All these thermodynamic calculations can make you very hungry, right? Why don$$t you

prepare yourself a little bit of yummy ramen...?

As you stand on your Q$=2$ kW stove watching the water boil at tc $=100$C in the kettle,

a brutal thermodynamic thought comes to your mind: Isn$$t it an unforgivable waste of

energy to use heat at $($th $=600$C$)$ of your glass ceramic cook surface just to boil water?

$1.$ Use the Clausius$-$statement for the reversible case to evaluate how much power a

device installed between the cooking surface and the boiling water could produce

from the heat flux. What heat rate would be left for cooking your water?

$2.$ Does it make sense to use such a power generating device for stoves in this case?

Discuss cases in which such a device could really be useful; is there already an

invention working as described?
