Just saw Exon's quarterly statement - if the price of a barrel of oil is $100, then $30 is profit, with less the 2% being spent for renewable energy R&D. Yes they spent $35 of that barrel for taxes (here and foreign). I understand that Exon is in the oil business, not the renewable energy business - but- the argument to Drill -Drill - Drill is not the answer to our energy problem. I need a scorecard to know who the players are. Are the oil companies in bed with the auto industries. I cant remember any major improvement in the combustable engine since Henry Ford - maybe some minor gas(mpg) improvement recently, but nothing major. this is very confusing how we can send men to moon,atomic bomb, jet planes that can do almost everything except think (maybe thats just around the corner)We have come from wired wall phone to cell phones that do everything, yet the combustable engine remains the same,. If there is no way to improve the engine then give up and find a new way - wind, tide, sun, etc . Its all money, money, money, but thats the capitalists way, and i would not want to change that - maybe twick it a little. Now that i am venting my anger on big bus and who is who, and who is in bed with who. I seem to have read that in WWII we had jets that landed in the Philapeens, in typhoons, at 150 mph on two wheels and stayed on the runway. I drove a car with four wheel at 30 mph that if someone spit on the street i would slide off the road - oh maybe they a abs brakes which Detroit felt i did not need - dumb- maybe that 30 lb battery that lasted all of three or four years then went into the garbage dump, was the best that Detroit could do, but that was just about the time we sent a rocket ship to Mars which sent back picture for years yes years with a battery about the size of your finger nail. I am so confused
