Energy Tax Prevention Act this bill would have amended several core components of the Clean Air Act (CAA). Title III of the CAA would have been amended to have the term “greenhouse gas” include: water vapor, carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons and any other substance subject to, or proposed to be subject to, regulation, action, or consideration under this Act to address climate change. The Act said that the Administrator of the EPA may take no action involving the consideration of greenhouse gases as pollutants or contributing factors to climate change. It also said that “[nothing] shall cause a greenhouse
Sulfur hexafluoride the gas's large molar mass. Unlike helium, which has a molar mass of about 4 grams/mol and gives the voice a childish and a "chipmunk like" quality, has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, giving the voice a "demonic" quality when is inhaled. For comparison, the molar mass of air, which is about 80% nitrogen and 20% oxygen, is approximately 30 g/mol which leads to a speed of sound of 343 m/s. Sulfur hexafluoride has an anesthetic potency slightly lower than nitrous oxide. Sulfur
