Silent Nemo Spy

The United States Navy has recently completed testing of a robotic fish, called Silent Nemo, that performs underwater surveillance missions. Modelled on a bluefin tuna, the Navy hope to use the submersible drone to undertake secret underwater inspections. The Silent Nemo prototype was tested at the Joint Expeditionary Base Little Creek in Virginia by researchers from the Naval Operations Rapid Innovation Cell (CRIC) and Boston Engineering. A similar device known as GhostSwimmer has also been used by Boston Engineering to gather data on tides, currents, wakes, and weather conditions and resembles the swimming style of a large fish. Director of Boston Engineering’s Advanced Systems Group, Michael Rufo, explained, “GhostSwimmer will allow the Navy to have success during more types of missions while keeping divers and sailors safe.”

François Gissy Breaks the Bicycle World Record

A daredevil cyclist reached a world record speed recently on a specially designed rocket-powered bicycle. Francois Gissy clocked up an impressive 333 kilometres per hour in under five seconds on the modified bike at a motor racing circuit in Le Castallet, France. Gissy’s bike was designed by his friend, Arnold Neracher, and features three rocket engines. Over 13 million people have since viewed the record breaking ride footage on YouTube showing Gissy’s run from the perspective of a rear-mounted camera. The super speedy bicycle shoots off and covers just over 400 metres in less than seven seconds. Previously, Gissy’s rocket-powered bike went up against a Ferrari sports car with the vehicle left trailing behind as the bike accelerated with incredible velocity. Vroom!a
