   Remember that those values are for when you generate steam that you will   
   either need large, strong, heavy tanks to hold, (a tank at 10atm would be   
   a minimum of 32m across to hold 1000t of steam, it would also be ~450K),   
   or that you have to vent to create a nice IR emitting cloud that's   
   following you around.

   Using input values that are utter BS.

   That just means that the heaters are biological rather than electrical.

   Nope.  Further, this entire line of discussion is nothing more than a   
   meaningless digression.  By now you should understand what I meant and   
   the only further discussion beyond this post on my part of other ways of   
   interpreting it will be to call you out on using the digression as a   
   smokescreen and to accept your concession of the point.

   I was using the term in the sense of the use of language to persuade or   
   communicate.  Not that you complaining about a word choice there is   
   anything but a pointless digression that will, at best, head out into   
   more semantic quibbling.

   Asked and answered in another post.  What's more, it's a post that you   
   clearly read because you used information from it.

   The sensor platforms we are talking about are to interplantary war what   
   frigates were to Napoleonic naval war. (or radar stations and satellites   
   are to modern war).
