Thorium – one great solution to our CO2 problem

Imagine a world with safe, CO2 free energy that’s available 24/7.  Science fiction?  No, science fact.  In the 1950’s and 60’s, scientists explored designs for a Thorium-based nuclear reactor.  Unlike today’s uranium-based reactors, a thorium reactor is unpressurized (can’t explode), has minimal waste, and inherently safe, with the fuel draining into a storage tank if power is lost.  Here’s a quick TED talk video that explains this technology more:

So, why was this promising technology abandoned in the 60’s?  To understand this, you need to understand our society at the time.  We were in the midst of the Cold War, and, well, one byproduct of uranium-based power plants is plutonium, which makes great bombs.  Thorium reactors didn’t.  End of story.

One other great part about thorium, is that it’s currently considered a waste byproduct when mining for rare earth minerals, and is incredibly abundant on this planet.  This is not a difficult fuel to obtain.

The following video is much longer but delves into Thorium reactors in more detail if you’re interested:
