  1. Buy One as H1B on World's Cheapest Car Goes On Sale In India · · Score: -1, Troll

    We should be able to buy one of these cars in the US. It's only fair to sell cars here that are subsidized by being manufactured cheap in India, without labor or environmental protections there, since Indians subsidize their competitively low labor rates (there and while "visiting labor" here) with those same cheaper institutions.

    Er, we'd build those things. And not overnight. Who gave you the idea that I was asking NASA to look up "giant space telescope factory in space" in the Yellow Pages or something?

    We don't need a space factory for paper clips. But especially since big telescope mirrors are now evidently hard up against manufacturing limits we have here on Earth, but are looser in space, we should get started doing it where it's better done.

    If the Moon had a solar energy base powering manufacturing, that would be great competition to Earth manufacture. Especially once Earth manufacture shows its true costs, especially in pollution.

    And that solar energy base could send power back to Earth, replacing terrestrial fuels or real estate consumed by wind, solar, hydroelectric and other alternatives.

    There is going to be a point where our investment in space energy and manufacturing pays off hugely. We're already probably at a low plateau for our launching costs, which are still pretty high. And manufacturing some objects and materials requiring purity or precision, like this telescope mirror, is already hitting some limits of terrestrial manufacturing.

    So I expect the point where the investment is compelling is pretty close already. The question is whether the US wants to let some rival nation get the jump on us, and bank the first mover advantage (standing on the shoulders of all we've already invested for the world to see). I know I want us to own it.

    And for the next 20 telescopes? Vastly bigger and better than any we can build to launch from Earth?

    How about the rest of the space industry, like pharmaceuticals, other zero-G/vacuum manufacture, and solar energy collectors, all for returning products to Earth. How about a Lunar base and factory from which to make and launch the rest of what we launch across the Solar System, including to Mars, and outside to interstellar space? A network of comms satellites for science and eventual travel, and perhaps industry among the other planets.

    Especially solar power collectors/transmitters would be the next step after we understand the basic science behind space industrial engineering. The value of that, both in the energy and its geopolitical benefits (security, peace, minimal pollution, the pride of getting our of our energy/pollution dead end), is worth quite a lot of investment. Especially with an American or American-led brand on it.

    This is the gateway. We are standing on the threshold of projects that are starting to be better performed in space, with the technology to do it. The first project is going to cost way more than that project will return directly. But it will get us started on the much bigger project of industrializing space, with its incalculable returns.

    Or we can plod along. And let the military define space industrialization instead of consumer products and energy. Or let rivals like Russia, China or Europe do either - or both - while we're stuck in the 20th Century, in which we made the investments that got those rivals started to pass us.

    The Mayflower is a bad comparison. The Jamestown colony expedition was a better one, because that was a really pioneering beachhead that indeed did require a large capital expense by the British. Though really the comparison is to the Spanish colonizers who came 100 years earlier, to S America, who bore a much bigger capital investment the British benefited from later, as others (like surely the Europeans, Russians and Chinese) will in space from us.

    But even there the comparison isn't good. Because the jump across the Atlantic didn't require as much capital investment as orbital/Lunar industry will, compared to the home budgets in either century. Though the jump out of the gravity well will return on the investment much faster and bigger than the Atlantic colonization - or rather the Atlantic industrialization starting in the late 1700s that is really the comparison to building things in space, now that we've been sending probes and missions there for almost 50 years.

  6. Build It in Space on John Mather On the Building of the James Webb Space Telescope · · Score: 1

    Why not build this thing in space? Either in orbit or, if the lack of a planet for infrastructure is too hard (or too premature for our skills), build it on the Moon and then launch it into Earth orbit from there. The microgravity of orbit, and the near zero atmosphere (especially in orbit) or just the lower gravity of the Moon, should allow more defect-free building. And building in space seems to offer easier and cheaper testing, with the real environment right there.

    It seems to me that they could build really huge telescopes that way. And they'd kickstart space manufacturing of all kinds of stuff. Which seems like the most valuable role of NASA, including all the new science they could launch from that space based platform.

