My interview with this solar thermochemistry pioneer in #solarfuels made me realize that real world innovation (as opposed to designing apps, for example) that requires engineering, chemistry and physics can take a couple decades and the work of many STEM researchers

But getting aviation #CO2 #emissions to zero is necessary to a future #climate we can inhabit. This year, this jet fuel from CO2+H2O powered by solar mirrors finally made news at the BBC, CNN, WSJ, etc
