Still, I wouldn't worry about running out of energy.
Nor do I. The problem is high energy prices and shortages. These may not impact our lives much but people pushing the poverty level may eventually
have dire consequences. Real suffering may result.
I once took a graduate level series of physical chemistry courses. In it we studied quantum physics. What occurs at the orbital levels in the atom
looks very much like well, perpetual motion.
Here's what John Ecklin said about it: "It is amazing that in the sub-micro world of the atom, quantum physics requires the perpetual motion of
particles both as to spin and orbital motions. In the macro world, science is based on the law that a perpetual motion machine is absolutely
impossible. This is the state of today's science?"
In other words the particles were spinning around that atom of gold in the pharaoh's tomb in 2000 BC. And they are still spinning the same speed
today. What do you suppose is maintaining their spin? If you can answer that question then you may be able to understand ZPE.
