A lot of companies are involved in a lot of renewables tech research. That doesn't mean that any particular one is going to be profitable. The vast majority are going to be big failures.

Wave power's track record so far has been subpar to say the least. And looking at their diagrams, I can't imagine that they're not headed straight for the same fate. Even if we assume that their numbers aren't overly optimistic, their design looks like it would involve several times more steel per nameplate capacity than a wind turbine tower. And they're operating in a much harsher environment. No rotors, but they're dealing with major hydraulic pumping instead. It just doesn't look like a winner to me.

If it was my job to have a go at wave power, I can't imagine going for anything involving large amounts of structural steel or hydraulic pumping; I'd keep it simple and just go for a grid of cables (potentially a high tensile strength UV-resistant plastic), anchored at the edges to keep tension up across the whole grid, with the only slack available involving the grid pulling on regularly spaced springloaded reels (the rotation thereof generating electricity), with any combination of floats, drag chutes and weighs/anchors to cause the needed tug from the movement of water. No pumps, no hydraulic fluid, no large compressive-loaded structures, just a tensile structure that would be (proportionally) lightweight and easy to deploy.

But hey, it's not my industry ;)

I thought we argued on all the downloading stories that an IP is not an identifier?

It is not sufficient for prosecution.

First off, an IP address can be re-assigned. So you'd need an IP address and date/time to be able to link it to a specific ISP account.

Each account can have multiple machines behind it that may or may not belong to that account (depending upon the security of their wireless network for example or whether any have been cracked already).

So an IP address is not sufficient for prosecution BUT it can be a personal privacy issue.

Bennett Haselton spends 1341 words on what should be a 3 sentence summary.

If you want to know whether X accessed the mayor's dropbox (why is the mayor using dropbox in the first place) then you need to
a. get the IP addresses & times that they were used to access it
b. match the IP addresses to ISP user accounts at those times

Now, if the judge does not support you, personally, having access to the IP addresses then the judge can appoint a disinterested 3rd party do handle it. You are only interested in the ISP user accounts and whether those belong to lobbyists.

There! Done! And no need for Bennett Haselton's weird tangent on cracking via web browsers.

And from their numbers, it doesn't look like they're using a reasonable estimate for Chernobyl. There've been some ridiculous estimates out there from both sides, ranging from "only the couple dozen who died directly" to "millions".

One can look at the approximately 10% higher mortality rate within the exclusion zone to get a rough sense of the consequences, but without knowing demographics, it's hard to draw conclusions from that. Probably the best (peer-reviewed) analysis I've seen compared doses with the US military's mortality data from exposure to the nuclear bombings in Japan. You get a figure of about 4000 extra deaths with moderate confidence and 5000 with low confidence (the error bars can be in either direction). So very rough ballpark of 9k deaths, plus the first responders and the like.

Yes, even when you include things like that, nuclear's death toll is lower than coal, no question. But it's not as low as they make it out to be. Their bias is obvious.

The deadliest nuclear accident, Chernobyl, was caused by defense department testing.

Yep, nuclear disasters can happen from both man and nature. That's hardly a comfort. Will "defense department testing" cause the next major nuclear accident? Very unlikely. But there almost certainly will be a "next major nuclear accident" - we just don't know what form it will take. It's a "known unknown".

Whereas Fukushima was all user error?

No. But if you're going to include "dam-induced casualties from storms", then you should include "people spared from storms by dams" also, it's only fair. And thus hydro's death count would be strongly negative.

Perhaps it is possible to offset renewables in such a way that they can provide 90% of our power needs, but no one has ever done it.

Speak for yourself. I live in Iceland where over 99,9% of the grid is renewable (primarily hydro). 99,9% renewable baseload at that. There's even serious preliminary work looking into building the world's longest submarine power cable to export power to the UK.

Again, not saying that hydro is my preference - I've stated my preference above. Just pointing out that your claim is wrong.

(Concerning the power cable: I'd support if A) they'd only be adding geo plants and wind to meet the extra power need, and B) the government would tax the power sales to the point where the cable makes just barely enough profit to economically justify its existence... but I'm sure that A) they'd probably just dam up the highlands some more - who gives a rat's arse that we have some of the world's most abundant and cheap geo and wind power that could easily compete on the European market, hydro gives a tiny bit more profit margin!; and B) the government would hardly push back at all on power export royalties because, hey, JOBS! Jobs damming up the highlands!)

Close, but your syllable count is a bit off. Something like this would work:

fuck ink jet printers
fuck all those fucking printers
i fucking hate them

Technically, though, you're supposed to have a connection with nature for it to be proper haiku. So maybe something more like

ink jet printer rests
at the bottom of the bog
piece of shit printer

What world do you live in where mine shafts allow objects to fall for hours, days, weeks, months, or years at a time?

