WebJul 27, 2024 · William Thompson, the first baron Kelvin worked out that the Earth was around 20 to 400 million years old, based on the rate of cooling from an assumed molten state. This would imply that the Earth's primordial heat would already be essentially lost, so you could argue the answer is zero (assuming Kelvin's calculation remains reasonable).
