Typhoon: biggest nuclear-powered submarine





The Typhoon class submarine is a type of nuclear-powered ballistic missile submarine deployed by the Soviet Navy in the 1980s. With a maximum displacement of 26,000 tonnes, Typhoons are the largest class of submarine ever built. A Typhoon class submarine can stay submerged for periods up to 180 days in normal conditions, and potentially more if necessity arises.

Lockheed-Martin P 791



The P-791 is an experimental aerostatic/aerodynamic hybrid airship developed by Lockheed-Martin corporation. The first flight of the P-791 was made on 31 January 2006 at the company's flight test facility on the Palmdale Air Force Plant 42. In such designs, part of the weight of the craft and its payload are supported by aerostatic (buoyant) lift. Critics of the hybrid approach are: difficult to control and protect on the ground, and have relatively poor aerodynamic performance.

Chicken Head Tracking



Pennywhistle Productions

Chickens have a great ability to keep their heads stable. Our bodies use a gyro-like mechanism in our ears which has 3 mutually orthogonal inertial measurement devices. Modern motion processors use something called an Inertial Measurment Unit (IMU). These devices provide movement data which can be used to compensate for the movement. Chickens apparently have the same type mechanism only with a higher update rate.



Bugatti Veyron VS JET Fighter



In 2000 Volkswagen AG founded Bugatti Automobiles SAS and introduced the EB 16/4 Veyron concept, a 16-cylinder quadruple turbo charged car with 1001 hp DIN (736 kW), 0-100 km/h (0-62 mph) in 2.5 sec, and a top speed of 407 km/h (253 mph), at the Paris, Geneva and Detroit auto shows. Development continued throughout 2004 and the EB 16/4 Veyron was promoted to "advanced concept" status. In July 2005 Bugatti Automobiles SAS announced that the car would officially be called the Bugatti Veyron 16.4. According to Car and Driver, the Veyron's fuel consumption at 253 mph was 3.0 mpg (78 L/100 km). At full throttle, its 100 L (26 US gal/22 imp gal) fuel tank would empty in just 12 minutes 46 seconds. After 15 straight minutes at 253 mph the tires would melt. The latest limited edition version of the Bugatti Veyron 16.4. It costs $2.3 million (not including tax).
