  1. The downside to equality ... on Fate of Terry Childs Now In Jury's Hands · · Score: 1

    Pity he doesn't have a jury of his peers, so he's basically gonna get crucified by joe & jane blow citizen ...

    The downside to treating everybody as equal before the law is that everybody is everybody else's "peer" for the purposes of jury selection.

    "Jury of his peers" is from British law - where the Magna Carta established the right of Lords to be tried by a jury of other Lords in disputes brought by the King, to keep the King from arbitrarily convicting them of made-up crimes and seizing their estates. Later it was extended to the other classes of "Englishmen".

    When it comes to the US, while many of the legal principles came across, the explicit legal distinctions among classes of citizens, based on heritage, occupation, government position, etc. were explicitly banished from US law. We were left with free, slave/involuntary servant (a class later eliminated except for those convicted of crimes), non-citizen, and "untaxed Indian" (effectively citizen of an independent country called a tribe who hasn't opted for full US citizen status).

    About the closest we have to "peer" in jury selection is the requirement that the trial take place in the community where the crime occurred unless the DEFENDANT requests it be moved elsewhere and the judge agrees he can't get a fair trial in the original location.

  3. Consider the source. on Roger Ebert On Why Video Games Can Never Be Art · · Score: 5, Insightful

    Ebert is a movie critic. As such he has a vested interest in keeping people interested in spending their eyeball time on movies rather than "diverting" it to other passtimes, such as video games. This constitutes a conflict of interest whenever he attempts to analyze those passtimes.

    Again, Ebert is a movie critic. This means he thinks movies are something more worthy of his attention than other passtimes. This can be expected to produce a subjective bias whenever he attempts to analyze other passtimes.

    While this may be his actual honest and informed opinion, rather than a conscious attempt to promote his own subject matter (and thus his career as a critic) or an unconscious bias manifesting as a denigration of other art(or not)forms, I am inclined to take what he says about video-games-as-art with a large salt lick. (The same one I used in the '50s through now when blithely ignoring the mainstream literature establishment's constant criticism of both science fiction - which has an opposing ideology - and graphic novels / "comic books" - which bear the same relationship to written literature as theater does to storytelling.)

    I am reminded of the TV show episodes during the rise of various things perceived as competition to network TV - cable, internet-based conferencing (netnews, blogs, ...), and again video games - which attempted to tie video games to crime, drugs, death, etc. (For example I recall one particularly pathetic (and low budget) cop show (involving "The San Diego Chicken" as a major character and witness) where the murder was committed by an executive of one of two cable companies involved in a bidding war.)

    I hope Ebert is not sinking to this level.

  4. Wings come straight out of payload. on Shuttle Reentry Over the Continental US · · Score: 1

    I wonder if there couldn't be a more aerodynamic shape it could use to reduce the friction from the atmosphere.

    Every additional pound of wing is one less pound of payload. The shuttle comes in dead-stick and has no capability to come around for another pass. So enough wing to get it to the runway is all the wing it should have.

    As it is (if what I heard from someone in the industry back in the day is correct) the shuttle has FAR too much wing for the mission profiles on which it has been used.

    The shuttle was a combined civilian-military project from the start - intended as a cost-saving measure (and/or to suck in military money to make the project possible). So it was designed to handle both civilian and military missions. Civilian missions typically involve near-equatorial orbits (science platforms, synchronous-orbit comsat plus low-to-high-orbit booster, etc.) These launch to the east (mainly from Cape Canaveral) to get an initial boost from the Earth's rotation. Military missions have a higher proportion of polar orbits (such as observation satellites - where one can see the whole globe because the Earth turns under it.) Polar orbits get no help from the Earth's spin and thus have much less payload for a given amount of vehicle and fuel. Intent was to launch them to the south from Vandenberg.

    But the military had another mission in mind, back in the cold-war days, which got designed in. This was a fractional-orbit "pop-up" scouting (or something...) polar mission: Launch south (or potentially north, though this takes you over land in case of trouble), once-around getting your pix (or doing whatever), and land after one orbit. Ideally you'd land the same place you launched from (i.e. Vandenberg) so you can immediately recycle the craft, rather than having to mount it on a 747 to ferry it from the landing to the launch site. But the Earth turns under you while you're in orbit. A "normal" mission can just multi-orbit for one or more half-days until the launch site is under the track again. But on a war footing you can't wait a half-day: a) you might get shot down (losing the info and/or the scarce military resource) and b) your info is delayed. So a one-orbit pop-up mission means you need a lot of cross-track aerodynamic capacity: Come down to where you're out of braking and into gliding mode, then turn east and chase down the landing site. To handle this mission the shuttle was given those much bigger wings.

    There's a stock ratio for rule-of-thumb ratio for computing a low-earth-orbit vehicle's polar payload as a fraction of its near-equitorial payload. Story goes this was applied to the Shuttle in the early design phases and it came out with a decent number even with the big wings. But the problem is that it was applied to "payload" as in "payload bay capacity". In the case of the shuttle THE ORBITER IS ALSO PAYLOAD. With the bigger wings it can still do a polar flight - but after deducting the orbiter, crew, and consumables you end up with a payload of a couple hundred pounds. And this was figured out too late in the design phase to rehack it.

    So the military got their pop-up mission - but lost the ability to do polar satellite launches. After this was discovered they abandoned the construction of shuttles for the Vandenberg base, mostly bailed out of the shuttle program, and did their own regular-booster satellite launches. The Vandenberg shuttle-launch facility was mothballed (except as a backup landing site) and the Shuttle was always launched from Canaveral.

