I skimmed the articles too, the authors glossed over a lot, but where the heck are you getting your numbers? By way of example, a 3kW rooftop PV rooftop system TODAY would cost you around 3.50 / W for the modules (10.5k) and $2000 for the inverter, for only around 12500 in materials. (solarbuzz) You think there will be no more progress downward in PV module costs?

Funny you mention trig functions, I was just thinking this morning about the "black-boxishness" of trig functions.

I've wondered if maybe we'd be better of NOT teaching sin/cos immediately, and instead giving children Euler's identity first

Sadly, I've got to say, I never use Euler's, always the trig functions to solve real problems (I'm an electrical engineer.)

I've got a 3yrs old and a 2 years old and would love to see them have a better time with and a deeper understanding of math than I did.

Math was (and sometimes still is) a real pain for me, and I've never really understood why, becuase the rules are all very simple.

Not just pay folks who know how to exploit, no, they can pay folks who actually write the tax code! (congress) Look at the tax code, there's all sorts of crap like "15% deduction for drilling oil wells between 1003 and 1047 feet, in fartknock county, oblivia..." The tax code actually fills several rooms.

GE Closes Last US Light Bulb Factory 797

pickens writes "The Washington Post reports that last major GE factory making ordinary incandescent light bulbs in the US is closing this month, marking a small, sad exit for a product and company that can trace their roots to Thomas Alva Edison's innovations in the 1870s. What made the plant vulnerable is, in part, a 2007 energy conservation measure passed by Congress that set standards essentially banning ordinary incandescents by 2014 but rather than setting off a boom in the US manufacture of replacement lights, the leading replacement lights are compact fluorescents, or CFLs, which are made almost entirely overseas. GE developed a plan to see what it would take to retrofit a plant that makes traditional incandescents into one that makes CFLs but even with a $40 million investment the new plant's CFLs would have cost about 50 percent more than those from China. 'Everybody's jumping on the green bandwagon,' says Pat Doyle, 54, who has worked at the plant for 26 years. But 'we've been sold out. First sold out by the government. Then sold out by GE.'"
