I love the idea of thorium, but I think ramped up solar along with battery storage will win the day, because it is installed and working in days, it can be done cheaply by individuals, has good payback in Australia and southern USA and within the next few years once it's cheaper in Boston and Berlin, it's ubiquitous. Since the panels will have come mostly from China anyway, they will by far overtake the West. They can generate solar in Southern China, the Tibetan Plateau as well as the Taklamakan desert and take it north.
Do you also think the Indians are going to wait 5-15 years for thorium to clean up air pollution in Delhi, or are they going to jump to solar and e-cars as fast as possible? India can be very agile if they want to.
