Who is Archimerged and why is he submerged? Ark is just another geek who wants to carry on public discussions of his brainstorms, disclaiming credit (credit? who are we kidding?) or blame while remaining relatively anonymous. He also makes minor corrections on Wikipedia, reads Groklaw obsessively, always installs the debuginfo packages so bug reports are useful, sometimes provides patches, and gets these brainstorms…. Maybe someday one will pan out.

Ark has been a boy-genius hacker ever since 1966 (IBM 1620, 7090, Univac 1108, G/A 1830, Modcomp II/IV, Z80 CP/M, embedded 68020, Vax 11/780, Mac II, Sparc 10 Solaris 2.2 to 7, i386 Linux RedHat5 to Fedora7). He has an e-mail somewhere from RMS thanking him for fixing a bug in emacs in the mid 90’s.

He used to use Mathematica (starting in 1990 on the strength of Nature editor John Maddox’s review) but now his old copy stopped working due to glibc incompatibilities and he can’t afford the upgrade fees and opposes it also because it is non-free.  He is learning Maxima now, and notices how many features of Maxima seem much improved in Mathematica.  Lots of stuff in there (like the global names and the semantics) is probably not subject to copyright, and a free interpreter ought to be built using clean-room techniques, with testing against freely available Mathematica programs written by third parties.

Ark is not trying to raise money for his brainstorms and thinks patents should be abolished. All text is licensed under the Gnu Free Documentation License and the Creative Commons Attribution 1.5 License (take your pick).

It is probably fairly easy to blow Archimerged’s cover. If you succeed, please do not make it trivial to google his name and mailing address and find this blog, unless you are ready to pay him a postdoc salary for the next ten years of part-time blogging.

The submerged part comes from a particular idea about how to build a heat engine air compressor from a slightly modified Archimedes Screw which is submerged under water. Instead of raising water through the air, this screw pulls air downward through the water. See the Renewable Energy Design Wikia article on this design. (Archimerged is founder of the Renewable Energy Design Wikia but hasn’t done much with it lately and no one else ever got excited about it).

    Hi, i’ve seen your trombe liquid engine picture on HotAitEngine’s files, and some of your comments here regarding achieving small buble sizes.

    Here-s a tip: Use CO2 instead of air. Buble gas. It should disolve easy into the
    cold water (where you want it “small”) and be as easily released into the hot water – where you need it as bubles.

    One cubic meter of water at standard pressure/temperature dissolves as much as 0.732 cubic meters of gaseous CO2. Much more when its colder, much less when its hot.
    Pressurising the pipes should increase this ratio.

    That means you dont need the middle bump to collect the air and reinject it into raising hot column of water. It is just dissolved into water until it heats and the head lowers.

    The main problem I see with this engine is no matter how efficient the heat recovery is, the water carries 2-3 thousand times more heat than a gas with the same volume. So I assume the heat lost by water exchange between cold/hot sides is significantly bigger than the heat converted by gas into work.
