I’ve worked with many Engineers with whom I don’t see eye-to-eye, I guess you have too, and we get along just fine. To me we should not be using sun inherited energy, which are stores of energy we can’t replace, unlike oil, which we can functionally replace for our purposes with hydrogen generated directly from solar. Volcanic energy, and the kinetic energy of our planetary rotation are sun inherited energies, we should consider them sacred because we can’t replace them with any known technology. It isn’t important that we agree on everything, much better we critically analyse one another’s work. What do you think of "Kardashev money"?
