Oh good. We used to be smart enough to keep this sort of thing secret for awhile and let the Navy perfect the application. Then again, the researchers who figured it out are probably Chinese anyway.

Watch for this break through to be used in the America’s Cup yacht racing.........

Why not paint the ships with this ?

Have you seen the new boat for America’s cup? It uses submerged airfoil (wayerfoils) to completely lift the boat out of the water and the hydrofoils provide stability below. A really amazing sailboat.

I think engineers from Dubai designed and built the boat.

Laughed so hard my dog came over to make sure I was ok.

Very funny, and probably true.

re: “MADMAN!”

Back in 1966 I flew with VP-24 in the P2V. The Magnetic Anomaly Detector was fascinating. Also liked the way the smoke/flare block was shot aft by an air cannon regulated by the airspeed. It was fired rearward at the same velocity as forward airspeed, so it dropped straight down over the MAD contact.

Neat!

Urzhumov is turning to electromagnetic fields and the dense concentration of charged particles found in saltwater.

I had this same idea, back when The Hunt for Red October came out, and I learned about MHD drives. As a boat owner, I was fascinated with drag reduction ideas. I figured, if an MHD could in theory move sea water that way, one should be able to do so on the water contacting parts of the vessel. Dang..

Yep, a super duper catamaran.........

A close high school friend worked with BMW Oracle Racing, multihull challenge for the America's Cup. He held the position of Manager of the Instrumentation, Analysis and Performance Optimization Department with his primary focus on their sails.......He had worked for Dennis Connor since about 1984....

The switch to catamarans in that campaign was his last employment with them. He resigned afterwards since the America's Cup yachts became to high tech and lost all semblance of the yachts that the Cup was originally created for.

Back in 77/78? I was in Newport for the cup. I remember Ted Turner being on our boat for a bit. I was too young to take it all in. I was in my teens and chasing tail most the time.

I have a big picture of Dennis on the bow of his Stars&Stripes holding an anchor I made for him. I was shocked when we got the order, because I had assumed that everything would be “light weight”, but there were regs stipulating anchor weight.

Interesting......Considering that weight is a factor on those boats and whichever port they are harbored in, they're always docked when not on sea........Why would they have an anchor which would take up space in the front hull which is usually reserved for additional sails?

Dennis Connor never forgot his beginnings with Sunfish sailboats, and occasionally drops in to chat at Sunfish sailing forum discussions.

Urzhumov says that for an actual ship or submarine to ever use such a device, it would need a nuclear reactor to power it, given the enormous energy requirements to cloak an object of that size. That does not mean, however, that a smaller diesel vessel could not power a smaller cloaking device to shield potentially vulnerable protrusions from detection.

Urzhumov also says that his theories and calculations have many potential applications outside of the ocean. Similar designs could be used to create a distributed ion propulsion system for spacecraft or to suppress plasma instabilities in prototypes for thermonuclear nuclear fusion reactors.

Do you realize what that means! Controlled nuclear fusion reactors are only ten 10 years away!
