$this->bbcode_second_pass_quote('Dezakin', 'T')he reason I can't take it seriously is just looking at the numbers its just silly. Breeder reactors have been running, some for years or decades at a time.
Dezakin, we've had this conversation before. Yes, breeder reactors are real. However, when you put it that way, you make it sound like an off-the-shelf solution we can just reach for and use at any time. For example, if Saudi facilities were to be knocked out tomorrow, that wouldn't pose a threat to the U.S. because they could just switch to breeder reactors and make petroleum out of limestone.
Now, I know that's not what you want to say, because I asked you. The question at hand is how we are going to deal with a hard, short/medium-term crunch on liquid fuel, which has real implications on military power etc. Breeder reactors will play no role in the solution of that problem. So why bring them up? You're talking about a piece that isn't even on the board.
$this->bbcode_second_pass_quote('', 'S')olar concentrators work, they are just less competitive with other alternatives. The only way that the alternatives dont work is if you put out the sun. Even though solar power would be much more expensive in the short term, it certainly doesnt kill economic growth, and we can get petawatts of solar energy just from the earths surface.
Well then, clearly sprawl and waste pose no risk to the U.S. When natural gas poops out, U.S., industry can just switch to solar concentrators for process heat. And suburbia can be fueled with liquid fuel generated from rocks and solar concentrators. We might as well all drive tanks that get 10 gallons to the mile. Right? After all, there are petawatts of energy out there, so we're under no real supply constraint.
I know you'll complain that I'm creating a straw man, but you need to figure real-world limits into your numbers. We can't turn the entire crust of the earth into uranium tailings. We can't cover the entire surface of the earth with solar collectors. If you refuse to address the practical limits, then the straw man is an accurate characterization of your view.
As long-time readers know, I strongly agree with you about the power of technology and the freakishness of the future. But I think stupid_monkeys said a very wise thing the other day: "Technology can do the job, but we have to meet it half way."
