Energy riches fuel bitcoin craze for speculation-shy Iceland

Energy riches fuel bitcoin craze for speculation-shy Iceland

Technology
Iceland is expected to use more energy "mining" bitcoins and other virtual currencies this year than it uses to power its homes. With massive amounts of electricity needed to run the computers that create bitcoins, large virtual currency companies have established a base in the North Atlantic island nation blessed with an abundance of renewable energy. The new industry's relatively sudden growth prompted lawmaker Smari McCarthy of Iceland's Pirate Party to suggest taxing the profits of bitcoin mines. The initiative is likely to be well received by Icelanders, who are skeptical of speculative financial ventures after the country's catastrophic 2008 banking crash. "Under normal circumstances, companies that are creating value in Iceland pay a certain amount of tax to the government," McCart...

Pollution particles fuel large storms, research shows

Science
Jan. 26 (UPI) -- New research suggests scientists have underestimated the importance of particulate matter as a driver of storm size and intensity.Scientists have previously proven that aerosols, particles suspended in the atmosphere, can influence weather and climate. With their latest study -- published this week in the journal Science -- researchers with the Department of Energy's Pacific Northwest National Laboratory showed the smallest particles can encourage the formation and increase the intensity of storms."We showed that the presence of these particles is one reason why some storms become so strong and produce so much rain," PNNL researcher Jiwen Fan, lead author of the new study, said in a news release. "In a warm and humid area where atmospheric conditions are otherwise very cle...
Yemen's cities running out of fuel and clean water in 'imminent catastrophe,' UN says

Yemen's cities running out of fuel and clean water in 'imminent catastrophe,' UN says

World
A Saudi-led coalition fighting Yemeni rebels eased an air, land, and sea blockade of Yemen a week ago, but it is still keeping commercial ships with food and fuel from docking and unloading their cargo in the country, putting millions at risk of starving, the United Nations said this weekend. Millions of Yemenis depend on those supplies, and without fuel, health and water facilities can’t run. So Yemen’s cities are running out of clean water, the chiefs of several United Nations agencies and other top humanitarian officials said in a statement Saturday. “Urban water networks in seven cities have run out of fuel and now depend on humanitarian organizations to fill in the gap,” the officials said. “Other cities will shortly be in a similar situation if the blockade is not lifted, which wo
Valero awarded $157M fuel contract for Israel

Valero awarded $157M fuel contract for Israel

Business
Oct. 16 (UPI) -- In a new deal struck between the Defense Logistics Agency and Valero Marketing and Supply Co., Pentagon officials announced Friday the allocation of $ 157 million to the Texas-based company in search of various types of fuel.The contract is designed to be a fixed-price in terms of base cost, but the deal does take into account economic-price-adjustments, so the totality of the contract can be adjusted upward or downward depending on external market factors.The contract acquisition was said to be competitive among the four defense contracting companies who submitted proposals to the Defense Department. The award is a one-year base contract with a one-year option period, plus a 30-day carryover. Work will occur in Texas, with a completion data of Sept. 30, 2017.The work comp...
'Cyborg' bacteria deliver green fuel source from sunlight

'Cyborg' bacteria deliver green fuel source from sunlight

Science
Scientists have created bacteria covered in tiny semiconductors that generate a potential fuel source from sunlight, carbon dioxide and water.The so-called "cyborg" bugs produce acetic acid, a chemical that can then be turned into fuel and plastic. In lab experiments, the bacteria proved much more efficient at harvesting sunlight than plants.The work was presented at the American Chemical Society meeting in Washington.Researchers have been attempting to artificially replicate photosynthesis for many years. Solar panel bugsIn nature, the green pigment chlorophyll is key to this process, helping plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose.But despite the fact that it works, scientists say the process is relatively inefficient. This has also been a big ...
