A 132-meter long vessel will soon be making its maiden voyage, but rather than using copious quantities of diesel while traversing the Atlantic, it'll be receiving a good bit of help from the computer guided kite attached to its bow. The $725,000 device (600 square metres of sail) will be tethered to a 15-meter high mast and will fly some 300 meters above the ship. The kite is constructed as a twinskin kite which keeps its airfoil shape due to internal air pressure: A set of small mesh openings in the leading edge allows air into the opening between the front and back side. This form of kite is an airfoil, not a spinnaker, the difference is huge: A spinnaker is effectively a large bag to catch the wind, while a kite works best by having air moving faster on one side than the other. Among other things, this means that a kite allows you to sail much faster at an angle to the wind instead of straight downwind.| Reactions: |
Rinspeed will at the Geneva Motor Show (March 6th thru 16th, 2008), showcase their sQuba Concept Car. The makers claim that it is the world's first real car with the capabilities to not only drive on land but also dive underwater with the use of two propellers in the stern and two powerful jet drives in the bow which propel the vehicle which has a steel chassis, while its lightweight body panels are made of carbon nanotubes. An electric motor provides rear-wheel drive while on roads. Underwater, two propellers in the stern and two jet drives in the bow propel the vehicle. With zero emissions, the design is even environmentally friendly, eliminating any pollution into the sea.| Reactions: |

For the past two years, Europe's Venus Express orbiter has been studying Earth's planetary neighbor up close. Mission scientists have released a new collection of findings and amazing images. They include evidence of lightning and other results that flesh out a portrait of a planet that is in many ways like ours, and in other ways hellishly different, such as surface temperatures over 400C and air pressure a hundred times that on Earth. | Reactions: |
