In Mr Savinar's statement : " Thus any plan to aggressively reduce air travel is likely to produce the same sort of unintended consequences that would be produced by an aggressive plan to reduce automobile travel: severe economic dislocations, followed by massive social unrest, ", he describes the AGGRESIVE reduction of both air and vehicle travel. There is no doubt that dramatic reductions from current levels in both vehicle and air travel would most certainly cause severe economic dislocations, which surely would be followed by great social upheaval. Go to Mr Savinar,s website Paul and read the long and very excellent overview of our looming energy predicament. Mr Savinar's information in this regard is completely consistent with the information I have researched on energy in recent years. You state Paul that: " Mr. Savinar is a lawyer, and everyone knows that a lawyer's opinion is worth nothing unless paid for. ". So he is a lawyer, and by your appraisal, then nothing he says or writes has validity? Are simple notions like that really the way you go about judging the world Paul? Mr Savinar's content in his energy crisis overview is very solid. Making a statement that implies that just because Mr Savinar is a lawyer, then the content of information he is sharing on a subject is bogus, is as far fetched as proposing that Air Powered Vehicles will make any meaningful differance at all when it comes to staving off the great energy predicament we are in the early stages of. Are you perhaps a lawyer Paul :-)
