> Or we might move to a mix of electricity and hydrogen fuel cells; Toyota's betting on this, since natural-gas refining releases waste hydrogen. Safe containment of hydrogen is harder than safe containment of gasoline, though... It is possible to do a gasoline fuel cell: https://news.wsu.edu/2014/06/16/wsu-researchers-develop-fuel-cells-for-increased-airplane-efficiency/ https://news.wsu.edu/2014/06/16/wsu-researchers-develop-fuel... https://www.researchgate.net/profile/Jinsoo_Kim8/publication/263700298_Gasoline-fueled_solid_oxide_fuel_cell_with_high_power_density/links/54e15ee90cf2966637928e62/Gasoline-fueled-solid-oxide-fuel-cell-with-high-power-density.pdf https://www.researchgate.net/profile/Jinsoo_Kim8/publication... Output seems to be water and carbon dioxide; not perfect, of course, but much better than current IC engines, and no infrastructure to change. But there must be a reason why we haven't heard about them more since 2014 - still must be a lab-only thing for one reason or another.
