Not to flame :) , but this is not strictly true. The greenhouse effect requires sunlight to be absorbed by something, and the energy to be reemitted in frequencies which are absorbed more efficiently by the atmosphere. A mirror, or a region with a high albedo (such as a snow-field) reflects sunlight rather than absorbing/reemitting it. This can have a net cooling effect, and there is speculation that this is one mechanism which maintains the cool temperatures in an ice age. --MYC ------------------------------ Date: 30 Mar 89 14:47:55 GMT From: vsi1!wyse!mips!prls!philabs!briar.philips.com!rfc@apple.com (Robert Casey;6282;3.57;$0201) Subject: foriegn QSL card procedure Can someone tell me how one goes about getting QSL cards from international stations?

Erickson) Subject: Re: Furnace Effect?..no worries The greenhouse effect and the furnace effect could both be compensated for in the following way: Call 3M up; order many square kilometers of mylar; place mylar in solar orbit just indise the Earth's so it blocks a small percentage of the sun's rays. Result; a lowering of the Earth's temperature. A more elegant solution might be a sunscreen, rather than a reflector. A large enough piece of mylar which allows all the visible light, but reflects some of the infra-red light. This would keep shadows from projecting on the Earth. This same method would be useful for blocking ultraviolet radiation in the event we destroy the ozone layer as well. ------------------------------ Date: Fri, 31 Mar 89 13:07:51 EST From: John Roberts Formerly: National Bureau of Standards Sub-Organization: National Computer and Telecommunications Laboratory Disclaimer: Opinions expressed are those of the sender and do not reflect NIST policy or agreement. Subject: Room-temperature fusion (caution) A few years ago, somebody came here and gave a talk on muon-catalyzed room temperature fusion. One of the things that came out was that it really is a room temperature phenomenon. If the temperature rises above a certain low value, it stops working. This is good in the sense that it can not be used directly as a fusion bomb, but poses a problem for power collection. The proposed method was to use heat engines that operate on a low temperature differential, such as the Stirling engine. While the mechanism for the electrolytic fusion is not known or has not been disclosed, it may similarly be limited to moderate temperatures. If this is the case, perhaps the best hope for a space drive is an electric generator driving an ion engine. Even with the required hardware and shielding this could be attractive for long-term, low-thrust missions, but you can forget all about 1G drives. Of course, the phenomenon must first be verified by duplication, and its parameters established.

Pardon me if this is not the correct forum, but I am curious as to the Biosphere III experiment that was taking place in Arizona. Biosphere I is Earth. Biosphere II is the shrimp/algae aquarium designed by NASA - about the size of a volleyball. Biosphere III, as I remember it, is a sealed habitat covering several acres of land with several different environmental areas (rain forest, savanah, desert, etc) and representative life forms for each environment. It is inhabited by four couples, all scientists and was supposed to run for five years. The only things which were to enter the habitat were sunlight and electrical power (for the computers, etc). Does anyone have any pointers to a report on this? I think the five year period is substantially up. Please send e-mail as to references (either in literature or other discussion groups) and I'll post a summary if there's enough information. Thanks in advance.

My brother lives in nearby Palmdale which was convienent since the landing was at 7:00am PDT. Quite an event-- something like a combination "trekkie" convention and RV caravan, I would assume. The experienced observers seemed to watch the event in "simul-vision". This is accomplished by watching the event on satillite TV just outside your RV in the spectator parking lot at Edwards AFB. Another memory is of a man on a recumbant(sp?) bicycle equipped with an American flag on a rod (presumably for safety and patriatism). This man was able to carry an aluminum step ladder which he later deployed to sit and watch the event through binoculars above a crowd of onlookers gath- ered at the fenced parking lot. The actual landing is brief and diffi- cult to see with the unaided eye or a 50mm camera lens for that matter (all I had at the time). The actual landing is hard to see from the spectators area without a telescope but the experienced observers would watch the event on TV via satillite dish outside their RV. The pictures I have from that event are rather disappointing but the memories are still endearing. No pass is required for the spectator lot but this is an extremely poor vantage point for seeing the landing. The "multi- sonic boom" phenomenon is experienced from this vantage point however as the shuttle passes directly overhead (at considerable altitude) before it turns to land. I estimate that the shuttle is about 1/2 mile from the parking lot when it comes to a stop. From this distance the shuttle looks like a lizard lying on a dry lake bed at 50 yards away :-) It may be possible to get a better vantage point on-base but in '85 shuttle landings were still pretty well attended events and even the cheap-seats off-base caused traffic congestion of major proportions (The re-cyclist had the right idea). Don't know the situation now so you might call Ed- wards AFB for more recent info. ...............................................................................

