A long wire was released from the space shuttle. Indeed an electrical potential was created and electricity could be harnessed from the process, but the energy came from a loss of gravitational potential energy. In essence, you can't get that electricity for free because you need to spend fuel to get to the apparatus into position again, and there's an inherent inefficiency associated with that.
