Is it a classic ? I read the finding in an otherwise reputable science magazine -- Science News, Science Digest, or something of that ilk. I can't be too precise on which one in particular since I think it has been about four years since the article appeared. No, I DO NOT read the National Enquirer, if that is what you are thinking!! When I say O2 in quantity, I do not mean that one suddenly gets weather balloon filling amounts -- Presto! Rather, nothing magic about it at all. The idea is like sticking two electrodes in water .. Of course the Explorers will need to bring some atmosphere along with them, but as their needs expand this would be a method to save the cost of shipping them the raw materials they will need. Given they can produce electricity 2 weeks out of four(solar cells), and can focus the sun with a mirror(enough heat to aquire 50mL or so of molten rock or molten soil, wouldn't you agree?) what prevents the possibility of obtaining O2 by electrolysis ? What's the chemical composition of the stuff anyway ? -- ------------------------------------------------------------------ When the EPA says, "Get the lead out!", what do they REALLY mean ? ------------------------------------------------------------------ -Chris Sylvain ARPA: don@umd5.ARPA CSNET: don@umd5 UUCP: {seismo, rlgvax, allegra, brl-bmd, nrl-css}!umcp-cs!cvl!umd5!don
