Just about everything is against me with this method, BUT you do give me an idea... You got me thinking about the possibility of actually mounting the TCXO burried in the ground! The temperature of that is not going to change very rapidly. FWIW, I know a guy that did work as an air conditioning engineer,, but now works for a company selling geothermal heating. He installs ground source heat pumps for the geothermal energy. He says that they actually work quite poorly in many cases. In a couple of years the temperature of the ground falls as the heat is extracted faster than it replenishes. So the efficiency falls off. I don't think that the TCXO would heat the ground faster than it dissipates away. Of course there would be some practical issues burying the TCXO, but those would not be insurmountable ones. I have no idea what depth might be needed. My wife thinks thinks I am a nutcase - that would only confirm it to her!
