This work is about a development of a vacuum solar water heater. To accomplish this, some measurements were made, such as flow, water temperature and room temperature, relative humidity, solar power density and wind speed. It first presents a brief explanation about the global situation in relation to the accelerated use of exhaustible energy sources which can result in a breakdown of these for future generations. From this, is proposed to analyze this solar water heater with vacuum tubes during the winter season in Brazil southeastern region, under different environmental conditions. From such ideas became possible to prove through the experimental part, calculations and graphical results that technology and the performance of this device are technical and economically viable, according to the life cycle of this. It was also found that the average monthly production in a maximum heat stroke situation was 193,33kWh and minimum isolation was 57,76kWh. This reveals that this instrument should start to be examined more closely by all, as a way to reduce the use of electricity, which will protect the environment without reducing the comfort of people

This paper discusses the influence of the design parameters in the operation and construction of an internal combustion engine. A theoretical analysis was developed using a standard crank-connecting rod-piston to verify the behavior of the stresses generated in the combustion and transformed into rotational energy of the crank shaft. Design parameters directly influence not only the final result of the characteristics of power and torque, but how the engine must be built to withstand different loads. The choice of parameters of a combustion engine is directly linked with the application of the engine and the final result expected of it function
