But what if they use BadBIOS to beam into space on a microwave carrier
   by modulating the PSU of all infected laptops at once?!

     Wrong lesson. Windows was used, but was not necessary. The lesson
     here
     is to reinforce the airgap with restrictions on who and how software
     and
     hardware is connected to critical systems. No critical system should
     be
     connected to anything other than it's own closed system unless there
     is an
     absolutely unavoidable reason (such as code repair). Where the
     system
     must be disturbed, nothing that connects to the protected system
     should be
     unexamined prior to connection, and the examination should be
     meticulously
     performed, by qualified personnel (and there should always be a
     lab-duplicate upon which all such events are dry-runned).
