For $60, an organization known as Liquipel will take your smartphone, place it in a vacuum and pump a vapor into the chamber. The vapor deposition process spreads a thin film over and contained in the gadget, coating the sensitive electronics with a fabric designed to deflect water — what this material is fabricated from remains a secret. One other nanocoating maker, P2i, will get just a little more scientific with the explanation: “P2i’s patented technology employs a particular pulsed ionized fuel (plasma), which is created inside a vacuum chamber, to attach a nanometre-thin polymer layer over the entire floor of a product. When liquids come into contact with it, they type beads and simply run off” [source: P2i].

Decoy technology has also superior in response to trendy detection systems. The U.S. Military and different navy forces have developed simply-transported, inflatable dummies that not only resemble tanks and other gear visually, but also replicate the thermal or radar signature of that gear. To radar and other long-vary scanners, these dummies are nearly indistinguishable from real tools. A less precise decoy strategy is to flood an space with all types of objects that present up on radar, foto portrait thermal-imaging and listening devices, making it tougher for the enemy to focus in on any particular piece of tools.

“It’s a fairly unremarkable piece of engineering, but it’s turned into this amazing public area,” Green says. The structure is just like most overpasses in U.S. freeway building, and it isn’t typically someplace vacationers visits for its beauty, especially considering the historical structure all through London. However, the London Bridge gives a wonderful location from which to take images of the nearby Tower Bridge.
