EDINBURGH, April 10 (Xinhua) -- Researchers at the University of Edinburgh have developed technology that enables solar panels to detect broadband signals and makes internet access fuelled by the power of the sun possible. The technology allows data to be transmitted on the World Wide Web using daylight, and, in addition, solar energy can be used to power such a device, as well as detect and carry data, the University of Edinburgh said in a statement on Thursday. This could enable self-sufficient wireless communications in remote areas, in developing regions with no web infrastructure, or in emergency situations, the statement said. Prototypes of the system have reached transmission ...

Solar power will slowly squeeze the revenues of petro-rentier regimes in Russia, Venezuela and Saudi Arabia. They will have to find a new business model, or fade into decline Solar power has won the global argument. Photovoltaic energy is already so cheap that it competes with oil, diesel and liquefied natural gas in much of Asia without subsidies. Roughly 29pc of electricity capacity added in America last year came from solar, rising to 100pc even in Massachusetts and Vermont. "More solar has been installed in the US in the past 18 months than in 30 years," says the US Solar Energy Industries Association (SEIA). California's subsidy pot is drying up but new solar has ...

Well-known physicist Michio Kaku and other members of the American Physical Society asked Congress to appropriate $100 million to harden the country’s electrical grid against solar flares. As shown below, such an event is actually the most likely Armageddon-type event faced by humanity. Congress refused. Kaku explains that a solar flare like the one that hit the U.S. in 1859 would – in the current era of nuclear power and electric refrigeration – cause widespread destruction and chaos. Not only could such a flare bring on hundreds of Fukushima-type accidents, but it could well cause food riots globally. Kaku explains that relief came in for people hit by disasters like ...

LiveScience.com An experimental "mini heart" could help people with a medical condition that causes blood to pool in their veins by pumping their blood through the vessels and back to the heart, researchers say. The mini hearts are tiny pumps, consisting of a cuff of heart muscle cells. Once implanted to surround a vein, they could contract rhythmically, squeezing blood through the vessel. A patient's own stem cells could be used to make the mini heart, decreasing the chances of tissue rejection, researchers say. "We can create a simple version of the heart, outside a person's own heart," and by placing it in the lower extremities, significantly improve ...

Cherry trees typically take about a decade to bloom after sprouting from seeds. But “space cherries” apparently take about half that time. Astronaut Koichi Wakata, now commander of the International Space Station, carried cherry pits descended a famous historical tree with him into space five years ago. About 265 pits produced from the fruit of the 1,250-year-old “Chujohimeseigan- zakura” cherry tree were carried into space, and some of them have come into bloom within four years, reported The Asahi Shimbun. The ancient tree is a variant of the “yamazakur” wild cherry species and previous attempts to grow young trees from its fruit have proven ...

WASHINGTON, April 3 (Xinhua) -- China remains the leading destination for clean energy investment in 2013 as global investment kept declining in 2013, according to a report released on Thursday. China remains the leading regional and global clean energy market, attracting 54.2 billion U.S. dollars in 2013, 6 percent lower than that in 2012, said the report by the Pew Charitable Trusts. The report said the worldwide investment in clean energy kept declining in 2013 after it reached its peak in 2011, mainly dragged down by the curtailment of incentives in Europe region, including Europe, the Middle East and Africa. Clean energy finance in the European region slid sharply for the second ...

Google Earth had quit working on my computer (pclinuxos, kde64, fully updated). And it was no longer in the repository. I had deleted it but wanted to try again to see if I could make it work. I found the following, tried it and, so far anyway, it is working. Just go to terminal, paste this command and press enter and it will download and install it for you: wget http://dl.google.com/earth/client/current/GoogleEarthLinux.bin && chmod +x GoogleEarthLinux.bin && ./GoogleEarthLinux.bin It can't get any easier. I guess the person who wrote it is assuming that everyone knows how to open a terminal and know how to go to "root" (which is easy but if no one has ...
Tokyo student invents levitation in 3D space

A Tokyo student along with fellow researchers has managed to float objects in a 3D space, using ultrasound. Yoichi Ochiai, a University of Tokyo graduate, together with Takayuki Hoshi and Jun Rekimoto, have found out the way to levitate light objects and move them around in a 3D space. Even though ultrasound levitation has been possible for nearly 40 years, Ochiai says this is still new. "Nobody was able to move objects in a 3D space," he says. "I think as long as objects don't move in a 3D environment, there's not much use for this kind of technology, and my research here at Tokyo University was the first to pull it off." At the University of Tokyo Komaba ...

Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology, Sweden. On Monday 31 March the Intergovernmental Panel on Climate Change (IPCC) presents their report on the impacts of climate change. Carbon dioxide emissions from the energy and transportation sectors currently account for the largest share of climate pollution. However, a study from Chalmers now shows that eliminating these emissions would not guarantee staying below the UN limit. Emissions from agriculture threaten to keep increasing as global meat and dairy consumption increases. If agricultural ...
