The basic idea is simple: you put three lasers inside the TV (one red, one green and one blue) and then scan the beams across a rear-projection screen using mirrors. By scanning fast enough you eliminate flicker. The lasers are so bright that you get a great image.

The advantages include:

1) Brighter, better saturated picture, even at large sizes.
2) Wider color range and very precise colors
3) Better energy efficiency at large screen sizes - perhaps half the power of an LCD, even better compared to plasma.
4) Long life, since lasers don’t degrade.
5) Large screen sizes at relatively low cost.
6) 3-D capable because of high scan rates.
7) Thin screens compared to other rear-projection technologies

The video predicted that we would see laser TVs in about 18 months. And here they are, shown in a public demo yesterday:

I've often bashed on LCD because I believe that display screens should inherently create photons - call that approach "inherently emissive". LCDs on the other hand depend on a backlight to create white light, and then selectively absorb parts of it with filters to make the colors you see on the screen. I call this approach "inherently destructive." You are guaranteed that much of the power you put into the back light will never make it into the viewer's eye, because the screen inherently absorbs part of the light. This leads to less bright, less vivid images; limitations on viewing angle; and all sorts of other nasty crap. LCD's only advantage is that they're light, and less of a power-hog than CRTs (what isn't?). I was hoping that OLED technology would come along and kick the crap out of LCDs, but this laser stuff looks pretty good too.

I'm very skeptical of this "teh lay-sars will last forever!!1!" talk. Given the multi-thousand price point they're talking about, maybe that's true. But if these laser TVs go to mass market, they're going to find a way to reduce the manufacturing cost. And that way will almost certainly result in a reduction of the life of some crucial component. Also very curious how they scan the laser beams. Probably not with a spinning mirror in a tilt assembly - more likely three digital micro-mirror devices like the ones used in DLP TVs.

"This was the largest single act of class warfare in the modern history of this country," Rep. Dennis Kucinich, D-Ohio, who led the fight in the House against the bailout, told me by phone from Cleveland. "It is a direct attack on the American people’s ability to be able to stabilize their homes and their neighborhoods. This single vote will define the careers of everyone. We are back to taxation without representation, to markets that are openly rigged."

"We buried the New Deal," he said of the vote. "Instead of Democrats going back to classic New Deal economics where we prime the pump of the economy and start money circulating among the population through saving homes, creating jobs and building a new infrastructure, our leaders chose to accelerate the wealth of the nation upwards. They did so in a way that was destructive of free-market principles. They ripped away all the familiar moorings. We are in an uncharted sea where the traditional roles of the political parties are being switched. The Democrats have unfortunately become so enamored and beholden to Wall Street that we are not functioning to defend the economic interest of the broad base of the American people. It was up to the Republicans to protect not just a so-called free market but the American taxpayer and attempt to block this. This is an outrage. This was democracy’s Black Friday."

I know that Kucinich isn't the only, nor even the first, to say these things. Ron Paul has been saying them for much longer, for example. Still, I find this particular repetition to be particularly effective, mainly because of who's saying it. When both uber-lefty Dennis Kucinich and uber-righty Ron Paul are saying the bailout was horrible, it might force some people to think who probably wouldn't do so otherwise.

In case you haven't been watching the news...

Step 1) the Department of the Treasury admitted that they pulled the number $700 billion out of thin air.

Step 2) Congress proceeds to reject the $700 billion bailout. Later the same week, Congress passes a bailout for $810 billion. (Evidently the first bill didn't have enough pork for their liking. Also, we wouldn't want to strip those incompetent economy-destroying CEOs of their tens of millions of dollar golden parachutes, now would we?)

Step 2.5) The Dow bottoms out at 800 points below where it started the day.

Step 3) PROFIT!!!!!1!

The thing I want to ask you, America, is this: Why are you acting all surprised and indignant? DC has been fucking us over in just about every conceivable way for the last 8 years running. And it's only NOW that you're waking up and noticing?

Fuck the lot of you. I abandon you to your much-deserved fate. Enjoy your empire. You voted for it. Twice.

Parting shot: How many of you idiots believe that this is the bottom - that things can't possibly get any worse?
