      From: treon3verdery@gmail.com              I read that lasers can polish lens glass to 10 micrometer bump size, but 5 um       or 1um is optically transparent, its likely already well researched but a 111       times faster pulsed laser making a chirp could be able to reach high energy       glass modification        temps while lasting much briefer intervals so a swirly surface scan has more       voxels on the surface to laser away undulations on the surface, wavelets,       grinding with lasertweezers and scrap microparticles, use wavelets to leave       last pass islands that can        be made into polishing grit, or just leave a bunch of meridians to turn to       polishing grit on a spherical lens, sort of like zapping off the lines on the       at&t sphere to stays put micrometer dust then vigorously wiggling that       micrometer dust with laser        tweezers to physically polish the surface to optical transparency. As another       technology at 3d printing eentsy laser comminutable polishing grit or dust       could be printed on outer surface layer, then the new part of the 3D printer,       the laser tweezing/       laser tractor beam just swirls the polishing particles to give the upper       surface and possibly sides a super smooth polish (swirling polishing particles       with a laser kind of reminds me of a rotating with light radiometer, they work       without a fluid, i        first read about laser tractor beams working in a fluid/liquid)               Aquarium peltier nooks for fish to enjoy and possibly live longer from, think       of a bunch of little, medium, and large round windows on a beautiful rounded       piece of architecture in a fishtank, each windows sides have an annular       cooling or warming peltier        element that cools or warms the water just at that windows depth and volume,       fish that liked cooler water could hang out in those window volumes and fish       that liked warmer water could visit those windows, perhaps the aquarium       decoration could have angled        mirrors so you could see its entire decorative body when looking at the       aquarium, fish that sought out the cooler nooks might live longer as zebrafish       live over 70% longer in cooler water, note, this is just an aquarium decoration              Clean photovoltaics transparent containers with clip on "itty bitty book       light" laser tweezer/laser tractor beam that vigorously agitates dust       particles during any rainfall or between rainfalls, the clip on photovoltaic       cleaner, rather than an itty        bitty book light could be a long tube. Rather than expensive dynamic aiming,       either a $. 1-1.00 multimirror microprojecter optic ic could make and steer       the 2D laser tweezer pattern to sweep away the dirt. Multimirror array       scanning or casting laser        tweezers or laser tractor beam is also a possible good photovoltaic and camera       surface cleaner for cars like self driving cars where keeping the       camera/video/lidar clean is beneficial, and robots, including social companion       robots, and planetary explorer        vehicles and robots              Peltier effect electrocooling dew making annulus around a lens causes a film       of water to gather each morning and flow across a lens, keeping it clean              Cheap and easy 10-24% lifetime photovoltaic panel power gain, Also, the       cheapest 120 watt wet/dry handheld vacuum at alibaba is $1.80-2.00, simply       placing the same assembly as an air impeller to blow dust off a multimeter       area of photovoltaic (panel        container) the vacuum is described at alibaba as being competent with water,       and of course rather than one oval section sucking tube, the air impelling       version would have a long apertured flute holish tube at the higher part of       the photovoltaic panel to        blow particulates off,another thing photovoltaic panels could do to stay clean       is to vibrate resonantly during rain events, this assists the rain or also the       motionized air to reduce dirt and particle accumulation, physics resonance       causes motion to        accumulate in a system so a small gradual motion accumulates to large motions       as energy accumulates with time, a piezoelectric vibrator is 10¢-1$, and a       sexual pleasure weighted thunking to vibrate motor is about 35¢, putting       resonant vibrations during        the rain could be very cheap and heighten power output                      [continued in next message]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
