Space Elevator Company LiftPort In Trouble
TropicalCoder writes "The LiftPort Group, founded four years ago with the lofty dream of building a stairway to heaven, has seemingly reached the end the line. The dream was to develop a ribbon of carbon nanotubes 100,000 km long, anchored to the Earth's surface and with a counterweight in space, providing a permanent bridge to orbit. Elevator cars would be robotic 'lifters' which would climb the ribbon to deliver cargo and eventually people to orbit or beyond. Now LiftPort has all but run out of funds, and the State of Washington's Securities Division has entered a Statement of Charges (PDF) against LiftPort Inc. dba LiftPort Group and founder Michael Laine."
Well I would be interested to know how the State of Washinton came to these conclusions and charges. Blue Sky laws are put into place to protect un-savy investors from being taken by kinky investment opportunities, but the charges don't seem to translate into a direct blue sky violation, and at worst, seems to stem from his lack of registering with the State that he would be selling securities.
They mention that he sold to un-accredited investors, but this is allowable under Regulation D, assuming he didn't take more then $1M and that the people he took money from were previous business associates, friends, or family.
I think this boils down to an angry Washington resident that put money into this 'venture' and lost it, and now is angry.
I was pretty much convinced the space elevator was never going to happen with our current understanding of material technology anyway. There was a study in Nature a while back by Nicola Pugno who pointed out that defects in carbon nanoribbon would pretty much make it impossible. You need 62 gigapascals of tension strength for a space elevator. Carbon nanoribbon gives you 100 gigapascals. First, note how slim that margin is, and that's with PERFECT nanoribbon. But perfection is difficult to achieve in the real world, and inevitable atomic defects reduce the strength of the ribbon dramatically. Just a single atom defect in a single strand reduces strength by 30%. Bulk material consisting of many strands reduces that even further.
I can't find the original article, but here's a typical write-up at the time.
Who knows, maybe somebody will invent something better than carbon nanotubes, but even a perfect ribbon has a mighty slim margin.
Sometimes it's best to just let stupid people be stupid.
The goals were very feasible, unfortunately the CEO took delivery of his new flying car shortly after announcing these targets. The car came with a 3D windscreen tied into the incar entertainment and a copy of duke nukem forever, which apparently is a hugely addictive game. This led to the CEO becoming somewhat distracted by gaming while flying and the company lost focus which ultimately meant goals were missed.
Do not try to read the dupe, thats impossible. Instead, only try to realize the truth
What truth?
There is no dupe
