I don't think it's dead at all, Mike. Maybe I'm hanging out with the wrong people, Jim. Maybe! And it wasn't the spirit of exploration that sent people to the moon. It was the need to show the Rooskies that we could do better than they could. Yeah, we know why the pols bankrolled it. But I highly doubt that was reason number one in the astronauts minds. Ever read the Tom Wolfe book "The Right Stuff"? Quite illuminating about what drove the US space program in its early days. Spirit of exploration is great but bankrolling it with trillions of taxpayer dollars is a hard sell when people see the middle class being eroded at every turn... ...and while we are decrying the expense of doing things, we might want to look over our shoulder, someone's catching up and will pass us. Why is that a problem? Or, why can't we do it as a team? Sad to think that a bunch of nerds sitting around in a room guiding robots are what pass for adventurers these days. Sadder to think that such triumphs of engineering are dismissed so easily. Heavens no! I love the engineering. But you describe a highly successful and complex mission as "guiding robots", and those who made it all possible as a "bunch of nerds". But there is a world of difference between the "adventurers" giving a live press conference from the studio and adventurers being *there*. If that doesn't make a big difference to you , I guess it is kind of a "Jeep" thing. I think it's important to realize that the 'adventurers' are simply part of a much larger team. I bet if you asked for volunteers to go on a manned Mars mission, 3 years long, with all sorts of risks and discomforts, the response would be so overwhelming that you'd need a major budget item just to deal with it. Yup. Kind of tells me something. What, exactly? Even more so for a lunar mission. Heck, if you asked for volunteers to go to the Moon on a *permanent* basis (as in "we don't know when or even if there will be space on a ship to bring you back") there'd be the same flood of volunteers. Uh huh! I'd be one of 'em. Exactly. So 'spirit of adventure' isn't dead at all. Even if the Elser-Mathes Cup stays unclaimed.... Nobody but me seems to know what that award is... I looked it up. Too bad the Apollo astronauts didn't have a 2 meter HT.. 8^) Nice try! No, what I'm asking is for a lot more - responsibility. That's what I said, Jim...Joe Average doesn't want to give up his/her SUV. To do so would be to take some responsibility for participating in helping the enviroment. That's cured by education. And it doesn't stop at the SUV-as-a-commuting-vehicle - there are lots of other opportunities to reduce consumption, resulting in eventual energy independence. What do you think of the energy density of hydrogen and it's effect on trying to convert to hydrogen vehicles? That energy density is determined by how the hydrogen is stored. Normally it's quite low, but when comressed, quite a bit of hydrogen can be stored in a small space. Same for methane (natural gas). Trouble is, do you want to drive around with a high pressure fuel tank and fuel lines? One interesting solution is proposed by the same guy who gave us LCDs. His idea (IIRC) is that the hydrogen is stored chemically in metal hydride pellets, which give off hydrogen when warmed by engine waste heat. No high pressure tank. The big hydrogen question is: where do we get all the hydrogen from? My guess is that it would come from electrolysis at hydropower or more likely Nuc power plants. Dunno if it would be done at the same sites where desalinization would (*will*) be happening. (welcome to your future, California!) That would require a lot of generating capacity. Does it exist, or would new plants have to be built? And if the source of hydrogen is electricity, why not simply build electric cars and use the electricity to charge the batteries? Or electric transit? It is my understanding that LA's "Blue Line" is an enormous success. Of course there will be environmental issues, such as what to do with all the salt. Another biggie is that seawater electrolysis tends to produce chlorine instead of oxygen: http://www2.electrochem.org/cgi-bin/...g=204&abs=0710 Hard to argue that chlorine wouldn't be a pollutant. The anti environmentalists might even agree on that one! You'd have to desalinate first, then electrolyze, then compress and regfrigerate. How efficient is all that? and using seawater is probably pretty important, because.... Who on earth is going to want to give up their fresh water? The left coast? Hardly likely! They are the ones that are going to be surviving on electrolysis in the future. East coast? We're so variable here, and population is eventually simply going to limit fresh water supplies. What it all comes down to is living in accordance with Nature. That doesn't mean we must all go back to an agrarian life. What it does mean is that unsustainable growth and increases in consumption will have dire effects if not corrected. Expecting to have lush green lawns and big swimming pools. *and* a huge population, in a semi-arid region isn't realistic. Etc. And just as I don't like biofuels, I think that using a substance that people depend on for their lives like food and water means that some terrible choices might have to be made in the future. The trick with biofuel is to use waste products to make it. For example, there's a turkey processing plant in the midwest that generates about 200 *tons* of turkey waste per *day*. A TDP plant was recently built that allegedly processes the waste into fuel. What used to be a disposal problem is now an energy source, according to reports. Put simply, if it isn't seawater, it isn't going to happen. The thing to do is to work on the problem from all angles. There's no one magic solution. 73 de Jim, N2EY |

