Nature World: A study of climate data taken from trees in the Western US reveals levels of drought that were significantly worse than anything experienced in the past century. The 1930s drought that triggered The Dust Bowl, considered the worst US drought that century, was barely strong enough to make the list of worst droughts, according to scientists at Brigham Young University in Utah, who analyzed the state's climate record back to 1429. "We're conservatively estimating the severity of these droughts...

Lightning rods are so last century: Next-gen lightning protection and harvesting with high-powered lasers
2014-04-11 17:06:44| Extremetech
The standard way of protecting buildings (and their occupants) from lightning is pretty simple: You stick a lightning rod on the roof, and then some kind of conducting channel that takes the huge discharge of electricity and dumps it into the ground. This is a tried and tested method that is used by most of the world's tall buildings. In the case of something vital like lightning protection, I'm usually a firm believer in "if it ain't broke, don't fix it" -- but that was before I read about a new lightning protection system that uses lasers to redirect the lightning, so that it ignores the building entirely and takes a totally new route to the ground.
