The possibility of generating electrical energy from the thermal expansion of liquid and solid matter is considered. Setting up the device using solely the liquid thermal expansion and contraction phenomena requires high-volume vessels that shouldbe able to sustain very high pressures, which is expensive and difficult to realize. In the case of using the thermal expansion and contraction of only solid material, the problems will include their small coefficients of thermal expansion compared to liquids, the impossibility of using the volume expansion, and very slow displacement velocity, which is difficult to accelerate.If both liquid and solid materials are used in combination, one can find reliable and cost-effective compromise variants of the device for different magnitudes of power.
The principle of the working of the device, designed using both solid and liquid materials, is presented. The small but powerful displacement will be transformed into high pressure and this pressure is transformed into liquid flow through the transducer. The latter transforms the flow into a circular motion and transfers this to the generator, which produces the electricity.
The new type of device, which uses a renewable energy source, requires high pressure vessels. The pressure in the vessel (5) can be reduced by increasing its diameter: if the radius r1input increases twice, the pressure P1decreases four times. On the other hand, decreasing the pressure leads to the increased volume of the working liquid, which is related to energy losses.
As the processes of thermal expansion and contraction are very slow, transforming them into fast enough linear or circular motion requires modern and very accurate techniques. It is important to find the optimal and compromise values of multiple operating parameters, such as the length of the steel rod, the pressures in the vessel (5) and in the low-pressure cylinder, the diameters of the vessels, the volume of working liquid, the flow rate, and the speed of angular velocity of the shaft of the generator in creating the new type of renewable energy source. However, such a complex task can be simplified noticeably if we develop the high-pressure and high-volume cylinders: the power of the device is in direct proportion to the pressure, which can be sustained by the system. So, by increasing the pressures in the vessel (5) and cylinder (7) by 10 times, the same device can generate 1000 kW energy per hour in our case.
