• Uses hydrogen for lift, which can easily be produced by electrolysing water using photovoltaic energy

• Can be driven by electric motors, which are much more efficient than any combustion engine

• Lots of area for thin film solar panels to power them

• Can be designed in ways to prevent potential Hindenburg-like incidents

• Air travel without huge CO2 emissions

• Quieter and less hazardous to birds
