Extending this line of thinking to conventional aircraft suggest to me that we'll be completely grounded before too many more years pass. Who's going to be willing to pay $10,000 one way to travel across the country in 20 years? New energy sources will undoubtedly be developed, but I can't see this happening AND is being adapted to to aircraft in 20-30 years. I read an article a while back that believed that by 2030 there would only be able 30 airports still active in the States, down from about 300 today.
