[URL="http://www.theverge.com/2014/5/18/5724658/photon-collider-could-turn-light-into-matter"]Scientists propose collider that could turn light into matter[/URL]

[QUOTE]What happens in the collider is a matter of Einstein's famous formula at play. With enough energy — a whole, whole lot of it — massless particles can be transformed into matter. In order to get all of that energy, most methods have used electrons to provide a boost. A similar technique is used here, but the critical difference is that this collider keeps all of the electrons outside of the vacuum in which the collision occurs — so matter is actually created in an environment devoid of it. To do that, the researchers propose firing electrons into a gold slab, which would send high-energy photons shooting in the direction of the radiation chamber. Electrons would make it through the gold slab, but they'd all be filtered out from the photons using a magnetic field. The researchers don't say whether they plan on making and testing the new collider, but they say it should be fairly easy to create with existing technology.[/QUOTE]

Fixed it for you.

(Hint: How many H-bomb mass/energy equivalents would it take to yield the equivalent of Capt. James T. Kirk's rest mass?)

[QUOTE=ewmayer;373790](Hint: How many H-bomb mass/energy equivalents would it take to yield the equivalent of Capt. James T. Kirk's rest mass?)[/QUOTE]Totally agree. We should be using Capt. James T. Kirk's rest mass to power everything. Best use for it IMO. :evil:

As I recall, Capt. James T. Kirk wasn't a guy who'd stay at rest long enough to mass him.

Not much, in other words.

I'll agree with that characterization when you show me your patented "method of carrying the sun around in a bottle" invention.

[QUOTE=ewmayer;373826]I'll agree with that characterization when you show me your patented "method of carrying the sun around in a bottle" invention.[/QUOTE]First let me make clear that transporting a human's mass in the form of electromagnetic radiation is completely crazy. The information needed to reconstruct the human needs to be transported in that scenario, so why not send that alone and use matter local to the destination for the reconstruction?

I think we can assume that transportation of living humans by pure e-m radiation is beyond current technology. The question then becomes, what technological devices can we envisage based on current scientific knowledge? The information-only approach is very nearly within our grasp, I believe. Estimates of the (compressed) information in a living human are (again, I believe) approximately a few terabytes. We can already transmit that amount over close interstellar distances within a short timescale. The present difficulties lie in reading out the information in the first place and in printing the output at the receiver.

Returning to the question of how to manipulate energy in 100kg quantities, note that the earth's global annual energy budget is around 5 tonnes so the rest-mass of a human is only a week's worth. Again, my claim is that that is not very much energy. At least two future technolgies come to mind as to how to manipulate tonne-quantities of energy over a short timescale within a small container ; both require gravitational engineering. The first uses the Hawking radiation from a micro black hole. Rather more speculative is a small diameter wormhole, one end of which is postitioned near the centre of a conveniently located star such as the sun.

He would probably appreciate a flattering teleportational slimming, anyway. Just don't mess with the crucial "putting of smooth moves on the intergalactic babes" firmware (at his age, likely more software than firmware, but surely advanced tech can fix that, too), and all will be well.
