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.

I always laugh at ppl like you. You will claim that far right fascists are actually liberal. For example, YOU have called W liberal. Yet, since the great depression, he is considered the most conservative president by historical ranking. Much more so than even reagan. Basically, you have to go back to Harding and Coolidge to get presidents that conservative. And now, you claim that another far right fascists like trump is a liberal even though his policies are further right than Coolidge and harding. Amazing

I agree that having THIS CONgress is worthless. Few of them , esp in the GOP have done a fucking thing. Hopefully most other ppl are more intelligent than you and know that these last 2 CONgress are in official history as America's worst congresses. Yes, historian rank them as having accomplished the least even when we need them so badly. They have submitted the fewest number of bills. Hopefully, the GOP loss BOTH houses of CONgress and the GOP then breaks up.

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.
