my uncle worked at tva for many years and retired from there...made lots of $$ there. the swiss sell power to germany as the water flows down every day as it makes more than switzerland needs.and then pumps it back up at night when power need is much lower. my daughters fiance is swiss, we go over a few times to visit, his dad told me all about this plant last trip. Im due for another trip...but my wallet aint..you can do a month in italy for what a week will cost in switzerland will cost.I love italy oh so much.
