A new advancement in solar cells could enable solar power in areas plagued by frequent overcast skies. Scientists from the University of British Columbia (UBC) have developed a cheaper and sustainable method to build biogenic solar cell, using bacteria that converts light to energy and generates a current stronger than any previously recorded from a solar cell, while efficiently dimming light. The researchers believe the discovery could eventually lead to solar cells that are as efficient as the synthetic cells used in conventional solar panels. “Our solution to a uniquely B.C. problem is a significant step toward making solar energy more economical,” Vikramaditya Yadav, a professor in UBC's department of chemical and biological engineering who led the project, said. Solar cells convert light into electrical current for solar panels. Previously, scientists have attempted to build biogenic solar cells by extracting the natural dye that bacteria use for photosynthesis. … [Read more...] about Bacteria-Powered Solar Cells Prevail on Cloudy Days
New power solar
A NEW £7m solar farm is now operational, producing enough electricity to power one of the north's largest water treatment plants.NI Water has today drastically reduced its carbon footprint by the launch of the new solar farm on a 33 acre site on the eastern shore of Lough Neagh. The new 24,000 panel solar farm will power the Dunore Water Treatment Works (WTW) in south Antrim. and is expected to save over half a million pounds annually in energy costs for the company.As well as meeting the energy needs of the Dunore WTW, the project will also enable the company to contribute spare capacity to the grid.NI Water is Northern Ireland's biggest user of electricity and Dunore is its third largest site in terms of energy consumption accounting for 7 per cent of the company's annual usage.Speaking at the completion of the latest project, NI Water CEO, Sara Venning said the new solar farm is another step in reducing the company's carbon footprint.“As the largest user of electricity in … [Read more...] about New £7m solar farm powering one of the north’s largest water treatment plants.
SUNNYVALE, Calif.--(BUSINESS WIRE)--May 1, 2018--Alta Devices, the world-record holder for single junction solar cell efficiency, announces the launch of its fourth-generation solar cell technology (“Gen4”), which weighs significantly less than the previous generation technology (“Gen3”) and results in an improved power-to-weight ratio of 160 percent. This technology is critical for tomorrow’s unmanned aerial vehicles (UAVs), solar cars and other electric vehicles. It can be used to generate substantial power over small surfaces with minimal impact to vehicle design criteria.This press release features multimedia.

Spirit Island BUY NOWSpirit Island could be a Bizzaro-world sequel to The Settlers of Catan. Instead of colonizing a newfound landmass, you and your friends team up as the invaded isle's guardian spirits. You'll muster the native population, deploy your elemental powers, and work together to frighten, drive, and otherwise murder the invading settlers off your sacred land. Catan fights back, baby!Wonderfully complex but not excessively complicated, Spirit Island is the best cooperative game of the decade (yes, even better than Pandemic). As spirits, you'll spend your turns building influence on the game board, learning new powers, and picking which ones to use. Meanwhile, the game automates the unceasing advance of the settlers who explore, settle, and ravish new biomes in a set order. The game includes dozens of ways to modulate the difficulty, but even for the easiest modes require an almost preternatural cleverness; your team needs to know which battles to fight, and to discover the … [Read more...] about The 50 Best New Board Games
An interstellar object called 'Oumuamua has confounded astronomers ever since it passed through our solar system in October of last year. Scientists initially thought that the object — the first-ever visitor from another solar system spotted by Earth-based telescopes — was a comet. Later, they considered it an asteroid and even later described it as a possibly comet-like icy body with a rocky crust. Now, scientists have found that in addition to its confusing appearance, 'Oumuamua — an up to 1,300-foot-long (400 meters), cucumber-shaped object — likely has a rather dramatic history. [Danger! Falling Rocks: Meteorites and Asteroids (Infographic)] When astronomers from Queen's University Belfast in Northern Ireland observed the changes in the object's brightness, they found that it is not spinning regularly, like the majority of known asteroids and small bodies in the solar system do. Rather, it is chaotically tumbling. 'Oumuamua's erratic motion might be a … [Read more...] about Something Violent Happened to Our Solar System’s First Interstellar Visitor
