elegant IKAROS house, the ultra-efficient Armadillo Box, and Finland's beautiful wooden Luukku house. We also watched sustainable transportation soar to new heights this week as the world's first solar-powered blimp prepares to fly across the English Channel. Not to be outdone, the US Army unveiled plans for an ultra-long range hybrid airship that is capable of flying for three weeks at a time. In other news, renewable energy is heating up around the globe as the EU recently announced that it will import solar energy from the Sahara Desert within 5 years. We also saw a beautiful solar powered flower sprout in Southern California and looked at the worlds first solar-powered soccer ball, which could help the blind play soccer. Finally, we caught wind of an innovative breathing mask that filters CO2 from the air, converts it into energy, and stores it to power a cellphone or portable music player.
Inhabitat's Week in Green: solar buildings, solar stadiums, and an algae-powered lamp
The Week in Green is a new item from our friends at Inhabitat, recapping the week's most interesting green developments and clean tech news for us. The past week Inhabitat saw solar-powered transportation soar into space as Japan successfully unfurled the world's first solar sail aboard its Ikaros spacecraft. We continued our transportation coverage by taking a took a look at a futuristic plant-powered photosynthetic concept car that seats riders within an enclosed jungle canopy. However if the Inhabitat editors commuted to work, it would probably be via these amazing solar-powered shrub cars! In other news, the world of architecture is heating up with the onset of summer as countries around the globe gear up to unveil high-tech sun-powered homes at the European Solar Decathlon. This week we took a look at two of our favorites - the solar shelled Armadillo Box House and Finland's hyper-insulated Luuku House, which is expected to generate more energy than it consumes. We also celebrated the launch of the 2010 World Cup by taking a look at the technologies behind five stunning green stadiums that will be hosting this year's games in South Africa. Speaking of the World Cup, this week were also excited to see the unveiling of a brand new version of the sOccket, an energy-generating soccer ball that scores a goal for green power in developing countries. We also took a look at a cheap solar-powered refrigerator for the developing world that can be assembled using local materials and could save millions of lives by storing and distributing vaccines. Renewable energy was also a hot topic this week -- the UAE is blazing a trail with plans to construct a record-toppling solar plant that eclipses the size of every photovoltaic farm to date. We also saw home-grown algae power make its domestic debut in this gorgeous green Latro Lamp, which is fueled by a pond-scum powered bio-battery. And renewable energy took to the streets this week as telecom provider Orange unveiled a set of spiffy set of thermoelectric galoshes that charge your cellphone using heat from your feet. Finally, this week we unveiled some incredible new uses for everyday materials as we announced the grand-prize winners of our 2010 Spring Greening DIY Design Competition. Speaking of innovative examples of repurposed design, we were also blown away by this open-source printer made from LEGO bricks and a felt-tip pen. And if you insist on continuing to use a standard printer, you can rest assured that there's an inspired re-use for those expired ink cartridges - Australia recently unveiled a bike path made from them!
IKAROS successfully stretches wings, prepares for solar spaceflight
Though it may look like a collection of tinfoil and string, the photo above depicts what may be the first solar sail to actually propel a spacecraft. Japan's IKAROS (Interplanetary Kite-Craft Accelerated by Radiation of the Sun) just unfurled the 7.5 micron (.0003-inch) thick polyimide membrane 7.4 million kilometers from Earth this week, and expect its embedded thin-film solar panels to propel the craft past Venus and towards the dark side of the sun. Because wax and feathers only get you so far.
Inhabitat's Week in Green: wind power, shoe power, and the world's largest laser
The Week in Green is a new item from our friends at Inhabitat, recapping the week's most interesting green developments and clean tech news for us. This week Inhabitat showcased several smart new technologies that harness clean green energy from unexpected (and undeniably awesome) sources. Volcanoes may be the bane of air travel as of late, but Indonesia has hatched a plan to harness their geothermal might to produce 4,000 megawatts of power. Meanwhile The Netherlands is turning the tide on hydroelectric power by upgrading their dikes with energy generating underwater turbines. In other news, harnessing energy from stars may seem like an out-of-this-world proposition, but that's precisely what scientists are attempting to achieve as they fire up the world's largest laser in an attempt to grasp the holy grail of energy: nuclear fusion. And speaking of out-of-this-world developments, this week Japan announced plans to launch its solar "Ikaros" spacecraft, which will sail through the stars using rays of light. While keeping stride with these developments we also looked at several innovative technologies that stand to shape the future of consumer tech. Looking to put some punch in your step? Then try these energy generating piezoelectric shoes on for size. We also brought an eye-opening new night vision technology to light that is so thin, lightweight, and cheap that it can integrated directly into eyeglasses, car windows, and cell phone cameras. Even our canine friends are getting high-tech upgrades -- check out this geo-tagging rescue dog jacket that can be used by people in peril to transmit emergency messages. Finally, this weekend marks the start of the 2010 Shanghai World Expo, which we're celebrating by showcasing the top six futuristic pavilions that harness high-tech green building strategies. But if you only check out one, make it the amazing interactive Dream Cube, which is made from recycled CD cases and features a stunning LED-laden facade that changes color with a wave of the hand.
