Here is a little gem so obvious that Blind Freddie would not only see it but would immediately invest in it…

And it is so simple.

• Extract out of the ground fossil energy
• Heat it so that it changes its structure into material that can be molded into infinite number of useful objects and then manufacture them on mass.
• Sell these useful items to consumers, ideally so that they use them once and have to go and buy another one the next time they need it
• Let the used item fall away into whatever waste system is in place
• Rummage around in the waste to find the used useful items
• Reheat them again so as to make another even more useful material
• Sell this useful material and make roads out of it
• Ignore the obvious flaws in the gem
