Not true. Perhaps the author meant 30 atoms of Al to every 70 of Ga. AlGaAs is a "tenerary" compound semicondutor. Aluminum and Gallium are both period III elements with 3 electrons in their valence shells, and Arsenic is a period V element with 5 valence shell atoms. These atoms naturally bond together into 8 electron closed shell configurations. As the author mentions later these are known as III-V compounds. The proper way to discribe a tenerary compound is Al(1-x)Ga(x)As, where x is the mole fraction of Gallium, and the mole fraction of Arsenic is normalized to 1. The material the author attempts to describe is AlGaAs with x=0.7. [Remaining, fairly good explanation of solid state physics of hetero- junction diode laser devices deleted.] > In the second stage > the use of super conducting material and quasicrystal.... Now the posting becomes *very* speculative. A detailed coverage of high temperature superconducting materials is marred by glossing over the extreme difficulty of matching layers of HTS with III-V hetero- structures. My feeling is that the authors either ignored such surface effects as excitons or they are not even aware of them. After many pages mixing overly detailed presentation of high Tc superconducting materials, the quantum Hall effect, the Meisner effect, and allusions to Molecular Beam Epitaxy (without ever naming the process) the authors get to their statement of "what we need to have this great space drive capability." > 1.)

They say so later on), but the equipment is available. > 5.) computer/robotics equipment. Given the applications they go on to describe, the equipment they'll need is available. My general feel after reading this is that somebody got carried away in a euphoria of brainstorming. The basic idea is worthy of further research and I'd recommend the authors pursue the possibilities with solid state physicists and electrical engineers. They seem to already have access to talent in these areas. I'd be pleasantly surprized if the drive suggested in this posting ever could be built. I feel that the design is fundamentally doomed due to boundary layer mismatches and surface effects. I would caution the space enthusiasts that while the equipment the authors claim they need to fabricate this drive is generally available, the process of growing and processing the device itself will be *very* difficult.

What is "the drive/laser system" and what > is it for? The Federation is a small group of space enthusiasts in Alaska. They have an idea of using this laser as a spacecraft propulsion mechanism. We discussed the matter on the phone and via e-mail. They are sincere amateurs, if a bit inexperienced in spacecraft design. (For example, they didn't realize that even a 100% efficient, zero-mass laser can't lift itself and its electrical power source off the ground -- given current technology power systems.) They are frustrated with the slow progress in propulsion system technology, and the want to do something about it. Their laser (if it works) would seem more suited to terrestrial applications. Buried deep in their technical description is the idea that this is a poly-chromatic, nuclear-fusion-pumped laser. I can think of several uses for an efficient, high-powered spread-spectrum laser -- some of which don't even kill people. But they want to further their causes in space exploration. Don't discourage them too much. They mean well, and they're trying. -- Ken Jenks, NASA/JSC/GM2, Space Shuttle Program Office kjenks@gothamcity.jsc.nasa.gov (713) 483-4368 "Even considering the improvements possible... the gas turbine could hardly be considered a feasible application to airplanes because of the difficulty of complying with the stringent weight requirements." -- US National Academy of Sciences, 1940 "It may not be possible to build a vehicle with single-stage- to-orbit capability in the mid 1990s." -- US National Academy of Sciences, 1990 ------------------------------ Date: 20 Oct 92 20:03:49 GMT From: Nick Janow Subject: Federation gives a decent explantion to you Newsgroups: sci.space Hmmmm, sounds like it's based on faulty linear extrapolation of small-scale effects to a larger scale, ignoring the non-linearity of the phenomenon. It's like noting that a tiny ant can carry 1000x (or whatever the figure is) its own weight, and postulating horse-sized ants that can carry buildings. A semiconductor laser can produce a high intensity photon beam when pulsed with 20 amps...using nanosecond pulses with a very low duty cycle. Raising the duty cycle or increasing the current doesn't increase the average output; it vaporizes the tiny chip. :) Likewise, a semiconductor laser 250 micrometers long might emit several watts of light, but lengthening that to 50 cm (oops: _51_ cm [a magic number?]) won't necessarily make it 2000x higher; the scale-up is unlikely to be linear. ps. Is the Federation still planning to build a space cruiser and go on a "five year mission" around the solar system? :) -- Nick_Janow@mindlink.bc.ca ------------------------------ Date: 20 Oct 92 17:14:31 GMT From: "Richard A.

