- purag66, on 05/13/2009, -1/+80We've been hearing that "fusion is just around the corner" since the 1960 World's Fair .
- alackofcolor, on 02/12/2008, -2/+55As a graduate student in physics, there's a common saying that nuclear fusion is always 20 years away.
- isuisorisuaint, on 02/12/2008, -3/+46how did i get here? i thought this was a shaving post.
- MikeL123, on 02/12/2008, -1/+38There was room here for only one Back to the Future reference, and you just blew it with that.
- tonicboy, on 02/12/2008, -3/+38Come on now, give them a little credit. Even the environmentalists are on-board with fusion because if how clean it is. Hell, for the most part, they're even on-board with fission because it's still cleaner than coal.
- esteskid, on 02/12/2008, -0/+30Fortunately for you they covered this in the article
'In a world where we're all used to hearing that "Fusion power has been twenty years away for twenty years" hearing that it's five years away is pretty remarkable.'
Try arguing with science like that ! - d3mag0gu3, on 02/12/2008, -12/+40What the hell does this have to do with Obama? Knock it off guys. Obama articles only!
- jls33fsls, on 02/12/2008, -1/+29I feel like this has happened before...
- BigManOnCampus, on 02/12/2008, -13/+41Greenpeace will whine about the waste. I'll be sure and tell them in a high-pitched-voice how clean it is.
- DrDragun, on 02/12/2008, -1/+28It looks so simple in the drawing... until you read "Linear Implosion System"
- YevS, on 02/12/2008, -1/+22From the General Fusion site "General Fusion has patented this technology and believes that a reactor working on this principle could be built at a much lower cost than using the old magnetic and laser fusion approaches"
Meaning it should work in theory, but they need to build it first.
A working prototype in 5 years? Sure
Blueprints for a commercial reactor in 5 years? Not very likely
The sience behind it is very exciting, combining the MF and the ICF approaches to create a vastly cheaper solution than either of the two. The core being a "3 meter diameter spherical tank" I can see this being used by the navy... - KraftDinner101, on 02/12/2008, -5/+26Until Greenpeace admits that genetically engineered crops are fine to eat and have in fact saved millions (perhaps a billion?) of people, I will forever have no respect for them.
- garfonzo, on 02/12/2008, -2/+23Star Trek Script:
-- "Captain, the (tech jargon) is failing!"
>> "We must bring the core to (tech jargon)."
On screen:
-- "Captain, the linear implosion system is failing!"
>> "We must bring the core to thermonuclear conditions." - tonicboy, on 02/12/2008, -1/+18"but there are many domains (for instance autos) where I'm not sure if they can play any role at all" ever heard of electric cars?
- krystofr, on 02/12/2008, -1/+16Five years??? No way. You're forgetting about the extra 10 years of bureaucrats trying to figure out how to TAX THE HELL OUT OF IT!
- twazzer, on 02/12/2008, -0/+15there already is a fusion weapon- its called the hydrogen bomb
- MacEnvy, on 02/12/2008, -0/+14As someone who reads science articles, there's a common saying that nuclear fusion is always 20 years away.
- KraftDinner101, on 02/12/2008, -0/+14In this house we obey the laws of thermodynamics!
- greenlight2001, on 02/12/2008, -0/+13WITH 17 BLADES!
- crapmatic, on 02/12/2008, -0/+12Well, technically speaking, according to Back to The Future it's only 7 years away.
- sgiffy, on 02/12/2008, -1/+13And it will happen again.
- kingraoul3, on 02/12/2008, -0/+12How many "Star Wars" do we have left? I'd like to reserve one for a later comment.
- yohnstoppable, on 02/12/2008, -0/+11You're doing it wrong
- scabbers, on 02/12/2008, -1/+12Except they haven't built anything, so the heat captured isn't significantly greater than the energy used to run the device, because the device doesn't exist.
- fridenstrom, on 02/12/2008, -0/+10And don't forget to reverse the polarity !
- inactive, on 02/12/2008, -1/+11Did you catch this part of the article:
"The heat captured is significantly greater than the energy used to run the device and the only byproduct is helium and other harmless gasses." - NetCaptive, on 02/18/2009, -3/+12Yeah, but can they generate 1.21 gigawatts with that bad-boy?
