Now how silly, I do not know how a jet engine works but I buy GE. I do not know the formula for Coke yet I invest. The software codes are secret yet we buy MSFT etc. I just want to know it works and that there is a market for it!
I dont know anything about the scrap metal industry...so I was wondering what problem are they referring to that needs the solution...is it something about the ground being contaminated from the metals?
