Can't find the video I saw but the subject is on the web Even if that's not feasible, there could still be another as yet undiscovered energy application if it can allow access to parts of the structure of the Universe normally out of our reach Another story I read today about researchers using 300GW laser pulses to make a supernova by vapourising carbon.
