"They have 33 million barrels of storage capacity at Ras Tanura and another 17.5 million barrels of storage capacity at the export terminal of Al Juaymah"

I disagree on this point and I will elaborate: The oil could be pumped back into the ground of a depleted oilfield of high porosity where it would be possible to inject water and easily extract that oil again. Voila: a big oil tank. And how big? Massisve? It took me 45 seconds to formulate this idea so feel free to shoot me down:-)

Marco.

The oil loss, back into the reservoir, would be too high. This is really a function of grain size and permeability in the reservoir. Some of the oil would be left behind in the pore spaces in the rock. Note that this is not a factor in tanks farms and underground salt caverns.

I really need to order, from amazon, that book you reccomended!

Why do I envision in my mind's eye a giant squirrel wheel with a gigantic squirrel running madly on it?

HONG KONG -- A health club here is hoping that a car battery, some StairMasters and dozens of gym rats can help ease the world's energy problems.

Rita Wong is doing her part. One evening recently, the fit 27-year-old, dressed in black spandex, pedaled furiously on an elliptical machine at the California Fitness health club. As she worked up a sweat to a Madonna song blasting on the gym's sound system, the energy she created was transformed into electricity and stored in a battery that powers some of the gym's lights.
