It sounds cool (or perhaps, hot), but steampunk photo/video transmisson? I don't see it.
Just send an RTG and enclose the main electronics in a peltier chamber or other heat-pump. With plenty of radiator surface.
- jagged-chisel 6y agoThat's going to help only if the radiator surface will get hotter than the atmosphere before the main electronics get too hot to operate.

- mhh__ 6y agoMechanical TV does exist, so you could still reduce the amount of electronics along those lines.
- lhopki01 6y agoThey specifically mention the issues with an RTG in the article. The high surface temperatures make radiating the excess heat off very hard. Same holds true for any sort of peltier chamber or heat-pump.
- jacknews 6y agoHard, but not impossible. TEG modules are available with the hot side operating at 800C, so I'm sure TEC modules can also be built with hot sides well above ambient on Venus.
- FatalLogic 6y agoThere are obviously chemical-based processes for recording photos and video. They can be adapted for high temp. Balloons can be used to lift those records and other data high into the atmosphere, where temperatures are lower and they can be recovered and converted to electronic data by more conventional vehicles. It's very, very difficult, but not impossible.
