Block the Sun and a Battery of Waste

The crisis of global climate change is causing some researchers to consider drastic measures, including the idea of sending nanoparticles into the atmosphere to reflect the sun's rays away from Earth. But the government of Sweden isn't having it. Anthony and Jeff debate the science of blotting out the sun. Then, what if you could have a battery that lasts 28,000 years? A new startup aims to have a working prototype available in 2 years. The catch? It's made out of nuclear waste. Jeff and Anthony have some concerns.
