There’s no fortune to be made. Even if you have a new energy source that costs the same as today’s and emits no CO2, it will be uncertain compared with what’s tried-and-true and already operating at unbelievable scale and has gotten through all the regulatory problems.

Without a substantial carbon tax, there’s no incentive for innovators or plant buyers to switch.

Since World War II, US-government R&D has defined the state of the art in almost every area. The private sector is in general inept.

The climate problem has to be solved in the rich countries. China and the US and Europe have to solve CO2 emissions, and when they do, hopefully they’ll make it cheap enough for everyone else.