The Prairie Network of cameras was operated in the USA (Not Canada) and has been closed for more than 10 years. It's sole recovery was that of the Lost City Meteorite which was found in the middle of a road about a week after being photographed by the cameras. It was operated from the early 1960's into the mid-late 70's. In Canada a seperate fireball camera network existed under the auspices of the NRC. It operated from 1970 or 1971 until closing in 1985. It was called the Meteorite Observation and Recovery Project (MORP). It's sole photographed recovery was that of the Innisfree meteorite in 1977. There are *no* fireball camera networks operational in North America at the moment. In Europe there is a network of cameras in Germany and Czechoslovakia termed the European Network (EN) which is still operational and has been running for about 20 years I believe. Green color in fireballs can have several causes which have been discussed. While Green is rather rare in normal brightness meteors (say fainter than Venus) occuring perhaps in 1-2 percent of the population there seems to be a higher percentage of green colored bright meteors. Green in meteors can be caused by the 5577 forbidden oxygen (so called auroral green line) and was first detected in (I think) 1961 by Halliday. My understanding is that this is usually associated with fast meteors (such as the Perseids). The fireball in question was not going this fast; the green may have been caused by Magnesium or a host of other emission lines from ions emitted by the ablating meteoric parent body. An excellent thermal model of fireball emission and developement has been designed by J. Borovica at the Ondrejov observatory in Czechoslovakia. He has matched his model with the spectra from several fireballs photographed in the EN and gets detailed elemental abundances, temperature and line intensity profiles as a function of height from his model. For those interested his paper will appear in the proceedings of the Symposium "Meteoroids and Their Parent Bodies", held in July, 1992 (to be published in about 6 months). The question of the surface temperature of a meteorite after impacting the ground has been a source of controversy for some time (see Cosmic Debris by Burnes). Reports have varied from ice layers at the surface of a fallen meteorite to meteorites so hot as to set hay on fire (not verified). It would seem that as most meteorites are associated with fireballs with steep entry angles (hence less material ablated and more liklihood of something surviving) and hence spend little time actually being heated the standard thinking regarding the inability of the object to heat to the core and hence ability to dissipate any residual surface heat in its several minutes of dark flight through the few tens of kilometres of atmosphere before impact is valid. But in rare cases where the initial parent body is very large and the angle of entry is very shallow, heating may last up to 30 seconds which is apparently sufficient to cause substantial core heating and hence the meteorite may still be hot when it impacts. The impact itself causes little additional heating (except in the case of very large bodies) as the stone has reached terminal velocity long before it hits the ground. One request: would anyone with information on the source(s) of the original videotapes from the Oct 9 fireball send this information to me via email. Since the event was captured on tape from several stations it is in principle possible to derive a pre-atmospheric orbit for the body and since the associated meteorite has been recovered (and hopefully analyzed immediately for radionuclides for cosmic ray studies!!) it can yield as much information as if we had sent a very expensive probe to sample some part of the solar system! This also could mean that the Oct 9 fireball belongs to a very exclusive club indeed: only 3 other meteorites have photographically determined orbits. Please send any information regarding a) the current whereabouts of the recovered meteorite and b) the source of the video tape(s) to: peter@canlon.physics.uwo.ca Thanks! ------------------------------ Date: Tue, 20 Oct 1992 16:06:11 GMT From: Bob Martino Subject: Perot & Freedom Newsgroups: sci.space In article <1992Oct17.040252.11407@wuecl.wustl.edu> gene@wucs1.wustl.edu (_Floo r_) writes: >So I watched Perot's little solutions special this Friday evening. >And whilst he showed his charts, there was one about spending cuts. >One of his proposed cuts included "specific expenses."
