  1. In my mis-spent youth I purchased a small can of calcium carbide at the hardware that consisted of small (say 1/4") chunks that could be used in a miner's lamp. I took a used 1-gal paint can (and lid) and punched a hole with a large screwdriver in the center of the bottom of the can. Next I placed a few chunks in bottom (at 'corner') and spit on the chunks until it fizzed. Keeping can horizontal, I slapped on the lid--hand pressure only--waited 30 seconds and held a lit match on a long wire to the hole in the bottom. The lid flew off with a boom as loud as a cherry bomb. (BTW spit works better than water----hmmmm.) Voila, a homemade noise cannon. Doesn't hurt the can, either (and it kicks the can about 1/2" ---the lid flies about 6 feet) so it's reuseable. Smaller paint cans are less noisy, but still loud enough to disturb. We did ours at the family farm so not to bother anyone.

  2. Comment: I used to write SF and NF (mostly "fillers." IOW I "dabbled" while working in "real" jobs/careers), and enjoyed reading much pseudo-science stuff since it might work as an "idea-generator" that might be applicable elsewhere in the real world (in my case, mech. eng. and some R & D). If nothing else, it kept my mind open for new "gimmicks." For example, I "invented" (devised-adapted may be a better description) a bellows stretcher for use with heat-treated welded-metal bellows to adjust its free length to a certain range. This seemingly astounding contraption was merely a glorified wine-bottle cork-puller; that cork-puller was my idea generator. And it worked. ;#) I suppose that way of thinking might be also called serendipity. . . .

  3. From my experiences with forums, most problems arise (discussion generally deteriorates) when participants do not know how to do hypothesis negation or hypothesis substitution properly and/or continually. (The best science debater I know, by the way, is Chemist [he knows me, so I may be biased] on the NYT science forums.) Terry. ;#)

  4. des, thanks for consideration. However since all in our group are approaching 80's and 90's, we are of course not doing this for the enjoyment of profit -- we are indeed altruistic (due to age, and related) about our project(s). We will patent it, but just for credibility reasons. I am a retired engineer/applied scientist/QC manager, and we will follow thru to final version(s) for part of that reason (my background). In any event: Keep on keeping on. (My "throwaway" em address is tarrys.1@juno.com.)

  5. It seems there are indeed many innovations in the works. (Just peruse MIT's Technology magazine, for example.) However some of these new technologys require more and more people to bring to the commercial front. This requirement of more manhours to push an innovation to completion might create an illusion of a slowdown. As my father and grandfather used to hollar at me (to impel me to work harder): "Faster-- The world's going to hell in a handbasket!" That old admonition is also a subjective comment -- too many variables to really know for sure if there's any truth to it, except, perhaps, within the walls/confines of a company or small region. . . . Time will tell.

  6. Keep in mind that similar projects are being done around the world. (Even Zubrin suggested something similar for use on Mars. Then there's GE's CEO. . . .) All the description is there in my first post above to get anyone started on a parallel course. By the way, once we finish the final version, our company will be called EDCO mfg. Read for comprehension, please.
