Could small modular nuclear reactors be the “Game Changing Technology” in the fight to reduce carbon emissions? (Podcast Episode #70)
In this video podcast I discuss the role of the social media in the unrest in Iran. I also speculate about how the B&W mPower reactor and other small modular reactors might be a key to reducing CO2 emissions.

For quite some time I’ve been debating the argument that nuclear energy is equally “renewable” as energy derived from hydro, wind, and biomass. My thought process goes like this…
Rivers go dry with over use and periods of drought, and winds shift with changing weather patterns such as those that will occur with global climate change. The availability of biomass is dependent on favorable weather and must be replenished using agricultural processes that are reliant on fossil fuels. The ultimate energy source of all these “renewables” is the sun, and while the sun is not “infinite,” it is unlikely to extinguish during the course of human existence. The ability of the sun to replenish hydro, wind, and biomass make these energy sources renewable.
In contrast, the source of nuclear energy is fuel contained entirely on planet Earth. And while there are a finite number of uranium and thorium atoms on the planet, the supply will last for as long as human beings need it. The myth propagated by the anti-nuclear crowd that we will run out of fuel for nuclear reactors is simply untrue. They grossly underestimate the amount of uranium that exists, they discount already proven technologies like breeder reactors, and they ignore the existence of thorium, a fuel even more plentiful than uranium. We have sufficient nuclear fuel to last for more than 1,000 years, even if we expand the number of nuclear plants by more than a factor of ten. This makes nuclear energy inexhaustible.
