I have an ex girlfriend who is a burns nurse and i've visited her at work a few times. Plus i've been to the children's burns unit at Westmead Hospital and seen some pretty heavy shit there.
If this works, it will be revolutionary. Unless you've seen it or felt a burn, you cant imagine how bad it is. Especially with kids.
The only down side to it would probably be that it wouldnt work on full thickness burns, (3rd degree burns,) as the lowest level of the skin would be dead and the new cells would have nothing to graft themselves to.
But one of the many plus' would be that any doctor could use it, not just a burns certified doctor.
