Ghost Of The Sea

Is this the U.S. Nay’s follow on to the $195 million Sea Shadow program, the Sea Shadow that’s currently floating on the scrap heap, waiting to be dismantled?

New Stealth Boat Glides Over Gas Layer

A new kind of boat is designed to move quickly and stealthily through water by generating a layer of gas around its underwater surfaces.

The design reduces friction by a factor of 900, according to the New Hampshire company that produced the boat. Its smooth speed makes it ideal for special operations. It could also revolutionize shipping.

Juliet Marine recently unveiled the Ghost, a ship it says can reach speeds of up to 60 miles per hour. The shape of the craft is similar to earlier attempts at making watercraft less visible to radar — notably the Navy’s “Sea Shadow” project of the 1980s.

The phenomenon is called supercavitation. Supercavitation occurs when a projectile moving through water generates a low-pressure zone around its surface. Go fast enough and the low-pressure zone becomes a layer of gas. In that respect the Ghost is similar to a Russian-made torpedo (called the “Shkval,” or squall), though the underwater portion of the boat’s twin hulls are a new design.

Given the massive debt hole the U.S. is already in and that the Sea Shadow ended up being scrapped, I’m not sure the Navy really needs a new “stealth boat” like the Ghost, especially if it’s primary purpose would be to combat pirates. Pirates, for the most part, don’t have radar. The problem isn’t sneaking up on them, the problem is finding them in the first place and we don’t need a “stealth boat” for that.

/the supercavitation technology does, however, appear to be extremely promising in terms of possible commercial shipping applications where time and fuel are money

Your Paper’s Ringing, Are You Going To Bend It?

Do cell phones really need to be thinner, smaller, and bendable?

‘Paper iPhone’ could be next mobile revolution

A pocket-sized computer as thin and flexible as a sheet of paper is set to be unveiled next week. While it’s just a prototype, the researchers say the bendy souped-up smartphone could revolutionize the way we interact with computers.

Called PaperPhone, the new device is a flexible version of e-ink, the digital ink screen found in e-readers such as the Amazon Kindle.

“This computer looks, feels and operates like a small sheet of interactive paper,” said lead PaperPhone creator Roel Vertegaal, the director of Queen’s University Human Media Lab. “You interact with it by bending it into a cell phone, flipping the corner to turn pages, or writing on it with a pen.”

This is interesting technology but, in my opinion, it’s a solution looking for a problem. It seems to me that using “bending” commands would require more physical effort than pushing, pinching, or sliding fingers across a touchscreen.
