Spade is alking about absolete tech. Stirling Engines can be used to generate at even lower temps than 95 deg C.
What matters is the temp difference between hot and cold plates, but to make it more efficient, there are ways to cool the cold plates even more, essentiallyfor free. One of them, a low-tech fridge/freezer buried in the ground, uses windchill through coils of copper pipes, heat exchangers and so on. It requires practically no energy to operate, just a small battery, yet you can freeze stuff with it !!
