Comment Re:Ground water pollution. (Score 1) 154

My Dad's water well had methane, not the "chemical analysis report" kind of methane but the water fizzed like soda pop kind of methane. There were no oil or gas well, nor were there any coal mines, just an oil seep down by the river. We pretty much avoided glass water glasses because pressure surges from the methane would knock the glass out of our hands.

Powerline Electricity has a wavelength of 6000 Km, which means that it's highly likely that even without loads connected to the grid, the constructive and destructive interferences of the different generators which is very likely to be analysable to produce a geographic area within a knowable error radius. Start adding in unique charecteristics like dead-spots in the generator's comutators, odd harmonics caused by the unique differences in how the stators are wound and even the number of stators used, and we're getting to the question of whether is works in reality or just in theory, and if it does, does it work better and easier than other methods.

GPS chips are pretty much everywhere and would provide an extremely accurate time reference, this could allow locations to be infered from power line conditions. Knowing this is at least plausable, counter-measures would be vary from trivial to very complicated, one could even record conditions at one location and inject them into a video recorded in a different country.

Some people are seriously sensitive to Fluorescent bulb flicker and others are sensitive to the low CRI of the fluorescent bulbs typically purchased by offices or landlords; which make having CFL's, halogens or incandescent bulbs an ADA in some workplaces. Electronic ballasts elliminate flicker and save energy, I've noticed that the rooms that I've replaced burned out magnetic ballasts with electronics seem to get used more and the rooms with CRI bulbs 85 or higher get used more as well. Additionally the electronic ballasts seem to be able to light the bulbs longer.

I have a hard time thinking of England as a good place for solar pannel installations, my mental image is a damp, cloudy, chilly place dominated by rain driven by the Gulf Stream influences; more like our Pacific Northwest temperate rain forrests in Oregon and Washington. I hate to think of people on fixed incomes dying of hypothermia because they couldn't afford to both heat their homes and pay for their solar pannels to fight global warming that hasn't happened for 18 years.

Germany doesn't sell daytime power "at a loss". Power at night on the European grid doesn't sell for high prices. Show some citations, ye of eyebrow raising claims.

Well let's see;

Over the weekend, prices on the power exchange in Germany/Austria (Phelix) fell to roughly -2 cents per kilowatt-hour for peak prices and were also slightly negative at around -0.3 cents for baseload power. The effect of solar and wind in France was even more dramatic, though the roles of baseload and peak power were reversed, with the former costing -4 cents and the latter -2 cents. Negative power prices on the weekend

Selling at a negative price is pretty much the ultimate definition of "at a loss". This is reinforced by

Lower prices “leave a trail of blood in our balance sheet,” Bernhard Guenther, chief financial officer at RWE, Germany’s biggest power producer, Germany’s New Coal Plants Push Power Glut to 4-Year High

While the baseload coal plants are losing money;

Norbert Allnoch, director of the Institute of the Renewable Energy Industry (IWR) in Muenster, said the 22 gigawatts of solar power per hour fed into the national grid on Saturday met nearly 50 percent of the nation's midday electricity needs.
Never before anywhere has a country produced as much photovoltaic electricity," Allnoch told Reuters. "Germany came close to the 20 gigawatt (GW) mark a few times in recent weeks. But this was the first time we made it over." Germany sets new solar power record, institute says

That's a lot of power to have to replace when the sun goes down or the weather turns to shit.

I didn't mean that as demeaning to people who are truely skilled at HTML and graphic arts and it is something that my brain just isn't innately wired for doing; but there are a lot of diploma mills that will cover PHP, Perl and Apache administration in half a semester and JavaScript and Flash in the other half. People with these "Web Programmer" certificates often mistake themselves for procedural language programers.

When versioning was a problem, most hosts had multiple versions of PHP so you could choose the one that worked, and if one didn't work it was mostly due to your code being sloppy and using techniques that were depreciated for years prior. Now it's usualy due to your code depending on an insecure settings in the php.ini file and again being depriciated for years.

What foundations do that? I agree that they are not non-profits if they are charging support or consulting fees. Usually they don't do that.

Excuse me but that is exactly what "Based on ability to pay means", if they can squeeze a "charging support or consulting fees" out of you they do a suprising amount of time. 501(c)(3)'s are some of the biggest rackets there are; but never count on the USG to not throw out the baby with the bath water.
