About Aviation, but interesting stuff about hydrogen and biomass

Did a back of the fag packet calc a few years ago and reckoned biofuel for planes would use about 25% of the worlds useable agricultural land.

Prof. Brian Cox did the same calculation, but got a different result.

At today's global energy usage, all the biomass on the planet would last 400 days.

Plants will convert about 0.25% of solar energy to biomass, PV will easily convert 10%.

 

Is anyone seriously suggesting that biofuels should power commercial aviation? Last I heard most research was going into synthetic fuels that would, in the future, be based on green hydrogen - though that's not going to be cheap.

It's hard to eat electricity though.
