Physics-exploiting axe splits wood in record time -Interesting Engineering A new axe design has taken full advantage of known physics to chop the time it takes to split up a log of wood. Finnish inventor Heikki Kärnä is the man behind the Vipukirves Leveraxe and his aim was to redesign the axe using simple principles of physics to make it more efficient and safer.

So what is it about this axe that would convince you to spend the little extra over a traditional design. A traditional axe is a simple wedge of metal on a handle that passes momentum on to the wood when it is struck; if there is enough momentum, the wood splits. Energy Tower: Power for 15 Earths? Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. They've been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. The 3,000-foot tall tower, with a diameter of 1200 feet, would take advantage of the heavy falling weight of cold air.
Why are we a nation of tree-huggers? 3 February 2011Last updated at 15:44 By Jon Kelly BBC News Magazine Plans to transfer ownership of many public forests in England have provoked a huge row. But why are we so protective of our woodlands? Year in Review: Solar industry puts Oregon at center of escalating trade dispute with China View full sizeMotoya Nakamura/The OregonianREC Solar employees install solar panels at Gladstone High School. Plunging solar-panel prices and declining European subsidies are squeezing companies including SolarWorld, a German business that employs 1,000 in Hillsboro. Storms hit Oregon's fast-growing solar sector in 2011 as the state emerged at the center of an escalating international trade dispute rocking the renewable energy industry. State economic development officials had high hopes that solar manufacturing would succeed the semiconductor industry as a big employer, given that the two sectors use similar raw materials and worker skills. But by year's end the picture appeared decidedly cloudy.

It may sound a bit unusual, but tests have shown that the thermal blanket may be just the thing to save the region's glaciers from disappearing completely, for the time being, at least.Armed with nearly 970 thousand square feet of 4 millimeter thick thermal material, workers scramble to cover the highly threatened Presena glacier to protect it from the sun's ultraviolet rays.
Data to be a defining tech trend in 2012 The start of this year was marked by a tech industry obsession with where to put growing mountains of information gathered online and by sensors increasingly woven into modern lifestyles. External drives boasted seemingly unfillable capacities and companies touted services for storing bits and bytes at massive data centers in the Internet "cloud." As 2012 approaches, focus has turned to searching for trends, patterns and other useful insights about people's preferences and behaviors that might be buried in troves of data.
