Inhabitat's Week of Green: Wind Farms, Algae Power and an Airplane made of Hemp

Inhabitat's guests review the week's top green innovations and clean tech news each week. It's called the Week In Green.

Highways are large, dark surfaces that absorb a lot of sunlight. Wouldn't it be more logical to make them solar-powered? Designer Daan Roosegaarde came up with this idea and it's now becoming a reality. Roosegaarde teamed up with Heijmans Infrastructure to install solar-powered glowing lines on an autobahn in the Netherlands. The test was a success, and it will soon expand to other regions of the country. Masdar is also building a 50 megawatt windfarm for the Sultanate of Oman. It will be the largest in the Gulf states region. The wind farm will produce enough clean energy to power 16,000 homes , and stop 110,000 tonnes (121.254 tons) of carbon dioxide being burned every year. And in the UK, Primrose Solar is teaming up with Solarcentury to construct a 48 megawatt solar farm in Portsmouth. They are hoping to make it the most eco-friendly ground-mounted solar farm in all of the world. Are you convinced that algae is just green slime. Think again: The natural resource can power everything from the light bulb to a whole city. Here's a look at the most impressive algae-powered inventions that could revolutionize the world.

A couple years ago, BMW, Daimler and scientists at the Technische Universitat Munchen announced plans to join forces to create an affordable and safe electric car. This week, the Visio.M 2 seater that weighs in at just 800 pounds, will be shown to the public for the first time at the eCarTec trade event in Munich. Huliypin is blogging again In other green transportation news, Inhabitat was among two teams that completed the challenge to drive 834 miles with a single tank of diesel fuel in the 2015 Audi A3 TDI, proving that it's possible to get from Albuquerque to San Diego without refilling the tank. The world's first hoverboard is finally here, at least according to a couple in California. The couple claims to have developed a functional hoverboard that uses electromagnetics to lift just a few inches off the ground. For urban commuters, Vello Bike has designed a high-performance folding bike that requires just a single kick to fold and roll it into the desired position. This means that you can take the bike on public transit or store it with minimal hassle. And in the world of aviation, Canadian company Hempearth is developing the world's first aircraft made of hemp. The plane is expected to be ready for flight by the end of next year.

While 3D printing has lots of potential in the realm of design however, it also presents problems for law enforcement officials as it allows individuals to make their own guns at home. Last week, a 28-year-old Japanese man became the first person to go to jail for 3D printing after being found guilty of making two guns at home and distributing a video showing others how to make the same. And Inhabitat was present when New York City held its first ever getgeeked conference last week. From 3D-printing pens to tablets that have built-in projectors. Take a look at some of the most useful tech innovations displayed.

Elsewhere 3D printing is well established in the fields of medical and aerospace technologies, but it's just starting to gain traction as an effective construction method. At Maker Faire Rome, the World's Advanced Saving Project unveiled a new type of portable 3D printer that can be used to construct homes out of clay and mud, as well as fibers. The group plans to bring the technology to the most remote areas of the world. In other green-friendly architecture developments the design duo Micaela Colella and Maurizio Barberio have drafted plans for a prefab wooden house with an innovative steel foundation that can be totally recycled, and French designer Philippe Starck recently teamed up with prefab manufacturer Riko to construct a brand new solar and wind-powered home. The two-story house generates 50 percent more energy than it consumes.

With Halloween just around the corner Many of our readers are pulling together awesome costumes for their kids and themselves however, few can match this dad's amazing LED stick-figure costume that makes his daughter, Zoey, look like a glowing stick-figure Minnie Mouse. If you're at a loss for Halloween costume ideas and want to do something gadgety, check out our awesome images of human iPhones Androids and robots as well as Minecraft characters here.
