#2 Obama science team approved...
The AP1000 is one of a new generation of nuclear plants that use passive measures such as gravity, evaporation and condensation to remove excess heat in an emergency.

John Holdren, Obama science advisor, advocates Large-scale geoengineering projects designed to cool the Earth, such as shooting pollution particles into the upper atmosphere to reflect the suns rays.

#3 There is actually a lot of good news on the nuclear energy front. There are some previously licensed plants that were never built after Three Mile Island that are now being built by the Tennessee Valley Authority and there are a couple of plants where construction was completed but were mothballed that are now being started. Looks like 2012 will see the start of a major ramp up in nuclear power generation in the US after a 20 year break.

#4 Remember, energy can be as cheap as chips, but if comparative advantage is destroyed by transfer taxes the economy will still SUCK.

#5 The quiet revolution in nuclear power is in small, very low maintenance systems. These are in development by no fewer than five major companies.

Some are more like typical small reactors, needing a staff to function and for maintenance, giving a medium small amount of power for a very energy consumptive corporation or a few.

But the most interesting from my point of view are those about the size and shape of a large shipping container that are factory sealed and kept underground in a concrete pit with a concrete slab lid. They have just two above ground cables, a large, electrical output of DC or AC and a smaller diagnostic cable that goes to a computer.

Typically, such a reactor would provide power for a 5 square mile mixed use central city area, or a 10-20 square mile mixed suburban use, for a set time, after which the lid would be removed, and the reactor sent back to the factory, a new one put in its place.

#6 As I understand it, this is an advanced 3rd generation (3G) reactor. It will generate about the same amount of electricity as the earlier 3G designs but should be easier to build, safer and have indefinite on site storage of rad waste.

The PRChina has 4 of these under construction.

But I agree w Moose that a 4G design that can be mass produced would be a real game changer in a good way.
