    In the mid 1980s SF6 was about $3-4/lb. Now, in the mid 90s, it is about $100/lb. Since a pound is only about 10 liters, filling up a large insulating tank with SF6 has become a very expensive proposition. The breakdown voltage of most gases can be increased by increasing the absolute pressure.
