    Another wood that might be laser peened to make a stronger product is building materials, noting that it was very doable to find published papers that mention 1cm laser spots reaching 1 cm of depth, peening both sides of plywood and its surface could
    take less than 1 second and be a continuous rather than batch process, laser peening at plywood then might strengthen the 2cm full thickness at the entire sheet, also it may be possible to reengineer plywood glue to be highly responsive to laser peening,
    perhaps getting 60% greater strength from the glue and the 30% composite number for the wood;

    applying a laser peening mask, that is laser receiving, highly uniform shockwave making coating is optional, but if one is used a thin water washed coating or dusting of the ceramic that has the highest strength gain (thus far alumina)or cheapest highly
    effective material as far as i know, quartz sand turned to powder

    One advantage to testing laser peening on polymers is that synthetic fiber carpets and floor laminates could last 30-60% longer, remaining soft and new looking longer; there is even a chance cotton becomes stronger

    Laser peened metal roofs are likely to better resist corrosion, they would be peened before painting at the factory, similarly polymer plastic covered roofs could have the silicone or other polymer sheet rolls laser peened at the factory

    Circle inside circle laser peening with picosecond or smaller delay that nodal addition creates a supersized or superstrong laser peening shockwave

    A flash drive that provides its own electricity to keep data fresh as well as uses ambient rf and photovoltaic power to provide refreshment energy, optimally the data lasts hundreds or thousands of years
    Deep wide flash unit ic feature hosts 100 times the current of a regular 2 terabit flash unit, noting the internet says a flash memory stores a decade without a voltage refresher, connecting the 100 times amount of electrons large flash unit at a 1:1
    ratio via a resistor to an actual data storage data flash unit causes trickle charge maintenace of the switched on flash bit or byte, conceivably if a decade reduces regular flash memory to 1/4 stored electrons the trickle charge is at 24-26 times a
    regular flash memory, sufficient to , at an actual very long lasting flash drive there is the technology of having an antenna similar to a rfid tag that picks up ambient RF, uses it to charge a <1 gram battery and then uses the accumulated electricity to
    periodically rewrite the data to the flash drive, the data refresh power available at areas in the country 40 miles from the nearest town is the amount of electricity available, also the antenna could absorb the kind of EM that is high frequency such
    that it can pass through a faraday container, genetic algorithms have improved the effectiveness of antennas 3.5 times so the high frequency electricity gathering antenna could have genetic algorithm seeds made by engineers, also a published paper says
    that sheathing an antenna with a ferrite layer causes 30-70% greater antenna effectiveness, another source of data refreshment voltage is a surface photovoltaic on the flash drive, notably even small amounts of ambient RF or photovoltaic electricity
    produce the ability to refresh the amount of electrons at the flash memory every 900 days as an alibaba parts $ amount the rfid tag antenna is about1/10 of a ¢, the battery is .5¢ button battery with decade charge chemistry, the microcontroller that
    scans and refreshes the flash drive can be made a part of the existing usb interfacing electronics ic for 1/10th of a cent, that makes a highly likely to retain data flash drive for 7/10ths of 1 cent, a photovoltaic can complement the ferrite sheathed
    antenna version for 3 cents to make 22 milliwatt photovoltaic version, a further improvement is to utilize the continuing growth in memory capacity to store just 2 terabits of data in 8 Tb of flash memory with multiple copies of the 2 Tb core data each
    on a different 900 day refresh schedule, with the possibility of increasing it 2¢ a second USB physical metal socket can be added to the flash drive doubling wobbly socket tolerance, also, for .5¢ the flash drive can have 4 stay-clean metal stripes on
    it, if the two metal USB connectors both get wobble then the conductive stripes can be connected to a usb using computer or reader
