     Negative energy is that electromagnetic field that surrounds you when 
     you talk to your employees about the company's current restructuring 
     plans!!
     
     The above are my thoughts only. Any semblance to truth is purely 
     fictional and coincidental!!!

Also has application in radiation treatment. If we could actually do 
negative beams, then we could subtract dose from critical structures 
and optimize patient radiation treatments even more.  Unfortunately, 
we are pegged at the floor of zero weight. However, for some treatment 
planning systems in the past you could enter a negative beam weight 
and get negative dose! A trick for entering a blocked field, but with
incorrect penumbra modelling. Oh well, its still what the doctor ordered!
