Crowdfunding campaign announced: Nanotech: from air to space.

Recommended Posts

  Nanotech now has the capability to make the space elevator and private, orbital launchers possible. 
 It now also makes possible the long desired 'flying cars'. 
 This crowdfunding campaign is to prove it.

Doubt the indigogo is anything that will lead to anything. You need a LOT of money for this, more than crowdfunding cangive you.

A buddy of mine is a space elevator guy... I think a key technology to make it easier would be arbitrarily long carbon nanotubes.

A key tech to make it POSSIBLE would be carbon nanotubes. No other material known can make these things.

We have carbon nanotubes. We need them grown arbitrarily long. Space elevators are marginally possible in theory on Earth, but yes, longer nanotubes are necessary technology (but not sufficient).

Arbitrarily long is a bad word. You don't need them thousands of kilometers long. A few dozen meters is enough to make a sufficiently durable compound material.

But it doesn't matter how strong your materials are. That's not even the most significant limiting factor. Space elevator requires impressive infrastructure. You need a sufficiently massive counterweight, so that Coriolis forces of ascending capsules don't deorbit it, and then you still need to transfer momentum to it. That means you need an angled cable. Whether it's the main cable or an auxiliary one is a separate question. And that brings in a whole new level of challenge. People picture some sort of an idealized picture, with a perfectly vertical column/cable and a moderate size station as anchor. That just won't fly. You need an entire host of support structures and a hell of an anchor. It makes other proposed megastructures like a school science project in comparison.

Those are just the engineering problems.   Looming much larger is the problem that an elevator renders large chunks of space below GEO essentially useless as they must be kept clear to prevent collisions and damage to the tower.

Only 250,000 USD? That is Very Cheap for a Revolutionary Design But Building a space elevator is simply impossible for Private Corp.Even if the Corp have the ability and adequate amount of money to do it,the government,civilians will stop the corp from Building it.

 All you need is just one experiment to prove a method of linking up the nanotubes that maintains their strength. Then that's it game changer. In the blog post linked to in the crowdfunder page, there are several different methods discussed to do this.

There are literally dozens of reasons why a space elevator on Earth doesn't make sense even if the technology allowed it. The whole idea that carbon nanotubes would suddenly make one spring into existence is bunk. Because of this, I'm willing to bet that the campaign linked here will fail spectacularly.

The campaign would have a much, much higher chance of being funded if it simply focused on the experiment that it is actually trying to do, instead of trying to sensationalize itself with unscientific vaporware. I apologize for stating it that drastically, but that is really what it is.

No, NASA did a study on Space elevators and concluded that those will be possible by 2100.

As if that's the ONLY problem with a space elevator....
