    Wind turbine generation is such shit. If you have a lot of constant, unending wind, it seems like a good idea; typically, solar outclasses it by far.

    My analysis of solar has changed in the past month. I last looked half a decade or so ago, when the ROI for solar was 19 years; it's now 2.5 years. Seriously. What the fuck? The arrays are more efficient, and they're down from like $3.84/W for shit-efficiency panels that degrade rapidly to $1.81/W for high-efficiency panels that degrade by less than 0.7% per year and are guaranteed to have above 80.7% efficiency 25 years into their lifespan--with god damn microinverters and advanced monitoring systems. When did this shit happen? I can generate 9,800kWh/year with optimal placement, 9,200kWh/year with simple placement, and thus about $1500 of electricity and $1700 of SRECs.

They tried building a new warehouse in Seattle, but they couldn't because they ran out of cranes--as in, there are no more cranes in the United States with which Amazon could build a warehouse. They have to wait before they can build new warehouses to satisfy all of this demand for 2-day shipping.

  3. Citizen's Dividend first on Calls For Funding NASA Commercial Crew Grow · · Score: 0

    These NASA programs are expensive, bloated drains on the economy. They attempt to accelerate technological development by brute force, slowing down wealth creation and making the nation as a whole poorer.

    I've suggested a Citizen's Dividend which, as a secondary effect, causes the wealth cycle to speed up: the expansion of niche markets and the creation of new markets occurs more rapidly, speeding up the creation of new jobs. It also has secondary effects such as freeing up the application of wealth to more quickly reduce labor employment in a particular production line, which sits at odds with its effect of reducing labor costs and thus delaying the implementation of new management tools and techniques (such as automation) until they become less expensive.

    The whole thing is complex, but it should have a tendency to actually speed up movement through the wealth cycle, particularly in the area of creating jobs to replace those lost each time we find a way to more efficiently provide a good or service.

    The growth of wealth in our nation reduces the proportional cost of things like NASA. As we become more efficient, the total buying power increases: the full income (not GDP) of every business and individual, in total, can buy more shit. Since NASA is funded by a portion of the total income, it becomes able to buy more and better components and crew for the same taxes: if NASA is 1% of our income, doubling our wealth doubles NASA's effective funding, even if inflation doesn't keep up (i.e. even if there are only 1.2 times as many dollars) (although inflation lagging behind tends to be bad for those with debt; conversely, it would encourage lower-interest loans, which ... could also be bad, particularly for persons seeking mortgages, although those actually selling those houses are quite happy with a low-interest market).

    It's not precisely a prerequisite; but deploying a Citizen's Dividend first would provide greater opportunities to run a program like NASA in the long run, that long run being a very short projection--less than ten years. The budgetary requirements of NASA would shrink, which would make the required budget easier to justify.

    The real problem isn't the public nature of your data; it's the private nature of aggregate data.

    Because you carry out your activities in public, any individual who legitimately wants information about you can, without violating any laws, personally keep track of your public activities. Without publication or any direct action, the person is not harassing you or whatnot. The things you do are completely public and not subject to privacy protections.

    That, of course, implies someone is interested in you, personally, in the first place.

    With aggregate data, we can put together lists of all people whose public functions follow a certain pattern. This, then, draws our attention to those people.

    Most people don't realize the very criminal nature of human existence. A lot of folks have... mischief in their histories. Hanging in parks at night, casual adultery, illegal gambling between friends... hell, there's estimates that some 40%-70% of 20-year-olds have hooked up with underaged teens. These are all things that can put you in jail, and may or may not distress people in your community--some more than others, some not at all (nobody cares about your poker games in your basement with your drinking buddies). As it stands, these activities aren't actually harmful to society, or distressing at large.

    That's why we have strict, constitutional controls for searches and seizure: if your criminal activities aren't drawing any attention, your criminal activities aren't harmful to society. The police rifling through your belongings and arresting you on bureaucratic technicalities *would* harm society at large, creating a constant state of paranoia and resentment among the population, along with costly economic and social disruption.

