D-Dalus: A new kind of aircraft propulsion system made of rotating cylinders

D-Dalus hovercraft

Austrian Innovative Aeronautical Technology (IAT21), an Austrian engineering firm debuted a new type of hovercraft at the Paris Air Show this week. They claim the hovercraft can take off and land vertically without using any rotor blades or fixed wings.

Why It Will Be at Least 200 Years Before Interstellar Travel will Be Possible

astrochemistry

We won’t have enough power until 2211 for interstellar travel.

Interstellar travel won’t be possible for at least 200 years, according to a former NASA propulsion scientist who has some new calculations. And by then, the spaceships we would design for the trip will be obsolete.

Commute Through the Skies with the First Commercial Jetpack

The world’s first factory making space-age JET PACKS is going into production.

It is the perfect way for city high-fliers to miss the morning rush hour. A company is set to produce the first commercial JETPACKS – and one could be yours for just £50,000.  The traffic jam-beating packs will be manufactured after a multi-million pound deal was signed with an international aircraft company this week.  (Video)

Year 2036: Mars colonization and a date with destiny

Year 2036: Mars colonization and a date with destiny

Dr. Neil deGrasse Tyson host of the NOVA scienceNOW PBS program

From a half billion kilometers away, the message was powerful. In 1994, fragments of the Shoemaker-Levy 9 comet slammed into Jupiter. The earth-size fireballs ejected into space were captured and relayed back to be seen again and again in Internet replay. The message: we need a foothold in space if our species is to survive.

Robotic sea bream from the University of Kitakyushu 

Engineers at the University of Kitakyushu have developed an underwater survey robot that looks good enough to eat. “Tai-robot-kun,” a 7-kilogram (15.4 lb) robotic sea bream (red snapper) with a silicone body covered in realistically hand-painted scales, features a unique propulsion system that allows it to move its tail and drift silently through the water like a real fish. Second video after the jump.

The Fastest Rocket Sled On Earth

 The Fastest Rocket Sled On Earth

High-speed photography shows the shock waves produced by the rapid acceleration of the 4-stage rocket sled.

It might make the ultimate amusement park ride, if anyone could survive. Hitting hypersonic speeds of Mach 8.5–that’s 6416 mph, in civilian terms–a 4-stage rocket sled took just 6.04 seconds to blast the more than 3-mile length of track at Holloman Air Force Base in New Mexico.
