1. Solar CalculationYou know that global warming bugs me.

It also bugs me that real information is so hard to get.
Forget about $$$ and practicality and logistics for a second... if we had perfect solar panels with perfect batteries and all, how big a solar panel would we need for your average house?
It looks like the average household uses roughly 1,000 kWh/month; that's "one thousand kilo-watt hours per month". Give each month 30 days and we get about 30 kWh/day consumed. [

It looks like the power of the sun in Chicago is roughly 4 kWh/m2/day; that's "Four kilo-watt hours per meter squared per day. [
source]
Let's divide, shall we: 30 kWh consumed / 4kWh/m2 = 7.5 m2 or "Seven and a half meters squared". So, a perfect solar panel would have to be 7.5 meters squared to power the average house. But solar panels are only about 20% efficient (
source), so you'd need a panel 5x that size to do the job: 35 meters-squared.
That's pretty big. 6 meters x 6 meters.
But let's say efficiency doubles over the next 10 years, and let's say we only want/need to cover half our energy via these panels. That reduces our panel area by 4x to 9 meters-squared, or a 3x3 meter panel. Reasonable.
I'm tired and rambling... the point is solar is close to making sense. Closer than silly windmills. And of course, nuc-ular is better than solar. All this fossil fuel and global warming nonsense is addressed with a modicum on invention, which we are well on way.
Cap and trade and such... taxes and control, not about energy or warming or whatever.
2. InvestingGreat QOTD regarding the US and Asia from the Mad Hedge Fund guy... similar to a previous post, but still worthy:
QOTD"As much as we despise ourselves and wallow in our failures, Asians see us as a bright, shining example for the world. After all, it was our open trade policies and innovation that lifted them out of poverty and destitution. Walk the streets of China, as I have done for nearly four decades, and you feel this."

And how is your day today?
Well, Eddie Lampert, CEO and majority owner of Sears Holdings, is up about a cool billion $$$ today.
A Billion Dollar Day for EddieHe he.
3. New Year's Eve BookBook:
"Noah's Compass" by Ann Tyler

Review:
4 bill-stars (out of 5)... really good
Such a great treat for me... I found Ann Tyler's new book on New Year's Eve.
Smile.
Ann Tyler is one of my favorite authors, and "Noah's Compass" is pretty typical. Her stories focus on regular people going through pretty much regular stuff... no plot twists with Mitch Rapp or anything. He he.
This was a very enjoyable read: 4- bill-stars.
Ms. Tyler's writing style is so smooth... it just kind of ambled along. No biggie.
I thought Ann Tyler's "hook", Noah's compass, was kind of smarmy. Noah didn't need a compass "because the whole world was underwater"... get it? Meh.
Anyway, here's my favorite QOTD from the book:
QOTD"Epictetus says that everything has two handles, one by which it can be borne and one by which it cannot. If your brother sins against you, he says, don't take hold of it by the wrong he did you but by the fact that he's your brother. That's how it can be borne."
- Ann Tyler, "Noah's Compass"
Sort of a fancier way of saying, "keep your positivity."
Pick the positive, constructive handle of a thing.
I like it.
positivity... yow, bill
