- -Hmmm, well, I guess if we were to make any kind of serious exploration of
- -Venus's surface we would have to develop electronics componants that
- -operate comforably at 900f.

- A sterling engine (running off of a VERY hot RTG, so as to get
- reasonable efficiency when the exhaust is coming out at greater
- than 700 K) used to run a refrigerator that cools equipment inside
- a dewar flask to workable temperatures appears doable.
