It will be very nice to have a comprehensive list of possible so called "disruptive inventions" or "closing inventions" i.e. such inventions that destroys industries and can do a lot of harm to corporations or states.
as kickstart, order means nothing:
- antigravity
- neutrino beam communications
- force shield
- electricity accumulator with decent power density (orders of magnitude larger than current lithium crap) and reliability
- FTL travel
- high-efficiency fuel powered electricity generator without moving parts
- atomic level 3D printer/copier
- inertial mass control
- simple consumer-grade fuel converter (organic compounds to gas/diesel)
- plants growth speed accelerator
- useable way of making building materials (blocks/bricks) from any soil. ....
Please continue.
E-Cigarettes.
Big corporations can't monopolize it because it's cheap and accessible to make the liquid and the parts (which are also repairable).
As a result, the state has been killing off small businesses with new regulations every few years. The website I've been using for the past year will be shutting down their site soon and will only now begin to take orders over the phone. If not for the fact that they'll take orders over the phone, this would've been the fifth time I'd have to go looking for a new place to buy eliquid due to my go-to shop being forced to shut down.
There's been no known health issues after 20 years despite many e-cig users vaping far more than they smoked, but there has been massive propaganda campaigns to scare people into not using them.
