(MOD NOTE: Started a new topic for this discussion to continue. Please remember the 'no sci-fi engineering' provision of rule 1.9. Have fun!)
Also, since I'm thinking about surface operations on Venus, the state-of-the-art in high temperature electronics has advanced quite far in the past decade. Its now possible to buy off the shelf chips from vendors designed to operate at the 250-300 C range. Meanwhile basic functionality has been tested at and beyond the temperatures needed for long-term surface operations on Venus: http://www.grc.nasa.gov/WWW/SiC/ http://www.gizmag.com/extreme-silicon-carb...ctronics/16410/ http://www.grc.nasa.gov/WWW/SiC/publicatio...Contact2010.pdf Another decade or so and a long-term Venus lander could be possible with (practically) off the shelf electronics! |

^ Yeah, JFETs don't need that gate insulator. They also only had n-type, so of CMOS, they have MS. Nothing people haven't worked around in the past to make large devices. But, unfortunately, at the 10um geometries I poo-pooed earlier and with really low reliability, which isn't something that's easy to work around. Infinite money and access too commercial dev fabs, though... sigh.
