Looking like a regular blimp, the Stratobus is a really interesting piece of kit! With applications including telecommunications, broadcasting, navigation, observation and security, you can see why it is receiving a lot attention. Its long endurance and complete autonomy from a fixed position gives it a leading edge over similar projects. Already having Airbus onboard, the Stratobus could make an appearance sooner than we realise.

It's very interesting that the Stratobus is powered by a fuel cell. Hydrogen is generated through the splitting of water by electrolysis with the energy provided by solar panels. I would be very interested in knowing if hydrogen generation via water electrolysis limited the lifetime of the Stratobus to the quoted 5 years.
