Actually he has thought about that too. Ever hear of super critical water [pressure > 3200 psi and temp > 705 F]. It has an amazing property of not producing heat under those conditions. Makes the ice age much more likely.
Wow, that’s interesting. And out of curiousity, what vessel would hold the water at said 3200 psi. It couldn’t be the world itself because if the atmosphere was somehow holding the water at said pressures, you would have pretty much any non-rock material dissolve under the oxidize pressures of super critical water (not to mention the temperature).
You would have pretty much the same results as I said in my example, extremely hot temperatures, extremely high pressure and, if the super critical water pressure theory is correct for the flood waters, you would have hyper-oxidation reactions happening that would dissolve everything.
Like I said, Venus would look like a mild climate in contrast.
Any substance at a constant pressure and temperature (below nuclear fusion minimums, of course) will not “produce heat”.
