The major source of Gallium--a several century supply is bauxite. Copper is a lesser source. Many coals are "high" in gallium and so ash from power plants should be an excellent source.
Everyone here has chosen the "technical ladder". It has taken most many years of education and experience to reach a high level of competence. Two problems exist. 1) little or no job security, retirement benefits, etc. and 2) an almost impossibility to explain anything to your Boss or his boss. OTOH an affable manner, and a BA degree in political "science", history, or business goes a long way today. There is no incentive to develop intellectual capital except love of the field.
