Do you have any vidios of lasers holding up, say, a 10kg object, for 20
minutes and keeping it under control.  This would be one of the easy
feasability tests one would do at the start of any serious undertaking.
That would be one of many things that would have to be sucessfully tested
before the project would be deemed even possible.
