Who is right - the power company or the citizens?In Switzerland there was a dispute between an electric power company and a local organisation of citizens about whether the high-voltage power lines should run above the ground (the option favoured by the company) or below ground. The company argued against below ground lines as these need to be isolated with a gas, SF6 , which is one of strongest known green-house gases. The citizen´s answer to that was that this gas is 5 times denser (heavier) than air and can therefore never reach the upper atmosphere (see SF6 Problem.pdf (in German)). Can you decide who is correct?
