One step closer to fusion power

The Funniest History Of Japan You Will Ever Watch

poolcleaner says...

Mario and Son Goku: FUSION!!!!!!!!!!!! History and its micro miracles.

And don't forget the robots... which will one day take over the world -- and only brave, hypersexualized Japanese high school students in giant mech suits can defeat them!

Or be raped by demons and/or tentacles and/or demons with tentacles. Japanese game shows and poooooorn. THE END.

Bernie's New Ad. This is powerful stuff for the Heartland

JustSaying says...

I like Bernie and it's not just because he's the fusion of two of my favourite Sesame Street characters. He seems reasonable and less corrupt. But this ad? Meh.
Maybe it's because I enjoy the idiot circus boy too much.

The Wendelstein 7-X fusion reactor is insane

kceaton1 says...

As others have mentioned there are indeed still major issues to solve. But, they are slowly crawling to the answer (for some reason the US has just a "little bit" of interest in this--though if they go ahead and name their scientists as the sole awesomeness that thought how to make this a reality one day... I will truly hate my government for sure...

Hopefully, this reactor can give us some good data (and also hopefully was built with new processes across the board; again giving the scientists more data) on what's working better and what's failing either worse or @the same rate... There are about three main issues that need to be solved before we can call it "somewhat quits" (but, even after that, this would be a machine that needs a careful eye and constant monitoring).

I'm looking forward to the International Committee's Fusion Reactor in 2019~, called: ITER. It'll kind of be the "LHC" of the fusion world... They probably will figure out the issue with radiation destroying/eating away the guards/shields on the insides for the plasma.

These things are definitely awesome to see...

The Wendelstein 7-X fusion reactor is insane

Spacedog79 says...

Good luck to them, they'll need it. What is easy to forget with fusion is that they are still miles off reaching break even in a sustainable fashion. Moreover there are so many conflicting engineering requirements (super cooled magnets next to super heated plasma anyone?) that it isn't just a linear progression of difficulty to reaching break even, it is more like an exponential curve.

I don't think it will ever work, and with LFTR in development by the Chinese I don't think it is necessary either.

Nuclear energy is awesome

Nuclear energy is awesome

Fusion is well within our reach. It just doesn't have the funding (and therefore the fast research/development cycle) because the oligarchs are not done selling us fossil fuels yet.

Nuclear energy is awesome

ChaosEngine says...

First up, it's not 500 million years. Nuclear waste (typically Plutonium 239) has a half life of around 24000 years, an eyeblink geologically. Even if it wouldn't be too flash for life as we know it for a while, the planet will be fine, and life will recover.

But yeah, there are undeniably problems with nuclear energy, which are addressed in the related video (http://videosift.com/video/Nuclear-energy-is-terrible).

We have essentially 3 choices:

1: ditch our energy rich lifestyle and go back to an agrarian economy with no cars, internet or whatever. This also means ditching lots of really nice stuff, like medical technology (drugs and MRI machines don't grow from pixie dust). Pretty unlikely, IMO.

2: Accept that the eco-system is basically fucked and learn to live with climate change. Depressingly, this is probably the most likely scenario.

3: Invest heavily into other energy sources. And, like it or not, that's got to include some form of nuclear. Renewable (solar, wind, tide) etc, will help, but they won't cover all of our energy needs and they have their own problems. So ideally, it's fusion, but practically, thorium seems the next best bet.

This is absurd. Current pollution could wipe out our speices and maybe all the animals... but the planet would survive and could replenish. Cover the place in radiation for 500 million years and its screwed.

I'm not against new forms like the end of the video talks about but sticking the nuke drug into the problem with the hopes that maybe someday we will have a treatment is a stupid crack pipe dream.

Real Time - Dr. Michael Mann on Climate Change

Asmo says...

As a person who has solar on their roof, our bills have shown a slight decline (and I live in a tropical location with no obscuring of the panels), but that doesn't offset the cost of production (both in labour and energy input which is mostly supplied by carbon based sources). I run a 6 KW/h array which is slightly overclocked as we are capped at 5 KW/h input to the grid (at 8c KW/h sell, 36c KW/h buy). I'm looking at a ROI in ~11-15 years

There are also many studies (and not just from people who are pro nuke or anti-climate change) showing that solar PV in general, and rooftop solar specifically, is small potatoes in terms of energy returns, even when considering possible future gains in panel efficiency and storage technology.