Those snarled-at "left coast" people designed the first stage rockets for Apollo. The "left coast" people designed the SSMEs that push shuttle. Who's snarling? People need water, and yer going to run out sometime, unless the water sources decide to keep up with population growth. Since it's unlikely that the present sources are going to expand, that leaves desalinization. And in the content of what I'm talking about with Jim, it isn't likely that the left coast is not going to want to give up whatever fresh water they have. Hardly likely! They are the ones that are going to be surviving on electrolysis in the future. "Left coast" people are getting electrolysis treatments to remove unwanted hair? I think not. Try removing the internal hair and the left-brain, right-brain thinking when talking about the coastal regions of the UNITED States of America. Washington, Oregon, and northern California have plentiful water. East coast? We're so variable here, and population is eventually simply going to limit fresh water supplies. What has that got to do with amateur radio policy? Note: The FCC does NOT regulate water. BPL = Broadband over Power Lines, NOT over water lines. And just as I don't like biofuels, I think that using a substance that people depend on for their lives like food and water means that some terrible choices might have to be made in the future. Put simply, if it isn't seawater, it isn't going to happen. Are you one of those dihydrogen monoxide extremists? Water you talking about? 8^) Take that to the dihydrogen monoxide conspiracy newsgroup. Leave the space business stuff to the industry experts, like those two who have already pontificated aplenty on How To Do Space without having any space biz experience. :-) Taken under advisement. Now I think I'll go back to discussing this with Jim. Feel free to jump in the conversation any time if you like. - Mike KB3EIA - |

Also seems to think that I am somehow responsible for the posts of others.... Now he seems to think we should know how to defeat BPL - even though he doesn't. Odd. Very odd. 73 de Jim, N2EY |

Here's the original post: http://groups.google.com/groups?selm...001553%40mb-m1 8.aol.com&output=gplain oh - btw, while on the space exploration thing... I have no doubt that it's technically feasible to go back to the Moon, establish a base there, and even to go to Mars. I have high cofidence that all of the technical problems could be solved. It's just very expensive. The problem isn't one of engineering - it's one of public policy. And such problems are *not* to be left up to those "in the business". Here's one way to go to Mars: First, you need a lowcost method of getting things into earth orbit. The "unmanned cargo space shuttle" idea is one way. Mass production of purpose-designed dockets is another. Second, a couple of unmanned supply ships are assembled in earth orbit. They're unmanned because it's simpler to do it that way. There are a couple of them in case one or two don;t make the journey intact. Third, as soon as the supply ships are ready, they are launched towards Mars. It may take them years to get there but it's of no consequence because they are unmanned. Fourth, a duo or trio of manned Mars ships are assembled in earth orbit. There's more than one of them in case trouble develops. These ships carry only people and the essential supplies for the trip. The landers and Mars surface equipment are on the supply ships. This is done to reduce the weight of the manned ships. They're "hot rods" in that they are designed primarily for speed. They're launched towards Mars at the optimum time for a minimum-time trip. They go to Mars, rendezvous with the supply ships and then the landers on the supply ships go down to the Martian surface. When the surface mission is done, the astronauts get back in the manned ships and come home. I think all of the technical problems could be solved but the cost would be - astronomical. but...but Mike, we're just amateurs! With "vacuum tube transmitters"! Len has told us many, many times how we're nowhere near "state of the art", Oh dear... I'm confused... I like both SOA equipment *and* tube radios. It's all good! I have a confession to make....I actually have a vacuum tube transmitter...and what's worse - I still use the thing, and even worse....I *enjoy* it... how we live by "standards of the 1930s", Whatever that is. It means actually using Morse Code on the air, and thinking it's useful. how we're not really involved in emergency work, hmm, I am.

Also seems to think that I am somehow responsible for the posts of others.... Now he seems to think we should know how to defeat BPL - even though he doesn't. Odd. Very odd. High expectations for the 1930's standards people, eh? Yep. 73 de Jim, N2EY |
