SIMPLE SOLUTIONS for Planet Earth. Plus, in 2009 I published in the Huffington Post:
THE FUTURE OF SUSTAINABLE AVIATION
- Jet fuel from algae by DARPA in 2010, which remains today much, much too expensive to produce.
- A new molecule (right) developed in Sweden to make jet fuel 30% more efficient, also in 2010, but nothing much has happened.
- Last week in Renewable Energy World: A New Path to Affordable Jet Fuel? Please click on that article. Pardon me for being a bit jaded.
So the quest to replace fossil fuel-based jet fuel will continue on parallel paths: biofuel R&D for clean jetfuel and a next generation hydrogen-powered airship. I hope I'm wrong, but I'm afraid this transition will take many decades.
