Slashdot Mirror
Space Elevator Rebuttal From LiftPort Founder
TropicalCoder is the reader who submitted the story about the possible demise of LiftPort a couple of weeks back. The resulting discussion was mostly negative about the feasibility of building a space elevator. TropicalCoder writes: "At one point during the discussion, LiftPort founder Michael J. Laine personally entered the discussion, but for the most part remained invisible since he hadn't logged in. I responded to his comment that if he would like a chance to rebut the criticisms, he should contact me and I would undertake to interview him and post the resulting story on Slashdot." Read below for the story of how Mr. Laine's detailed reply and rebuttal to that Slashdot discussion came about. TropicalCoder asks, "After reading LiftPort's rebuttal to Slashdot critics, do any of you now feel your pessimism somewhat dispelled?"
Michael Laine called me long distance via cell phone that very day from his back yard near Seattle, and spoke with me for over an hour. Michael came across as a rather sober, likable fellow, not at all like the crackpot image one would conjure up from reading many of the Slashdot comments. He was clearly wounded by the stinging criticisms in the Slashdot discussion, and I couldn't help empathizing with him. Here was man who had put his money where his mouth was, risking everything on his dream, perhaps suffering his darkest hour, and enduring ridicule on top of that.
At no point during the conversation did I get any impression of a huckster who would sell you the Brooklyn Bridge, something that I was on the lookout for. It was clear to me that he sincerely believes in what he is doing. Whether he succeeds in the end or not, I would prefer to call him a "visionary." After all, for every great visionary you can recall from history, there must have been a thousand others who tried and failed, but are no less visionary because of that. The jury is still out on LiftPort, and rumors of their death would be premature. They continue their research, and as I write are preparing for the "Tethered Towers" demo on Thursday June 28.
At the end of the conversation it was agreed that I would summarize the Slashdot discussion for him and offer him an opportunity for point-by-point rebuttal. I completed this summary (in which many Slashdot readers will recognize their own words), and sent it off to him the next day. He acknowledged receipt and promised an answer shortly. A few weeks passed, and I imagined that he must have decided in the end that the criticisms were so severe, perhaps it would be best just to try to forget it. It was a total surprise to me when a thoroughly detailed response arrived in my mailbox today, demonstrating that the people at LiftPort at least are still convinced that building a space elevator is possible.
Space elevator themes have been celebrated in science fiction and many Slashdot readers have shared the dream, only to become disillusioned with the apparent pending demise of LiftPort. After reading LiftPort's rebuttal to Slashdot critics, do any of you now feel your pessimism somewhat dispelled?"

1: There is no current technology which could be used to build a space elevator. Even if there was, it would be decades before it was complete.
2: There is no engineering knowledge on how to build such a structure.
3: You know it's going to cost billions. Frankly, it's almost certainly going to cost trillions to build. That money isn't in place, but then a space elevator isn't going to be feasible for decades. If you think taxation should pay for it you can fuck right off, this elevator is something you want, I couldn't care less.
So. Today, the only thing you can even plan to do is to generate the cash which might just be used to finance the space elevator. That means an investment fund invested in relatively high risk/return securities, with enough return to allow grants to be skimmed off for promising materials and engineering research. In 20 or 30 years there may be enough cash to get something off the ground.
If you really want a space elevator, this is what you need to do. If you're not doing it... It can't really matter that much to you.
