I thought there were possibilities using lasers or microwave.
HAH! I thought this was possible using a geosynchronous orbit. I had imagined it would need to be much bigger and sturdier. But would the atmosphere of the Earth somehow disrupt the orbit? I am thinking that the ribbon would have to be slack....because if strong enough winds push it, it could slow down or speed up the anchor at the space end just enough that the orbit could deteriorate.
