Snoopy inspired me..
 First, the architects built the pyramids, then the rectangular houses. Now for the houses in the shape of airfoil   Regards Andrew

http://www.wired.com/autopia/2010/06...-than-the-wind
http://en.wikipedia.org/wiki/Sailing..._than_the_wind  Aerodynamic coefficient Cx is very small. It is certainly much smaller than in the traditional ship... This is not a traditional sail 2D, but the full 3D structure. Energy is processed and used to drive water propeller. Why can swim backwards and forwards. Like a film with 2D fan. So many of Snoopy Ship has a much higher efficiency due to 3D Andrew

Old ideas in new study:
This gear drive in a helicopter that is bothering me. Another way to get rid of her. By the way, turned out that the rear propeller and also you can get rid of , because the helicopter does not have the torque of the main propeller. The helicopter had already been built. But it had drawbacks: no, for example, could not take full advantage of autorotation, because the propeller with a hole through the center did not have good aerodynamic properties.... http://en.wikipedia.org/wiki/Sud-Ouest_Djinn http://en.wikipedia.org/wiki/File:He..._and_blade.jpg I missed this problem and the propeller is as it is most optimal. Also today after assuming control of the helicopter adjustable nozzle (vectoring nozzle) on the outlet gases from the turbine driven, will be very precise. http://en.wikipedia.org/wiki/Turbomeca_Palouste http://upload.wikimedia.org/wikipedi...ne_of_F-35.jpg In summary the lack of a gear transmission and rear propeller helicopter will certainly reduce weight.
