Very puzzled by this, there is no evidence that they have a solution that is commercially viable yet all these executives are being appointed. It isn't clear if they are leaving their current positions to join SolarWindow or adding to their list of jobs.
If Mr Rhee can actually demonstrate to the world (CES would have been a good spot but there are other conventions he could choose) a viable system - 20'x20' pane for example we would have a major winner here.