    Aggregate public data collection and profiling similarly draws attention to people's behaviors, focusing legal scrutiny where it does not necessarily do the most good. As this scrutiny broadens, it necessarily dilutes the attention of legal enforcement from the important criminal activities which actually harm society. Persons whose activities are of no consequence are more frequently investigated and arrested, while persons whose quiet activities invoke a greater injury to their peers enjoy reduced law enforcement attention and a consequential lower risk for expanding their operations even further. Such aggregation could, as consequence, allow petty criminals to build and operate more substantial criminal networks with even less likelihood of police detection.

    Many forget the police are not law enforcement officers, but peace officers. Their job is to keep the peace; they are not lawyers and not expected to know the law. This is because police detect crime by detecting its effects: injury, death, property loss, and, above all, distress among the population. This fits well with the explicit prohibition on police actively looking for crimes without first having a crime brought to their attention by the public nature of its activities.

    Broad data collection and aggregation changes the public nature of people's activities. It distorts this function, leading to false positives and arrests of harmless members of society.

    But in the apprenticeship system, at least in union-strong states, companies don't hire trade labor directly; they go through the union and pay union rates.

    Which would be bad because it pushes up labor costs, slowing economic growth. All growth of wealth--that's the wealth of nations, the wealth of the poor, the middle, and the rich--stems from reduction of labor costs. In the long run, this is the reduction of labor *time* invested; changing the price of labor has important effects in a narrow reach.

    Reducing labor costs allows market effects (some fast, some decades-slow) to draw product prices downward. This places residual wealth in the pockets of consumers (typically, those who were not recently unemployed by reducing the amount of labor invested as a method to reduce labor costs), allowing more consumers to buy niche goods, or to buy new goods we just made up. This allows markets to expand to sell new goods and services, which requires invested labor, creating jobs. Cutting labor costs by reducing wages makes the overall turn-over faster; raising wages makes it slower; and we ultimately rely on cutting number of laborers. As such, we want lower labor costs which are high enough to support the labor market, since that will get displaced laborers re-hired quickly, and you do *NOT* want unemployed laborers piling up.

    Raising labor costs encourages the displacement of laborers and discourages the creation of new jobs. Imagine the sandwich making machine costs $14/hr, the burger flipping machine costs $10/hr, and the fry-making machine costs $7/hr. If minimum wage is $15/hr (ignore the complexities of payroll taxes on wages), we replace all these laborers at once; if it's $8.25, the fry-runners go first, and the burger machine and sandwich machine have to come down in price before we start firing more people. That lets us take a 10% unemployment hit and have some time to find those people new jobs, rather than taking 50% unemployment all at once and having expensive laborers nobody wants to hire without good reason.

    Businesses would benefit overall by increasing OJT, but they don't presently.

    You can make the argument; and you'd have to consider how that compares to the benefit of exercising a high degree of power over their workers, cutting salaries and benefits, and reducing the individual business value of any specific employee.

    I argue that training employees is much less risky for a business, and invests value in that employee. Retaining that employee is important. Because that employee has value to the employer, the employee has power; the employer faces expenses when trying to replace the employee, losing his value and needing to put that same value as outlay into creating a new employee (unless they stumble across an unemployed, well-trained professional wandering about). Businesses, thus, will prefer a market of labor saturation; and, in such a market, will save the outlay of expense in training non-skilled professionals to be skilled professionals.

    That says nothing about taking bulk, off-the-shelf skilled labor and adding new skills by OJT. There is, at present, simply no way to avoid that if you want to maximize the value derived from a skilled laborer. You don't need to take a high school kid who's into computers and turn him into a skilled programmer, though; you tell that kid to come back when he's spent 4 years not making any sort of income and going through rigorous job training at a local college or technical trade school, if you still have a job for him then, and if there isn't a better candidate in the other 500 people filing their CV for a single position at that time.

