Yes, kerosene (or some roughly similar hydrocarbon) is hard to replace in air traffic. But 1. Air traffic is something like 1-2% of CO2 emissions. 2. This is an extremely inefficient way of replacing that fuel. It is using resources (a solar energy park, albeit solar thermal) that could be used for much more effective for much more direct CO2 replacements. This is like spending effort for cufflinks when it's -20 C and you aren't wearing any pants. Pants first. Cufflinks later.
