Comment Great idea, but nothing new (Score 1) 436

This was done in Hungary about 25 years ago, using networked traffic lights on "Soroksari Avenue". The lights are all synchronized to create "green waves" and there are digital sign posts indicating the optimal speed to sync up with the next green wave.
If the optimal speed was over the speed limit, the signs just display a dot.

Comment Finally! (Score 1) 244

I can't tell you how many old stock CPU coolers are sitting in my drawers (they make lousy paper-weights). The first thing I do when I build a system is get a quieter, more efficient CPU cooler.
The stock coolers are too noisy and inefficient and it's impossible to get an OEM CPU any more.

Comment Oh, there is room for improvement... (Score 1) 177

Game consoles are light years away from the point where we can say there's little room for improvement.
Maybe if hardware speed improved trillion-fold overnight, we could "rest" for a while.
I want to do real-time multi-spectral global-illumination rendering with volumetric effects, trillion-triangle scenes at a minimum of 1920 x 1080 60-progressive with 16x anti-aliasing.
Current games struggle to hit 1080 60-progressive, even with rasterizing GPUs, no anti-aliasing and are a far cry from anything you can do with ray-tracing.
Despite their massive artistic content, even the best-looking games still look way too "video game-y".

As much as I despise Microsoft (I use Linux and Mac exclusively and I won't touch anything Microsoft with a 10 foot pole),
I can relate to the workers.
For example, I really tried liking Firefox and used it for over a year, but eventually went back to Mozilla because I can't live without the *built-in* email client.
The Firefox-Thunderbird combo is just not the same.

Comment And they needed a study for that? (Score 5, Informative) 510

It's physics 101.
Capturing a larger cross-section of moving air is more efficient.

The reverse is also true (generating thrust):
Turbofan engines are more efficient at lower air-speeds than straight turbojets.
Moving a small amount of air at a higher velocity will create more wasteful eddies than moving a larger cross-section of air at a lower speeds.

Helicopters are the extreme case WRT aircraft.
You need a lot less power to make a helicopter hover than a ducted-fan or jet VTOL aircraft (like the Harrier or the JSF).

It reminds me of people who are surprised that electric cars / hybrids take up the most energy when they accelerate.
Duh, that's when you're actually gaining kinetic energy.
In cruise, you're just fighting drag (air) and friction (road).

Comment Two words: "early adopters" (Score 1) 769

Somebody has to buy the first few thousand Volts at a higher cost, but one production ramps up, I'm sure the price will drop.
This is nothing new.
There are thousands of examples...
The first Toyota Priuses (plural: Prii?) cost a lot more than they cost now.
In fact, I bought a 2008 Prius (even though I prefer buying used cars) because it was CHEAPER than the 2007 model, which was cheaper than the 2006 models!
