Our mission is to rapidly disrupt the aviation industry with non-crude based energy and better passenger experiences. In the short term are using liquid natural gas (LNG) and renewable LNG because it is 80% cleaner, and 50% cheaper than jet fuel, >2x the improvement over Airbus and Boeing's latest generation of aircraft. In the long term, will we use natural gas from methane hydrates which can be used to sequester CO2, a process pioneered by the Conoco Phillips, the Department Of Energy and Bjorn Kvamme. The net emissions characteristics of LNG actually are lower than those of electric aircraft powered by the grid without the cost of increase of frequent battery replacements and the cost of building a larger airframe to hold the batteries. The low cost, low emissions characteristics of LNG allow us to reduce a emissions without the need for subsidies and tax and trading schemes.
All these qualities of LNG make it possible for us to build a 4-passenger jet that challenges the unit economics of a 200 passenger (and very crowded) flying bus. By directly competing with single aisle aircraft, the bread and butter of the airline industry, we are able to instigate an industry wide disruption rather than a noble protest that depends on unproven technology. It gets better: the SavionJet works with certified aircraft engines so we don't need to wait until 2030, 2040, or new regulations to come to market deploy.
So the bottom line is that because of LNG, green, private jets are coming to the middle class in the next decade.
