Apples and oranges. Silicon is cheap, so there's no incentive to switch. If rare earth elements become a problem, and solar is well developed at that point, other technologies will come in to take their place. Rare earth elements are not theoretically necessary to generate adequate power. If Germany can generate this much power from solar, it's pants-on-head stupid for people in Arizona to say that nuclear is better.

Oxford has already managed to get zinc working in place of indium, and there's a lot of research on technologies that don't use rare earth. Progress on solar is coming at a much greater rate than in fission.

It makes more sense to bet on breakthroughs in solar than in nuclear. Any startup can get into solar energy relatively easily. Nuclear on the other hand has a high barrier to entry. And you always have the Fukushima factor - do you really want a 20TWh reactor in the middle of Africa?

Climate change has a simple solution - reduce the number of people on the planet by 50%. This is something that we can do in two generations if we wanted. The "lot of people" you mention are very careful to avoid any mention of population control, which is why I tend to not take them very seriously.

Yes, but those "great leaps" have always been on the horizon - since I was in in high school and Reagan was president, and much earlier. If we get cold fusion, everything will change. If we get the next generation of batteries, everything will change. If we get motors that use 80% less energy, everything will change. If we can use nanotechnology to build better fuel cells, everything will change.

We can't count on the future.

We need to work with what we have right now, and yes, it will be painful. Germany is dipping a foot into that very uncomfortable swimming pool, and yes, it will mean higher prices, worse service, and so on. But it is unlikely that technology will allow us to indefinitely continue the lifestyle we have right now. Consider that at this instant, I can walk away from this computer, go to the gas station, buy a few 10 gallon jugs, fill them with gasoline, and drive across the country without depending on any refueling stops. It will be a long time before there is ANY green technology that can give me that level of speed and independence.

We have more than enough people telling us how difficult things are and how we shouldn't try - yours is just another voice in that cacophony.

What we need are people who tell us how to make it work. Nuclear plants might be necessary for a very long time, but they should be secondary to renewable sources.

The idea is to separate the five, so that it would be impractical for all five to know each other or to break your trust. So for example, your dentist that you've gone to for 20 years, your lawyer, a trusted coworker, your wife, and your brother in China.

Of course, the 3 and 5 are not magic numbers. You could make it 12 out of 13 if you're really paranoid. You could make it 5 out of 25 if you want very low possibility of your data being lost (for example a large earthquake).

Have you worked with service providers? From the time you've dialed their number, what is your estimate of how long it takes to get someone on the line who can lock down an entire corporate account? Remember that there's a big authentication issue there - how do they know it's not a prank call?

By comparison, I can get to our server center and completely isolate us and all our data from the Internet in under 10 minutes.

I think you're severely underestimating the numbers who can set up Roku or DVR on their own. Last year was the worst stretch for pay-TV ever. Apparently, a lot of people are figuring it out, because 8% of US households got rid of cable last year, and the trend has not peaked yet.

But there's a larger issue, because we're talking about two paths in the US. One is more mindless consumption, more cheap Chinese electronics that have to be replaced every two years, more useless channels, more keeping up with the Jones. The other is being mindful about consumption, simplifying life, and reevaluating what's really necessary. Everyone assumes the first path is inevitable, hence all the power saving talk.

Stop being a pedantic asshole.

Of course most people use electricity. My point is that you can reduce the amount of gadgets in your house, which is a better idea than accumulating even more materialistic crap and trying to save the planet my making it "green". Amazingly, a large percentage of the world's population survives just fine without a rotating antenna on their roof.

Uhh... if you don't have cable boxes, they don't use power? Sorry I didn't explain the logic at a 5th grade level. My antenna sits in the window and connects to the DVR, which is unplugged except for the rare occasion there's something on broadcast TV I want to record. The whole mess is on a power strip that I turn off when I'm not watching TV. I use a $35 Killawatt to see how much each device uses, so there are no surprises.

Yes, I have a device to turn my antenna for better reception. It's called "my hand".

Americans are always looking for the technological fix. Does anyone really need TV's in every room including the guest bathroom? Just reduce your consumption and try living a little simpler.
