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 th…

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 o…

"When the battery is discharging ... positively charged ions shuttle from the anode to the cathode" I thought that electrons shuttle from the anode to the cathode.

I never understood the animus against saving. Saving just means you have produced more than you consumed, and I admire that.

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 fo…

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 tempe…

I searched on the words "vapor" and "vapour" and found nothing. I also search on the word "water" and found nothing relevant to my question.

Sorry, I can't click through to that article -- when I dismiss the pop-up, the tantalizing "Climate Shock" headline disappears. I do say that all humans require energy to survive, …

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 …

Likely yes, but please be careful that the remedies do not cause more severe difficulties than the problem itself.

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 posti…

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" (loos…

In Lima Peru the bus drivers pay spotters on the street who report flow conditions by cell phone.

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.
