    A molecular assembler as defined by K. Eric Drexler is a "proposed
    device able to guide chemical reactions by positioning reactive
    molecules with atomic precision."
    Drexler also introduced several related terms, such as "molecular
    manufacturing," which he defined as the "construction of objects to
    complex, atomic specifications using sequences of chemical reactions
    directed by nonbiological molecular machinery", and "molecular
    nanotechnology" that comprises molecular manufacturing together with
    its techniques, its products, and their design and analysis.

    Could it be possible that in the not-so-distant future we could be
    able to manufacture our own gadgetry at home?
    It certainly sounds more like fiction than science, and the idea has
    both its advocates and detractors.

    This video explains the process of molecular manufacturing and further
    assembling.
    Whether or not it's a viable process remains to be discovered, but the
    project does make some sense.

    A nuclear assembler as defined by DNA. Gemome is a "proposed device
    able to guide nuclear reactions by positioning reactive nucleons with
    sub nuclear precision." Genome also introduced several related terms,
    such as "nuclear manufacturing," which he defined as the "construction
    of objects to complex, sub nuclear specifications using sequences of
    nucleonic reactions
    directed by nonnuclear sub nucleon machinery", and "nucleon sub-yocto-
    technology" that comprises nucleonic manufacturing together with its
    techniques, its products, and their design and analysis.

    Could it be possible that in the not-so-distant future we could be
    able to manufacture our own nuclei at home? It certainly sounds more
    like fiction than science, and the idea has both its nutters and anti-
    nutters

    While we are about it, I want a home assembly kit for dark matter. If
    I could get hold of enough dark matter, I could build my own dark
    black holes, and transmute normal light matter into energy with 100%
    efficiency by dropping it into one of my dark black holes (which would
    - of course - radiate like fury while this was going on).

    Oddly enough, I've not seen this proposed in any science fiction that
    I've read. Maybe I should have filed a patent application, though you
    can't really do that until the emnabling technologies are up and
    running.

    That's not true. You can file a patent application
    on anything. It might not be awarded if the examiner
    finds your application insufficient in some way, but
    you can file.
     
  5. Speaking of nano-technology, I've got a relevant question.

    AFAIK, nanobots will use molecular conformation changes (e.g., Drexler's
    "mechanical" computation) or electronic energy-level transitions to
    process internal information.

    Drexler info:
    http://www.e-drexler.com/d/06/00/EOC/EOC_Table_of_Contents.html

    Which has more advantages, mechanical computation or computation using
    electronic energy-level transitions?

    That reminds me, I need to patent cheese tomorrow.

    Since you can't actually do anything useful with either approach, this
    involves distinguishing zero from zero, which happens to be a waste of
    time.

    If you want to read science fiction, read Neal Stephenson - at least
    he can write entertaining nonsense.

    Something of a waste of money. Someone patented a scheme for
    defending the Philipine Islands with torpedo-carrying aircraft, and
    sued for royalties when the U.S. Navy finally put it into practice.
    They lost teh case because the scheme couldn't have been reduced to
    practice at the time the patent was submitted.

    Damn, that's not cool, we want proper rights for Unobtanium. >:) A formal
    slot reserved in the Periodic Table would be a start.
     
  10. Guest

    The periodic table just covers regular matter, where the nuclei are
    built up out of protons and neutrons, and you put on a frosting of
    electrons to neutralise the protons.

    Unobtainium, dark matter and dark energy are going to have their own
    aperiodic table, built up out of really exotic stuff like psychopathic
    quarks and slow axions.

    I'd best fire up the interstitial gravity drive then and dip into the Eye
    Of Harmony for a bit of the wherewithal to make the legs and a few chairs.
    I'll leave the table top to those who know what they're doing. :)

    Heck, you can do it today - just go down to the corner store and pick
    up a Scanning Tunneling Microscope:

    ;-)

    Have Fun!

  13. Well, with neutronium femtomanipulators[1], we could actually pick the
    protons out of four hydrogen atoms, physically slap them together
    until they fuse and absorb two of the electrons, and use a nano-MHD
    generator to extract the kinetic energy from the resulting alpha
    particle. ;-)

    Or maybe let it recapture the electrons and use the helium for rocket
    exhaust. From what I've heard, fusing four hydrogens into one helium
    releases a LOT of energy. ;-)

    Cheers!

    1. That's six orders of magnitude smaller than nanomanipulators,
    which probably still isn't small enough - zeptomanipulators? ???:-/

    Maybe attomanipulators, and we could call the product the "Atto-Boy". %-P
     
  14. Guest

    That's a crude way of doing it - it works for God, but she's got to
    build a small star to get it to work

    http://en.wikipedia.org/wiki/Proton-proton_chain

    thugh the nuclear fusion industry thinks you can get away with brewing
    up deuterium in magnetic bottles.

    If you've got a decent zeptomanipulator, and a carbon nucleus or two
    you could use the Bethe cycle, as used by heavier stars

    http://en.wikipedia.org/wiki/Proton-proton_chain

    Dropping protons into black holes does convert a lot more of their
    mass into energy.

    The STM only works for two-dimensional structures, and they tend to
    break up if you try and peel them off the surface on which you built
    them.

    It is going to take X-ray laser forceps to do the job Drexler has in
    mind.

    Please, explain what that device has to do with a "proposed device
    able to guide chemical reactions by positioning reactive molecules
    with atomic precision." to this hopeless ignorant soul.

    Thank you.

    Nobody here takes Drexler very seriously, and this thread has been
    happily satirising his proposition. If we ever do get into that kind
    of nanotechnology, it will probably be via genetic engineering, which
    has the advantage of being practicable.

    I understand that Nanotechnology could probably be used to implement
    changes in genes ...
    but using gene sequencing to construct non-biological molecular
    machinery is something I fail to grasp.

    Alan Adrian Guest

    You change genes to adapt existing protine builders so that they construct
    elements simular to the way natural life does it... only you design so that
    you get the desired nano products out. (within the constraints of protine
    structure) Such products can be designed to self assemble when mixed to make
    bigger structures... etc...
