Former Nazi bunker transformed into green energy power plant

Energy and utilities company Hamburg Energie has joined forces with IBA Hamburg to transform a former Nazi anti-aircraft flak bunker into a green energy power plant. The Hamburg-based "Energy Bunker" has already begun producing energy for the local community, but once running at full capacity will provide up to 3,000 homes with heating, and another 1,000 homes with electricity.

NTS SunCycle gets a little help from above

Although electric bikes definitely are more eco-friendly than exhaust-spewing cars, some people quite rightly point out that the electricity used to charge their batteries typically comes from not-so-green sources such as coal-burning power plants. That's why Santa Cruz-based NTS Works created its NTS SunCycle pedelec cargo bike. Unveiled this Wednesday, it features an integrated photovoltaic panel that's reportedly capable of fully charging the bike's battery within eight hours. Read More

Nanomaterial thermophotovoltaic system increases efficiency and portability of solar power

It’s not a new idea to improve upon traditional solar cells by first converting light into heat, then reemitting the energy at specific wavelengths optimally tuned to the requirements of the solar cell, but this method has suffered from low efficiencies. However, new research at MIT using nanoscale materials finally shows how thermophotovoltaics could become competitive with their traditional cousins, and grant benefits such as storing solar energy in the form of heat to postpone conversion into electricity.

Ford's C-MAX Solar Energi Concept sports rooftop solar panels

A plug-in hybrid car sounds like an excellent way of squaring the circle between the green cred of an electric car and the range and reliability of one that runs on petrol, but what if you live somewhere that’s a bit off the grid? Ford’s answer is its C-Max Solar Energi Concept, which makes its debut at CES next week. The car uses a combination of high-efficiency solar panels and a separate frame roofed with a Fresnel lens to concentrate sunlight on the panels to give it a proper charge without using the engine or plugging into the electrical mains.
