Abstract
As the demand of electrical energy in the country increases, an increase in generated power is needed. However, the Filipinos could not harvest most of the potential energy the country possesses. This roused the concept of energy scavenging from the environment to become an enviable method of powering electrical and electronic devices. The project described the design of sand heat recovery through Peltier plates, utilizing Seebeck effect for power generation. The objectives of the study were to design and develop a project that will recover the heat of the sand and convert it into usable energy using Peltier plates; determine the amount of voltage that the project can generate; and evaluate the efficiency and effectiveness of the project. Voltage is generated when there is a temperature difference between the sand and the heat sink. The researchers used the developmental approach in designing the heat sink and the heat absorber to harvest the heat of the sand effectively. The researchers found out that as long as there is a difference in temperature between the opposite sides of the module, there is a corresponding generated voltage depending on the weather condition since the source of heat will come from the environment. Much lower generated voltage during rainy days is expected. Therefore, the higher the temperature difference, the higher this the expected efficiency of the project.
