Not taking that bet. From the linked wikipedia page.

According to reporting in Wired and Slate, the United States Patent and Trademark Office has at times considered applying secrecy orders to inventions deemed disruptive to established industries.

You may be sure that there are times when they did more than consider it.

It looks like they fuck over inventors.

Most of these appear to be for government projects such as with the Department of Defense and the NSA.

Sometimes, a regular invention outside of government contacts gets labeled with this and the government don’t pay for it. The inventor isn’t allowed to talk about it so they get fucked out of any income.

They'll suppress it unless they can make money off it like crypto or "AI".

This is the plot of The Saint and now I have to watch it again.

I suspect the “threatens economic stability” is stuff like printers that can produce dollars and the type of paper/thread/plastic material that makes up modern currency. I think people are looking for a conspiracy here when it’s just a logical choice. Some things people shouldn’t have a playbook on how to create.

that's cool. Seems a bit 'busy' for something that should be foldable

Pills that actually make your wang the size of an elephant trunk while making it prehensile.

Reticulated splines

I wouldn't be surprised if most of them have to do with rocketry or bioweapons and other things to make them work. I've designed things personally that are not destructive themselves but aid in testing or improving accuracy of hypersonic vehicles. The DOW (formerly DOD) did not allow us to apply for patents due to national security.

Successfully dividing by zero.

My flying boots, for one.

Probably a really, really good engine that doesn't need gasoline.

Often it will be a specific new process for making, say an unusual alloy or critical component.

Also in 2016, there were 5,680 patents according to this site. Yikes. That’s a big increase.

Invention Secrecy Increased In 2016

Cars that run on old oil are basically just diesel engines. It's also pretty easy to get a vehicle with high fuel efficiency, it's really hard to get one that also meets emission standards and doesn't kill you in a crash.

A lot of those claims are just direct horse shit in the "infinite energy" category, or "this car runs on water"

Lol, early 2000s diesels can get 60+mph

They do have networks of radiation sensors and reporters because of the guy who built an atomic device out of smoke detectors, giving himself and others radiation poisoning. Also, there have been some nuclear weapons go a tiny bit permanently missing, and suitcase-size dirty bombs were a huge scare for a hot minute, etc etc.

Honestly it's really shocking we escaped the past century alive.

Look, we need to open source genetic engineering.

Some bastard will create super-ebola, sure, but some proactive individuals will quickly create a free vaccine for it, and for cancer and the common cold. (It will also turn you into a literal furry, of course, but that's probably a price worth paying.)

Yes this video destroyed me and made me realize that any life-changing awesome invention would surely be suppressed

Real answers, probably just 6,000 different targeting solutions and the rest is weird sex shit that oligarchs want for themselves.

Also, the carburetor would literally break the laws of physics.
