Can you use a heat pump to provide the temperature difference to run a heat engine?

Yes, a heat engine runs on heat.

Yes, a heat pump moves heat.

No, heat is not created.

No, the heat supplied does not create a large enough temperature difference.

No, we cannot use heat pump to provide the temperature difference to run a heat engine.

Explanation:

In a heat pump energy is transferred from the heat source to the heat sink whereas in the heat engine energy is transferred from a higher temperature level to a lower temperature level called sink. In a heat engine the heat energy is converted into mechanical energy
