US Navy tests electromagnetic gun

[ …..The U.S. Navy test fired an incredibly powerful new big gun designed to replace conventional weaponry aboard ships. Sci-fi fans will recognize its awesome power and futuristic technology.
The big gun uses electromagnetic energy instead of explosive chemical propellants to fire a projectile farther and faster. The railgun, as it is called, will ultimately fire a projectile more than 230 miles (370 kilometers) with a muzzle velocity seven times the speed of sound (Mach 7) and a velocity of Mach 5 at impact.
The test-firing, captured on video, took place Jan. 31 in Dahlgren, Va., and Navy officials called it the “world’s most powerful electromagnetic railgun.”….
… “I never ever want to see a Sailor or Marine in a fair fight. I always want them to have the advantage,” said Chief of Naval Operations, Admiral Gary Roughead. “We should never lose sight of always looking for the next big thing, always looking to make our capability better, more effective than what anyone else can put on the battlefield.”]
Pimp my satellite dish!
Yet another post for the antenna aesthetics category.
‘WijKunst’ (translated ‘District-art’) is a new project from Autobahn in Utrecht, Holland featuring pimped satellite dishes:-) Examples shown below are taken from http://arboblog.pl/pimp-my-satellite-dish/
EMF water fountain design info
One of the problems I have had in relation to getting to grips with the technical side of designing the aquatic aspects of the EMF is the difficulty in finding comprehensible information available to a non-engineer on the subject. After numerous searches I finally hit on a commercial website that offers PDF files to help out with everything from the fundaments of designing a water fountain, to budget and planning issues and gives descriptions of how different pumps, nozzles and jets work. Very useful.
