Desired heat development for a light chain is analysed and studied from an outside perspective. The idea for modeling is cumulative energy balance, such that thermal energy could be borrowed from EM and material configurations. Kinetics due curvature (in slow motion) and bifurcations in nonlinear models are deduced as potential transformers into beneficial heat. The results were negative for the present LED-tube, and traditional light sources are preferred.

The purpose of this research is Design and construction of electric and hybrid car brake system. The production of electric cars goes back to the year 1900 AD, at that time, due to the problems that electric motors had on the one hand, and on the other hand, the discovery of oil and its abundant production, the production of these cars was not considered due to the dramatic progress of internal combustion engines. But with the emergence of world wars and conflicts over oil, this material gained more value and more attention was attracted to electric cars, and that was that since 1990 AD, the production of electric cars was more seriously considered. In electric cars, the power supply system includes an electric motor, controller, batteries, and its charger. The electric drive system of an electric car has the duty of converting the direct current produced by the battery into mechanical energy, which means all the parts that drive the direct current of the batteries. They are converted into the traction force and torque necessary for the wheels to move. Among the most important features of the electric car is the driving range, acceleration, speed, incline, loading, flexibility, charging time, and the high price of the batteries in most existing electric cars. In this research, the effect of installing a wind turbine to help the braking system and finally generate electrical energy to charge the batteries is investigated and by a moving damper, the direct wind flow is directed towards the turbine and causes the turbine and generator to move and finally It produces AC electricity and is converted into DC electricity by the inverter and used to charge the batteries. in other words, in this research, we come to the conclusion that installing a turbine, in addition to helping the braking system, helps to charge the car's battery. On the other hand, the solar panels used in the car also help to charge the car battery.
