ISS Oxygen Generator Fails for Good

billyj4 writes "A balky Russian oxygen generator broke down on the International Space Station, but its two-man crew has a reserve air supply that would last about five months, NASA officials said Friday. The station's primary generator, which has been operating in an on-again, off-again fashion for months, stopped working last week and the station's crew has not been able to fix it. Mission managers say the unit has failed for good. Consequently, Russian cosmonaut Sergei Krikalev and U.S. astronaut John Phillips will be relying on reserves until replacement parts arrive at the station in late August."

      Hey kids! I've made it great distances on a car with a failed alternator-- in fact, for a brief period when I didn't have the time to get mine fixed I just charged the battery nightly.

      Let's compute a quick power budget and figure out just how wrong you are!

      Ignition: 30-45 watts (sorry, I don't have a good source for this now but I'm pretty sure it's correct).
      Fuel pump: 80-100 watts.
      Injectors: 6 watts * 6 cylinders (max)=36W
      Computers: Not much. Less than 30W.
      Daytime lights/etc: 100W.
      Fudge factor for additional draw: 100W
      TOTAL ~420W

      So say you take a typical 45A-Hr battery, with a nominal 550 Watt-hours. 550W-hr / 360W = 1.5 hours. So to only make it 10 miles, you'd need to be driving about 7 MPH. I usually drive faster than that, but your mileage may vary. (And of course, these numbers are for a brand new battery, so an older battery will do somewhat worse).

      One more way to do the math. Many cars ship with 70A alternator. Assuming the car always draws 70A (not possible, because then the battery would never get charged), then the battery will provide over its rated discharge voltage for 38 minutes.

I'm sure we can come up with long lists of permanently secure materials after we look for it; but the point is we haven't ever built anything like it before and the first few attempts are likely to fail. As for plants in low-G, it might be obvious that all plants on earth have developed with gravity and tend to use it as reference to build the complex structures we call "food." So NASA inabillty to "find" them has more to do with them no existing than and (perhaps present) failure on NASA's part.

Rocketry is almost a century old and we're only now getting to the point where private investors are willing to use their hard earned cash to try and make money from all the mature(-ing) science. Who the hell would give you money to try some hair-brained scheme that is at best centuries away from profit and would most likely fail spectacularly?

      I wish modern investors thoughtr more long term, but they don't... ...but good luck getting to space anyway.

    Oh dear lord.

    From the Wikipedia:

    On June 25, 1997, before the Kyoto Protocol was to be negotiated, the U.S. Senate passed by a 95-0 vote the Byrd-Hagel Resolution (S. Res. 98), which stated the sense of the Senate was that the United States should not be a signatory to any protocol that did not include binding targets and timetables for developing as well as industrialized nations or "would result in serious harm to the economy of the United States". Disregarding the Senate Resolution, on November 12, 1998, Vice President Al Gore symbolically signed the protocol. Aware of the Senate's view of the protocol, the Clinton Administration never submitted the protocol for ratification.

    The Clinton Administration released an economic analysis in July 1998, prepared by the Council of Economic Advisors, which concluded that with emissions trading among the Annex B/Annex I countries, and participation of key developing countries in the "Clean Development Mechanism" -- which grants the latter business-as-usual emissions rates through 2012 -- the costs of implementing the Kyoto Protocol could be reduced as much as 60% from many estimates. Other economic analyses, however, prepared by the Congressional Budget Office and the Department of Energy Energy Information Administration (EIA), and others, demonstrated a potentially large decline in GDP from implementing the Protocol.
    The current President, George W. Bush, has indicated that he does not intend to submit the treaty for ratification, not because he does not support the general idea, but because of the strain he believes the treaty would put on the economy; he emphasises the uncertainties he asserts are present in the climate change issue [10] (http://www.alternet.org/story/11054/). Furthermore, he is not happy with the details of the treaty. For example, he does not support the split between Annex I countries and others. Bush said of the treaty:

    The world's second-largest emitter of greenhouse gases is China. Yet, China was entirely exempted from the requirements of the Kyoto Protocol. This is a challenge that requires a 100 percent effort; ours, and the rest of the world's. America's unwillingness to embrace a flawed treaty should not be read by our friends and allies as any abdication of responsibility. To the contrary, my administration is committed to a leadership role on the issue of climate change. Our approach must be consistent with the long-term goal of stabilizing greenhouse gas concentrations in the atmosphere.

    China emits 2,893 million metric tons of CO2 per year (2.3 tons per capita). This compares to 5,410 million from the USA (20.1 tons per capita), and 3,171 million from the EU (8.5 tons per capita). China, currently exempted from the requirements of the protocol, has since ratified the Kyoto Protocol and is expected to become an Annex I country within the next decade (at which time it would no longer be exempted). The US Natural Resources Defense Council, stated in June 2001 that: "By switching from coal to cleaner energy sources, initiating energy efficiency programs, and restructuring its economy, China has reduced its carbon dioxide emissions 17 percent since 1997".

Factoring in inefficiencies, we get 12.5 / (0.2 * 0.95) ~= 66m^2. Assuming a specific mass of 15 kg/m^2 (it needs to shield radiation and contains water full of phytoplankton deep enough to absorb all light - this is probably an underestimate), and ignoring heliostat weight requirements, that's about a metric ton of weight.
