I once heard that in some R&D into Venus surface probes, they were considering
using new vacuum tube technology to make the probes last much longer.  Because
tubes don't mind the high heat found on Venus as much as semiconductors do.
These tubes would be something like vacuum "intergrated circuits".  
  Don't know who was doing this, even if this was really being worked on.
  Anyone know?
