   Treon Verdery to All   
   Plastics exposed to light (1/3)   
   14 Aug 22 01:45:26   
   
   From: treon3verdery@gmail.com   
      
   like outdoor light preservative: include light frequency downcoverting   
   nanocrystals or quantum dots that downconvert all UV to IR, this makes   
   plastics and paints resistant to uv light including outdoor sun exposure, also   
   environmentally beneficial    
   technologies that velocitize polymer disintegration include photonic frequency   
   upregulating nanocrystals and quantum dots to make waste plastics an order of   
   magnitude more disintegrating from sun or artificial light.   
      
   Very thin cold plasma ptfe nano or micrometer sputter coating causes   
   resistance to chemical attack and reactive oxygen diffusion, and with surface   
   patterning from a secondary femtosecond laser can be extremely hydrophobic.   
   This preserves anything exposed    
   to moisture like garden hoses and light pipe photon collectors for   
   concentrator photovoltaics, as well as roofing polymers and polymer siding at   
   dwellings and other buildings. There are also applications like exterior   
   building paint, infrastructure paint,   
    and vehicle paint. Drones with enough electrical power could sputter coat   
   ptfe onto the surface of any new or previous construction, then use broad area   
   light casting gratings or holograms to make the ptfe microcoat have grooves or   
   other features so    
   they are even more shedding of water and hydrophilic. This makes things last   
   longer. Nanometer thick sputtered teflon coatings are much cheaper than making   
   things out of teflon/ptfe. Anti-rust nanocoatings and could also be   
   made/coated this way, as could    
   outdoor furniture, and even interior and foundation construction lumber and   
   drywall. Another use could be preserving historic buildings. Also PTFE is just   
   one material it could be that laser or magnetron sputtering of amorphous   
   fullerene glass, 1000    
   times harder than diamond could, at all these applications, including   
   buildings and paint, and building materials, provides superior resistance to   
   being scratched off and thus lasts longer on structures and objects exposed to   
   wind and rain.   
      
   As a different technology, It seems possible, but is unknown to me if a   
   sputtered polymer coating and the autowetting super hydrophilic laser etch   
   pattern if applied to concrete/cement surfaces causes greater cement surface   
   hydration and simultaneously    
   higher strength and resistance to forming potholes, as well as greater   
   resistance to cracking in the upper 1-8 mm of cement, such as at urban and   
   country roads. This would discourage potholes, and discorage spot treated   
   potholes from growing.   
      
   The possibility of much smaller asphalt filler mineral chunks would make   
   asphalt less porous, so much so that drone treated polymer sputtering and   
   superhydrophobic laser etching keeps water out of the pothole filler, which   
   could be raised .5 mm above    
   surrounding road surface. (With robotic precision) This precludes wet grinding   
   of the pothole from vehicle tires.    
      
   Another way a robot drone could get rid of potholes is to have a supply of   
   expandable bags, similar to balloons that it can fill with optimized geometry   
   polymer volume filling shapes, high adhesion nanocement and water. A spike or   
   drill on the robot does    
   two things, it places an anchor screw for the pothole filling bag to attach   
   to, and it provides an empty space water drain. The anchored solidified bag   
   takes up 90-98% of the pothole, and the rest of the pothole is filled with   
   ultrasonic compaction of    
   the perimeter of the fill bag aligns the polymer shapes in the fill   
   goop/rubber/neoasphalt so they avoid migrating, even under turning car wheels   
   that torque potholes that have been filled. Optionally a stainless steel top   
   disk on top of the bag gives    
   the uppermost surface of the pothole a laser level precision of flatness of   
   repair. computer simulations to make sure the anchored bag, perimeter fill an   
   optional top plate doesn't shake apart with cars that travel 1-300MPH. At the   
   3-7% not filled by the    
   bag on value effective goops like low density polyethelene microbeads in a   
   "tar" or rubber matrix with barium sulfate so the pothole repairs are white.   
      
   Self driving cars that travel 300MPH during commuting reduce commute times to   
   1/10-1/5 of a 1990's AD time to commute in the 20 largest US cities, or at   
   trucks, transporting goods about 6 times faster at 300MPH with self driving   
   technology. i think self    
   driving vehicle technology when it is equivalent in safety to 4 times the lack   
   of vehicular accidents of the upper safest 2% of human drivers is adequate,   
   and of course even less accidents than that is even more beneficial. The   
   technology to make 300 MPH    
   electric cars, i think, exists, and 300 MPH hydrocarbon powered vehicles   
   already exist.    
      
   Bulk laser holographic treatment of plant sourced agricultural Mulch at the   
   farm, or agribusiness could make it much more hydrophilic or hydrophobic,   
   beneficially effecting water retention and supporting anti-plant-disease   
   microbiological communities. As    
   a technology this is as simple as 11 watts of $1/watt alibaba laser power   
   shone through a hologram directed at the interior of a plant mulch tumbling   
   drug, if the laser etch lines reach 90% of the tumbled mulch, then that's   
   likely enough to make a good    
   soil hydrophilicity profile.
