Renewable Energy

Electron microscope images of the nanometer-sized rods of titanium dioxide that cover the ...

Researchers at Ohio State University (OSU) have created a dye-sensitized solar cell that stores its own power by "breathing" air to decompose and re-form lithium peroxide. Its creators believe the device, which effectively combines a battery and a solar cell in one, could reduce renewable energy costs by 25 percent.  Read More

A new study conducted at MIT has examined the potential of pressure-retarded osmosis (PRO), a technique that generates electricity from the difference in salinity between two pools of water separated by a membrane. According to the researchers, tweaking the size of the membrane could help generate electricity much more cheaply than ever before.  Read More

Scientists at PNNL have developed a new liquid alloy electrode that can improve the perfor...

A new battery electrode designed at the Pacific Northwest National Laboratory (PNNL) combines liquid-state cesium and sodium to dramatically improve on the efficiency, safety and useful life of sodium-beta batteries (NBBs). If the technology is scaled up successfully, the advance could help build a smart electric grid that makes better use of renewables such as solar and wind.  Read More

The tattoo biosensor for monitoring lactate levels that has been converted into a sweat-po...

Last year, researchers at the University of California, San Diego (UCSD) unveiled a sensor imprinted on a temporary tattoo that, when applied to the skin, is able to continuously monitor lactate levels in a person's sweat as they exercise. Now the research team has leveraged the technology to create a biobattery powered by perspiration that could lead to small electronic devices being powered by sweat.  Read More

The Brighton i360, by architecture firm Marks Barfield

Popular English tourist spot Brighton will soon gain a new landmark to join its famous pier. The same team responsible for the London Eye ferris wheel has started work on a large-scale observation tower dubbed the Brighton i360. The observation tower will feature a large glass pod that offers views of up to 30 miles away (48.2 km) on a clear sunny day.  Read More

Harvesting electricity from condensation could take renewable power to remote areas (Photo...

MIT researchers have found a way to generate small amounts of electricity from condensation, by having electrically-charged droplets jump between superhydrophobic (water-repelling) and hydrophilic (water-attracting) metal plates. The advance could be especially useful in remote areas or developing countries, not least because it produces clean water as a side product.  Read More

The Singapore Sports Hub, by DP Architects (Photo: DP Architects)

Work was recently completed on a big, bold, and presumably very expensive architectural project – and for a change, it's not located in Dubai or China. The Singapore Sports Hub is a mammoth new sports complex containing the East Asian city state's new National Stadium: a 55,000 capacity venue that boasts the notable achievement of being the world's largest dome structure.  Read More

WindStream Technologies says it has installed the world's largest wind-solar hybrid genera...

Generating renewable electricity at home or commercial buildings is becoming increasingly viable. WindStream Technologies has installed what it says is the world's largest wind-solar hybrid array on an office roof in Kingston, Jamaica. The array is expected to generate over 106,000 kWh annually.  Read More

The giant floating Energy Duck concept by artists Hareth Pochee, Adam Khan, Louis Leger an...

A group of British artists have conceptualized a giant solar harvesting floating duck as part of the 2014 Land Art Generator Initiative Copenhagen design competition. Dubbed Energy Duck, the giant structure has been designed not only to generate clean electricity for the local residents of Copenhagen, but to also provide a unique visitor center.  Read More

Dr Jon Major says magnesium chloride could replace toxic cadmium chloride in CdTe solar ce...

Tofu has long been touted as a good way to clean out your insides, but now a researcher at the University of Liverpool says an ingredient in tofu could also be used to clean up solar cells. The hope is that the naturally occurring substance could replace a key ingredient in thin film solar cells that is highly toxic and expensive to produce.  Read More
