Lifesavers looking ultrasonic piezo transducer
Reflector on farthest from water side,
Vacuum cleaners, but especially steam cleaners could have piezoelectric transducers on their rolling bars to blast material off the carpet, this works better at moist surface contact like steamcleaned carpet, the piezoelectric operates above the range of
hearing of people and companion animals
A glove with an ultrasonic element above human hearing range might be able to open tight jars, or not

Powerbank put two or even 3 usb plugs from different manufacturers at any powerbank over 5000 amps, make one of the usb board ports 360 rotateable like an rj45 product i saw, diamond peen case cheaply to increase scuff resistant

Thingy: on indicator LEDs could have a pattern like a bicycle reflector QR code leds etched on them so that they would light cast model number, manufacturer and website to a surface 3-14 inches away when a phone image was made, this would look like
glowing bike reflector glitteriness to a person looking at the indicator light

Baby diapers and adult diapers could be improved with laser texturing or warm embossing to have microtroughs and sensationless or velvelt like water shedding micropillars all over the inner surface except next to hydrating pad areas where the pores are
lined with insulating hydrophilic troughs

Toilet tissue could have the felted thin flat layer be soaked in a shorter fiber solution that was gelatinized momentarily with acid and embossed with hydrophilic troughs and hydrophobic pillars on opposite sides so water was repelled from reaching the
back from the middle, a two ply highly absorbent top with pillars in the middle and back surface pointing inward that keep the back of the toilet paper or facial tissue dry, this could be as affordable as generic toilet paper as it is just 2 ply with
pressed gelatinous woodpulp stage microcolumns and microtroughs, an enhanced fluid soak up without soak-through makes it possible to use less paper pulp at an equivalent to thicker toilet paper performance, making the tp more affordable and ecologically
beneficial

There are many ways to cheaply effect absorbency and strength of toilet paper, paper towels and other wiping paper products, one approach is to put particles of white bismuth hydroxide in the paper pulp and then exposing the wet paper being formed to a
high intensity magnetic fields that oscillate, moving the highly diamagnetic bismuth hydroxide around, making paper fiber lumens, and at egg crate standing waves, doubled (or higher) surface area, enhancing moisture absorption or at the back of toilet
tissue, greater density and smoothness, laser peening could have smoothness and reduced water soak through at the back of toilet paper, increasing effects on paper, and be very cheaply applied during paper manufacture, ultrasonics are another way to
produce useful paper microgeometries, with standing waves powerful enough to make high egg crate morphology wet paper forms with airfoam whitecaps, the high egg crate undulations at the paper scrape poo, or dirt off, and the super airy whitecaps are felt
as extra soft

At paper towels they must have already thought of including .5% 2000 times puff up with water acrylate powder at the paper towel, turning the paper towel rapidly to a 1-4 mm thicker making a water nondrippy (?) used paper towel, hydrophilic gel diapers
are 2¢ each at alibaba and likely contain enough gel powder to make 2 rolls of paper towels at an added 1¢ per roll but an order of magnitude more water pickup,

If laser peening strengthens polymers 30-60% then currencies of all nations can circulate 30-60% longer

If laser peening strengthens paper then paper grocery bags might be makeable with double digit % less material, also a net mesh could be raised like a watermark at the bag, or printed on out of a strong biodegradeable material like polylactic acid
polymer or a vegetable oil derived polymer to strengthen the bag so, at the same size bag the kraft paper could be 1/3-1/2 thinner, reducing wood pulp use, making a mesh on the bag could be as simple as printing the biopolymer reinforcement pattern onto
the bag paper and, optionally ultrasonic or large area simultaneously holographically welding the printed mesh to the bag, varied patterns of bag reinforcement are possible from homogenous mesh to a cheaper custom mesh like denser mesh at base and
corners, the printed on mesh goes onto the bag paper interior so the outside is aesthetically smooth, similarly a biopolymer custom strenthening mesh on paperboard like cereal boxes and cookie boxes could allow thinner paper, saving imaginably half the
paper pulp

Opaque white Polymer containers like yogurt cups, LDPE beverage, milk, and detergent containers, trays, could all do this thing of having materials saving reinforcement ribs or mesh at the interior of the container where it is rarely seen, at products
where the interior mesh can be seen, aesthetically pleasing ribs or meshes can be made

Landfill beneficial composting bacteria spores could be placed at 1/300th of a cent amounts as a coating on one of the layers of a juicebox, at $3/gram that is 100 micrograms of composting bacterial and fungi spores, a bacterium weighs a picogram, so if
a spore is a tenth that then there are 333k bacteria produced from a juicebox, one billion colony forming units at $3/gram is at a tenth of a picogram near 1/30 of 1 cent, the environmental benefit is that the landfill composts faster; juice boxes are 1¢
each at alibaba; some consumers may more highly value products whose packaging degrades at the landfill