And FYI, this "weak force" is the reason your muscles aren't atrophied and you're stuck to this ball orbiting the sun. It matters.

They did. But first off, to correct the GP: Concrete does not release CO2. It absorbs CO2 (slowly taking back the carbon that was released during the cement's creation). So this messed up their balance equation. Metabolism was supposed to consume O2 and make CO2, while photosynthesis was supposed to consume CO2 and make O2. But with the concrete locking up the CO2, the output of metabolism was being locked up and not being converted back to O2, so the O2 levels declined.

It's a simple oversight, but one that we're very lucky was made on Earth and not on, say, Mars. More foresight could have caught it, but there's always something that slips through the cracks. A number of other issues showed themselves, such as unexpected condensation adding rain to areas supposed to be rainless, less light than anticipated making it into the habitat, certain inspect species proving incompatible with the environment while others proving to be pests, so and so forth. They also had big problems with wild fluctuations in CO2 by time of day and season - they didn't have a massive amount of atmosphere to buffer it, so levels collapsed during the day and shot up at night. A lot of people complained that the project wasn't focused enough on the science, but I think they learned an awful lot of important things that could prove critical if ever trying to grow crops on another planet.

(The psychological aspects and how the crew split into two bitterly divided factions is also a real cautionary tale)

So anyway: after the first Biosphere 2 experiment was terminated, they sealed the concrete and started another one. But the second experiment was more doomed by politics than anything else. The on-site management was foreceably evicted by federal marshals. Former biosphere members broke into the facility so that the people inside could know what was going on outside (in the process, ruining the sealed environment). And then a couple months later the management company was dissolved. Altogether the second mission lasted less than half a year. It was a total disaster.

Just like we stay away from active volcanoes.

Which is why 47 people didn't just die in a Japanese volcanic eruption a couple months ago? In the country with probably the best volcano monitoring on Earth?

Please, do go on about Ukranians. I want to hear about how they crucify children to torture their mothers for revenge.

Who's the actual target?

I once knew someone who was in military intelligence during the Cold War who had lots of good stories about where the intelligence to analyze came from. One good source was an undersea Soviet cable that the US had covertly tapped. Another was their predecessor to cell phones. They were analog and unencrypted, but they generally realized the risk and didn't use them anywhere near where there might be a listening post. However in issuing guidelines for their usage they apparently miscalculated on the fact that the signals also propagate up, believing that the low power transmissions would be too weak and distorted by the time they got to orbit to be demodulated. The US however had a satellite that could do precisely that.

The Soviets were also very good at covertly tapping US communications. They (and their Russian successors) also made good use of them in other ways. In the Chechen conflict, their leader Dzhokhar Dudaev stayed in communications with his contacts via short calls by satellite phone. The Russian solution to this was to create a system that would specifically recognize his phone, and mounted it to a HARM - the sort of missile normally used to take out radar transmitters, which homes in on a specific radio signal. It was the world's first - and only - "Anti-Dudaev Missile", and worked quite effectively.

embarrassed themselves by proposing obvious nonsense

Okay, I'll bite. here's a comparison of historic forecasts from skeptics and from mainstream scientists, versus actual measured temperatures. Who, exactly, is embarrassing themselves here?

It's long been known that the temperature of the thermosphere is highly dependent on what the sun is doing. It doesn't "store" energy, and there's essentially nothing above it to block it from radiating out into space. It also represents a mere 0.002% of the atmosphere.

It's not the thermosphere whose temperature people care about. It's the first few dozen meters of the troposphere that matters.

and it's about the coolant effect of CO2 in the middle and lower atmosphere, not the troposphere

You keep using that word. I do not think that it means what you think it means.

(Hint: the troposphere *is* the lower atmosphere - and if you define "middle" by "half of the mass" rather than "half of the altitude", it's that too)

Why is it "bullshit"? Do you actually think there's really no health cost to dumping PM, SOx, NOx, CO, VOCs, etc into the atmosphere (just ignoring CO2)?

Quite true. People complaining about randomness on the grid and uneven supply usually don't stop and consider that the grid already faces huge randomness from the other side - demand - and deals with it just fine. Baseload is indeed a problem, not a solution, and peaking and storage are interchangeable.

I think people focusing on storage are letting "perfect" be the enemy of "good enough". I think storage is the ultimate future, but we're talking long term. Mid-term, peaking is the answer. Switch over the lion's share of generation to renewables, get them as type-diverse and geographically-diverse as possible, use peakers to fill in the gap like we already do, and you've taken out 90% of the problem (at least on the electricity side - still have to deal with transportation and other anthropogenic emissions).
