$200 Trillion global investment in carbon energy sources could lose most of its value.
Those technologies are already available but hidden. Do not believe it? Check out Nikola Tesla, John Searl, Stanley Meyer, and Tariel Kapanadze.
Many of such technologies have been discovered more than fifty years ago. So it is hard to judge when they will be introduced to the public. I think that it will happen within a few years, if not earlier.
This fractional reserve banking system is built on heavy leverage. The introduction of new energy technologies will cause massive devaluation of the carbon energy sectors, hence lead to meltdown of global financial system. It is coming, though it is hard to pinpoint the timing.
Once those technologies are made public, and widely adopted, the Middle East will become waste land. The US dollar will collapse given no more recycling of Petrol-Dollar from OPEC countries. The major beneficiaries will be Japan, China, India, and European countries.
