Brazilian Electrical Engineering Student Creates Solar-Powered Oven That Reaches 400 °C

Student From Instituto Mauá de Tecnologia Develops Electric Stove to Escape the Crisis. The Engineer Developed a Solar-Powered Stove That Can Reach 400 ºC.

Focusing on developing a project that can help those in need, the student named Leonardo Barsotti created a solar-powered stove. With the rise in gas cylinder prices, the idea can contribute to the lives of many people. Barsotti is a student at the Instituto Mauá de Tecnologia and came up with the idea to develop the electric stove for his Final Year Project (TCC).

Solar-Powered Stove Uses Photovoltaic Module

The student shares that he has always been interested in solar energy and that he always studied in schools that allowed him to see places where there was little access to electricity. Thus, the idea of building an electric stove that can be powered by solar energy was something spontaneous.

The project of the solar-powered stove aims to meet current demands in Brazil, serving the country’s food sector. The project works by using a photovoltaic module, which is installed within a circuit with a transformer.

The voltage from the solar panel passes through this transformer, and within this circuit, it will operate at 9 volts, passing through a power circuit responsible for sending a signal that is transformed into temperature.

The electric stove is accompanied by a temperature sensor that will regulate this heat. If the student’s project is used in automatic mode, the user can set the desired temperature; in manual mode, there is the option to choose between low, medium, or high temperatures.

Solar-Powered Stove Can Reach 200ºC in Just 5 Minutes

The stove has the capacity to generate up to 400ºC, and with just 5 minutes of operation, it can reach 200ºC. The idea is for the student’s electric stove to have a battery bank, which can be charged in the sun on a good day, thus allowing it to continue functioning if the day is cloudy, because it will be charged. However, without this component, it is still possible to use the solar-powered stove just by placing it in the sun.

With the current situation in Brazil, many people are facing financial difficulties and are returning to using firewood to cook or heat their food. The student’s project would make it easier for this part of the population to access this basic item.

The student also highlights that there are improvements to be made before the product goes to market, but that it is possible and part of his plans to expand this project.

Researchers from UFRN Create Stove Powered by Sunlight

Researchers from the Federal University of Rio Grande do Norte (UFRN) have developed a stove that uses sunlight to generate heat. This stove, which utilizes the renewable, free source abundant in the country, is a great option to navigate through the crisis and overcome moments of adversity.

In addition to not using cooking gas, the stove was developed using discarded or low-cost materials, such as mirrors and scrap. According to the inventors, only R$ 150 was spent to produce this prototype.

Furthermore, although cooking gas combustion is considered clean, that is, without emitting any pollutants, there are options that are even more sustainable, such as the one developed by UFRN researchers, as it not only harnesses clean energy but also uses materials that might not be recycled.

Thus, the initiative further contributes to the environment, making the solar-powered stove a great option if it reaches the market.
