"Just Wondering" wrote in message news:[email protected]... 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. ---------------------- Not so. https://phys.libretexts.org/Courses/HACC_Central_Pennsylvania%27s_Community_College/Astronomy_103%3A_Introduction_to_Planetary_Astronomy/13%3A_The_Sun/13.04%3A_Nuclear_Fusion Gravity is an enabler to overcome electrostatic repulsion, but not a sine qua non for fusion. https://en.wikipedia.org/wiki/Inertial_confinement_fusion https://en.wikipedia.org/wiki/Thermonuclear_weapon 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. https://www.astronomy.com/science/ask-astro-how-do-stars-make-elements-heavier-than-iron/
