The Coanda Effect

Cannonball-like underwater robots being developed for nuclear reactors

By - July 21, 2011 1 Picture
According to the Associated Press, a recent study has revealed that three quarters of America's nuclear reactors have leaked radioactive tritium from buried pipes that transport water for the cooling of reactor vessels. This tritium could in turn find its way into the groundwater. While industry officials do reportedly check these pipes for leaks, they can only do so in either indirect or costly, labor-intensive manners. Now, however, researchers from MIT are developing tiny, spherical swimming robots that could check on the pipes directly, relaying their findings in real time. Read More

New class of UAVs look more like UFOs

Most Unmanned Aerial Vehicles (UAVs) employ a fixed wing design much like that of a traditional plane. But these designs offer limited maneuverability and payload capacity, require a runway to takeoff and land, and are unable to hover. Vertical Take Off and Landing (VTOL) UAVs get around these problems, usually by employing rotors like a helicopter. Now UK-based company AESIR has developed a VTOL UAV that has no external rotating parts, instead relying on a phenomenon known as the Coanda effect to generate lift. Read More

US$70,000 pedal-powered submarine for two

By - April 16, 2009 10 Pictures
For most of us, the world deep below the ocean’s surface remains a place we have only had the pleasure to experience vicariously, primarily through watching nature documentaries. It's not as if we can just hop in a submarine and go take a look. Well, perhaps we can, if a Russian company's plan to market a two-seater submarine driven by pedal power to the tourist industry is successful. The new underwater vehicle (UV) from Marine Innovation Technologies (MIT) will not only be cheaper to buy and run than existing submersibles, it will be simpler to operate, requiring no special training or expertise.
