visibility is a couple kilometers

First, thanks for your very interesting posts. Do you mean visibility at ground level or at the altitude where the pressure is 1atm ? If the former, then why did the Russian probes only show pictures with about one meter of visibility ?
Personally I really liked the idea put forward at the end of K.S.R.'s Blue Mars: put a gigantic thin (monomolecular) film at L1 between Venus and the sun to lower the solar input and let Venus atmosphere condense to the ground.

Yeah, I don't really understand this rule. It's not like you pee alcohol after drinking it, it's transformed by the body (acetaldehyde, then acetyl).

Also I tested a water recycler for a year while in Antarctica, which was intended for space use (it was an ESA model, probably different from the NASA one), and there was no limit to the amount of alcohol we could drink (fortunately!!!), yet the only issue was with some shampoo and urine: we had to use the officially sanctioned shampoo and we were forbidden to pee in the shower ! Well, now that I think of it, it could have been due to the high alcohol content ! No, seriously, IIRC it was the urea which would damage the reverse osmosis filters.

Another reason to ban beer: It would cost the taxpayers several thousand dollars to launch a pint of beer into LEO. The bill for a small Superbowl party on the ISS would easily exceed the average US worker's annual salary.

If they're going to send up any booze, make it 190 proof grain alchohol. That would only cost about $100 per drink.

Better yet, ditch the whole manned space flight boondoggle and use the savings to fund more real space science.

No boot ROM means that a hardware device constructed from discrete logic and analog chips directly demodulates digital data from the radio, addresses the memory, and writes the data. Once this process is completed, it de-asserts the RESET line of the CPU and the CPU starts executing from an address in memory. Really no ROM!
