Oddly, I find Wi-Fi to be the only wireless technology which does work reliably. Bluetooth? It's pure bollocks, it never works. Well, that is, when you're trying to do anything the least bit fiddly. And they permitted all kinds of things which abuse the shit out of the spec to call themselves bluetooth, like PS3 controllers. And my problems with cellular technology are legion. But Wi-Fi tends to just keep on ticking along for me. Routers, those shit themselves, but completely and not just the Wi-Fi.

You can have all the same equivalent problems with normal Ethernet, though. Many vendors still sell ordinary 100bTX(etc) chipsets which are total garbage, and people still buy NICs using them and stick them into their machines. I have a whole raft of sketchy tulip clones here because they were $1/ea some years ago at Fry's, back when that was still a really amazing price and not just what you'd expect on eBay. They work OK if you only put one of them in a system, which pretty much crapped on my plans for them, but over the years they've occasionally come in handy. Problem is, PCI is goin' away...

Well no. My vacuum and microwave are both brand-name products which seem to have adequate shielding, they do not seem to negatively impact my 2.4 GHz Wi-Fi in the least. In case you're wondering, the vac is a Dyson.

It isn't. Most devices don't use the generic driver, even when it would be better than whatever they actually did.

What sucks about Wi-Fi is that when you have a lot of networks near one another, they crap on one another harder than they are supposed to. It takes extra-special care to make this not happen, and then any dillhole who brings his own battery-powered AP with him can still totally hose your network. But otherwise it mostly works, and often better than the other stuff that's supposed to be better. I had way less radio-related problems when my WISP used Wi-Fi than I do now that they're using some custom CDMA crap. No weather problems either, even though I'm more than five miles from the site. It proves nothing of course, except that the Wi-Fi is more mature technology than whatever they were using.

Now, I have yet to try Chromecast, Miracast etc. but I'm starting to think harder about that, so maybe I will finally learn to hate Wi-Fi. But in general, the only real hardship I've had is with chipsets whose drivers don't support master mode under Linux. This taught me to buy intel and Atheros. Even then you don't get a guarantee, but odds are great and you can always check ahead of time. The thing is, that's good advice anyway, both what to buy and what to do before you buy.

But that just costs more energy. If you've got unlimited energy, why not just make fuel from seawater? I mean, we should be treating our crap better anyway because we need the resulting soil anyway, but even so.

Nonsense. That's a ridiculous idea no matter how you slice it. Nature might occasionally slip DNA from one family into another, but it never produces a big fat protected monoculture of anything like that. We have the opportunity to ensure the success of things which would better not exist at all, and you imagine that this new ability is somehow less dangerous than what we have been doing, which is limited by the effective checksum functionality built into all familiar life? Yeah okay there buddy.

Yeah you sound like you know what you're talking about, except you don't. BP is patent trolling to prevent Butanol from happening, when they could be selling it. Why wouldn't biodiesel be subject to the same sort of machinations?

It's okay, because algae doesn't care if you use salt water. So you use wind, solar, and solar thermal pumps to move seawater inland. There's no shortage of that.

Yes, I've read them, I know they only did one decent-sized test.

Who has the land? Who has been trying to do it?

Clearly you and all the people you have allegedly been following [citation?] failed to read and understand the report, which specifically says that this will happen if you try to seed the ponds with specific strains, but also that it's a fat waste of time because the strains which are most efficient in the laboratory are not going to be the strains which are most efficient in your pond, year over year. The strains which are most successful in your region will naturally dominate the ponds no matter what you do. The only way to select for strains that produce a lot of oil is to make producing a lot of oil a survival strategy, and it isn't that. Maybe someone will come up with some kind of additive that convinces the algae that it is, and then you can have your even-more-efficient-than-necessary strains.

They have a system that works. They're not interfering with it. Indeed, BP is suing GE to prevent them from interfering with it.

The thing which prevents biodiesel-from-algae from happening even though it would be profitable now is that you can't get the permits you'd need to do it. Even if you did, by the time you actually got moving, the next administration would come along and quash it. It takes cooperation from government to enact such a massive project, and government is currently cooperating with Big Oil — indeed, it's peopled by it to sufficient degree to permit them undue influence. In the past the federal government has been happy to permit BLM land (for example) to be exploited for coal and oil in extremely destructive ways, to say nothing of the clear-cutting that goes on in the parts which still have soil enough to support trees. But they've been resistant to solar projects, citing concern over environmental impact. Now that is comedy.

There's nothing magical about oil from algae as a feedstock for transportation fuel, and it would make a significant positive difference, and we can do it. We do have the technology. Moving water around between ponds is a well-solved problem. We do more complicated things all the time, and for much more specious reasons than to reduce environmental impact.

I didn't make a specific claim about algal microbiofuel from sun to tank.

First, you cite the comment which justifies your claim. And, your laziness. I provided a citation. It's a summary, and it contains its own summaries, and you can search it.

I'm speaking in generalities. This was a survey of lots of people, not just slashdotters. You're being obtuse. Is it deliberate, or are you just frothing?

In order to come to that conclusion, they only included technologies known to support it, and completely ignored well-known and proven technologies which disprove their point. Therefore, there is no validity whatsoever to the study, and you should summarily ignore it in turn.

[citation needed]

That might be true for butanol production, and if so, you should say so. But as for Algae grown in open ponds, it's a complete falsehood, and the linked report makes this clear. In a reactor, where it doesn't have to compete with other strains, it might work. But if you put it in a pond, another algae is going to come along and outcompete it, since it's not putting its effort into producing what excessive lipids (for its purposes, anyhow.)

The linked report is especially relevant to the particular point you raised because the goal of the program on which it reports was to study the breeding and application of high-lipid-production algaes for the purpose of production of biodiesel fuel, and what they determined (and indeed the thrust of the summary) is that there was simply no point. You put out the water, the algae shows up, you stir the algae, you achieve peak production with very little effort. The only thing that's really changed is that peak insolation has increased since the report was written, so you might need to shade your ponds.

That is wrong, and you are either ignorant or lying.

You put the feedstocks in a big bag, basically like the ones they use as water tanks. You run the escaping gases into a system where they're pressurized to appropriate levels, the methane is separated with a membrane, and then compressed. This is already being done at a profitable level on a number of farms across the country. The lowest-hanging fruit is pigshit (what a great sentence) because it is very hot so it cooks quickly, and it is a major environmental problem. The shit is normally just pumped into open ponds where it sits and stinks, and then eventually either flushed into some shitty waterway or flushed out of the pond by flooding.

Only if the people implementing the system are total assholes. Algae is a plant, and if you put out some water and stir it, you get algae. As it turns out, there's no point in trying to select varieties of it either, which is probably why we aren't spinning up production: nobody has figured out how to profit by patenting the algaes yet. As it turns out, nature has produced more different kinds of algae than we know what to do with, and the most productive algae for your climate just miraculously shows up and colonizes your water for free. What's more, the water can be of any salinity up to oceanic levels, and can contain substantial contaminants.

People don't have opinions on science issues which aren't politically charged.

And I am quite tired of people ignoring the language.

So it must be right!

He won a competition that he decided he was having. Now he gets to feel smug. That's its own reward.

This battle has been lost, and you will now need a threaded email app.

By which what is really meant is "into the air". What part ain't burned and released real quick-like (producing soot in the process, yay cancer!) is set somewhere to rot anaerobically where it produces the maximum possible methane and CO2 and releases it into the air to cause us all problems.
