Transparent coating keeps solar cells cool and efficient throughout the day

Stanford engineers have developed a transparent silicon overlay that can increase the efficiency of solar cells by keeping them cool. The cover collects and then radiates heat directly into space, without interfering with incoming photons. If mass-produced, the development could be used to cool down any device in the open air for instance, to complement air conditioning in cars.

"Unique" hand-made strap discretely adds smart features to any watch

Polish startup uBirds is seeking funding on Kickstarter for Unique, a discrete, handmade, and highly customizable "smart strap" that can fit nearly any wrist-worn timepiece and add smartwatch-like functions to it. Where similar products have gone all-out in the features department, arguably at the cost of style and comfort, the approach for Unique is to blend in through a minimal footprint and a barebones, single-LED interface.

New invisibility cloak hides tiny three-dimensional objects of any shape

Scientists at UC Berkeley have developed a foldable, incredibly thin invisibility cloak that can wrap around microscopic objects of any shape and make them undetectable in the visible spectrum. In its current form, the technology could be useful in optical computing or in shrouding secret microelectronic components from prying eyes, but according to the researchers involved, it could also be scaled up in size with relative ease.

World's largest delta 3D printer could build entire houses out of mud or clay

WASP (World's Advanced Saving Project) is set to unveil Big Delta, reportedly the world's largest delta 3D printer, later this week. This 12-meter (40 ft) tall behemoth was brought to life with the purpose of building nearly zero-cost housing through the use of local materials and as little energy as possible, offering quick and inexpensive relief to disaster areas and addressing the future housing needs of a rapidly growing world population.

Samsung's giant satellite network could enable high-speed internet access across the globe

A highly ambitious proposal recently advanced by Samsung describes the deployment of a huge network of 4,600 near-Earth satellites that would provide internet coverage on a truly global scale. The artificial constellation would more than double the number of working satellites in orbit around our planet and lead to low-latency and (potentially) low-cost access to about 200 GB of internet traffic a month for up to five billion people, no matter their location.

Aluminum "yolk" nanoparticles deliver high-capacity battery recipe

Researchers at MIT and Tsinghua University in China have found a way to more than triple the capacity of the anodes, or negative electrodes, of lithium-ion batteries while also extending their lifetime and potentially allowing for faster battery charging and discharging. The new electrode, which makes use of aluminum/titanium "yolk-and-shell" nanoparticles, is reportedly simple to manufacture and is especially promising for high-power applications.

Study claims perovskite solar cells can recoup their energy cost within three months

Scientists at Northwestern University and the U.S. Department of Energy have found that perovskite cells, one of the most promising solar technologies of recent years, can repay their energy cost over 10 times faster than traditional silicon-based solar cells. The finding confirms that, once issues related to cell longevity are ironed out, perovskite cells could soon bring us solar energy on the cheap, and do so with less impact on the environment over their lifetime.