- centran, on 02/12/2008, -0/+9At least he's honest
- tfstone, on 02/12/2008, -1/+9First the cheeseburger in a can and now this! Where will it all end...
- rowlodge, on 02/12/2008, -2/+10perpetual motion inc. investors wanted.
- NeoCortex, on 02/12/2008, -1/+8Personally, I can't wait to get a Mr. Fusion installed in my DeLorean.
- hyaena, on 02/12/2008, -0/+7Nuclear energy is used to create this crazy thing called electricity.
- garryw, on 02/12/2008, -0/+7Or ignite Jupiter and have a brown dwarf nearby. Cut down on night lighting.
- otakushark, on 02/12/2008, -1/+6I remember doing a report in college on how fusion should hit the self-sustaining point in about 15 years. That was in 1978, and we still haven't hit that milestone. Keep researching it, but not at the expense of other alternate sources of power that are clean and practical to build right now.
http://www.newscientist.com/channel/fundamentals/d ... - ApokalypseNow, on 02/12/2008, -1/+6Not portable enough to weaponize - if we can make it smaller and find a way to direct and funnel plasma from the fusion reaction, then maybe we could make a flamethrower or something out of it. A better way would be simply to use the energy output from it to power more conventional systems, or the new Navy railguns.
- Jaliyl, on 02/12/2008, -1/+6You are wrong, this isn't just a site for Obama articles, Anti-Hillary articles and Anonymous/Anti-Scientology articles are allowed too
- 4degrees, on 02/12/2008, -0/+5will have to wait for the Mr. Fusion model.
- moskaudancer, on 02/12/2008, -0/+5It has a very "reverse the tachyon beam polarity" kind of sound to it, doesn't it?
- SPRFRKR, on 02/12/2008, -0/+5Have you checked the Containment Field? Sometimes it gets out of phase and you need to hit it with a hammer.
- fyngyrz, on 02/12/2008, -1/+6"We've yet to see if fusion is even viable."
Step 1: Wait until daytime
Step 2: Go outside
Step 3: Look up at the really, really bright round thing (just for a moment.)
Fusion has now been demonstrated as viable to you. - norman619, on 02/12/2008, -5/+9Sure they are. It's nuculur. That means evil. That's all I ever hear from those clowns.
- Tiak, on 02/12/2008, -0/+4You realize this optimistic artcle came from a site called "Eco Geek" right?... The environmentalists don't seem to have a problem with it.
- inactive, on 02/12/2008, -1/+5This will never work without government oversight & money. As if anything good could come from a rich, job creating venture capitalist investing in
innovation which could end dependance on fossil fuels and completely change the world. CALL THE GOVERNMENT!!!!
(sarcasm) - ggnictee, on 02/12/2008, -0/+4I will remain cautiously optimistic. We've yet to see if fusion is even viable. That being said, they did do it that one time (even if it took more energy to make it go then you got out) and a working fusion reactor would help with lots of problems. It's always been a bit of a geek fantasy. That Fusion (well technology in general) would ride up on a big white horse and save us from ourselves. That being said, I have a friend at Los Alamos and he always just says "almost, sooo close, almost there"
Oh well, here's to hope: the last thing out of Pandora's box. - mattsegal, on 02/12/2008, -0/+4its called "The Saint"
- ApokalypseNow, on 02/12/2008, -0/+4Just remember that half-life is inversely proportional to radioactivity - an instantly-lethal REM count would only last a few weeks, while a kill-you-so-slow-you-think-it's-a-career REM count could take decades to go away. If the half-life is in the centuries range, then it probably isn't going to be terribly unhealthy, especially considering what we have since learned about how much radiation we can take.
If you just want to play with the radiation involved in a weapon, just salt it with different metals - if I remember right, salting a nuclear warhead with gold will make an area uninhabitable for about a month, tops, then it's fine. - sugarkang, on 02/12/2008, -2/+6this is like duke nukem forever.
- theworldisflat, on 02/12/2008, -1/+5You are trying far to hard.... a successful BttF reference doesn't usually need much.
- LuckyASN, on 02/12/2008, -0/+4And it'll be a dangerous mission. Let's send ensign ricky.
- funkytaco, on 02/12/2008, -0/+4The world's first helium balloon/fusion factory?
