NASA – Data from a NASA planetary mission have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter’s moon, Europa.
NASA’s Galileo spacecraft, launched by the space shuttle Atlantis in 1989 to Jupiter, produced numerous discoveries and provided scientists decades of data to analyze. Galileo studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.
One of the most significant discoveries was the inference of a global salt water ocean below the surface of Europa. This ocean is deep enough to cover the whole surface of Europa and contains more liquid water than all of Earth’s oceans combined. more> http://twurl.nl/fzsbny

By Jim Duffy – The new Ethernet Routing Switch (ERS) 4000 series switches are designed to help enterprises optimize networks for collaboration, and simplify the convergence of voice, video and data. One of the key new features of the line is a boost in stacking bandwidth from 320G to 384Gbps.
The switches are compatible with Avaya‘s Virtual Enterprise Network Architecture (VENA), a blueprint unveiled a year ago to allow users to optimize the network for business applications and services through virtualization. VENA is competing with other network virtualization and fabric architectures from Cisco, Brocade, HP, Dell, IBM, Extreme, Enterasys, Alcatel-Lucent, and others. more> http://tinyurl.com/mj6z6fx

By Joel Froese – The only requirement to generate electricity is access to a stream with a two-foot drop in water level and two gallons of flow per minute. A hydroelectric system isn’t overly complicated, isn’t difficult to operate and maintain, has longevity, and is often more cost-effective than any other form of renewable power.
The hydroelectric system is powered by water draining from the lake that flows through a turbine, which drives three generators via a belt and pulley system. The generators are three Baldor Electric model L1177T 15hp single-phase induction motors. Driving an induction motor at higher than normal speed generates electricity. more> http://twurl.nl/y7gyb8
