comment Gravitational potential outside Lagrangian points or Lagrange points
Thanks a lot, AlanSE. That explains it very well. +1 for explaining the equation too!

comment Gravitational potential outside Lagrangian points or Lagrange points
It was from csep10.phys.utk.edu/astr162/lect/binaries/accreting.html seemingly from a University of Tennessee lecture. The accompanying text states specifically, "The gravitational potential energy for a binary system is plotted in the adjacent diagram."

And he had 2 units named after him: sizes.com/units/siemens.htm

comment Gravitational potential outside Lagrangian points or Lagrange points
Thanks for the explanation. I'm not much concerned about the stability at L4 or L5, but rather the implications on movement far away. The surface slopes downwards (in fact at an increasing rate) far from the ring. Does that mean that a free body there will move away from the masses?

Likely. Perhaps you could look into other ways of cooling your home instead, such as setting up sun shades or atomising water in front of a fan: yardsurfer.com/outdoor-misting-fan

@zephyr: Not necessarily true; there are many reasons why a company may not go into a certain line of business. As the Wikipedia link shows some companies do do that, it not only shows theoretical possibility but actual viability.

comment Underground explosions due to plate tectonics and natural gas pockets
It's likely that parts undergoing subduction i.e. active regions at the fringes of the tectonic plates don't have enough time to build up substantial reserves of oil or gas. It's the stable areas far from plate boundaries that manage to build up reserves over time.
