In the Wall Street Journal today, 11-12-07, page B10 there was an item about an inventor who uses radio waves to light salt water on fire. Also, safety notices state oxygen users should keep petroleum products away from oxygen lines. Is it possible to use a combination of radio waves and pure oxygen to burn off oil slicks like we now have in San Francisco Bay? The very flammable content of the bunker oil has evaporated, but the remaining 'sludge' might be able to be burned off in a very controlled way.
