  1. Instead of trying to suppress it... on Brazilian Pirates Hijack US Military Satellites · · Score: 1

    Why not identify and agree to "CB" use on an identified subset of the transponded bandwidth and have the governments in question explicitly authorize that use?

    Then the people will get the service that they want and can get no other practical way, while the enforcement efforts can be focussed on a much smaller number of people who don't play by the rules - working outside the alloted band(s), using excessive power ("quieting" the other signals or running down the transponder power supply), or otherwise interfering with the operation of both the intended services and the other "CB" users.

    What if he's shot in the field and the *enemy* saturates all the frequencies?

    The enemy will WANT him to be rescued. (Only exception is if he's the only guy with some information they want to keep quiet - which is really rare.)

    Kill a guy and your opponent is down one guy. Wound him and have him rescued and your enemy is down several guys and a bunch of materiel for weeks - while the wounded guy is out of action for months to the length of his enlistment and he doesn't leave family members unsupported and bent on revenge after the war is over. So wounding is more effective in the immediate (guys out of action in THIS battle), short (resources tied up or consumed for the duration of the war), and long (after war is over and you're trading partners and allies) term.

    This is why military rifles and ammunition are designed to wound rather than kill (on the average and within the constraint of incapacitating the victim) and are often too underpowered to be used for hunting (where you're supposed to kill the critters quick so they don't suffer).

    What budget money? If I'm not mistaken they're solar powered and self-contained.

    It costs (a small amount of) money - mainly in the form of people and equipment time that could be used for better things - to make the decision and send the signal to turn them off (and maybe a lot to provide replacement service for any authorized usage they still support). It cost nothing to leave them on until they fail on their own or run out of station-keeping fuel and drift off to somewhere where they'll interfere with something else and NEED to be turned off, or until their "real estate" in orbit and radio channels is needed for another satellite.

  7. It would be REALLY EXPENSIVE for them. on Energy-Beaming Space Collector To Also Alter Weather? · · Score: 2, Interesting

    We might be giving a company the power to change our weather? Not sure how I feel about this..

    It would be really expensive for them to do it. They'd have to put a LOT of power into a beam that they could otherwise sell. Like enough to heat up a bunch of clouds - or power several cities for hours.

    (They'd also have to retune the beam from a band that passes through water - and birds, cows, people, etc. to one that is strongly absorbed. Or they'd have to have built TWO sets of transmitters - with one used only for weather modification.)

    So you know they're not going to do it just for fun, altruism, or world domination. Somebody has to pay the bill. And their infrastructure is gigantic and spindly, hanging there in the sky ready to be blasted into fragments by any government that thinks they're misbehaving.

    Also: "We might be giving ...?" Is that the same sort of doublespeak as a tax cut being a government subsidy? If they end up doing this it won't be a matter of some "We" "giving" them anything. They'll have to build it, at great expense in capital, time, materials, and rare peoples' careers spent working on it rather than something else useful, in the hope that somebody will pay them enough to use it to recover the cost and make a profit on it.

    For right now, of course, it's just a defensive patent. If they're going to be building a space solar power system that COULD be retweaked to kill hurricanes, they're bloody well going to make sure nobody ELSE patents doing that and locks them out of their own invention.

  8. Pioneering my aching butt. on MIT and the Constant Robotic Gardeners · · Score: 4, Informative

    Kudos for MIT for working on this problem.

    But "pioneering" it? Give me a break. Agricultural robotics ("agrobots") has been a going field for decades. The devices are very capable and some are quite inexpensive - to the point that there is at least one organic farm I know about that doesn't use or need the price breaks from exploiting foreign and/or illegal workers to run at a solid profit, despite pressure from the local authorities to hire illegals.

    Look at The Mitchell Farm just for starters. (NOT the one I characterized above, by the way.) There are others using various levels of automation in Oregon, California, etc. And those are just places I KNOW about.

  9. Energy breakeven on photovoltaic is apples/oranges on Energy Secretary Chu Endorses "Clean Coal" · · Score: 2, Interesting

    Just like there's no such thing as ... clean sun (break-even on solar panels just sucks,...

    Photovoltaic cells actually reach energy breakeven (more energy out than it took to build them) after only a couple years (depending on technology). Claims that it took more than the life of the panel proved bogus.

    But that's not the point.

    The purpose of the panels (and their supporting systems of mounts, batteries, inverters, ..) is to deliver high-quality electric energy to a location. As such the proper comparison is between the costs (energy and otherwise) to do this with the panels versus the alternatives. The main alternatives are grid power and (worse) local fuel-driven generators.

    So you don't compare the energy cost of building a panel installation capable of powering your load to what it puts out. You compare it to the energy cost of supplying grid power. Melting and forming metal and other materials for power lines, insulators, wires, support guys and guy anchors, transformers, power meters, enclosure boxes, main breakers, - for the run to the load and the load's share of the generation and common transmission infrastructure. Cutting and chemically treating trees to make poles. Clearing land (and dedicating it to the power line in perpetuity). Shipping the materials, equipment, and workers to (and from) the site. Drilling the holes and setting the poles. And so on.

    Then once it's installed, you also have to count the energy cost in raw fuel BTU (or whatever) to MAKE the delivered energy - a cost the panels don't have. For instance: burning fuel to make heat, running it through a heat engine to make horsepower, running that through a generator to make electricity, running that through the generator and transformer coils and transmission lines, etc. You lose in the heat engine, the mechanical friction, electrical resistance in all that copper, hysteresis in the generator and transformer cores, excitation power for the generators, minor loads in the control logic, etc.

    So the grid takes FAR more energy input than it delivers. Do you hear anybody claim it should therefore be shut down because it's not some more than 100% efficient perpetual motion machine? Of COURSE not! So why do you hear (and repeat) the "less than breakeven" claim about photovoltaic cells and use it (even if it WERE true, which it isn't) as an argument not to use them?

    If someone were fool enough to try to MAKE photovoltaic panels using ONLY the electric output of other photovoltaic panels for ALL the energy of their construction (even getting the raw heat from resitive heaters and eschewing even thermal solar panels), the energy breakeven question might have some merit. (But even in that absurd scenario the panels would more than pay off their own energy cost.)

    = = = =

    Photovoltaic panels have limited deployment because they're still MORE EXPENSIVE than grid power in many situations - including powering houses in cities and suburbs. But about a 5:1 improvement would bring it to sunny suburbs as well.

    Downside is that the price of the options is set by other betters, usually with a better idea of the market than you have. But if you call a major move correctly you can get ENORMOUS leverage without being caught in a squeeze if your bet goes wrong.

So if the copyright holders are aware of the copying there's no foul unless they think there's a foul and claim it.

They'd probably have paid for them and gifted them themselves if it wasn't more legal trouble and protocol clumsiness than the current situation.

    If they're concerned about the precedent they could explicitly announce they've authorized this particular set of copies, putting the issue to rest without waiving any other rights. But I'm sure they're more than happy to watch us all waste effort wringing hands about it. B-(
