Comment Re:Efficiency should kill it (Score 1) 284

There's lots of electricity in things that aren't in your house, in street lights, shops, factories etc. etc.

The total energy per capita for example is over 5kW in the UK for example (10kW in America), check out the final column in this table:

http://en.wikipedia.org/wiki/List_of_countries_by_energy_consumption_per_capita

Things like mobile phones are completely irrelevant really, and laptops are pretty much irrelevant.

I saw a number which was ~2kW by an academic for the UK, that IRC would have been electricity only (presumably he took total electricity supply and divided by population).

These devices use very little power.

A typical person in the Western world uses, on average, 2+ kW. That's not 2kWh per day, that's 2+ kWh EACH AND EVERY HOUR.

These devices that are proposed to be charged wirelessly are usually just a few watts, about 1/1000 of what the person is using; so even if the power efficiency halved for those particular devices, it would make essentially sod-all difference.

The other thing is that in many cases if it's easier to recharge, then you don't need such a big battery; batteries are incredibly expensive compared to wall supplied power.

You have a very rosy view. And that's not what happened in this case; for example. There are a large number of admins that will quite happily remove primary sources, even though the actual policy is much more nuanced, and ALLOWS adding material from twitter and blogs to be used in cases like this; a clear public statement by an author that something or other wasn't his inspiration, while it cannot be taken as proof of that, could easily have been mentioned in the article.

Like:

blah says this,[ref1] somebody else said something else,[ref2] but the author disagreed and said something else.[ref3]

Protip: sanctions like you describe are usually more to do with other users/admins ganging up on someone, not so much not what they do right or wrong.

It really doesn't really work like that, although it might seem like that if you're a novice.

The admins have a rough set of rules they actually use, that are somewhat disconnected from the real rules; admins rarely read the rules.

The way it works is that each admin basically makes a decision what the rules 'really' mean, and any given admin will hardly ever override what another admin decides (they call this 'wheel warring').

The admins, by and large, have a pretty hazy understanding of the rules; usually it seems like they've just read the title of the rule, and imagined what it said, and they are in deep contempt of anyone that really does understand the rules (they call that 'wikilawyering' and it's an insult.) If you quote the rules to them, you will get absolutely nowhere. The admins will very often apply rules in a way that the rules themselves explicitly say is not what they mean.

I once had a really sore throat, it hung around for a few weeks. Seemed to be some kind of yeasty type thing.

It disappeared when I had a pack of sugarfree gum, peppermint has antibacterial properties, and the xylitol tends to help bacteria wash away.

It felt about 50% better immediately, and 80% better in 24 hours, and was gone in a couple of days.

But i tried it again with similar symptoms a few months later and nothing happened.

I suspect it did do something the first time, but I wouldn't be shocked if it was just coincidence or placebo.

It didn't look like there was anything new in his paper to me. When he wrote it, the theory of cryptography would have been much further advanced than that, the idea that cryptographic strength can at its best go up exponentially with key length is pretty obvious.

It didn't look like he'd come up with a strong crypto system either; I suspect that the only reason anyone even looked at it was because he was a professor of mathematics and so they would have given him the benefit of the doubt, but the contents were very amateurish, and I doubt Campaigne would have had trouble cracking it.

If I've understood it correctly, it's an embarrassingly weak LINEAR encryption system, which is trivially crackable with matrix operations in N bits of known plaintext and encyphered text where N is the key length.

Almost all of the people that have looked at the evidence for AGW carefully enough with any kind of open mind (including some skeptics) have come to the conclusion that it's almost certainly happening. There's virtually no scientific controversy, but that doesn't stop people trying to give the impression (often very successfully) that there's a lot of controversy.

But there isn't.

This fact, that there's little controversy over the basic facts, is not well known in America in particular, and that's really pretty sad.

Its a false idea that in absolute terms space tourism releases a lot of CO2.

That's a bit like saying that Concorde was a massive creator of carbon dioxide. While it produced a few times that of a 700 series flying London/NY, in global terms it was utterly insignificant. And that would have been true even if the aircraft had sold in quantity, there just weren't going to be enough aircraft.

And space tourism is the same, nobody is going to be building the hulls in sufficient quantity for them to EVER use a globally significant amount of CO2.

The real battle for CO2 isn't in these exceptional activities it's in the everyday. Driving, heating your houses, the energy embodied in food. These are massively bigger because you do them everyday, for your entire life, as opposed to for a few hours, on very, very rare occasions.
