Sir Isaac Newton vs. the EC There are plenty of formal peer-reviewed industry papers and articles published in specialized international oil & gas journals regarding theoretical “huge volumes” of supposed European nat-gas “reserves”. Supposedly, such reserves would “solve” the absolutely unnecessary self-inflicted European nat-gas crisis. Furthermore, there are lots of curious back-of-the-envelope ´calculations´ plus added blah blah blah with the very same prognosis in mind. And even some European Commission members are on record describing a highly optimistic outlook on how long ( months ! ) would Europe´s natural gas reserves ´easily´ last after Russia stops delivering its traditional and...

Container's material properties affect the viscosity of water at the nanoscale Sep 19, 2013 Enlarge Georgia Tech associate professor Elisa Riedo poses with a glass water bottle and a plastic water bottle. While container materials don't significantly affect the rate at which water pours from bottles of this size, a new study shows that the properties of containers at the nanoscale dramatically affect the viscosity of water. Credit: Rob Felt Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially...

Mimicking humpback whale flippers may improve airplane wing design DURHAM, N.C. -- Wind tunnel tests of scale-model humpback whale flippers have revealed that the scalloped, bumpy flipper is a more efficient wing design than is currently used by the aeronautics industry on airplanes. The tests show that bump-ridged flippers do not stall as quickly and produce more lift and less drag than comparably sized sleek flippers. The tests were reported by biomechanicist Frank Fish of West Chester University, Penn., fluid dynamics engineer Laurens Howle of the Pratt School of Engineering at Duke University and David Miklosovic and Mark Murray at...