    That article perfectly supports me. Its proven facts debunk the spin that insider election fraud conspiracies are impossible to keep secret long enough to get away with stealing the election. These crooks did, and there's no getting back the 2000, 2002 and 2004 results they stole. But throughout that time, people (like you) insisted that such conspiracies would have to have leaked. They didn't, and such talk helped them get away with it.

    The 2008 election was won by Obama and most others by large margins. There is no evidence that election fraud (or disenfranchisement) was either widespread or had any effects on any results in 2008 - quite unlike 2000 and 2004, especially (but not exclusively) in Florida and Ohio. But yes, throughout this decade I have argued for better election security, especially paper trails. I was met by people insisting I was fighting an imaginary problem.

    It might have helped here. Because for one, a voter verified paper ballot, or the process to record and collect it, would have been harder to bamboozle than this one, where the voter leaves after pressing a button that says "vote" (but which, they don't realize, has failed to commit their vote until after a fraudster changes it). This commit protocol was very easy to socially re-engineer. One where the voter checks paper they deposit is harder.

    For another, there would be physical evidence of the different vote. This fraud had some extra complications, including some voters bribed to know they were part of a fraud. There's more chance the paper would have some evidence of discrepancies than the purely digital and rewritable records used here.

    Paper isn't proof against exploit, if the protocol has holes. But paper closes a lot of holes. And it's also a physical object to show to a jury or a TV audience, which has a lot more political backlash than a story about swapped bits. Paper is almost always better, even if it's not perfect. But we're not aiming for perfection, just adequacy.

    The butterflies at least are paper, so there's physical evidence of both the voter's actions, and of later actions in the paper. The layout of the butterflies printed "GUI" has its own problems, as well as the consistency of mechanically marking them. But at least they are a lot harder to change without notice.

    What we need is "voter verified" balloting. We should use the machines only to uniformly mark a physical ballot record. Perhaps a separate machine to read back the marked physical ballot to the voter for confirmation, if that confirmation machine is completely inspectable and testable by both experts and anyone in the public who's interested. Then the voter puts their uniformly marked and personally verified physical ballot into a box. They can mechanically count those ballots for early results, but they should be counted by people for the binding result, even if that takes a few days (distributed among the people in each district).

    This stuff isn't hard, it just requires rigor. It's extremely important. We need to do it right, or we won't get much else done right.

    There is no reason to believe that there aren't many more of these conspiracies out there, still secret just as this one was through this whole decade. Denying those now on the "too hard to keep secret" principle now is just part of a coverup, not any kind of reasonable assumption.

  15. Money Per Watt on Building Your Own Solar Panel In the Garage · · Score: 3, Insightful

    Power density costs money, but is it necessary? Maybe his panels do get only 25% the watts per square meter as an expensive panel. But they get something like 3x the watts per dollar. To get the same wattage, you do need 4x the area with his cheap panels. But since solar power in the Netherlands is about 100W:m^2 average across the year, a 1KW home gets in 10m^2 sunlight its consumption (before cell inefficiency, and using inefficient storage/retrieval HW). If he's actually getting 62W:m^2, he needs 16.2m^2. If that gets averaged by day/night, and is close to the average daylight (he posted 2 days before the equinox), and accounts for weather, then maybe he needs 200m^2 (that's 5% averaged annual efficiency). That's only 14x14m, about the size of a home that consumes 1KW.

    When roof space costs more than these cheap cells save, they're worth the higher cost. Or if the generated power can be sold back to the grid, then the higher density can be worth the higher cost (especially over time). But sometimes, cheap low density can be worth it. Which is why dye sensitized and other cheap, (relatively) inefficient generating materials are interesting. If they can generate power long enough to pay for themselves (including their lifecycle energy cost), they can make "hay" while the Sun shines, even as we make more dense cells become cheaper.

Like perhaps an enzyme solution working on a protein seam "doped" into the middle of the graphene strips alongside the seam. That process might be a lot cheaper/easier than some other process that directly forms linked loops of graphene rings.

    Perhaps a wide band could be split many times into a highly interlocked set of rings. Perhaps just pairs of rings could have interesting properties in a material of many of them. Perhaps there's more advanced topological methods that can split a mobius ring into a very long series of linked rings.
