I think Prof. Hamilton's statement on Saudi Oil Reserves may be a bit misleading. I don't know what the Saudi Oil Reserves are, but at the meeting in Johannesburg last week, Ray Tillerman, Pres of Exxon/Mobil was quoted that " Oil reserves are 3 trillion Barrels" while there are 7 trillion barrels yet to be discovered.

It looks to me like Prof. Hamilton was promoting the Oil Shale thing and was not up front about all the Oil Reserves.
