    Zara, there are billions of neutrinos passing through you right now. don’t worry

    Now hang on. Skin exposure to Ammonia causes severe burns. how can you say it is safer than gasoline?

    And, don’t tell me CO2 is the nastier alternative to NO2, in combustion products.

    anyone care to inform them of reality?

    I propose we move this matter to a committee, to study the question of whether a bureaucracy can possibly have the agility required to take action on the issue: of whether climate change/ global warming is off topic for this forum.

    if i remember correctly, Eric said contents should be kept above 1000°C, between shots.

    taking attention away from Rossi is actually kinda easy: don’t use nickel plate when you want to study bulk properties of nickel.

    but i digress.

    lots of people have answered, “i’ll wait for the peer-reviewed articles” and otherwise look away, as though *any* new technology for power generation has about the same credibility as perpetual motion machine. “if this were true, they would already have won the nobel prize” is another easy dismissal.

    To those who say, “move over, old man. The world belongs to the young,”
    I say, “I am not ready to go, yet, thanks. I want to Live a long time and travel to the stars.”

    Who cares if that’s selfish?

I pledge to bring fusion to the discussion (primarily focus fusion) every time someone is talking about: wind, solar, geothermal, tidal, hydroelectric, nuclear, hydrogen, corn ethanol, peak oil, fracking, gas prices, electric bills, gas bills, smog, water desalinization, space travel……..

    what i good idea!
    i did this today.

    Does the stress manifest the same way as heat-stress on glass?
    this is due to relatively high coefficient of expansion on heating, versus the low overall heat conductivity.

    borosilicate glass is therefore used in laboratory glassware, since it has a much lower coefficient of expansion.

    when i look at the chemistry of this, it seems that to improve heat stress,
    stuff is added to the glass that has negative coefficient of expansion, and this relieves
    the overall expansion stresses.

    Of course if we can link forum accounts that’s in any case a bonus.
    If we enforce logging in, that might help with spam control,
    but if people feel that reverting and allowing of anonymous edits is a better approach then we can maintain it this way.

    nope.
    forcing logins doesn’t work at all.
    spammers will happily obey and create accounts, before they spam.

    instead,
    you should force image captcha solving to post any content containing links.
    that’s what works for mediawiki.
    ( note that math captcha also does not work.)

    reCaptcha may well be just the right service for this..

    Yes, he’s a little misleading on that – although it is what happens eventually, as in the Sun.

    I thought that the Sun uses the CNO cycle?

    [ edit ]
    oh, wait. ok, only 1.7% of fusion in our sun is CNO.

    yes, a neutron may be formed from a proton and an electron. usually, this happens only in the nucleus, by electron capture.

    any hints on the engineering issues to be solved? we could make suggestions, maybe
