    Eric mentioned that his simulation cannot be paralelised.
    I am guessing INCITE can be only implemented by a lot of parralel computer cores.
    So there is no speed up by running a serial task there, because you could use just one computer core.
    Its better to run on a GPU which has more serial powe.
    Of course dont forget that most GPU’s are also implemented by using several cores in paralel,
    so you should choose one that has the fastest core, instead of the most teraflops.

    Well this will happen in the end no matter what the people will do, and even if noone will be present to observe.

    Seems to be quite extensive.
    One issue I did not see adressed is that putting sequestering CO2 into ocean would make it more acidic.

    Wont seeding oceans with Iron generate an algae bloom? It produces an opposite effect as a result.
    I dont remmember the exact process, but basically it creates oxigen deprived zones due to decomposition, I think.

    I saw the observation elsewhere that after the ’81 oil price spike it took 5 years for new supplies to come on line.

    I almost pity the oil explorer/driller/developer companies; just as their multi-billion dollar investments are coming on line, FF will render them virtually worthless. So sad! :down: :ohh:

    So think what would they do to stop it?

    It seems you are right:
    “The modern belief that especially medieval Christianity believed in a flat earth has been referred to as The Myth of the Flat Earth.[1] In 1945, it was listed by the Historical Association (of Britain) as the second of 20 in a pamphlet on common errors in history.[2] Several scholars[3] have argued that “with extraordinary [sic] few exceptions no educated person in the history of Western Civilization from the third century B.C. onward believed that the earth was flat” and that the prevailing view was of a spherical earth.[1]”

    Its good to be skeptical, even of the skeptic 😉

    Great news! I hope their success will mean that other alternative fusion approaches will be brought into focus,
    and the tokamak will get kicked into nuts ($$$) ! 😉

    Some interesting points here:

    Basically oil producers do not want the production to catch up with consumption. As a result we have artificial peak oil.

    Which is the problem; there are uber-editors who can remove or block what they dislike, tho’. There are lots of politically sensitive sites where one viewpoint is instantly attacked and removed by other / majority consensus “editing”, and sometimes it’s subtle alterations of material to make it look goofy. Wiki is a battleground.

    While I agree with you that wiki is a battleground, I think the battles should be fought and won.There are a lot of editors that support only mainstream science, anyone can add content and fight for its preservation, if there is enough motivation for that.
    An annotation that a specific article does not match scientific consensus might be offensive, if its true it should be carried proudly, until times change.
    I would really love to see an article about QGrav in wikipedia. I would write one myself, but I am not a physicist, and even my understanding of fundamentals is mostly sketchy. This is why I usually rely on others Criticism, and I expect any Criticism to be correctly addressed.

    If you mean quantum gravity there seems to be many different theories there.

    As I understand basically quantum gravity is a name for the theory of everything. So is AF Mayer

    Does this teory have a name.

    I think you’d see a recycling of the long distance power lines. The copper in the wires will be worth more and more as the BRIC nations (Brazil, Russia, India, China) continue to increase consumption. The perfect place for a FF device would be the endpoint in the cities where all the transformers are, stepping down the voltage.
    Also there will be a need for more land. The strip of land the power lines occupy will be more valuable, wasting it on power distribution won’t be reasonable.
    I still like http://www.nanosolar.com, but they’re not real until I can go buy some of their cells — and I can’t today.

    Well another point for FF advantage. But this would require decentralizing the infrastructure which is also a huge amount of work. We are talking about that more in a different thread. Look at the end.
    https://focusfusion.org/index.php/forums/viewthread/181/P45/

    Nanosolar is sold out for this year, but they are ramping production to unprecedented levels, so I would expect you to be able to do that in a year or two.

    Unfortunately the “save the world” technology always looks just around the corner. This is why I understand the politicians who are pushing for awfully but proven technology implementations instead, like fission. This is why practically all the wind turbines in wind-farms are old-school design, when there is a huge potential in new generation of wind turbine designs.
