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.

Productivity increasing mulch from bubbly gas, soil and water: combine dirt, a protein based supereffective foaming agent, gel, water and electrically derived h2o2 foam bubblemaker agent, and an ir absorptive but visible still visible dye together to
make lacey marshmallow foam soil nuggets that hold water and warm in the sun just like plant mulch. This soil based mulch is optimally 90% or higher airspace, or after a rain, waterspace. Its published online that Mulching with straw or plastic compared
with nonmulching increases yields 18-100%, producing 1/5 to double the amount of food from, at its simplest, (water, soil gathered from the gound, electrically produced H2O2 bubbles) a three chemical/component system that 1) requires no supplemental
chemicals, just owning or renting the machine is enough to make D'Mulch (dirt mulch) and fields are treated at optimally 24/7 with robot D'mulch makers. Lasers or electric arcs can ceramacize (rock melt) about 20% of each D'mulch sphere (or other shape)
to make a it-disintegrates-less patterned object, as it only has to survive rotating in a hopper and dropping to the ground, so perhaps 10-100 micrometers thick laser-glassed/ceramacized are sufficient and electricity thrifty to make. One possible
ceramic surface pattern is like a latitude and longitude line pattern.

The D'mulch with chemicals like lacey marshmallow organic chemical gels, and IR absorbing or reflecting high potency chemicals that leave the visible unaffected is likely an even better D'mulch. The cheaper D'mulch is to make, the greater likelihood it
will be used at the developing world. Unusual forms of D'mulch are possible, without chemicals lasers can fuse the surfaces of many kinds of dirt to make ceramic coated watertight dirt foam spheres, or better shapes, that float. These could be used at
rice farms to grow more rice per unit of water from the floating ceramic balls blocking evaporation. Similarly laser ceramacized foam spheres or other shapes that pack a 2D plane better than spheres could float on the surface of water distribution
channels like the ones between farms an on farms, reducing evaporation

Catalytic converter improvement: attach an ultrasonic transducer to the catalytic converter, use genetic algorithm to find optimal ultrasound frequency to create a smaller, more affordable catalytic converter from the ultrasound turbulence, travelling
waves, shock diamonds, chladni standing wave patterns at the exhaust being converted (imaginably the velocity exhaust flows through a channel could range between faster, a whole bunch more gradual, standstill, and reverse direction) (residence time in
the catalytic tubes likely determines pollution reduction amount, which can now be set with software that controls the ultrasound on the tubes. Also this could cause any carbon deposits to flake off, its possible that three or more ultrasound frequencies
would be utilized, one to create the most turbulent flow to heighten catalytic converter turbulent nonlaminar contact with exhaust and coversion of exhaust, the second ultrasound frequency causes self cleaning from motionizing catalytic converter carbon
build up, blowing away flakes, if they exist, or if catalytic converter just accumulates a "glaze" ultrasonic moving/scanning shock diamonds could make, compress and pulse the exhaust to glaze removal pressure at exhaust temperature regimes, a third
ultrasonic frequency would vibrate tall standing waves of liquid metal catalyst blend. another way to have the catalytic converter be self cleaning is to electrically heat the catalytic converter to produce higher amounts of self cleaning catalyst
chemical reactions for, imaginably, two hours once every 40 hours of driving. Catalytic converters could benefit from always presenting fresh unglazed catalytic surface so making the catalyst part of a shiny liquid metal at exhaust temperature that is
ultrasonically stirred to always present fresh liquid metal catalytic surface, and even create, ultrasonically, standing waves of higher 3D shapes like tall bumpy standing waves with much more reactive area than smooth unliquid metal catalysis surfaces
maximizes fresh unglazed surface. It is strange that i have never seen a catalytic converter wrapped in a heat retaining blanket, considering the way 2020AD vehicle catalytic converters are more effective when at higher temperatures. There are many high
temperature thermal insulators that exist, another one could be quadracore gas plenum(+) insulators like Quallofill but made of the kind of fiberglass they make pink dwelling insulation with. Thinking about how much efficiency increase comes from these
technologies, ultrasonically driven tall height standing waves could present three or more times more catalytic surface to the exhaust, allowing equivalent cleanliness at 1/3 the catalytic converter chemical expense. Electrically heating and/or
insulating the catalytic converter could cause greater warmth and more catalysis during brief duration city driving, at what was an interval that had less catalytic conversion and less clean exhaust. Imaginably, insulating and electric heating of the
catalytic converter at a vehicle that does mostly city, short trip, driving could reduce pollution 90% during 40% of the trip, reducing pollution 36%, so if a $80 alibaba catalytic converters have all these technologies it becomes about $18 per vehicle
catalytic converter at the same or better air cleanliness (city driving) the alibaba $ for the ultrasound element is 1$, the nichrome heater is $1, and the quallofill version of pink dwelling insulation is 28¢, so the catalytic converter that is more
affordable and cleans up cities' air more effectively is $20.28. That's appealing for people in the developed world as well. At $30.35 there could be the option of environmentally enthused and aligned people getting the Super Clean Exhaust option at a
new car for an additional $20.28, a startlingly profitable and high 100% markup on the $10.14 in additional alibaba parts among them an-in ceramic nichrome wire heater within the actual catalytic converter multiplenum ceramic matrix. That brings the
catalytic converter to highest efficiency temperature in 1 minutes or less from startup. That takes the person's car to 1.5 times less polluting volunrarily.

Ok, so say there's a tube with a liquid metal catalyst coating its interior. Then a center wire is made to be high voltage, and the electrical discharge looks like a test tube bottlebush, electrical dendrites sweep the sides of the tube, making
individual electrical discharge jaggies of nanometer widths, do they, when they contact the liquid metal catalyst coating raise the effective temperature of that spot they land on to thousands of degrees, noting it is just at nm sizes? Does an available
catalyst temperature of 5000°F cause completely new molecules and elements to be catalytic? If so, then if there is sufficient area at a dendritic bottle brush area to get rid of a vehicles pollution at an alibaba $ of 1 gram of gallium+ 1 gram of
silver + 1 gram of Ni or Co, then divide by three to get a new thousands °F catalyst at just 8¢ per gram of catalytic coating ($80/kg), and quite possibly a liquid metal wetted multiplenum tube would use only 24¢ of catalyst for the entire vehicle, so
manufacturing the high voltage generator to make the dendritic discharge bottle brush tube, (similar to a 20¢ ferrite am stick antenna with different windings), at a plurality of tubes electrified from one transformer could, at 100 tubes egg-crate
stamped from metal be 3-7 cents, its possible the stamped tube plenums could be made out of a high electrical conductivity metal, or heating element nichrome that really warms up under the standing acoustic wave liquid metal catalyst coating. The alibaba
$ for an array of 100 tubes is about $1.68, or $1.88 with ultrasound discharge plasma driving vibrations.
