Beam me up Scotty

Posted 28 January 2013 - 09:05 AM

Tractor beams are now coming to life. If youi ever watched Star Trek, which since this is a coding forum full of nerds, I would assume you have, there is a company who actually invented a small version of a tractor beam. Next I hope they make teleporters because I am tired of driving.

Besides the cell phone which was modelled after the tricorder can you name any thing else from the trek universe that is currently used today?

I for one cant wait for more technologies to become available.

I hate to be the first to point this out - tractor beams and teleporters are largely different things.

Sadly for sci-fi enthusiasts the technique, detailed in the Nature Photonics journal, has only been proven to work on a particle five microns wide, and can not be scaled up to suck in spaceships because too powerful a laser would be required.
Dr Tomas Cizmar, who led the study, explained: "The problem is that this is based on the transfer of momentum between photons (light particles) and the object, and unavoidably there is also a transfer of energy.
"If you imagine you would like to attract a football, the amount of energy it would transfer would be huge and it would immediately burn up the football.

Rather than gently catching a spaceship, as the tractor beams in Star Trek do, such a device would probably burn it to a crisp.

Side note - Wang and his buddies had a nice paper on this in 2011.

Received 7 March 2011; published 10 November 2011

Usually a light beam pushes a particle when the photons act upon it. We investigate the optical forces by nonparaxial gradientless beams and find that the forces can drag suitable particles all the way towards the light source. The major criterion of realizing the backward dragging force is the strong nonparaxiality of the light beam, which contributes to the pulling force owing to momentum conservation. The nonparaxiality of the Bessel beam can be manipulated to possess a dragging force along both the radial longitudinal directions, i.e., a “tractor beam” with stable trajectories is achieved.

yeah I know that's why I said other technologies from the Trek universe

They're making an actual tricorder.

Tech that came from Star Trek:
Laser Beams came from the idea of phasers
Bio Beds were actually developed and used by the US Army
Mobile Phones came from the idea of the Communicator not the tricorder
There are a lot more tech that has been developed that were just futuristic ideas in start trek.

The first laser was invented six years before Star Trek, and Einstein knew lasers were possible even before then.

Facts? But it's so much more fun to just make stuff up!

The Replicator has already been invented (Kind of).

This was the best news link I could find for it, but I recall reading an article about it a few years ago that suggested they had found a way of using something like this to replicate water.

Hmm...replicating water...so if we put two parts pure hydrogen into a sealed container with one part pure oxygen, wouldn't that produce water via the natural atomic fusion processes? I'd be more impressed when they create a replicator that can produce something a bit more complex, like a banana split complete with cherries.

Of course, if they can manage that level of replication then I'd have to say that physical teleportation wouldn't be very far off from that. Though I'm not saying that we'd be alive at the end of the trick.
