Around 60 percent of the homes in the Netherlands are row house terraces, with around a quarter of those built in the post-war period. While these constructions characterize much of the Dutch urban landscape, they weren't exactly built with energy efficiency as their first priority. A team of Delft University students has developed a concept for a solar-powered skin designed to optimize energy usage, while also preserving this classic Dutch architecture.  Read More

This colorful American flag is in reality a functional  and transparent solar cell (Photo:...

A beautiful stained glass installation, a colorful billboard, or rows of windows on an office building ... all as electricity-generating solar cells? New research at the University of Michigan gives a method for creating such transparent and colorful solar cells using a hybrid silicon/organic composition, and furthermore avoids some of the problems of previous colored and transparent solar cells.  Read More

The UK-based Limpley Stoke Eco House has been designed from scratch with sustainability in...

British architectural firm Hewitt Studios LLP recently completed work on the 400 sq m (4,305 sq ft) UK-based Limpley Stoke Eco-House. Designed with a focus on sustainability and energy efficiency, the futuristic home features more green technology than you can shake a (sustainably-sourced) stick at, including rainwater collection, passive ventilation, solar power, and an EV charging point.  Read More

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.  Read More

The NTS SunCycle charges its battery using a built-in solar panel

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

Expedition users can switch between the turbine, solar and hand crank power

Powertraveller adds an ultra-versatile portable charger to its gadget charger line. Not only does the new Powermonkey Expedition include standards like a clamshell solar panel, AC adapter and crank charger, it complements them with a portable wind/river turbine. Carry the kit on your adventures and simply connect the generator component that's most suitable for the current conditions.  Read More

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.  Read More

In 2012, researchers from the University of Florida reported a record efficiency of 8.6 percent for a prototype solar cell consisting of a wafer of silicon coated with a layer of graphene doped with trifluoromethanesulfonyl-amide (TFSA). Now another team is claiming a new record efficiency of 15.6 percent for a graphene-based solar cell by ditching the silicon all together.  Read More

Rawlemon has designed an aesthetic take on  solar power devices

Despite their noble cause of harnessing clean, renewable energy from the sun, solar panels tend to be aesthetically uninspiring. Solar start-up Rawlemon aims to change all that with a new, and undeniably beautiful, take on concentrated photovoltaic (CPV) technology.  Read More

Local luminaries fire up the now solar-powered Las Vegas sign

Last week, the world's attention was focused on Las Vegas thanks to the Consumer Electronics Show. With that backdrop of bleeding-edge technology, the city's iconic welcome sign received a little technological makeover of its own.  Read More
