Aug 7, 2009 - interesting stuff!

Aug 14, 2009 - diameter of the sun is 100 times the earth's? I think it's bigger than that.

warbuff1 Says:

Aug 14, 2009 - I think the bigger question is even if this was operational today,woud it really be used for the benefit of all humans?I think in the existing system we live in today,this would be abused by the governments,states like the US would use this very centralized power source to make their elite even richer.This is not a democratic power source,nature produces its energy locally.This thing would be run by a bunch of technocrats who would be the system's slaves and used to eliminate other power sources

Aug 23, 2009 - The sun provides me with all the energy i need. Im still on the grid and thats nice cause when i dont use any (like when im not home) the extra electricy produced is "going back" and bought by my company. Nice fellin I have when i can see on the meter I sold 1-2 KW on a clear sunny day when I was gettin taned on the beach..

Aug 30, 2009 - You are absolutely right... but why do we still live in a system using competition instead of common help? I do not talk about communist dictators or stuff, I talk about the utopia of an internationalist earth... Why wouldn't it be possible? I think that capitalism must come to an end before we can really evolve as a species. And maybe we could be able to live just like in star trek loll... But anyway, I'm studying physics to work on that.

warbuff1 Says:

Sep 1, 2009 - Thanks loafy,I used to know all this stuff,but haven't checked the numbers for a long long time and my memory is starting to fail me I guess.

Sep 2, 2009 - Yea and titruim is hard to come by- only a few kgs exsist and any point in time on the earth natrualy.. they have to make it sintheticly by firing nutrons at lithuim.. not as abundant as they say..

tobleronetobias Says:

Sep 2, 2009 - and i wonder whats going to happen to all those helium nuclei let off?? to me sounds like they should run a fission and fusion factory next to each other.. fission to split the helium into a titrium and deutrium.. then the fusion to form the helium again.. then it would be everlasting with no waste product whatsoever.. The real clean green job. (:

Sep 11, 2009 - He keeps pronouncing nuclear as nucular - just like president Bush.

TORSOPHUCK Says:

Sep 21, 2009 - Chain Reaction?

MarktheSharkSheehan Says:

Oct 4, 2009 - unfortunately we don't live in a perfect world yet, and although not perfect, competition has been proven to work

USSDaedalus Says:

Oct 6, 2009 - It's kinda scary that scientist can actually do all this... I know it has many benefits, but it's still pretty scary...

Oct 13, 2009 - Of course Helium will be stored underground for a while to deplete its dangerous radioactivity. One good thing is hellium has a really short half-life around several decades, comparing to Plutonium could be 250,000. You have a great imagination to think of putting a fission ad fusion factory together. The funny thing is hellium is not a fissionable material. It costs more energy to split helium atoms than getting energy from the chain reaction if you can think of some way doing that. :))

kogwin Says:

Oct 13, 2009 - what you have watched is also cold fusion. It 's "cold" because it needs relative lower pressure and heat requirement than the normal standard "hot" fission reaction. There are experiments trying to prove nuclear fusion happens in room temperature. However, most of those are failed due to insufficient evidence that a nuclear reaction has occured.

buhrrito Says:

Oct 28, 2009 - do we use nuclear fusion for anything? (U.S.)

simplic10 Says:

Oct 31, 2009 - "The sun is a ball of PURE ENERGY!" Crikey, is this really National Geographic?!

rowen898 Says:

Nov 5, 2009 - essentially creating the sun on earth! through newtons law of conservation of energy. The magnetics required to keep the fusion from expanding 100x the size of the earth is roughly equal to the energy the fusion process produces. Before fusion is viable we need technology to eliminate the large possibility of global extinction.

averageskill Says:

Nov 8, 2009 - this is not computer technology, where fitting more and more transistors onto a grid is the future. this is the equivalent of fitting a million bowling balls into a suitcase...it's just not going to happen here on earth....ever.....clean coal, that's the future....we have enough coal in the USA right now to last forever.
