Yeah, let's think about that.

In this video[0] of an open-pit mine, Sempertrans claims their conveyors move 6 meters per second,and elsewhere[1] they claim to move 18,000 tons an hour, ie 5 tons per second—just under 1 ton per meter of belt? It must be pretty dense, something like ~800kg/m^2? That checks out for cubes of lignite.

So only 198,000 such conveyors are needed in world.

Not sure what math gets you to 198,000 belts needed?

If this belt can do 5 tons per second, that's 10,000 lbs per second per belt

So to reach 1,000,000 lbs/s globally, you would do:

1,000,000 lbs/s divided by 10,000 lbs/s/belt = 100 belts

No?

Makes sense. Can't tell you what I was thinking, since the cache has cleared. ;)
