The project uses 3d-printed piezoelectric cells applied to each trolley pole, trolley bus elevation, tire and overhead wire. Aluminum consolidated carbon nanotubes , which increase the heat and electrical conductivity of the material embedded within the structure, are combined with the steel frame, concrete-clad helix. The aluminum frames are printed with piezoelectric crystals that generate electricity from the air flow and pressure exerted from the trolleybus and its overhead wire movement. Related: Margot Krasojevic’s solar-powered sand turbine hotel aims to stop the spread of the Gobi Desert Elevated walls further increase the vibration of the trolley-poles, augmented by wind and rain. These vibrations amplify the the piezoelectric cell displacements which, in turn, generate energy. The design will act as an electrical amplifier, and will provide street lighting and WiFi access to immediate neighborhoods. Users will also be able to use the system to power their gadgets and smart cars , while the electric current stimulates root growth in plants. + Margot Krasojevic

European wind energy is now cheaper than nuclear power

Comments Off on European wind energy is now cheaper than nuclear power

Wind energy has officially overtaken nuclear power as the most affordable energy option – at least in countries surrounding the North Sea . In nearby European nations, the cost of wind is now 30 percent lower than nuclear, a promising development in the push for renewable energy around the world. At the rate of present installations, industry group WindEurope predicts these wind farms will generate a full 7 percent of all energy within Europe by 2030. The reason for the drop in price is largely due to the fact that offshore wind farms are becoming cheaper and easier to build. In the past, constructing these farms has been expensive and impractical – and given the relatively low cost of fossil fuels , it simply hasn’t made sense for many companies to invest in the projects. However, the closure of many drilling projects in the North Sea has left offshore installation vehicles without enough work, causing the cost of transporting turbines out to sea to plummet. Other factors which have helped lower the price include low oil and steel prices, reduced maintenance requirements, and the ability to mass produce turbines. Related: The world’s largest floating wind farm will be operational next year While these falling wind power costs only represent a small part of the global energy market, there’s no reason other regions can’t build up a similar capacity. China, for instance, has built so many solar and wind facilities that it’s already on track to exceed its own emissions targets by 2020. And while wind power is currently developing at a slower pace in the US, that may not be true for long – new turbine designs could potentially upend the entire industry and fuel exponential growth on the American side of the Atlantic.

This luxury hobbit hole could be yours for just $1 million

Comments Off on This luxury hobbit hole could be yours for just $1 million

Over 40 years ago architect Arthur Quarmby built Underhill for his family. From the United States to Australia to Japan, Underhill was widely cited as an example of the elegance of earth homes. The 4,000 square foot dwelling is described on the property listing as “the most celebrated house in the West Riding Section of the Peak District;” a description that would fit right in with Tolkien’s description of the Shire. (Don’t tell the Sackville-Bagginses or they might stop by to steal some spoons.) Related: Tour the Tolkien-themed Hobbit Boutique Hotel in the author’s South African birthplace While the home is not overtly described as a hobbit hole , its name (Frodo Baggins hid under the surname Underhill for a time) and round features – namely a round door at the entrance – appear to evoke the beloved stories. Quarmby’s family lived in Underhill for over 40 years with “unalloyed delight,” but they’re now selling it through Wm. Sykes & Son for a little over $900,000. The four-bedroom home on close to one acre of property is located amid the green rolling hills of Holme, England. It centers around a “family recreation area” with a swimming pool, and around the pool are suites for the owners and two children. There’s also a dining area, music room, guest bedroom, and kitchen. In a last hobbity touch, there’s a “stone vaulted cave” where residents can enjoy a peat fire. Bilbo might be able to afford this home after battling a few more dragons. + Underhill Via CNET Images via Wm. Sykes & Son Save

You may be familiar with maglev trains – but designer Margot Krasojevic just unveiled a 3d-printed LED lamp that brings magnetic levitation to your living room! Krasojevic’s ethereal Orbital Levitation Lamp hovers above a semi-conducting base and rotates in thin air when gently pushed. The light can also be hung like a static ceiling pendant. + Margot Krasojevic The article above was submitted to us by an Inhabitat reader. Want to see your story on Inhabitat ?
