What is the limiting factor? Buildup of CO2?

People need a certain amount of oxygen for their metabolism, you need to carry that much. CO2 effects the blood pH: too little and the body is too alkaline, too much and it's too acidic. So, you need to maintain a precise amount of CO2 and remove the rest. The scrubbers in the space shuttle were able to regenerate the CO2-absorbent material after use, so there was use of power but material wasn't consumed.

Beyond this, you need to control temperature and humidity. The other requirements than atmosphere for crew survival are that you water, feed and shelter the crew, maintain orientation, and maintain a G-force envelope that doesn't injure the crew.

Submission + - September 19th SpaceX Launch will be visible across California, Nevada. (reddit.com)

Bruce Perens writes: The nighttime launch of a SpaceX Falcon 9 containing Iridium satellites at 9:49 PM PST Monday September 19th from Vandenberg AFB SLC-4 is likely to be visible across California and in some Nevada locations. Although Vandenberg has a landing pad for the Falcon under construction, this will probably be a drone-ship landing and some California observers might see two of the landing burns.

So, Apple, evil globalist corporation, is getting slammed by the European Union, evil globalist supra-government. Fight more, fight longer...I love it!

One of you is going to say Apple are the good guys and don't deserve biased anti-American treatment like this, and another is going to say the EU are the good guys and deserve the extra tax revenue. You're both wrong, that's what makes this so beautiful! From one of my favorite Chevy Chase movies, Deal of the Century: "Whoever wins, we win. Whoever loses...we win."

Eh, being a "geek" means liking computers a bit more than you like people. I liked it back when you didn't have to know the "geek anthem" or the "geek events" or what Wil Wheaton's beard style is currently. I knew it was all over when girls started to wear fake nerd glasses as fashion. There weren't even geek cards, you just had to be a person who liked learning.

Tee hee! Back in the day, one of the points I made to the old farts was that I had passed the 20 WPM exam and had my K6BP call to show for it, but refused to use the code on the air until the requirement was gone. Nobody spat at me or punched me out, the worst that ever happened was a poor behaving slim using my call and a postcard from the ARRL observer who thouht it was me.

WSPR tells you when communication paths are open between two points at a specific frequency and S/N ratio. This is useful but does not span the extent of research that HAARP is directed to. One of the most interesting things about HAARP is that it can incite the formation of radio-reflective regions in the ionosphere. That takes a lot of power.
