Presently, most fossil fuel burners use plurality of parallel pipes within the ground surface outside ambient air, however by mixing hot air with a beneath the pavement layer, the pipes carrying air and fuel as oil, coal or gas, less fuel is burned to achieve the transferring heat between the ground surface and the 25 same results.
