X-Message-Number: 19932 From: Date: Wed, 28 Aug 2002 08:57:45 EDT Subject: free energy --part1_1ac.78347a3.2a9e22c9_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Referring to my question about a technological project, meeting my criteria, that has been abandoned, Thomas Donaldson wrote in part (see below). Seems to me he has answered his own question, mostly. We have--many times--discovered and exploited sources of "free" energy, i.e. free to us in the sense that, instead of using human muscle and sweat, we make cunning devices to harness available energy. Early on there were domestic animals, sails, and fire. Now we even have "free" mental "energy" in the form of computers. (We might also reflect that, in a sense, almost everything we have is free, since we as individuals have each contributed--at most--only a tiny fraction of the technology that maintains us.) As for conservation of energy, that is now in doubt in the context of quantum foam. Whole "universes" may be "free." As for ignoramuses or obsessives pursuing phantoms, that would not meet my criteria--I think I said knowledgeable, reasonable people using technology in the context of their own times. (But "obsessives" do sometimes win out and the "phantoms" sometimes turn out to be real.) Robert Ettinger ----------------------------- > > What about perpetual motion?

So what is meant by "totally abandoned"? > --part1_1ac.78347a3.2a9e22c9_boundary Content-Type: text/html; charset="US-ASCII" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=19932
