Elon Musk’s five insights into solar energy

[PamW]

9. CRAPPY Mathematics

Something is ONLY "inherently exponential" if the first derivative or rate of change is proportional to the quantity itself. That is the quantity itself "x" is the solution of a differential equation of the form:

dx/dt = cx

For example, radioactive decay is inherently exponential since every radioactive atom is independent and has a fixed probability per unit time of decaying. Therefore, the rate at which atoms decay is proportional to the number of radioactive atoms since each is an opportunity for a decay.

Neither you nor Musk has presented ANY evidence beyond your own I'll-considered FANTASIES as to why there should be the above proportionality.
