Energy

Harvard physicists Federico Capasso (left) and Steven J. Byrnes (right) are part of a team...

Could it one day be possible to generate electricity from the loss of heat from Earth to outer space? A group of Harvard engineers believe so and have theorized something of a reverse photovoltaic cell to do just this. The key is using the flow of energy away from our planet to generate voltage, rather than using incoming energy as in existing solar technologies.  Read More

By infusing the leaves of an Arabidopsis thaliana plant with nanoparticles, MIT researcher...

In 2010, Stanford University researchers reported harnessing energy directly from chloroplasts, the cellular "power plants" within plants where photosynthesis takes place. Now, by embedding different types of carbon nanotubes into these chloroplasts, a team at MIT has boosted plants' ability to capture light energy. As well as opening up the possibility of creating "bionic plants" with enhanced energy production, the same approach could be used to create plants with environmental monitoring capabilities.  Read More

Landmarks don't come much more iconic than the Eiffel Tower, but if you've ever visited it in person you may have found the first floor mildly underwhelming. Architectural firm Moatti-Rivière aims to change this, and add some sustainable technology to the mix, during a redevelopment of the tower's first floor that's currently underway.  Read More

A team of the university's students has developed a concept for a solar-powered skin to be...

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

The Flavours concept is made up of three types of villa design within the settlement: the ...

Architect Vincent Callebaut has unveiled ambitious plans to create an energy-producing community comprising 45 futuristic villas in the southwestern Chinese city of Kunming. Though likely to remain on the drawing board for the foreseeable future, the Flavours Orchard concept offers plenty of food for thought and some interesting renders to pore over.  Read More

A rubber mat forms the 'carpet,' and sits atop a grid of hydraulic actuators, cylinders an...

Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths.  Read More

The 'pomegranate' design reduces the surface area of the cluster to one tenth of the sum o...

Though the use of silicon in lithium-ion batteries promises a whole new world of energy storage, it also poses several problems to a battery's durability and overall performance. A new electrode design inspired by clusters of pomegranate seeds and developed by researchers at the Department of Energy's National Accelerator Laboratory (SLAC) and Stanford University, overcomes some of these obstacles, bringing lighter and more powerful batteries closer to reality.  Read More

The Energy Bunker was originally constructed in 1943 to serve as a Nazi anti-aircraft bunk...

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 batteries, actually mini fuel cells, could be refilled with sugar as needed (Photo: Sh...

Even today's best rechargeable lithium batteries do lose their ability to hold a charge after a while, and are considered toxic waste once discarded. In just a few years, however, they may be replaced by batteries that are refillable and biodegradable, and that will also have a higher energy density yet a lower price ... and they'll run on sugar.  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