    That said, unless things change dramatically, I think support for college -- for those who would benefit from it -- needs to be maintained.

    This is true in the general sense; however, to say H1-Bs push people to McDonalds is ... fraudulent. I tried, really, but it's not a deception or a manipulation of facts; it's a blunt lie.

    We have unemployment. We have burger flipper jobs. Creating more unemployment won't create more demand for burger flippers. You're not expanding the number of burger flipper jobs.

    Basic labor expands linearly. That means making more wooden tables requires investing the same machines, fuel, materials, and laborers proportional to the production of existing tables. This is an overstatement, of course: machines, fuel, and materials are ultimately produced by labor at the most fundamental level; an industry which produces 100,000,000 tables and wishes to produce 200,000,000 tables must employ twice as much labor, or find a new way to make tables. That goes for supplying fast food, retail, and so forth.

    There are non-linear tasks. One is information: tracking 10,000 documents is not 1/1000 of the effort of tracking 10,000,000 documents; expanding payroll, legal contracts, and invoicing by 1000 times will require more than 1000 times the effort to get right. At a point, it can't be done in less time: employ 10,000 times as many employees and you still have millions of times the communications needs to line everything up--a nigh-on-impossible task.

    This is a specific case of the more general scarcity problem: if you can pull 100 cubic foot blocks out of the ground, you'll find the ability to scale mineral production is limited by access to mines. You can scale linearly as long as you have mines that all produce 100% anthracite blocks; but when demand increases such that you must supply 10,000,000 tons more coal per year than your mines provide, you open another mine which surrenders blocks of 50% anthracite and 50% rocks and dirt--for the same effort, making anthracite coal twice as expensive, since getting the same 100 cubic feet of anthracite requires twice as much effort. Since we can't work the existing mines any faster, you're going to have to pay us twice as much if you want that much coal that quickly.

    The difference between linear and non-linear tasks becomes plain when you account for the Industrial Revolution (Mechanization) versus the Information Age (Computerization).

    In Mechanization, linear-scaling labor jobs met demand by blunt labor, scaling because demand did not exceed linear supply and because the labor of spinning, dying, weaving, cutting, and sewing is the same for garment #1 as for garment #1,000,000,000,000 (farming the cotton will eventually run out of good land, and scale non-linearly). Massive reduction in labor caused a sharp collapse of employment, with nothing waiting in the wings.

    Computerization cut off the bottleneck of information management. That opened up businesses to expand to meet demands well beyond what human information management could accomplish, tracking all the invoices and legal requirements and payroll concerns more easily. Costs to supply a broad array of services dropped; and demand for those services, already existing in the consumer base (everyone wanted a $5000 computer; nobody could afford it), drove consumers to buy all these new, cheap goods and services, creating an ever-expanding job market to absorb all the displaced clerks.

    Just as Automation will be more like Mechanization--it will cut back on burger flipper jobs, but not create an equal number of machinist jobs--the replacement of higher-level jobs with H1-B visa jobs won't suddenly create a great and endless demand for burger flippers and cashiers.

    That, and the immense boost of worker value and thus power, is the natural consequence of eliminating all government support for college education, leaving the individual to find a job. Without this, most individuals won't afford workforce development education--college--and so employers will experience severe pain and profit losses due to a dearth of skilled labor. They would, thus, gain a competitive advantage by hiring entrants (high school graduates) for cheap, paying for their training and education, transferring low-skill and time-consuming work from high-skill and expensive laborers to the new guy (low-skill work, by its nature, either can't cause any damage if mishandled or can be reviewed quickly by a high-skilled laborer before going into production), thus cutting costs while the laborer developed. The new high-skilled laborer would be hard to replace, and thus valuable.

