If you can figure out how to mass produce carbon fiber parts, you can be a very rich person. It's easy to do in small volumes, and incredibly difficult in large volumes.
Regulations don't trump physics. Auto manufacturers all want fuel efficiency - if you come out with an SUV that gets 5mpg better than the competition, not only do you get more sales, but it helps you with CAFE. Unfortunately, it's not easy, even though you seem to think so. What vehicle components do you suggest be made lighter, and how? Can you tell me how to get a huge cube through the air at 80mph and not use a lot of power to do so? The bottom line is that the consumers have to make behavioural changes. It's not something auto manufacturers can push down.
The average insolation for the Earth is approximately 250 W/m^2 (http://en.wikipedia.org/wiki/Insolation). Assume a conservative 2 m^2 on your car, and that's 500W of insolation. Multiply that by a 20% conversion efficiency and you're looking at 125W. Over the 8 hours you're at work, you're looking at 1 kW-hr, or 3.6 MJ - about the energy in.03 gallons of gasoline @ 45MJ/kg heating value.
Even if you assume 3 times the efficiency of an electric motor/battery system that means that a solar roof will get you approximately 3 miles. Insignificant? No. But if you live that close to work, a bicycle will do the job even better.
You don't get charged for the messages from the carrier, and you most definitely can have text messaging disabled. I called AT&T and asked them to turn it off, and they obliged. I can neither send nor receive text messages now.
People have been trading freedom for security for decades now - whether it's in the form of expanded FISA powers, or in the form of restrictive gun control, Social Security, etc. People set up the slippery slope whenever they decided that the Constitution should be ignored for their benefit, and now we all pay the price.
Unless we're going to have superconducting transmission lines, proposals like this just don't make sense due to the transmission losses. Otherwise solar power in the desert would work too. Perhaps you could colocate things like aluminum plants, but otherwise, this is yet another "feel good" idea.
I completely agree - but do look into induction cooktops. I haven't used one, but people who have tell me it's as good as gas for heat generation, since the stove itself does not get hot.
The problem is that the environmentalist movement is not made up of technically savvy people. They do spread FUD all day without any interest in gaining a real understanding of the underlying technologies, their risks, and their rewards. Partly, that's because the masses have lost trust in science itself (look at the creation/evolution "debate"), and science no longer wins over public opinion. That's extremely frustrating to the engineers who understand the issues involved.
What's your source for this? Why would a jetliner do anything to a nuclear power plant? Do you realize what those containment vessels are like? And even a breach of the containment vessel doesn't render anything uninhabitable for 5000 years. Even Chernobyl didn't/doesn't have that problem.
No they haven't. They just didn't provide the static libc. If you install the static libc, you can compile static binaries. What does that have to do with ld?
It's not the 1B colors that matter, but the gamut. Do you agree there are colors that most monitors can't show but do exist in real life? Think of neon greens, bright magentas, etc. This monitor, covering the Adobe RGB gamut, displays colors other monitors simply can't. That may not matter to you, but it does to photographers.
I don't see what my parents' origin has to do with this topic. I think of myself as more American than the socialists who dominate Slashdot nowadays.
If you view web videos all day, you should pay for it. Why is that a hard concept?
Get with the program, my stoner friend.
And there's a whole other demographic that wants America to be just like Europe, not realizing that there are real geographical and cultural differences between the two. Trains in America make sense for select high density sections. Montreal to Boston has nothing between them. It simply doesn't have the density of the European countryside. What's the advantage over an airplane?
BTW, VIA rail isn't exactly a shining example of great public transit infrastructure either. I've ridden it.
A maglev train at 300mph isn't free to operate. It uses a lot of power, maintenance, etc. And I can guarantee that all the LA people won't choose to use the train instead. A good number of LAers shun public transit.
Are you kidding me? Could you imagine the infrastructure cost of a Chicago-LA maglev? Even at a relatively conservative $10M/mile, that's $20B. And at 300mph it would still take almost 7 hours.
Air is an effectively unlimited resource. Roads and bandwidth are not, and therefore should be priced based on usage.
Why should someone who uses only email pay the same as someone who transfers 200GB/mo of movies?
The law of supply and demand existed 5000 years ago as they did today. I don't understand why high school economics seems foreign to otherwise intelligent/educated people.
Now say your CEO's time is worth $1000/hr. If you waste 10 hours of his time because he can't use a PDA, you've already made up for the price difference.
You have to multiply the cost by the probability of occurrence. How often does someone really lose their phone? And then what is the probability that the person who finds it knows the industry well enough to sell it to someone who cares?
Exactly. The very fact that PDAs have mainly email available on it, and that email is inherently insecure (unless used with an encryption architecture, which it never really is), means that the PDA is not in and of itself a security risk. Loss of productivity has a cost too, and many Slashdotters forget that.

And thousands upon thousands is too insignificant to justify a full engineering cycle, when they're selling over 2 million macs per quarter.

Solar won't do much here.

Thinner by 0.01 inches - that's 7 years in the future for you!

When the government can safely afford to build, without going into debt, they should spend money on solar and wind power

Once the airport operations manager is bought off, the TSA deal is pointless. I'm sure he has a pass to drive his vehicle onto the tarmac directly.

That we are irresponsibly spending $500B that we don't have doesn't mean that spending $20B that we don't have is responsible.

People who are idly surfing are using a negligible amount of bandwidth and their costs will reflect that.

Nothing stops you from leasing (or even laying) a whole bunch of fiber and starting an ISP. Go for it, and you can charge less than everybody else.
Now say your CEO's time is worth $1000/hr. If you waste 10 hours of his time because he can't use a PDA, you've already made up for the price difference.
