At 3 mins 38 seconds I confused the horizontal with the vertical axis. Sorry about that!

What can we do to reduce the carbon footprint of air travel? In this video we look at battery powered planes, hydrogen powered ones, bio fuel, and synthetic kerosene.

Data about airplane emissions come from Our World in Data

The figure for the increase of airplane efficiency is from this report:

The figure for the energy per volume and energy per mass values for different fuels is from this paper:

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address
