Is China now the dominant superpower?

And let's not forget the strides being made in nuclear fusion.

The technology described the other day as "perpetually just around the corner"? http://www.popularmechanics.com/scie...ma-reactor-ai/

Wrong. It's still in it's early infancy.

I don't think so.
For wind turbine blades to spin there's a minimum percentage of energy that must pass through and cannot be exploited. More effective gearing can be attached, larger and larger blades can be made etc but that's just tweaking the basic technology.
Nuclear energy is the best and the worst solution.

Well FarangRuMak, history suggests otherwise with technology getting smaller and more efficient.
