Comments Off on UMD scientists invent new water-based battery that won’t catch fire

Researchers at the University of Maryland have invented a new  water -based zinc battery that is safer than a traditional lithium-ion battery, but which doesn’t sacrifice power or usability. The team utilized elements of older zinc battery technology with novel water-in- salt electrolytes to create a battery that is not prone to catching fire. “Water-based batteries could be crucial to preventing fires in electronics, but their energy storage and capacity have been limited – until now,” said study first author Fei Wang in a statement . “For the first time, we have a battery that could compete with the lithium-ion batteries in energy density, but without the risk of explosion or fire.” Their work was recently published in the journal Nature Materials . One of the new battery ‘s improvements over traditional batteries is its ability to overcome irreversibility, the phenomenon in which the charge delivered by the battery at its intended voltage decreases with usage, through a technique that changes the structure of the positively charged zinc ions within the battery. In addition to the battery’s application in consumer goods, it also could prove invaluable in extreme conditions such as the deep  ocean or outer space.

North American climate boundary pushed 140 miles eastward by climate change

Comments Off on North American climate boundary pushed 140 miles eastward by climate change

A historic climate boundary which marks the division between the humid eastern region of North America and the more arid western region has deviated 140 miles to the east of its original location — thanks to climate change . In a study recently published in  Earth Interactions ,  scientists identified three factors that contribute to the formation of the visible division between North American climatic zones: the Rocky Mountains’ ability to disrupt moisture from reaching inland, Atlantic winter storms and summertime humidity that rises northeast from the Gulf of Mexico. In the recent study, lead author and climate scientist Richard Seager of Columbia University sought to explore the boundary — and its history — as a prominent example of “ psychogeography ,” or the relationship between environmental conditions and human decision making. The climate boundary line that runs along the 100th meridian west was first marked in the late 19th century by  geologist and explorer John Wesley Powell. “Powell talked eloquently about the 100th meridian, and this concept of a boundary line has stayed with us down to the current day,” Seager said in a statement . “We wanted to ask whether there really is such a divide, and whether it’s influenced human settlement.” Related: The Gulf Stream is the weakest it’s been in 1,600 years – here’s why that’s really bad news The 100th meridian climate boundary has affected historic development in the United States. Eastern lands have greater population density and infrastructure, and agriculture is dominated by corn , a moisture-loving plant. To the west of the divide, agriculture is dependent on larger farms with crops — such as wheat  — that flourish in arid regions, and urban development is generally more scarce. As climate change affects the historic rainfall and temperature trends of the region, the study predicts that human development will also adapt, with eastern farms adopting characteristics of those historically found west of the boundary line. “Unless farmers turn to irrigation or otherwise adapt, they will have to turn from corn to wheat or some other more suitable crop,” said Columbia University in a statement . “Large expanses of cropland may fail altogether, and have to be converted to western-style grazing range. Water supplies could become a problem for urban areas.” Via Yale Environment 360 Images via  Seager Et Al. and Depositphotos

President Obama Shuns Oil and Notes $5.6 Billion Saved by American Businesses Through Energy Efficiency

Comments Off on President Obama Shuns Oil and Notes $5.6 Billion Saved by American Businesses Through Energy Efficiency

President Obama stepped to the stage at The University of Miami yesterday to deliver an impressive speech on energy policy. Though the President made mention of his efforts to expand oil and gas drilling in the United States, he also made clear that those were not the long-term answer to our energy woes. He outlined the fact that the United States uses 20% of the world’s oil but only has 2% of the world’s reserves and that even if we tried, we couldn’t drill ourselves out of this mess. After setting this clear line of attack the President then went on to talk to the engineering students in the audience about the Energy Department’s energy assessment program which is saving businesses $5.6 billion dollars in energy costs. He then rolled smoothly through our green energy prospects, leaving no stone unturned – from American manufacturing of wind and solar panels to the development of algae fuels . It’s nice to see that at least one politician out there gets the idea that there is more than one way to solve our energy problems – and that most of those ways are green.

We don’t often think about how much space and energy giant online companies take up in the real world. From Apple’s new massive headquarters in Cupertino to Facebook’s giant server farm located off the grid in the arctic, internet big wigs need a lot of space and energy to run each day. That is exactly why Hewlett Packard Company has announced a partnership with microchip developers ARM Holdings Plc and Advanced Micro Devices, Inc. to produce super low-energy servers that could reduce company energy bills by up to 89 percent. The slimming down of the server world, one chip at a time, has been called “Project Moonshot.” Read the rest of HP’s Project Moonshot Aims to Produce Super Low-Energy Servers Permalink | Add to del.icio.us | digg Post tags: advance micro devices , arm holdings , computers , conserving energy , data servers , energy technology , green companies , green computers , green technology , hewlett packard , hp , internet , internet servers , micro chips , microchips , project moonshot , server technology , servers
