The Carnot thermal efficiency is used to calculate the theoretical thermal efficiency of a heat engine. In thermodynamics a heat engine is a system that converts the heat energy into mechanical work (or electricity). By the second law of thermodynamics, such a system must contain a heat sink and a heat source. T cold is the corresponding temperature of the heat sink/cold reservoir and T hot is the corresponding temperature of the heat source and the Carnot thermal efficiency formula is as follows:

The temperatures in the formula above must be converted to degrees Kelvin, so the Vulcan published figures [Source: VUL AGM presentation from 25-11-2020, page 13] of 165 degrees C for the heat source converts to 438.15 degrees Kelvin and 65 degrees C for the cold reservoir converts to 338.15 degrees Kelvin.

Plugging in the numbers of 438.15 degrees K for the heat source and 338.15 degrees K for the cold reservoir, the maximum possible thermal efficiency of this system (the efficiency at which it can convert heat into electricity) is 22.8%. In practice it will be less than that, so assume 20% or less.

Exactly. ... others and myself pointed out this basic thermodynamics some weeks ago and we were branded as ‘downrampers’ by the blinkered zealots.
there are positive aspects, but lets temper things with reality and likely risks.
