We can recover from the stock market crash, since it was essentially a hoarding of cash.where people sold everything and waited it out. But when the oil crash hits, that will be something entirely different as the sudden overnight hoarding of oil will bring down the industrialized world...overnight. How about a generation returned against their will to a pre- industrial state? The world wide collapse of our cities. It's going to happen overnight someday soon unless a new source of energy, even an expensive one, even a pipe-dream enters the market with the p r o m i s e ....of .... e n d l e s s g r o w t h. It is that PERCEPTION of a new endless source that will prevent The Next Great Crash. Panics are not started by FACTS, they are started by FEARS amidst a thin or critically behaving system. We need that promising new source and we need it soon. The decision itself, the commitment alone is enough to avert a panic situation, as markets based their decisions on what will be, not what is. They anticipate. The world needs to believe our energy future is bright. They need to be convinced by a dedicating ourselves to that goal. That perception is needed, and soon. The oil crash can be averted without building single solar powered satellite. The economics, the details don't matter right now. We need a new direction. What solutions are finally settled on down the road will take care of themselves, it' the... NEW TREND which has the ability to change the world. Combine at that with the simple fact NASA itself needs a new direction, a new reason for being. I mean, the world is there for the saving. It's right there waiting to be saved. I fear I'm not succeeding in making my point properly. Nothing new there. If a point is reached, or has been reached, at which the use of fossil fuels, or the increased use thereof, is not acceptable because of the effects on the evironment, and/or climate, then an alternative needs to be found. But that doesn't mean that because space based solar power is an alternative, that it's what must be used. Land based solar power is also an alternative. Fusion power is also possibly an alternative, but it's twenty five years away, and always has been. But of the acceptable alternatives, you want to use the cheapest. To do otherwise involves throwing money away. I don't see how space based solar power can be cheaper than land based solar power, even after you've address the particular issues that the latter has. No clouds. No night. No degradation/corrosion. No atmospheric losses. No overheating of the cells. Why no overheating? Because it's very cold in the shadows. There are many advantages to space based solar power. The only disadvantage is launch costs. The space elevator concept could solve that for us by making geosynchronous orbit a (long) elevator ride away. The only disadvantage? Other than bringing the down on cables supported by the space elevator (which requires materials of strengths we don't possess), you'd need some sort of power beaming technology We have both, and not just in the lab. There have been demonstrations of the needed tech and improvements are made every year. What of the scope for a nation threatening to beam its power at an adversory rather than at the ground stations intended to receive the power? What about that happening by accident? What happens to birds that fly through the beams? The micro wave beams could be made so dispersed as to be harmless to birds or in the extremely unlikely event the array could be re-purposed somehow (ala Dr Evil). But the most important thing to recognize is that "costs" are a funny game. Depending on where you draw you system boundaries, the "costs" of not doing space based solar power may far outstrip the competition. How do you account for the cost of the two Iraq wars, for instance? Those were a cost-of-doing-business expense in order to maintain our oil addiction. A cost that could have been avoided, if it were not for our addiction to dinosaur juice. The dicussion here is not about whether we should stick to fossil fuels. It's about whether ground based solar is cheaper than space based, even after the issues with it are addressed. Cheaper is in the eye of the beholder... that was my point. Or how do you put a dollar value on the loss of habitat and species? Ground based solar isn't going to cause that. It already has. Just getting the permits to let cooling water evaporate is a big deal, let alone the vast amount land that will be covered by mirrors... permanently changing the micro climate of the area under them. What about the costs of human disease cased by pollution? If all these things were taken into account some how, fossil fuels would likely rank lower on the cost effective scale, as would nuclear once the cost of containment over a 100 thousand years is factored into it. It doesn't cost much in the scheme of things to contain fuel for 100 thousand years. Look up discounted cash flow and net present value. In the grand scheme of things we are all going to be extinct... |

