====== - Tunnel or Duct Size: Design a tunnel that minimizes heat loss. For example, a well-insulated duct with a cross-sectional area large enough to allow efficient flow of hot air without excessive velocity. ======
* Heat Insulation: Use materials with high thermal resistance to insulate the tunnel, reducing heat loss.
* Air Flow: Ensure the airflow rate is sufficient to transport the heat energy to the furnace.

Assuming the hot air is captured and directed immediately to the furnace:
* Heat Transfer Efficiency: Assume 80% of the captured heat can be transferred to the furnace due to losses in the duct and imperfect heat capture.
