L
LEONARDO DA VINCI SYNDROME:
Creative people often get more ideas and visions faster than they can
implement them, making them unable to complete a project before rushing
off to the next (like Leonardo da Vinci).
LINDE SCENARIO: A scenario for indefinite
survival of intelligent life. It assumes it is possible to either create
basement universes connected
to the original universe with a wormhole
or the existence of other cosmological domains. Intelligent life continually
migrates to the new domains as the old grow too entropic to sustain
life. [Mitch Porter, 1997. The name refers to Linde's chaotic inflation
cosmology, where new universes are continually spawned.] See The
Linde scenario, v0.01
LIQUIDENTITY: See fluidentity.
LOFSTROM LOOP: An beanstalk-like
megaconstruction based on a stream of magnetically accelerated bars
linked together. The stream is sent into space, where a station rides
it using magnetic hooks, redirects it horizontally to another station,
which sends it downwards to a receiving station on the ground. From
this station the stream is then sent back to the launch station (a purely
vertical version is called a space fountain).
This structure would contain a large amount of kinetic energy but could
be built gradually and would only require enough energy to compensate
for losses when finished. Elevators could be run along the streams,
and geostationary installations could be placed along the horizontal
top. [Named after Keith Lofstrom, who did the first detailed calculations
on it in: Lofstrom, Keith H., "The launch loop -- a low cost Earth-to-high
orbit launch system," AIAA Paper 85-1368, 1985 ].
LONGEVIST: A person who seeks to extend
their life beyond current norms (but who may not wish to live forever)
[Max More, Extropy #10].
