Idea!! Stupid or Genius??

Probably.

After it’s all said and done, solar conversion to electric power might be 15% efficient. Using electric power to heat water is not efficient. A better way is direct solar heating of water. Granted, it may not get hot enough for coffee, but it won’t take much more energy to get it boiling.

actually the genius idea is to heat water with the engine in a mobile application.
Instead just venting heat with the vehicle heatsink, you just add an exchanger to heat a lot of water.
if you got a well insulated tank, you can probably keep almost boiling water for hours.
Actually temperature is not very important, because you can top what is missing with another energy source.

Yep. Best idea in the thread.

If you want to go deep you can also cook your dinner while driving using the same principle. A copper pipe wrapped around the pot does the job.

or just remove oil from the motor, after a few miles you should be able to cook anything directly on the hood

Maybe has potential!
A lower efficiency is made up from only heating what you need and the convenience of not having a separate tank. Very relevant for a RV.
Induction heating may be better.
With the acceptance of LiPO4 on demand heating is a possibility and we may even see the gas in instantaneous HWS being replaced by an element.
Or with dual option....gas or an insane button for when your batteries are full.

Back in the 1970’s someone put out a cookbook for the VW square back.

It told you to drive so many miles at a certain speed and then pull over, open the engine hatch, and set the prescribed amount of food on top the engine for a set amount of time.

With a sufficient amount of beer to wash it down it worked just OK. ?

As this topic lingers and diverges, the jerk in me needs to reiterate that the original concept is a very bad idea.

The mention of induction heating is less viable than standard practice. Induction is the most effective way to transfer heat to a ferrous material in a contact or contactless (but in very close proximity) method; however, a resistive heating element completely immersed in the substance being heated is more efficient than induction.

Here's the most efficient way to heat water with electricity... I was shocked when Google actually returned results:

That makes total sense if your presumptions are true. How sure are you about those presumptions? Also, just thinking logically: a microwave can be applied to the entire mass of water at once, whereas a heating element is limited to a degree by its locality within the water -- hearing the molecules immediately nearby first and then relying upon those molecules to transfer the heat further on down the line.

Conservation of energy | Definition, Principle, Examples, & Facts

Conservation of energy, principle of physics according to which the energy in a closed system remains constant. Energy is not created or destroyed but merely changes forms. For example, in a swinging pendulum, potential energy is converted to kinetic energy and back again.
