At the moment I'm working on two big projects. One is a solar airship, like a Zeppelin, 150 metres long and fully solar, that will be able to drive electric engines and fly around the world non-stop only on renewable energy with absolutely no fuel. This will be a first because the Breitling Orbiter models all burned some propane. Solar Impulse burned no fuel, but even though it was a non-stop flight we had to make some stop-overs. Therefore, the next obvious step is to fly non-stop around the world with zero emissions and just renewable energy. That would be a fantastic journey to speak about in schools, universities and governments and promote all these solutions to protect the environment. The second project that will likely happen a couple of years later, is to fly around the world in a hydrogen airplane, a two-seater, fully clean. You will now probably say that I always fly around the world, and that's true. I love to fly around the world because it's the ultimate flight. You cannot do more and cannot do better! And if you want to prove the maturity of a new clean and sustainable technology, I think it's the best way to do it. So this is what I'm currently working on.
