How come no one has invented something small and/or wearable or something that can save people who fall from high places?
What are the difficulties?

>>8960236
We have. It's called a parachute

>> No.8960244

No antigravity.

doesn't work for 50m fall

Yeah how bout something that doesn't only work from the stratosphere or some shit

just don't fall from low places, retard

september 11 created a lot of crazy things like this

The forces involved in safely stopping something moving at terminal velocity using a "small/or wearable" package.

Redirect it to the ground instead of the person

by what method?

I don't know...
There must be something to does that.

if you can find a method of transferring inertia from one body to another without accelerating either body then you'll get the nobel prize every year for the next decade

>> No.8960392

>>8960338
To be fair he can accelerate the ground and the mechanism all he wants, the Earth isn't budging from one person falling 100 feet. But I otherwise agree.

The problem with September 11 was that the exit stairwells filled with smoke. What a person needed was not a rappelling line, but a gas mask.

The windows were also designed against hurricane winds and bird strikes. You couldn't break them with a sledge. People jumped from the roof because they couldn't open the windows.

>>8960392
Technically it does on some very minor order of magnitude, and so does the person. The only way to stop safely would be to transfer the inertia to the earth and just get the whole reference frame moving at very nearly the speed you are in the instant that you land.

so you want a foldable kite that lifts human weight.

>>8960236
... Usually people who are falling from high places make the conscious decisions to do so? The demand for compact fallstoppers is pretty low.

Those wind turbine guys probably would have liked an invention like it.
Also all the people that work in construction.
