ABSTRACT:
A method of making hot air in the range of 200 degrees (F) from the sunlight striking the paved surface of a parking lot is described. The transparent surface is above an opaque surface forming a homogeneous solid. Beneath the pavement are parallel pipes for the movement of air. The air is compressed into the pipe and sucked out of the pipes via photovoltaic powered fans. Due to the heat transfer through the walls of the pipes, ambient air is made hot. The hot air can then be used economically as precombustion air to a typical fossil fuel burner as oil, coal or gas. While the hot air would not be able to provide enough heat to power an entire power plant or oil refinery, the net result is more efficient fuel burning, with less air pollution produced, perhaps reducing fuel consumption by 5 to 10 percent. While the parking lot pavement may be made of recycled materials as glass or plastic, the pavement is still capable of supporting the weight of an automobile while also producing hot air.
