If upping the voltage over what is currently done would be more cost effective, why isn't it done yet? I was always under the assumption that the big power lines were millions of volts already.
A honey pot is used to catch flies, so that you can do something with them. (E.g. throw them away, keep them from your food, dissect them. You know, whatever.) What is going to happen with these congressional staffers? "You've lost your wikipedia privileges" doesn't really sound like it stings too much.
It's not just about profit, though that in itself is a complex thing. Aibo may not be profitable by itself, but it can very well improve the profits on other products. And, of course, if you are using it as R&D that may not profit you directly, but can certainly allow you to create products that are profitable.
While I know you said "generally", I'd like to point out that I undervolted my desktop and did not underclock it. It's just the same as overclocking without overvolting.
I don't remember seeing anyone state that they've run out of battery power on a 2nd gen prius on an uphill climb. Certainly not on most any climbs out there. 1st gen, I have, though.
Are you aware of the fuel and emmissions costs of simply turning on a gasoline engine? They can exceed those of an engine idling for a minute or two.
Not with the Prius. Because when it turns on its engine it actually uses the motor to spin the engine up to its operating rpm before injecting the gasoline and sparking the plugs. When a typical car starts its engine with a starter as I remember it's only up to something like 200-300 rpm.
And you keep talking about these smoke and mirrors about total system pollution, but I don't see any numbers to suggest that the Prius is any more polluting over it's lifecycle than anything else.
Whoops, forgot this:
AT PZEV: Advanced Technology PZEVs
AT PZEVs meet the PZEV requirements and have additional "ZEV-like" characteristics. A dedicated compressed natural gas vehicle, or a hybrid vehicle with engine emissions that meet the PZEV standards would be an AT PZEV.
Prius: more leg room front/back
more shoulder room front/back
slightly more horespower, significantly more torque
more storage space
Aveo:
slightly more headroom in front, 1/2 inch more in back
500 pounds less
miles per gallon:
Prius: 60/51, maybe 44 real world for a typical driver Aveo: 26/35. Real world, I dunno. Split the difference and make it 30.
Emissions:
Prius: AT-PZEV Aveo: ULEV-II
ULEV: Ultra Low Emission Vehicles ULEVs are 50% cleaner than the average new 2003 model year car.
SULEV: Super Ultra Low Emission Vehicle SULEVs are 90% cleaner than the average new 2003 model year car.
PZEV: Partial Zero Emission Vehicle PZEVs meet SULEV tailpipe emission standards, have zero evaporative emissions and a 15 year / 150,000 mile warranty. No evaporative emissions means that they have fewer emissions while being driven than a typical gasoline car has while just sitting.
Maybe I chose a bad car to compare against, but I saw one this morning on the way to work, so I picked it.
The Prius' batteries can be recycled, so that's not a big problem, aside from the creation/recycling. Is that so bad? The motors? They're just a bunch of metal with a bunch of wires, no? EVerything else is pretty normal for a car. What about hybrids is so bad, in your estimation?
And I have ridden my bike to work quite a few times, thank you.
But the benefits of the Prius aren't limited to increased fuel economy. The systems in place reduce emissions by quite a bit. A "conventional diesel" won't reduce emissions any lower than that of a conventional diesel. Some say that reducing emissions is the primary goal of the Prius hybrid, and increased fuel economy is secondary. (Not that it is marketed this way, though.) Consider things such as the Prius running the engine not because it is needed for propulsion, but just to warm up the catalytic converter.
And what happens when a 1950's Mustang stops on the road? No black bocx signals, no warning. Or a storm happens and a tree gets knocked down in the road. Or a kid jumps out to grab his ball. Potholes? Black ice? Deer? Stoplights go out?
Let's face it. Automatic driving is a lot more complicated than it seems. You need the cooperation of *all* of the cars on the road, plus the roads themselves (to sense road conditions/hazards), plus probably sensors on the sides of the roads (for things like kids/deer). That's a lot of money and a lot of infrastructure. I would love to say "drive to the airport" and have the car take me there, but it's going to be a long way off.
Boy, that article gives way too much credit to the Slashdot crowd. "Bizarre and complex subculture"? "Highly developed and artistic attempts to provoke outraged responses"? Right...
Of course, you could sign all of your software, and run only signed software. Then trustme.synnantec.cn could not inject any code. Unless they h@x0rz Symantec and steal their key.
I think I found the reason: 1 GB of ram. That makes a big difference. I got my hands on a 700 mhz Intel laptop, installed windows xp and thought it was dog slow, installed Ubuntu and thought it was even worse. The machine had 64 MB of ram. So I traded it to my friend for a slower, 600 mhz machine, with a smaller hard drive, but 190 MB of ram, and installed Kubuntu, and it runs just fine. When running recent OSes the amount of ram makes a big difference.
What if Linux borrowed a.NET concept and created a Global Assembly Cache, where as many versions of a dll could be stored as you could want. When a program requests a dll it makes its request by version and the GAC delivers the correct version, or a new version based on a version redirection policy.

1. VW quality? Hmmm. 2. The Prius' batteries last longer than 3-5 years.

A gasoline car while just sitting emits nothing.
This is not true, and is something that the Prius specifically addresses, by having a bladder inside of the fuel tank.
And the quote about emissions levels and what they mean (and specifically about a car's emissions while sitting) were lifted from this site.
Whoops, forgot this: AT PZEV: Advanced Technology PZEVs AT PZEVs meet the PZEV requirements and have additional "ZEV-like" characteristics. A dedicated compressed natural gas vehicle, or a hybrid vehicle with engine emissions that meet the PZEV standards would be an AT PZEV.
And, by the way, what are "the emissions cost of the entire system" for the Prius? And for a similar car?
Compare the Prius to a Chevy Aveo:

more shoulder room front/back
slightly more horespower, significantly more torque
more storage space

slightly more headroom in front, 1/2 inch more in back
500 pounds less
