3. Assume the lowest temp accessible to the engine is the ambient environment at 300K. Hot Coo a. Compare the thermodynamic efficiency limits for heat engine operating from 150°C and from geothermal source Magma at 1000°C (0°C + 273.15 = 273.15K) b. If we use a heat pump for the heating for a house with a geothermal source of 150°C, for every 1 unit of heat provided in the house, how many units of fuel energy is consumed in the fossil fuel power plants whose average efficiency is 33%? Mm
