Making electrical distribution networks more affordable benefits electric cars.
Screen a library of billions or trillions of metal alloys to find those as conductive or more conductive than aluminum, a 9600 DPI inkjet printer can print 2.19 million different metal oxides or chlorides onto a 300 mm IC wafer, the wafer is then warmed, or lasered, to reduce the oxides or chlorides to metal alloys that are contacting conductors on the IC wafer, a 4 GHz computer can measure the resistances of all the alloys in less than 1 second, 4560 wafers screens one billion alloys, if a 19,200 DPI inkjet printer is possible then each wafer screens 4.3 million alloys, it is possible that rather than an inkjet printer 100 passes with a gradient spray nozzle that deposits 1 million discernable amounts at a 30cm (300mm) area (or a sprayer that sprays 100k discernable amounts at a 3 cm area, with the fluid used on each sequential separate 3 cm area having 1/10 to full strength dilution) is 100 billion different alloy compositions per wafer,
Repeat the process making alloys that branch at their composition from the highest conductivity alloys at the first wafer
Aluminum alloys could also be screened with 1/10 to 90% of some other element more affordable than aluminum, manganese, silicon, sodium, potassium, iron are possibilities
1/10-90% iron alloys as conductive as aluminum would make building and maintaining electric networks, including long distance power lines and dwelling wiring much more affordable
Greater electrical network affordability brings greater electrification to the developing world and provides infrastructure so they can use electric cars

A person who knows could explore the financing of electric cars, Electric cars could benefit from their being the option of applying the recycle value of the batteries to the financing up front, reducing monthly payments, note though that if the bank gets the battery value, then at battery replacement experiences the battery's full $ amount is without utilizing the previous battery's value is utilized, at some spans of having a car this might make sense, at others not so much, if you like lower up front expense, or also lower monthly expenses, and do not mind lower (old battery) car value when vending it to another person then this gets more people acquiring electric cars more rapidly, if you think you will keep your electric car a long time then you can be an optimist that the new battery, years later, will have greater power density and affordability and omitting giving the bank the battery could make sense, you could also get a more affordable battery (China) as well

If 30-60% of an electric cars manufacturing $ is not at the battery, then cars that look really nice and have lots of room and features could be based around what I perceive is the similar affordability of different carapaces and interiors, the roominess $ is perhaps near 10% variance between cars. Possibly car places, or regional assembly locations, or garages could put any of a variety of standardized carapaces and interiors on an optimized electric car base, the wheel motors at the base are specified to produce up to 1/10 more torque than necessary at a typical car so a bigger carapace mass still permits acceleration and handling like other the cars

Longevity technology
I saw a thing where they thought they found the part of the rapamycin molecule that caused the longevizing mTOR effect, finding the fewest atom mTOR decreaser, then halogenating that and screening a library of variants at yeast to find the highest increase in longevity benefits from reducing the combinatorial space at the fewer atom mTOR drug

Fluorinated proteins, do they work, I read that fluorinated peptides are 1.5 times as active, would making fluorinated proteins also work, screening a library is one approach, as are chemical protein sequencers with an extra 23 containers of fluorinated amino acids that can swap a fluorinated amino acid with a regular amino acid at anything they build, 100 fluoroamino acids, or silicoamino acids would give the engineer four different fluorination locations to utilize, this could make protein drugs 1.5-a greater amount more effective, software could suggest where to put a teflonized amino acid compared with a high electronegativity fluorine amino acid to make a protein act like it does only moreso

Things that fill children with happiness
Travelling in a driverless car could be fun, besides the computer, tablet, and other people in the car the driverless car could take scenic routes especially appealing to children, and suggest stopoffs at parks, museums, and places of amusement, also, educational software could be available, from 30 minutes to one hour of car usage per day this makes, of 16 hours spent awake per day, things 3-6% more fun each day, or from 3 to 16, 2372 to 4744 hours more fun

I think cars with fold flat front seats that let's people have sex on them are beneficial
