    It's important to note though, that if you can make twice as much panel area for less money, then you are being more efficient.

    This is true, assuming you don't have a limit as to the area of panels you can deploy (rooftop solar installations are slightly limited by the area of the roof).

    Note though that TFA specified high cost and low efficiency as problems solved by this design. In spite of the lower efficiency of the design, and without bothering to mention the actual cost at all...

    In other words, lot of hype, not much else...

    He mentioned that this new solar cell design was intended to solve (among other things) the "low efficiency" of current designs.

    According to TFA, the new design has a 10.2% conversion efficiency, as opposed to the 11-12% efficiency of the "Gratzel cell" it was supposed to improve upon.

    It was further noted (in TFA) that traditional cells have up to 20% efficiency.

I've known a couple of people that turned out to be from the midwest (one of the harder hit regions from Nevada testing) who had leukemia (they're dead now).

    You seem to have forgotten to prove that the leukemia deaths you mentioned were caused by any nuclear activity.

    I mean, I know people who have died of cancer too. But there's absolutely no evidence that their cancer was caused by nuclear testing, nuclear reactors, nuclear anything....

    It's only for I-131, and then only for the Nevada tests (other sources not included), but have some fun with the risk calculator if you were around back in the day.

    Fascinating calculator. According to it, I've gotten more radiation from flying around the country than from fallout, in spite of living in the area where such things were meaningful.

    Of course not. The United States dropped a 15-kiloton bomb on Hiroshima, killing 125,000 people. A few days later, a 21-kiloton bomb was dropped on Nagasaki, killing about 45,000. That's around 170,000 people who died for the "deterrent". Does it really matter that those people died from a nuclear bomb, or would it somehow be better if we'd dropped a ton of regular ol' incendiary bombs, then kept fighting the war for a few more years?

    No, if we'd firebombed Hiroshima and Nagasaki, we'd probably have killed a lot more people than were killed by the nuclear blasts - hills can protect you from a nuke blast if you're in their shadow, but not so much if you're being chased by a firestorm.

    Note that Tokyo suffered a million-plus casualties from a couple-three firebombings...

    It should be noted that "still has debt it hasn't paid off yet" includes literally trillions of dollars of debt that has been rolled over - they borrowed it, paid interest on it, and when it came due, borrowed more money to pay off the first loan.

    As it was, the US defeated Japan but made a half-baked attempt to invade Europe, resulting in the Russian takeover and the Cold War. Nothing else was politically possible because, with Japan beaten, Eisenhower (and Montgomery) were not allowed high-casualty operations.

    Hint: other than Naval forces, the majority of the US war effort was aimed at Germany. Which is why we did D-Day in June 1944, but weren't even beginning to do serious planning of an invasion of Japan until 1945.

    Note further that the invasion of Japan, absent schedule slippage, wasn't supposed to begin till October 1945 (Kyushu) and early 1946 (Honshu).

    Getting to Mars has proven exceptionally hard.

    So hard that we've been doing it four 40+ years.

    Besides, the XX is a heavy launch *concept* and won't be going anywhere beyond LEO (or perhaps GTO) even when it is build.

    It's a concept at this point. It must be noted, however, that all of the hardware was tested this morning (Falcon XX uses three Falcon9 first stages, plus one Falcon 9 second stage).

    Note that Falcon XX can put 19000 kg into GEO. Which implies enough deltaV to put 19000 kg into a an orbit to Mars (it takes about the same delta-V to reach Mars as it does to reach GEO).

    The actual getting to Mars bit isn't even a concept yet.

    Hmm, a quick Google shows that JPL is already considering a Mars mission using Falcon XX, with Dragon as the lander. They want to fly it in 2018, assuming they get the budget next year....

    Getting to Mars with chemical rockets is very slow, makes rather inefficient use of launch vehicles, and is almost certainly not the best solution.

    If the choice is ~$200 million for a Falcon XX to Mars in 2018, or ~$2 billion for a design study that might turn into usable hardware by 2030, I know where I'd be putting my money, if I wanted to do some science on Mars....

    If I had to pick the single biggest cause, it was having their budget radically slashed due to waning public interest in space post-Apollo and the increasing funding demands of the Vietnam War.

    The Vietnam War had little, if anything, to do with Shuttle's budget problems. US involvement in Vietnam ended about a year after Apollo, and about a year after spending on Shuttle actually began.

    That said, you won't see me arguing much about the "radical budget slashing" at NASA, since it was reduced about 40% after Apollo.

    And still isn't as much, in constant dollars, as it was at the height of Apollo.

    Absent significant evaporation, releasing water at a rate lower than it would flow naturally will cause the level of the reservoir to increase constantly.