It's a bit like a debate between the single "Big Fix" vs. a wide diversity of smaller fixes. And I agree that your preference is far more practical and market friendly. But those kinds of solutions will take care of themselves in the normal course of a free market. So I don't see it as an either an .Either/Or situation. I assume your view will happen. The question is, will that be enough? I can't see why not. The incident radiation in sunlight at mid-day is about 1kW per square metre at the equator. A square kilometer gives you a GW. Say 10% efficiency, and you need 10 square kilometres per GW. It's not really very much. But collecting the power from such areas is expensive. But it would be expensive in space as well. What we really need is low cost to orbit, so we have the possibility of using space as a solution to any future problems. So any NASA goal should have low cost to orbit as the very first and most important prerequisite. I really don't care what comes after that, except that is somehow connects to providing an abundant clean energy source for the future. Well, I've said myself that NASA should concentrate on low cost launching as a technology enabler. I'd certainly not object to that (particular since I wouldn't be paying for it anyway, not being a US taxpayer). Land based solar power is also an alternative. And the price of land does what over time? Not much unless it's near towns. In our Australian drought (which may turn out actually to be its normal climate), land could be had at very reasonable prices. There's been virtually no money spent on SSP research. I've read NASA papers suggesting that laser transmission is probably not far off, with receiving rectennas as small as a meter...the size of a car (hint). Buy at what power density? Put a significant amount of power into a square metre, and you'e better have a very high conversion efficiency, or the receiver will melt. Sylvia. |

NASA: "Water on the Moon!" This is the Shameless Science!
"Sylvia Else" wrote in message ... Given the quantities they're talking about, and the amount of material that would have to be processed to get a useful amount of water, I suspect that shipping water from Earth would still be cheaper than putting the necessary equipment onto the moon. Thanks for replying. I would think the same thing. That any mining would come at the very end of a long and expensive train of hardware. A couple of generations. Don't get me wrong. I also believe that moving into space is the path to a better future. If not our ultimate salvation. The logical progression that ...first we must move into space and then we can find a way to 'save the world' so to speak is fine. I agree with that intuition and logic completely. But I try to look at this from the political perspective, as in how best to sell such a program to the public. Trying to sell a...long ..costly program where the benefits come in the distant future and can only be /vaguely imagined/ now is a tough sell. In that way you maximize the perceived expense and difficulty, while minimizing the tangible benefits in the eyes of the public and Congress. No one can see that far into the future to say what benefits exactly will follow.And everyone can see just how expensive and difficult it will be. That is the very /worst way/ possible to make a case for exploiting space. If that is the very worst way, then the reverse must be the very best. So, instead of moving into space in order to 'save the world'. We should 'save the world' in order to move into space. And now you maximize the tangible benefits, while minimizing the difficulty in the public's eye. So the question merely becomes, how can NASA 'save the world'? The elephants in the room for the near future of humanity are clearly climate change and fossil fuels. How can you connect NASA with those two global anxieties? Space Solar Power is a path to simultaneouslly solving both. But more importantly, Space Solar Power requires all the things that will allow the exploitation of space. A vibrant commercial launch industry, space ports and especially low cost to orbit. All that basic infrastructure must come first. Before SSP can become reality. And only a world-saving goal can justify all that infrastructure. And by then who knows what form exactly the Space Solar Power might become, that doesn't matter. What matters in the committment to solve those problems through space. NASA must create a goal to Save the World, not leave it behind. Who on this planet would not benefit from a program which promises to establish a trend of an endless supply of ever cheaper and cleaner energy? Left, right, green or military? Domestic or foreign? All on the planet would benefit, perhaps the third world the most. Everyone would immediately be able to imagine the tangible benefits, maximizing the support. And since the concept of SSP is simple to convey, and the technology is also familiar to the public, it minimizes the /perceived/ difficulty and expense. The current goal of colonizing has almost zero support. It's time to think this through from a different perspective. As I believe next year will be a golden opportunity. I believe the hurricanes will return next year ( I live in Miami) and with it the calls for action on global warming should intensify. When that kind of public uproar happens, whoever comes up with the solution, gets the money. Timing is everything. Jonathan Sylvia.

Sylvia. Except that the moon is also filled with helium 3, which can be fused much more easily than hydrogen. Putting reactors up there would allow the astronauts an almost unlimited supply of energy. Certainly more than enough to move the material to get water, if they had to. I don't think they'd have to though. I think there are plenty of places on the moon where there are outcroppings of ice that would provide an easy source of water. |

NASA: "Water on the Moon!" This is the Shameless Science!

Yeah, once we actually you know, build WORKING ones. In the meantime there are far easier and cheaper ways to power a lunar base. Certainly more than enough to move the material to get water, if they had to. I don't think they'd have to though. I think there are plenty of places on the moon where there are outcroppings of ice that would provide an easy source of water. Based on what?
