Comment Because they didn't use the iPhone (Score 2, Interesting) 156

A big part of AT&T's problem is really that the iPhone's radio sucks. When tests are done using a different device, AT&T scores pretty good. I switched from AT&T (not the iPhone) to Verizon, and I don't see any improvement in call quality.

Comment Re:Bah! (Score 1) 720

No one has yet figured out how to extract "shale oil" - which isn't oil at all - without requiring more energy as input than the energy output you get in the crude oil.

Canadian tar sands are a bit easier to extract than shale oil. But for every unit of energy input, they only get about 1.5 units out in the form of crude oil. Fortunately they have lots of natural gas in that area, so that's what they use for energy input.

But they could simply use the natural gas to generate electricity, then use the electricity for electric cars and get a similar energy gain due to the fact that natural gas power plant and electric car have a combined efficiency better than the combined efficiency of an oil refinery and gasoline powered car.

"Republicans deny that this was a political choice" the WSJ reported

That's a story from an alternate universe, where publications like the WSJ really are fair and balanced. I checked out KPCB's webpage and found that both Al Gore and Colin Powell are directors. So why did the WSJ play up Gore's involvement, but not Powell's?

Here's an article that gives another possible reason. It's hard to recruit volunteers for a study that really have a condition like clinical depression. If you actually recruit a bunch of people who are just temporarily feeling down instead of having true clinical depression, then of course they tend to get better whether they were given a sugar pill or a real anti-depressant. And they would have gotten better if they had taken nothing.

Comment Re:What matters is the additional cost *you* incur (Score 2, Insightful) 345

But at some point, the addition of enough cars means you have to widen the highway, or build a totally new highway. Don't know about where you live, they're constantly building new roads here, and there's a cost for that.

There's also a cost to maintain the roads. And cars driving over those roads do damage that has to be repaired. Large trucks cause much more damage.

In both cases, it's hard to see that adding just one more car means a new road has to be built, or and section of road has to be repaired, But it eventually adds up.