I am not bashing solar because I don't like it, I spent the money to get an array on the roof because I think we do need to do something, but I'm not kidding myself in to believing that we're saving the planet when the vast majority of solar PV going out these days is manufactured in countries that emit enormous amounts of carbon and pay people peanuts to do the work... When, as you say, solar is heavily subsidised or has rebates offered to drive take up.

Nuke is expensive, but it returns far more energy than is invested to build it. Hydro, similarly (although Cali etc shows why hydro might be a dead end in this changing world climate). We can invest an enormous amount of time in half measures, or we can do it right, at least until we crack large scale fusion power production.

If it worked as well as it's hyped to do, huzzah, happy days. But so far, the boom is mostly hyperbole. At the very least, f#ck off subsidies/rebates etc to households and instead build huge solar PV farms with helio tracking arrays which make a better return on energy invested and basically give far more bang for buck. Or sink it all in to wind and cut back on PV. It's a feel good technology with hidden baked in carbon costs that is lulling us in to a false sense of security.

As a person who has had a solar system on their home for 9-10 years, let me say you are WAY off.
First, my system paid for itself in savings in under 8 years, and I missed out on a lot of rebates available today. My system should have another 10 years before I need to do major maintenance, by which time there will almost certainly be cheaper, better units to replace mine. In short, my system will save me from paying for around 10-11 years of energy costs, or to put it another way, 1/2 of my energy cost for a 20 year period.
I absolutely hate reading people talk about how bad solar is, and how it's not economically viable, when I know they are 100% wrong on those points from personal experience, not from anecdote and third hand miss-'information'.

Second, on top of the savings, I also saved thousands of dollars on lost groceries because my refrigerator doesn't stop working when the power goes out, which happens here around 1 week per year on average. My lights never go out, unlike my neighbors.

Is Climate Change Just A Lot Of Hot Air?

newtboy says...

Yes, you did say all that, but you also said none of that is a problem, at least not one to be really worried about. To me, that sounds a lot like climate change denial 3.0, where 1.0 was 'it's not happening at all, don't panic', 2.0 was 'it's happening, but it's natural and normal, don't panic' and 3.0 is 'it's human caused, but no problem, don't panic'. All of those are arguments designed to stall, not to be correct. If I'm reading you wrong, I apologize, but I've heard that argument before from those definitely in that camp.

If the IPCC says it won't be disastrous, yes, we would disagree, because I say it already is, and so have they in their summaries of their last few reports. Just abnormal drought alone is disastrous in many places worldwide already, as is increased flooding in some areas. I did not read the entire PDF's, only what you quoted because they were only linked as downloads/files, and I don't download files from sites I don't recognize.

I linked the first google search pages that came up with water/glacial data, not the other dozen that said the same, or near the same thing, not the NOVA on glacial retreat that said the same thing, not the movie on the same topic with photographic proof of the retreats-Chasing Ice. You ignored that they did list their source for the 2/3 of Chinese cities low on water and the 50% loss of glacial mass per decade as the Chinese military and claimed they were source less so easily dismissed.
As for the diatoms and shellfish, I've seen numerous studies on them, and again just grabbed the first one that came up in a search with data. You seemed to dismiss it as well, but it's not alone. In one snail study I saw, the woman said the last few years it had become nearly impossible to get measurements because the snail shells literally turn to paste in her fingers and weighed nearly nothing! I'm glad to read now that you don't disagree that it's an issue, you only think it's not severe?

I'm not holding my breath on fusion or fission, we've heard the 'we're only 5 years away from fission/fusion' line before about as often as 'Iran is only 2 years away from having a nuclear bomb', but we can agree on wind and solar, except I say it is great for base load, you just need to pair it with micro hydro storage (pump water uphill with surplus solar/wind, then run micro hydro at night). Small solar/wind also decentralizes production, safeguarding from terrorism, and is quite cost effective. Mine paid for itself in well under 10 years.

My issue with your position is that what we do today just with CO2 production reduction won't really effect the atmosphere for 20-200 years (the accepted lifespan of 65-85% of atmospheric CO2, the remaining 15-35% takes thousands of years to be trapped) and that's only IF the ocean CO2 sink continues functioning, so we're already well past the point of avoiding moderate climate change. Without quick action, feedback loops like methane and/or ice sheets melting make the problem exponentially larger and difficult/impossible to manage at all. It may already be too late even if we cut to zero CO2 tomorrow, but it's certainly too late to avoid more, massive, unsolvable global issues if we don't even mitigate them before 2050.

Let's not get into the quagmire of global dimming from sulfur in coal actually mitigating a large part of expected global warming by reflecting sunlight. I've yet to hear a plan or study involving that variable.
