I had a nice lengthy reply to your message on Saturday...with lots of links and good stuff, but the Moderators intercepted it. I could try PM'ing or emailing you the info, but I'm not going to write another one-page paper, only to have it vaporize into thin air again. Its a problem with posting more than I believe 3-5 links. I usually just not link the link but copy paste it. If it gets spam blocked, email amy

Here's some different angles

I wonder how many dead birds on the ground under it from flying into it. I guess its not a green treehouse []

It does. MIT isn't the first at everything. There's some wicked technology out there that's been around for the last 200 years or so. Stuff that'd make the everyday engineer giggle like a school girl and soil their pants. Very cool stuff indeed...but you'll never hear about it on the news, or even at the university level most of the time. Hint: 1st Law of Thermodymics depends solely upon what constitutes the ascribed boundary of a system. There's no law out there that says what exactly what that boundary has to be. Mother nature really doesn't care where we draw the lines in the dirt, we're still playing by her rules, in her sandbox. First why the chip on your shoulder. And second man up and show proof now. Don't leave us hanging.

Did you even read the article, it is the LED not anything else.

I have no idea what you are talking about

http://www.wired.co.uk/news/archive/2012-03/09/230-percent-efficient-leds MIT physicists have managed to build a light-emitting diode that has an electrical efficiency of more than 100 percent. You may ask, "Wouldn't that mean it breaks the first law of thermodynamics?" The answer, happily, is no. The LED produces 69 picowatts of light using 30 picowatts of power, giving it an efficiency of 230 percent. That means it operates above "unity efficiency" -- putting it into a category normally occupied by perpetual motion machines. However, while MIT's diode puts out more than twice as much energy in photons as it's fed in electrons, it doesn't violate the conservation of energy because it appears to draw in heat energy from its surroundings instead. When it gets more than 100 percent electrically-efficient, it begins to cool down, stealing energy from its environment to convert into more photons. In slightly more detail, the researchers chose an LED with a small band gap, and applied smaller and smaller voltages. Every time the voltage was halved, the electrical power was reduced by a factor of four, but the light power emitted only dropped by a factor of two. The extra energy came instead from lattice vibrations. The scientists involved have detailed their discovery in a paper published in Physical Review Letters, saying: "Experiments directly confirm for the first time that this behaviour continues beyond the conventional limit of unity electrical-to-optical power conversion efficiency." 69 picowatts of light, of course, is a very small amount -- so you're not likely to be able to read in bed with one of these LEDs. However, it could have applications in low-power electronics, acting as a thermodynamic heat engine but with fast electrical control.

http://www.freakonomics.com/2011/12/01/the-marginal-cost-of-the-mcrib/ McDonald’s has reintroduced its McRib sandwich. Consisting of meat that at one point belonged to a pig, it is now on yet another farewell tour, its sixth since 2004. (Actually, the first three were called “Farewell Tour,” the last three have been called “Reintroduction.”) The website the Awl.com points out that the reintroductions of this unusual product have all coincided with downturns in the price of pork. Seems reasonable to me: Mickey D’s assumes there is some best price for the McRib and compares it to the marginal cost, exactly as in our introductory textbooks. When the marginal cost drops sufficiently (and presumably the price of pork is the most variable item in costs), back comes the McRib. (HT to CVB)

I have spent somewhere around 200-300 dollars worth of items ranging from speaker wires, to rca to XLR, to hdmi, to cat 6 (the price between cat 6 and cat5e was negliable), to cellphone chargers, to rca connectors, optical cables, binding posts, laptop coolers, etc. Never ever had one problem.

I think the RF-83 were too big for the consumer market. Also I usually leave the rf-83in large and do not cutoff the frequency.

I heard 4 million or so. Last time Hurricane Irene came by it took a week for some people to get power. I was lucky to get power because the subtransmission line that got fried is only 1000 feet away. It supplied the other town as well so they had to restore that first. I swear when we saw the thing spark up it switched red white blue for 3-4 minutes. The other time it just sparked the whole town up brighter than lightning. We had what should have been 24-36 inches of the white stuff but the problem was it was slushy and wet/compacted. So we had about 12 inches of compacted wet snow which bent trees, Our neighbor's 70 foot oak tree is now half gone because it still had 3/4 of the leaves (It didn't even change colors yet) A brand new mercedes roof was smashed when the limb fell.

Everyone alright? My power was restored 4 hours ago (about 24 hours) after seeing what a tree limb touches a 69000 volt high voltage wire. Oh Happy 4th of July came early or late this year!
