   Lets say that a laser(and other equipment that needs to be replaced every so   
   often) can be used 10 years before needing to be replaced, there are 2   
   launches every day, and that all of the cost is from the 472 million dollar   
   laser array.(probably can get    
   better info from Atomic Rockets but I don't have time for that). Each launch   
   consumes a megawatt and takes 1 hour, so it takes $120 per launch if we are   
   drawing power from a US grid(12 cents per kw-hour). Each launch can lift 10kg.   
      
   10 years = 3650 days * 2 =service life: 7300 launches   
   $472,000,000/7300 launches =(around) $64657.5+$120(electricity c   
   st)/launch(10kg) = $6477.75 per kilogram. According to Atomic Rockets, the   
   1966 Proton has $5000/kg launch cost.
