leon, when I asked the question, I was asking about large-scale power storage ... a PACEMAKER doesn't count in this argument, it uses a battery and a small generator (got that from a Google search)... I'm talking about scales in many MWh or GWh...
Energy storage on the power grid is not very useful when we generate the power through gas turbines, but we use some power-leveling (some high power consuming companies/factories are encouraged to use more power during the winter, and much less during the summer when consumer usage increases)