    Now maybe it wasn't really a mistake. Maybe they were intending to use one of the intended followon replacements for the boosters/tank combo that might have given them nontrivial polar capacity - and finances never materialized. But the net result is that the shuttle has too-big wings,thus way-expensive launches, thus didn't do all that many launches, thus never developed the economy-of-scale that would have brought the price down SOMEWHAT (though never to where it would have been with dinky wings.)

    Bummer!

    "Now, the making of solar panels already use up more energy than they're able to produce in their lifetimes... wny make the energy (& $) cost any greater."

    No, no they don't. Manufacturing energy payback is around two years on average, with variations for manufacturing technique.

    Not to mention that, even if it wasn't outright false, it's an apples-to-oranges comparison

    For starters, much of the energy cost of making panels is in the form of raw heat, not electricity. Nobody in his right MIND would burn solar electricity back to heat through a resistor for that purpose - throwing away a carnot-cycle ratio. If you INSISTED on using solar power to make panels you'd use things like solar furnaces, not photovoltaic panels, for your heat at a 4-to-1 or better boost.

    Bit the target it to provide energy in the form of electricity to a particular site. What are the alternatives: If it doesn't have a water resource for microhydro generation or a wind regime suitable for a practical mill, the alternatives are a local fuel-driven generator or the far more efficient utility grid.

    Fuel-driven gird consumes MUCH more in BTUs than it delivers in watts - because it's FAR from 100% efficient at turning heat from combustion into electricity at your wall outlet. Since it's a heat engine you start with the carnot cycle efficiency, deduct resistive losses, steam leaks, corona discharge. Then there's the energy cost of constructing the infrastructure: For local generators: Building the engine and generator. For the grid: building the power plants, making the iron, copper, and glass for the generators, transformers, wires, insulators, towers, meters, switch boxes, and circuit breakers, cutting and chemically treating trees to make poles, clearing a path, erecting poles, stringing wires, bringing workers to and from the sites, ...

    But energy isn't the only cost. Power generation and delivery affects a lot of environmental and other human values: There's pollution. There's depletion of resources. There's despoiling of other aspects of quality of life.

    Money costs generally map the sum of ALL those costs pretty well. When solar R.E. at your site (absent subsidies) is past financial breakeven with grid power, it's probably a better all-around deal for all the affected values as well, including energy cost.

    Given that oil companies are major producers of the current solar panels it seems silly to blame them.

    Oil companies realize that they are really ENERGY companies. They also know that most of the money they collect for oil products goes to the people and countries that supply them with feedstock and that oil isn't the only form of energy that can make a profit. And they know that oil will eventually run out and before that crude will get WAY expensive and people will switch to other stuff.

    So if you want oil products they'll sell you oil products and make a few percent. If you want solar electricity they'll sell you panels and make maybe more on their investment. And so on for a number of energy technologies.

    = = =

    IMHO the issue is that we have a burst of inventions that make incremental improvements but aren't many of them that has all the criteria for a switchover:
      - Big enough improvement to get people to switch.
      - Manufactureable at reasonable cost.
      - Makes sturdy, safe, reliable products.
      - Is enough ahead of the REST of the pack that it will grab enough market share to pay off the cost of going to market and not get bumped by another upstart.

    That said, there has been a continuous improvement in the price/performance ratio.

    A decade or so ago you'd have to pay $10/watt or more, making a solar-powered house financially practical only for new construction in rural areas where you'd have to pay more than the price of the PV setup to string the grid to the site.

    These days, if you are willing to accept "irregular" panels with slight cosmetic defects, you can get UL approved panels for under $2/watt, and unmarked panels (for sites where insurance and code compliance aren't an issue) for about $1/watt. That's cheap enough to beat grid power in many suburban areas if they have good solar input, even without governmental subsidies.

    Then add in construction subsidies and income from selling alternative-generation credits to power companies and you can do well in many other places.

    And there ARE a few still-more-improved photovoltaic technologies that ARE just coming into production. And others that look simple enough to quickly add to existing processes for a big gain (like the nanoparticle frequency-shifter coating.) So expect the prices to be driven down still further.

    When solar cells are connected in a series string, the current output of the string is limited by the current output of the cell (or paralleled set of cells) with the least current output.

    Typical solar panels are either a single series string wound serpentine style back-and-forth over the panel, or a set of several series strings connected in parallel with paralleling jumpers across them every few cells. In the first case shading out any single cell drops the output of the whole panel. In the second, localized shading knocking out one or a few cells will similarly produce a drastic drop in output.

    But if the array is built of many cells and intended to operate with various patterns of shading, they can be connected in parallel groups so that the total of the group is pretty much constant, then these groups connected in series to achieve the desired voltage. Alternatively, each small patch (which would pretty much be all illuminated or all dark) could be made up of a series string of cells, and these strings connected in parallel to form the array. In these cases the problem would either not arise or be greatly mitigated.

    Since the panel is being designed for patchy and varying illumination the interconnects can be co-designed to work properly.

At this point, being used in medical experiments was a way to complete that assignment and contribute to "humanity" in the process...

    (Another example: Consensus decision-making evolves into totalitarianism in the presence of the normal fraction of psychopaths. First diversity and dissent paralyze group action. Then social pressures for conformity are developed to break the deadlock. These grow to be nearly irresistible. Then an individual or small group withholds consent except when the rest of the population does what they want.
