Sustainable Energy, USA and worldwide:

[up] The issue with that is that the reaction just doesn't produce nearly enough helium to fit the needs of modern industry (and it's used for just about every modern industry). This is because fusion is actually a very efficient process under ideal conditions (a single truckload of hydrogen could sustain a 1 GW fusion power station for a year).

So while it's possible that fusion reactions could be a source of helium, we'll still need to be mining it to meet industrial demand.
Wenn man nicht die Fresse halten kann, einfach mal Ahnung haben.
[up] I don't think the intent was to get rid of helium mining but having additional sources is always nice, even if they are insignificant.

A mix of both. Even insignificant amounts might be worth capturing and selling, depending on what the laws on emission of the stuff is.
Happy Lifeday, one and all!

These guys seem to think that there's no way around it without reducing consumption. That's a tough sell.

If there's less to replace it makes replacing the rest easier. Not the only way though. We could power the world on solar right now if we really wanted to.

[up][up]No we could not, unless you want to spend the night without electricity. We don't have the technology it takes to store the energy throughout the day and distribute it as needed. Otherwise, fossil fuels and nukes and such remain indispensable.

You can store solar power. There's some loss but you can actually generate power and store it in various ways. One of the more popular ones, if I'm not mistaken, is to use the excess electricity to pump water into a high container, from which it is then allowed to fall back down (powering a hydro-energy generator on the way) when the solar panels aren't producing power. As I said, there's some loss but it does work.

There are other ways to store energy, as well.

[up]There aren't enough valleys in the world to store all the energy we'd need. There are storage options, but they're limited.

There's a difference between 'can't' and 'would be expensive'. As best said there are storage options, and besides that it is possible to lay power lines across oceans. With a global power grid we could use purely solar power without significant storage. Besides, demand at night is much lower.

There are lots of technical difficulties with what you're suggesting (basically, Desertec's program). Electricity just doesn't carry over very well over very long distances. You gotta produce the energy locally, as much as possible.

it COULD be done though. I didn't say it'd be the most effective thing.

Jared Diamond is a sociologist who has recently gained a following, especially among people who are just getting into sociology. (I don't mean to imply that people who are already more involved in sociology aren't fans of his; I'm just saying that he seems to have gained a status as a sort of intro-level popular sociologist.)

He likes to write about the history and future of Western civilisation, from the perspective that our civilisation seems to be displaying many of the features that led to the fall of several empires of the past.

His popularity as an entry-level source is probably due to his accessible and clear writing style; man knows how to put words to a page.

Collapse is super relevant to this thread, who's read it?

Defictionalizing my title as we type!
Late to this thread, but if it wasn't mentioned, this is HIGHLY relevant: http://arstechnica.com/science/2014/02/giant-leap-for-nuclear-fusion-as-scientists-get-more-energy-out-than-fuel-put-in/ [1]
From the main page: "Once again, we're about celebrating fiction, not showing off how snide and sarcastic we are." When here, I am home.
Scientists have been trying to tame fusion power for more than 50 years with little success. Although the National Ignition Facility, a $3.5-billion operation, was built for classified government research, half of its laser time was devoted to fusion with an aim to accelerate research. Zulfikar Najmudin, a plasma physicist at Imperial College, said: “These results will come as a huge relief to scientists at NIF, who were very sure they could have achieved this a few years ago.”

That's honestly a bigger budget than I expected them to have. Of course, I'm of the opinion that somewhere in the neighborhood of half the national budget should be earmarked for scientific research, but still. They're making good progress, all things considered. Hopefully they can get more attention, and thus money, and start to speed this up.
@Best Of: I can't really say I'm a fan of most pop-science writers. But especially the political/sociology/evo-psych ones...Such crappy research and crass preaching. They're just selling what people like to believe.

Here's an interesting thing. Great for carbon sequestration (actually carbon-reuse). Produces usable jet fuel for around $3 a gallon from seawater. http://www.nrl.navy.mil/media/news-releases/2014/scale-model-wwii-craft-takes-flight-with-fuel-from-the-sea-concept

Weird emphasis in the article title. Talks about model planes, like that's the important part, not the revolutionary fuel source.

That price is a projection, it's not commercially viable just yet.

Don't see what your saying, seems to me the 'fuel from sea' part carries weight
