   If you want to be pedantic, all power is ultimately gravity power.   
   I was going to say all power is ultimately solar, but even the   
   fusion that powers stars (and creates the radioactive metals used   
   in nuclear power) is the result of gravity compressing the star's   
   contents.  But that's not what anybody normally means when talking   
   about solar.

   Gravity is an enabler to overcome electrostatic repulsion, but not a sine   
   qua non for fusion.

   Iron and nickel are the end products of fusion, beyond them it becomes   
   endothermic. The heavier elements are formed by neutron capture in   
   supernovae, neutron stars and nuclear reactors.