    The obvious implication is any business should, as a matter of eliminating worker power and driving down salaries and benefits, demand public support for college, either by free college or by loan programs. Loan programs put the employee under more desperate pressure, but also help drive up required salaries; free college relieves the employee from the constant beating stick of crushing, growing interest costs on deferred loans, but leaves you with a labor oversupply that still lets you toss out any employee who gets snippy, and reduces the pressure that makes them demand higher salaries even against their own desperate need for an employment of any sort.

    My understanding of economics actually makes this obvious.

    The submitter says this is aggregate, not specific individual. That's the crux of the issue: if you evict a small enough percentage of laborers out of a job at once, and you keep production even, you only cut costs and thus eventually reduce prices as consequence (complex market dynamics drive prices down; some are fast, some are very slow). As prices come down, the remaining consumer base ends up with more residual wealth (money), which allows them to buy more stuff. This expands niche goods or creates demand for new goods, which require labor to manufacture. That labor demand brings in new jobs.

    In total, due to Ricardo's explanation of comparative advantage, this effect eventually spreads all over: if we constantly outsource, the consumer base elsewhere expands, and the market for products and services increases e.g. in China; it being cheaper to manufacture certain goods or provide certain services in the American economic climate, China will outsource such things to America. In this way, each side expends less of its resource base to produce the same amount of shit, and thus becomes more wealthy.

    The turn-over isn't instant, which is why shit like the Industrial Revolution and the upcoming automation crisis kill economies: you unemploy 50% of your population in under a year and you see what happens. Time is a big factor.

    In hierarchy: We need a good number (4%-10%) of routinely-displaced workers (generally, underemployed poor people who frequently have too few working hours or spend swaths of time unemployed) to act as our moving workforce; we need a large number (80%+) of lower- to middle-class workers to act as our consumer base, creating demand; and we need a few (2%-10%) upper- to wealthy-class individuals who have high capital to divert to profitable business filling new demands and creating jobs to re-employ displaced workers.

    You'll notice this hierarchy demands a stable consumer force, and also recognizes the wealthy who step in to create efficient production means to reclaim residual wealth in the consumer force's pockets as job creators. Coasting businesses need most to reduce employment; they are not so much job creators, although their natural expansion as their products become cheaper does reclaim or repurpose some of the labor they displace off production in the process. In saturated demand markets, these businesses don't expand; they only make their products cheaper, employing less labor to do so.

I had 14 gauge wire hooked up to a major appliance on a 30 amp breaker (14ga is rated for 15A, 12ga for 30A--fire hazard), and all kinds of crap was just wired up wrong (electrical sockets and other major appliances wired to the dryer 220 breaker pair!). Hazards everywhere. I've seriously considered pulling the mains out, inserting it into a main electrical disconnect, and rewiring the panel from scratch. I'm no electrician, but this isn't much more complex than wiring a light socket up (a hell of a lot more safety issues, though, hence why you want a main power disconnect before you fuck around with it).

    We recommend an installation that covers less than 100% of your electrical usage because, in most areas, there is little financial benefit to producing more power than you can consume.

    Distribution fees, taxes, etc. I pay 11 cents per kWh; my total bill is 18.2 cents per kWh. For many people, electricity is 5 cents per kWh, and distribution is 3-8 cents. My power is 100% solar-wind; if it were cheap baseline power, I'd pay 8.9 cents per kWh, meaning over 40% of my electricity cost is distribution, taxes, and fees.

    I'm replacing my gas furnace with an $800 air handler if I need air circulation. I'm installing a $4000 split system for actual heating--100% load capacity down to 15F, 80% down to -5F. That's cheaper to run, and runs on electricity; that will ensure I never cut below my electricity consumption, meaning I'll never send power back to the grid, so I'll never have to worry about if they're going to pay me distribution fees and taxes (they won't) for my surrendered electricity. ROI stays at 100% instead of dropping to 60%.

    I'm still sealing drafts and installing insulation.
