D-Dalus - an entirely new genre of aircraft arrives
By Mike Hanlon
Austrian research company IAT21 has presented a new type of aircraft at the Paris Air Show which has the potential to become aviation's first disruptive technology since the jet engine.The D-Dalus (a play on Daedalus from Greek mythology) is neither fixed wing or rotor craft and uses four, mechanically-linked, contra-rotating cylindrical turbines, each running at the same 2200 rpm, for its propulsion.
The key to the D-Dalus' extreme maneuverability is the facility to alter the angle of the blades (using servos) to vector the forces, meaning that the thrust can be delivered in your choice of 360 degrees around any of the three axes. Hence D-Dalus can launch vertically, hover perfectly still and move in any direction, and that's just the start of the story.

Canada Introduces New, Plastic Cashby Eyder Peralta
The Bank of Canada introduced brand new polymer bills, yesterday. As the Toronto Sun puts it, the move is designed to use high-tech materials to "thwart counterfeiters." The notes, which have two see-through windows, are also cheaper to make and last about 2 1/2 times longer than paper money.

Europeans Plan to Launch Prototype Wingless, Reusable Spaceship By 2013
By Rebecca Boyle
The European Space Agency announced plans today to launch a privately built snub-nosed space bullet, which sort of resembles a wingless, truncated space shuttle, within the next two years. Thales Alenia Space, builder of several International Space Station components and many European satellites, is manufacturing the spacecraft.
The Intermediate eXperimental Vehicle is a 2-ton “lifting body," with no wings whatsoever and only two moving flaps that will control its movement. The spacecraft will launch on an ESA Vega rocket, reaching speeds of 16,000 miles per hour and 280 miles in altitude. Then it will return to Earth much like the shuttle, only with flaps guiding it instead of glider wings. It will parachute to a splash landing in the Pacific Ocean.
E uma dica que não sei se já dei, mas cá vai, Make Human é um Programa Grátis 3D de Modelação de Figura Humana, tanto Masculina, como Femenina.
E o que é especialmente porreiro neste programa é que se pode exportar o Modelo para o formato .Obj, ir à pasta home/xxxxx/makehuman/exports, onde xxxxx é o vosso nome, e importar para Wings 3d, aqui, com um Modelo Masculino,
Para o Ubuntu, é só ir aqui:
