      From: treon3verdery@gmail.com              A simple modification to liposuction nozzles and tips could cause less harm       while improving aesthetic appearance and even heightening wellness.       Ultrasonically stimulated knives glide through materials with minimal force,       so a liposuction nozzle or        abortion tool could glide through tissue, cutting and sucking it out with less       blunt force, at liposuction being able to move through tissue with less force       means that smaller contours can be produced with less effort more precisely,       so a planned        topology map of how much fat to suck out where can have smaller features and       ultrasound co-imaging can guide the procedure, i read that sucking away the       abdominal fat on obese rodents makes them live longer so this could benefit       human longevity as well        as be a cosmetic surgery procedure, also, when you think of sticking a vacuum       tube in adipose tissue and sucking it up at 14.7 psi vacuum, if the fat is       liquified and homogenized at, or just before, the probe tip, the procedure is       faster, and the        liposuction probe can be smaller and narrower for better aesthetics, that       suggests putting another ultrasound tissue liqueifier or laser element at the       tip of the probe to liquefy and homogenize the fat so it is a liquid goop for       the suction tube. It is        even possible that a vacuum suction tube with piezoelectric vibrating above       human hearing would cause the liquiefied fat goop to travel easily without       clogging, even at very aesthetically precise narrow tubes used for sculpting       small features              A regular refrigerator that saves some perhaps single digit % of energy is a       household refrigerator with 2 dutch doors, and a seperate door for the       freezer, at a one door fridge, my perception is that a lot of cool air slides       out the bottom, and the air        in the fridge gets mixed with room air from the fan effect of the door,       splitting the refrigerator doors keeps the coolest air from spilling out the       botton and if the top dutch door that accesses the most frequently used top       shelf is half the size then        there is only half as much warm air mixing, another slight advantage is that       since people usually get top shelf items 60-80% of the fridge openings are top       door, which saves the energy from what would have been an all one door cool       air slide out.              I think i may have previously made a note but beyond human hearing       piezoelectric transducer microwiggling of radiator fins at air conditioners,       building heat pumps, back of fridge cooling coils, PC CPU heatsinks, baseboard       heaters with fins, automotive        radiators and commercial refrigerated storage coolers could increase air       mixing and be energy and $ efficient, also like the way sand moves is       macroscopic at vibrating chladni plates, bigger shapes and movements of       cooling air are possible on the fins if        different ultrasonic tones are sequentially made by the out of human hearing       range sonic transducer, moving the air and refreshing it, this could be a       simple circuit like an audio toy music chip (1-10ยข) that tells the amplifier       that feeds the        piezotransducer what sequence of frequency to make, which is a little cheaper       than a microcontroller              Ceiling fans are published as an effective way to increase comfort while       saving energy, adaptive surfaces at airplane wings that slightly change their       contours to be more efficient, ceiling fans with adaptive surfaces could       cool/blend air for greater        comfort even more efficiently, an ultra cheap alternative to a smart polymer       surface is to vibrate the fan outside the range of human hearing at less than       19Hz with a cheap piezoelectric element, cheaper than that is just having an       eccentric path pringle        shape making wobble drive, like the nonrotational motors of those photovoltaic       dancing character solar toys that has a magnetic winding that does a figure 8,       Pringle, or lissajous rotation, the microwobbling could be measured as causing       more air mixing,        i don't know if microturbulent flow at the fan surface is effective, but if it       is, a piezo sonic transducer at the fan at above human hearing frequencies       could make it vibrate, there is even the possibility of making traveling waves       of blade flexing if        the fan and ultrasound emitter are physics resonantly tuned              There are many technologies being researched to transform water into useful       hydrogen and oxygen gas, i have read about hydration shells where in liquid       water spheroid tesselated layers of h2o surround an ion or maybe a particle,       some additives can reduce        the number of hydration shells while others might increase it, changing the       number of hydration shells might increase the energy efficiency of splitting       water, so there could be an ion additive that does that, another approach is       that for systems that        use electrodes the nanosurface ball bearing look of the electrode might on its       own effect the number of hydroshells, if it does, and customizing it makes the       process more energy efficient then any of laser etching, chemical etching,       laser peening or        direct contact molding could make the better surface, direct contact molding       is interesting because silicone polymers can actually get a direct impression       from DNA, that is molecule sized nanotexturing, since the electrode is likely       conductive a very        soft near liquid metal electrode like a gallium alloy could pick up embossing       of a hydration shell optimizing pattern from some embossing element                     [continued in next message]              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
