RWE would like to shut down a few coal power plants that are no longer profitable in the current distorted market. But the government, the very same technically illiterate government that fouled up the market in the first place, declared t

Thanks for the link. With that paper in hand, I can say confidently that the Scientific American article is a flat out lie, starting from the headline. Chart S1 plots the distribution of the predicted probability for survival in four condi

Maybe we have? The article says "the other differences were not significant", but that does not mean there was no difference. It means "there was not enough evidence to reject the assumption that there were no other differen

This sounds awfully complicated, near impossible. You'd need a circuit that disconnects from the grid once it detects a brown out or black out, then produces a near sine wave all by itself, then re-syncs with the grid once it comes ba

Fictional archaeology isn't history, is it? Anyway, there are no experiments in history, therefore any "theory" is untestable. History is... I'm missing a word here, but historians are scholars , not scientists.

So, what does it mean? As far as I understand, science means to have at least one theory with some explanatory power, to test that theory by experiment, and, crucially, to discard the theory if it is invalidated by experiment. That quite o

Not if it was incinerated. That's definitely where the sludge should have gone, but it's also where paper waste could go. That would also avoid problems with greasy pizza boxes, window envelopes, and impossible to remove toner.

If you recycle paper, you end up with some sludge of degraded fibers. The sludge can be composted, it's just cellulose after all. Sounds like a good deal, doesn't it? It is, until weird coated papers get into the recycled feed s

Sounds like they set it just above the detection level, "just to be careful".

The same "nastiness" makes these compounds essentially non-toxic, too. Since nothing less reactive than oxygen radicals seems to attack C-F bonds, these compounds just sit there doing nothing. Which is what the report's sum

To recreate "little boy", you would need about 10 tons of natural uranium. Absent any better ores, you could mine that from coal ash, which typically has a uranium concentration of 10-100ppm. You really think that's limitin

So they are talking about a plant, soon to be built, that will capture about 50.000 tons of CO2 per year. Amazing! A single coal fired power plant (1GW) emits 12 million tons of CO2 per year. Seriously, this stuff won't work, and i

Scientific American is flat out wrong, compare[1]. (Someone who states that "a breeder creates more fuel than it consumes" has to be wrong about many things.) Common rocks contain about 13ppm uranium and thorium, which gives the

I have a radical idea: don't keep that data. You can still log accesses and aggregate them into statistics, just don't keep the IP addresses. You can still log IP addresses to detect DOS attacks or whatever, just delete the log w
