Some ideas:
- A fast way to dig holes, if ‘soil’ or ‘stone’ is an object.
- Annoy physics teachers – move in and out to drive a piston. Perpetual motion!
- Moving day is easy.
- Server farm.
- Safe house.
- Is momentum conserved? Not sure how general relativity would work. Win a Nobel Prize.
- Building stuff in space just got a lot easier and safer. 27 cubic meters of free payload!
I only occasionally see that here in Asia. It exists, but I feel like it’s much less. I immigrated here maybe 12 years ago from the West. The overall level of violence is much lower than I grew up with (even in Canada).
Most young people I know consider handling guns more of a chore. In Vietnam, learning to disassemble, clean, maintain, and reassemble an AK-47 is a mandatory class. My wife got top score :)
Anyway, we stumbled on a great way to make guns uncool, I think. Personal possession is illegal here except for shotguns, it’s for some very specific scenario that I don’t exactly recall. I knew of some remote workplaces with one, in case of wild animals. We get some, but not many, illegal firearms.