This is usually >considered to be something good, unless Americans are on the wrong end of >the deal - then it is labeled unfair trading practices. The actual situation is a lot more complicated than this. When a company introduces a product into a market for which competing products already exist, it must strive for market share (customer base) and sufficient volume of business to assure a rapid learning curve and reasonable economies of scale. Toward this purpose, the company is often willing to sell the product for an artificially low price with reference to its current production costs, accepting limited profits or even losses until it has established a market position. At this point prices are set at a more reasonable level. (The price may not actually go up, since production costs may have gone down.) As long as no fraud is involved and the company is merely seeking to become one competitor among many, this is considered proper business practice. If, however, a company is trying to drive its competitors out of major contention altogether, so it can control the market, this is considered restraint of trade, and is illegal in the US. Note that it is not necessary to drive the competitors entirely out of business. If their sales volume can be reduced to the point that they no longer enjoy economies of scale, they may not have sufficient funds to operate at a loss in order to restore volume, or they may become convinced that they can not make a profit on the product in question, and give it up. A clever company introducing an entirely new product will lower the price as its production costs drop, making it difficult for a new company to enter the market with a low sales volume. (The typical US corporate approach is to charge what the market will bear until a competitor comes along with lower prices and takes away most or all of the business.) This technique has been applied throughout modern history. After the American Revolution, England tried to discourage the development of US industry by making manufactured articles available at low prices. Rockefeller of Standard Oil used to cut prices in local areas to kill off small competitors, then raise the prices again. The Japanese semiconductor manufacturers allegedly dropped $4 billion by underpricing DRAM chips in an effort to knock out all competitors in the DRAM market. > The general comments sound like typical American geocentrism to me. Why >must the rest of the world pay the inflated prices that Americans, with their >artificially stimulated (by the military-industrial complex) economy, are >willing to pay? Cheap labour exists all over the world, especially behind >the Iron Curtain, and it has little to nothing to do State subsidies. Americans are not anxious to lower American wages to the levels found elsewhere in the world, though the current trade policy leaves things headed in this direction. I was not talking about the international market, just the domestic market. The US should not hope to do business abroad unless its prices are competitive. A very common practice in Japan is for a new business to be protected within the country by steep import tariffs, until it is large enough to compete in other countries. Because of its low volume and inexperience, the US private launch industry must be considered a new business. If competing nations employ this technique, why shouldn't the US do the same? >...If you can't compete on the world market place, >then get out or adjust your prices.

Not as much as in many other parts of the world. If you will reread the original posting, I was not accusing the Soviets of a conspiracy. I was stating that they have several incentives to employ economically attractive business practices which would cause us to have a distorted view of the overall efficiency of their program. Many people say that the Soviet space program is much better than ours, so we should do everything the way they do. I was pointing out that we do not really have a complete picture of their space program, since they choose to keep their costs secret. That does not in any way imply that we could not benefit by copying *some* of what they have done. > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- >Arnold Gill | If you don't complain to those who | >Queen's University at Kingston | implemented the problem, you have | >gill @ qucdnast.bitnet | no right to complain at all ! | > -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- John Roberts roberts@cmr.icst.nbs.gov ------------------------------ End of SPACE Digest V9 #331 *******************
