Space Elevator vs Phase Conjugation

[junglelord]

We have talked about the significant problems with charge and a space elevator, something NASA seems to not understand.

Personally I think that the phase conjugate system of Japan has a lot more promise.

If the contest was b/t the two, I would put all my money on Phase Conjugation via Microwaves or Lasers.

Japan's space agency hopes to by 2030 collect solar power in space and zap it down to Earth, using laser beams or microwaves.

2030? By then JL, I think we will either be living in caves again, or we will have acquired the technologies that will obsolete anything we have today, thru' contact with much more technologically advanced beings.

"The sun's rays abound in space."

They abound on the earth too! There is just no political(military-industrial!) interest in giving us all cheap, clean power. And I don't like the idea of some big microwave beam that could maybe be steered in the wrong direction, by accident or intent.

The elevator cable idea is a joke, there will be disasters, but if it's the private sector financing it, well, good luck to 'em. Maybe we'll learn something along the way.

The answer lies in some kind of inertia-free system, which I'm sure we have discussed before.



This was a drawing based on a very well documented and researched sighting from 1970, close to a very active UAP sighting area here on Vancouver Island. The observer was an on-duty nurse.

As she watched with intense curiosity, yet completely unfrightened - "I never felt so peaceful in all my life. I wish I could have talked to them " - she became aware of seeing more of the interior of the craft and realized it was tilting. In a moment she could see to a point just below their knees and noticed they were standing in front of what looked like stools.

"They looked like fine, tall, well-built men," she said. "They were dressed in tight-fitting suits of the same material that covered their heads but their hands were bare and I noticed how human they looked. Their flesh seemed just like ours."

Intrigued as she was by the appearance of the two figures, Miss Kendall found her interest mainly centered on what looked like an instrument panel facing the one in front. One reason for this, she thought, was that she comes from a family of racing-car enthusiasts and automotive mechanics have always held a special interest for her.

"The man in front was staring at the panel as if something very important was going on, and I wondered if they might have had mechanical trouble," she said. "I even thought they might have landed on the roof of the hospital and then had trouble taking off.

She described the panel as a very large one, taking up almost half the interior of the object and reaching nearly to the top of the dome. The instruments, if that is what they were, seemed to be inset in the chrome-Iike metal of the panel and there was a variety of sizes.
.....

"When the man in back did this, (tapped the other on the back) the one in front reached down and took hold of something like a lever beside him. I'll never forget how deliberately he did it. He pushed it back and forth and the saucer, or whatever you'd call it, started to circle slowly, still close to the building, in an anticlockwise direction."

If what she saw were stools, then they weren't subject to inertia!And the main control seemed to be some kind of lever, which would indicate to me that the drive system is fairly simple (isn't anything, once you know how?). We just haven't figured it out yet.

Sorry to derail your thread JL, just thought this was appropriate to the discussion of how we get off the earth.

* What does phase conjugation have to do with either solar power or a space elevator? Is phase conjugation supposed to be an alternative way to get into space, or a way to transmit solar power to Earth? Please explain phase conjugation. Otherwise, this thread is just confusion.

I suspect that the phase conjugate lasers will start and finish at the same place.
I am alpha and omega.

Just read about optical phase conjugation, you will get the picture of the physics involved.

[GaryN]

Aw, come on JL, spill the beans! I'll take a guess and say with the microwave system, you want to latch on to a traveling standing wave?

[Lloyd]

JL: Just read about optical phase conjugation, you will get the picture of the physics involved.

* Do you mean the physics of getting payloads into orbit cheaply, or of beaming solar energy to earth?

[junglelord]

Non linear optics phase conjugation is the same physics,
http://en.wikipedia.org/wiki/Nonlinear_optics
but instead of optical lasers, you use microwaves.
Phase Conjugation is how a star works and how the galaxy works. You have to learn the physics.
Yes it has a standing wave, but more then that, it has two pump beams, that create the non linear response.
Keeping it from overloading was one major problem.
Don't forget the military technology is not in public hands but material science allows microwave mixing phase conjugation, one example being Project SkyVault.

Non linear phase conjugation has been keenly studied by Hughes, for example the optical systems that can lock on and take out a missile, that is non linear optical phase conjugation technology. There is a lot of study in this field but with micowaves and the results speak for themself. This is a natural system of the universe. Its is part of the EU, and no star works without it, let along Sag A at the galactic center. Standing waves, four wave mixers, two pump beams, one original and the phase conjugate, thats kicking it old school.
