The angular speed of plant leaf rotation was from 0.070–0.262 rad/s.

When studying the dependence of plant leaf rotation movements on the area of the plant leaf, it was found that at a 150 W light source, the angle of rotation increased as the area of the plant leaf increased. After applying a light source flux to a plant leaf and inducing a temperature change in the tissues of the plant leaf, the rotational movements of a freely hanging plant leaf about the suspension axis were studied. The operation of the biological heat engine in a plant leaf was proven by indirect experimental measurements. The values of biological heat engine in a plant leaf and the associated processes are minute. The paper presents experimental research on thermal energy conversion into mechanical kinetic energy of the flow in plant leaf stomata. There is a biological prototype of a heat engine in the leaf, where leaf stomata convert thermal energy into mechanical kinetic energy of the flow with a change in leaf temperature.

The shape of leaf stomata channels is much more sophisticated compared to gas flow transformation channels in energy production facilities. Leaf stomata perform a similar function in plant leaves. In the technical field, the potential energy of gas under pressure is converted into mechanical kinetic energy by means of special complex channels.
