Batman and Ironman

My readers are probably familiar with the popular American movies, "The Dark Knight Rises" and "Ironman".  Both of these movies have novel energy sources woven into their plots.

In "Ironman", Tony Stark and his flying suit are powered by a glowing ring device that produces vast amounts of energy.  

In the latest Batman movie, Bruce Wayne has a fusion reactor underneath the Hudson river that is only awaiting the final touches of a genius Russian nuclear physicist to make it work and produce limitless, clean power.  Of course, the device falls into the hands of the arch villain, who immediately weaponizes it.

How does movie land compare to reality?  Check this out:  A piece of thorium (an element, present since the creation of the universe) the size of this rock can provide all your energy needs for your entire life time.


 That's right, energy for your entire lifetime; transportation, domestic heating and cooling, domestic hot water, lighting and electricity.  Compare that with the truckloads of coal, oil and gas you would need for a lifetime. 

Thorium is a fairly abundant element, as common as lead and can be burned a a molten salt reactor.  These types of reactors offer substantial advantages over conventional light water reactors and yes, Virginia, even light water reactors have advantages over fossil fuels.
