Thank you but it was too technical for me to understand

They say it is impossible to manufacture a ideal engine. First what we require is a source with a infinite thermal capacity.So to keep its temperature constant we can add external heat to it. By that way though we take heat from it its temperature will remain constant. Similarly for the sink we can use a coolant constantly to keep its temperature very low. Is it possible to do that. I am just 15 years old. So please dont mistake me if my question is ridiculous
