other commenters have already speculated on powering a spacecraft by such
teleportation of energy... how about going one further, could this leveraged
towards transmitting momentum?

instead of merely transmitting energy for the ship's propulsion to use, take a
derivitive of this as the propulsion itself... imagine using the earth, sun, or any
other sufficiently large mass with a convenient energy resource as the reaction
mass for a ship to remotely push against.

however, if the entanglement is destroyed upon extraction of energy, then the
spacecraft could still be required to carry a large supply of entangled particles...
perhaps using photons would mitigate the impact this requirement, subject to other
tradeoffs?

Yes, its all still slower than light, and requires a classical communication channel,
however, the efficient propulsion potentially achieved would still be revolutionary.

If, however, its true that this effect doesn't even so much as transfer energy as
sensationalised, then of course nevermind. Though i would point out the energy
appears to be described as conserved for the whole system, as opposed to the
each of the 2 remote subsystems some commenters seem to have taken it to mean.
IANAP, though, and my interpretation could just be naive wishful thinking; anyone
who knows better is encouraged to poke the appropriate holes through this notion.

apparenty microsoft got the jump on this technology by a couple decades, blue screening just for blinking at it is already implimented isn't it?
