I've noticed that LED bulb packages say they'll last several years, but so many of them die after just a year or so. I should start tracking this precisely, but I've just gotten the sense that they often die prematurely.
I got that impression too, but it does say "But the path he has chosen involves one of the toughest problems in battery science, which is how to make an anode out of pure lithium or sodium metal."
I suppose that implies he's trying to make an anode out of pure lithium or sodium, but you never know with science journalism.
I opened the "Summary for Policymakers" listed right on their home page, and it popped up a PDF titled "AR5_SYR_FINAL_SPM-1.pdf". That's where I searched on the word "vapor" and found only one occurrence -- inside the word "evaporation".
I guess the "for the Physical Science Basis" report is something different that I haven't found yet.
Yes I understand that effect, and it makes sense that higher temperatures might cause more CO2 to come out of solution, as in a bottle of soda going flat more quickly at room temperature than in the refrigerator.
That said, I am not certain that the recent dramatic spike to 400 ppm of CO2 (from what I've read) could be entirely caused by the fairly moderate temperature rises measured in recent years.
Are there any data on water vapor concentrations? I ask that because I have read that the contribution of water vapor to the greenhouse effect is perhaps two to four times greater than CO2.
Sorry I deleted my comment out from under your feet. He was responding to my exclamation about the large spike upward in CO2 levels on that first graph on the EPA site. After posting it, I deleted it because I answered my own question.
There you can see a strong correlation between CO2 levels and temperature going back nearly half a million years. Teasing out cause and effect is the interesting task.
It's bizarre that it would be illegal. For all I know, it might be illegal in Peru too, but it happens, and it works pretty well.
In Lima, the spotters are known as "dateros" (loosely, "data wrangler"). The bus drivers pay them roughly 20 centavos, I think per stop but I'm not certain.
One case where it doesn't work is when certain bus drivers ignore the system and aggressively jump ahead of other buses. Nevertheless, it's pretty smooth.
Yes, you're talking about 4.7 cubic feet of gold there. Buy the island and then you'll have a place to store 1 cubic foot of gold, to pay your routine expenses.
Some have already closed that exit, banning the storage of cash in their boxes. They want to keep your funds available for negative interest rates and possible bail-ins.
Not only that, they took a lot of money in exchange for that "free" eduction -- often from people who didn't even use the service. So no, they don't have a "stake" in the products of anyone's mind. That's repugnant.
We traveled to Lima a few years ago, and the variety and quality of the food in the grocery stores and restaurants was astounding. For the equivalent of 2 to 5 bucks, you could get a lunch that would cost easily six times that in the U.S. -- if you could find anything equivalent.
