So all I need to do is place a carbon fiber brush at the extreme (highest point) of the moving platform. Then I provide a connection like a wire from the brush to a clamp which will be clamped onto the metal frame of the treadmill?

We were not told the environment. Could you rephrase that please? I don't really understand it.

static electricity is a buildup of negative charges on an object. When it's discharged that means the negative charge is trying to balance itself out. Shuffling feet on carpet is friction which cause negative charges to build up on you (the person). When you touch a metal door knob, the door knob isn't grounded, so instead of running into the ground and dispersing, it balances itself out by creating a spark which is what you are feeling. This is what we have learned.

We are doing a project on static electricity that is being built up from running on a treadmill. We have to build an invention using the idea of a lightning rod to get rid of the static charge (in other words kill the charge). We want to kill the charge because the person is getting shocked.

So I would be able to run a wire into the ground part of part of the outlet without having to use the other two parts?

I am doing a project in science, and I need a device that is able to kill a static charge. I used to have it so the charge would run outside and run into the ground through a copper rod, but my science teacher said that I need to find a way so that I don't need to run it outside. The reason I can't find it myself is that whenever I search up "Device that kills static charges" on bing or google, all I get is websites saying if you can get killed by static discharge or not. Thanks!
