I wonder how many CRT monitors there are out there?
Especially as they all seem to be being replaced with LCDs. Both computer monitors and TVs. I wonder what surface area all the screens in the world would cover, how big a TV could they all be if they were put together?
There are 484 million internet users in the world. Maybe half of them own a computer? Most probably have about a 14″ screen. A 14″ screen is about 100 square inches, about 0.064516 square metres. (Err on the conservative if erred on the optimistic before, there’s lots of bigger screens, but also lots of people who are more than doubled up on computers.)
That’s about 31 square kms. Or a square computer screen 5.5 km on a side, or 7.7km diagonal. It would look quite small from orbit and wouldn’t be much use for working with from there, plus the mouse cord wouldn’t reach.
James suggested that they could be used to make the world’s largest particle accelerator.
