Can't we use heat's tendency to rise to create energy? Doesn't it displace anything?

I'm talking about the Law of Conservation of Energy, which I believe says that heat is a form of waste and is unusable (but transformable).

Rising heat can be used to lift a hot air balloon with a basket full of people suspended from it. I believe that shows quite a lot of energy created by the rising heat.

Heat is usable to perform work by a number of processes if the object containing the heat has a temperature greater than the ambient (reservoir) temperature. In your example, that would be the air temperature.

i didnt get your question but what you mean by heat is unusable, It is a form of enery and we used and using it in our daily life. you cook things by heat energy, the cars goes by heat energy, the steam train used to go by heat energy and so on

HEat doesn't rise. Heat is not an object. Hot air rises.

The heat generated in your car's engine is due to friction and burning fuel, it is put to good use by the car's heater.
