"I'm hearing a lot more interest from buyers who have called up and said they want the greenest house in Portland," Heslam said. "For a growing group of people, rather than having the fanciest house on their street, they'd rather impress their friends by having the greenest house on their street."
It seems more and more that people define their "greenness" as part of their social status. I mean, from hybrid cars to these energy efficient homes, it seems like people have transitioned to environment friendly ways not so much to be friendly to the environment, but rather for others to see.
I suppose part of it shows the philanthropic side of a person, taking care of the poor, defenseless environment that everyone abuses. Part of me wonders, if it were cheap enough for everyone to do, would the wealthy still do it, or would they simply indulge in the excess which they can easily afford?
Yeah, a few minutes of working it out gets it...in this case, you start by noticing that E and N have to be one of 5 or 0, and then you realize which is which. After that, you see the most significant digits on "forty" are all different from "sixty" which implies that there are carries on each, and there are upper limits on each carry (if you at any time say "carry the 7", you've made a mistake)...
Bottom line (in the order of discovery), N=0, E=5, O=9, I=1, T=8, then all together you get R=7, X=4, F=2, S=3, and Y=6)

Also, the right justification was easy, just use "Plain Old Text" and put in the spaces...
It would halve the ohmic losses...I don't think so, I think it might quarter them.
Assuming that we'll consume the same amount of power and knowing that 110V is the RMS voltage (i.e. DC-equvalent voltage), we can see that the current is going to be halved. However, the power losses due to that current are I^2*R. Thus (0.5*I)^2*R = 0.25*I^2*R, so we'll consume 1/4 the amount of power in ohmic transmission losses.
However, this overlooks the fact that much of the power distribution occurs over much higher voltage lines (we're talking kilovolts here, which is why those "big" power lines have such "big" insulators holding them away from the structure). It still doesn't make it a bad idea though...no matter how you cut it, a watt saved is a watt earned, wattever that means...

So close....Second Post!
