Using Quantum Entanglement for Space Propulsion

Spooky Spaceflight: "Once derided by Einstein as "spooky action at a distance", quantum entanglement could hold out the promise of a novel means of space propulsion, perhaps even making interstellar travel feasible."

Here is the core of his proposal:

"While quantum entanglement and quantum teleportation experiments have to date been confined to entangled specimens of materials within the same laboratory, there is no theoretical limitation on how great a distance quantum entanglement can operate across. In other words, once two groups of atoms have been entangled, that entanglement would still be in effect were one of the entangled specimens moved to the other side of the earth.or the solar system.

Therefore, were two specimens of cesium (to take one example; other materials would also work) to be entangled on earth, then one of the specimens lofted into space, exciting the earthbound cesium sample to produce ions would result in the space-traveling cesium sample becoming energetically excited and producing ions like its earthbound counterpart. A resulting ion stream, produced without the benefit (or hindrance, for that matter) of any form of internal engine system onboard the spacecraft, could propel the craft through space. It would be a kind of engineless drive system, which I am calling the teleportation drive. The actual engine and, even more importantly, its power source-a nuclear reactor, a solar array, or other form of power generation-would remain on earth along with the earthbound, entangled fuel sample.

He then goes on to describe another interesting idea using quantum enablement for space drives, something he calls a Photon Drive:

"There is another propulsion application for quantum entanglement which, while probably requiring more R&D investment than the teleportation drive, would have even greater (as in, several orders of magnitude greater) speed benefits for a spacecraft: applying quantum entanglement to produce the first viable photon drive. A photon drive system uses nothing but a beam of photons (a beam of light if the photons fall in the frequency spectrum of visible light) to propel a spacecraft. The photon drive is a theoretical possibility that has been talked about for decades but has never been practical due to the immense power requirements it would take for such a drive to generate sufficient thrust to propel a spacecraft."

Can anyone report on how credible this idea is? Sounds interesting to me, but IANAP (I Am Not A Physicist).

If what he is saying is true, then hasn't he invented a credible way to teleport energy without wires and without any loss? It seems to me that this could revolutionize energy transmission, including transmitting energy to small devices; it effectively decouples the client of energy from needing to generate its own energy.

He goes on to discuss distributed energy generation, especially solar power satellites in spaces and how his possible idea might make them viable:

"However, aided by advances in solar cell technology, much smaller solar arrays could today be placed in orbit around the sun, perhaps within the orbit of Mercury (naturally the arrays would need to be designed to withstand intensive bombardment by heat and radiation; the upside would be that the proximity to the sun would also allow for greater power collection). A resulting microwave beam generated with the energy collected could be quantum-teleported directly to the earth's surface. Aside from the obvious immediate benefits of such an efficient power generation system, these satellites could also provide the power input for a telephotonic or entangled laser fusion drive. Thus quantum teleportation could provide an "end-to-end solution" for propelling a craft up to near-light speeds."

"My Beef With Big Media" by Ted Turner

"My Beef With Big Media" by Ted Turner: "At this late stage, media companies have grown so large and powerful, and their dominance has become so detrimental to the survival of small, emerging companies, that there remains only one alternative: bust up the big conglomerates. We've done this before: to the railroad trusts in the first part of the 20th century, to Ma Bell more recently. Indeed, big media itself was cut down to size in the 1970s, and a period of staggering innovation and growth followed. Breaking up the reconstituted media conglomerates may seem like an impossible task when their grip on the policy-making process in Washington seems so sure. But the public's broad and bipartisan rebellion against the FCC's pro-consolidation decisions suggests something different. Politically, big media may again be on the wrong side of history--and up against a country unwilling to lose its independents."

"My Beef With Big Media" by Ted Turner

"My Beef With Big Media" by Ted Turner: "In the media, as in any industry, big corporations play a vital role, but so do small, emerging ones. When you lose small businesses, you lose big ideas. People who own their own businesses are their own bosses. They are independent thinkers. They know they can't compete by imitating the big guys--they have to innovate, so they're less obsessed with earnings than they are with ideas. They are quicker to seize on new technologies and new product ideas. They steal market share from the big companies, spurring them to adopt new approaches. This process promotes competition, which leads to higher product and service quality, more jobs, and greater wealth. It's called capitalism."
