World's first solar battery claimed to "run on light and air"

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

MIT study could slash the cost of renewable osmotic power

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

Liquid metal alloy electrode boosts potential of sodium-beta batteries

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

Temporary tattoo lactate sensor converted into sweat-powered biobattery

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

Vertical cable car under construction in Brighton, UK

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

New device generates electricity from condensation

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

World's largest dome structure completed in Singapore

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.

Tofu ingredient could clean up solar cell recipe

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
