The Mythbusters do the calcs and show that it falls short by a factor of 6!" Link to Original Source top

In addition to being able to traverse a wide variety of terrain, it can also climb poles, the inside of pipes and condiuts, small grooves in walls, and probably more. It can also swim. Many robots can do one of those tasks. This can do them all! That's quite an accomplishment. This has tremendous potential for the maintenance of fiber optic networks, pipelines, and plumbing in large buildings. It also has tremendous potential as a spy device. (I wonder how loud it is?)

One of many application of interests to futurists would be superior solar sails A carbon nanotube sail could reach 4% of the speed of light by just making a close flyby slingshot around the sun.""

'A concept Sky Commuter aircraft that absorbed $6 mil in startup capital is for sale on eBay. The seller appears to be one of the engineers, and the long description associated with the listing is a heartbreaking (and eccentrically punctuated) story of a beautiful, dashed dream...In a brief description of the ship: It has a operational electric gas assisted lexan bubble canopy. Electric controled directional driving and landing lights. Electric Joystick and two foot pedals on both side and the craft was meant to be controlled from either seat. Advanced front dash shell made of Carbonfiber and Kevlar. Rear engine and electronics bay accessible by tilting seats forward and removing the back panel. (3) huge 3 foot lifting fans CCW/CW rotation. This was made to take off in vertical fight and land. It can be landed on water and float like a boat and take off of water. The targeted dream was to lift above it all and not deal with the daily gridlock traffic. Nearly at the finish line it all came to a abrupt stop and all the years and investment and R&D and production, Remains in this one craft shown here.'
StCredZero (169093) writes "In graduate school, I taught a course like this, but this stuff is a step above! The course takes you from the NAND gate, and builds up to basic logic, components like mux, memory, an ALU, cpu, then an object oriented language, an operating system, and old-school video games like Tetris and Space Invaders!
All of the steps build on top of the last one. You literally go from NAND to Tetris and every place in between. If civilization fell, someone who paid attention in this course could restart the hardware and software industry. (Especially if you saw the video on Hand Made Vaccuum Tubes) Have any holes in your CompSci education? This could be just the thing to pull it all together!
The scientists solved a problem that has confounded engineers and scientists for decades: Individual nano-size building blocks such as nanotubes, nanosheets and nanorods are ultrastrong. But larger materials made out of bonded nano-size building blocks were comparatively weak. Until now.
"When you tried to build something you can hold in your arms, scientists had difficulties transferring the strength of individual nanosheets or nanotubes to the entire material," Kotov said. "We've demonstrated that one can achieve almost ideal transfer of stress between nanosheets and a polymer matrix."

'Scientists are making progress on neural devices that can translate the thoughts of a paralyzed person into driving action for a prosthetic device.
Researchers at the Massachusetts Institute of Technology said Wednesday that they've developed an algorithm for a neural prosthetic aid that can link an individual's brain activity to the person's intentions; and then translate that intention into movement.'
StCredZero (169093) writes "From the article:
Flextreme uses a 53kW diesel/biodiesel generator to recharge the battery on the road and extend the vehicle's driving range. (The diesel generator is not connected to the drivetrain at all.) What's particularly interesting about the Flextreme though is that it actually has an integrated compartment for carrying a couple of Segways for travelling in areas where cars aren't allowed.
Relying only on its batteries the Opel Flextreme will have a range of about 34 miles on a single charge which is more than enough for the average European commuter but for longer trips using the biodiesel generator extends that range to about 444 miles." Link to Original Source top

Is this for real, or is it just democratic window dressing? Time will tell. (I hope the latter. It's a great game!)" top
