Global Nominee
Spring Energy Storage System in Vênus
High-Level Project Summary
through the strong winds found on the surface of venus, we developed a system that will use wind energy to compress springs, which when released, will produce mechanical energy that will be transformed into electrical energy through the alternators connected to the springs, thus producing energy so that the rover can walk on venus. Our project solves the challenge because it is capable of storing energy captured in the atmosphere and has a system of springs to transform this energy into electrical energy for the rover. our project is relevant because by using the spring system, we ended up avoiding different problems that other conventional ways of storing energy would suffer.

Detailed Project Description
Initially our project obtains electrical energy through the conversion of mechanical energy to electrical energy using springs and alternators that are initially charged by a set of propellers that capture wind energy from the air. After the energy is captured by the propellers, the movement of the propellers is passed to a gear that turns a rope connected to a box with the alternators (at this moment the box works only to compress) which will rise and compress the springs.
Once the springs are compressed, a sensor, powered by a carbon battery, will detect this situation and push a lock on the gear, preventing the springs from stretching, so energy will be trapped in the system, to release energy, the sensor unlocks the gear so the springs stretch and the elastic potential energy is passed to the alternators that transform this energy into electrical energy and then the current regulator will regulate the current sent to the system. The benefit of this system is that even isolated it is able to charge itself again after the energy inside the system runs out, and also the system presents less common problems of other energy methods such as the fragility of solar panels or the oxidation of a battery of lithium, and finally it also presents fewer problems than those that have electronic resources mostly such as power overload.
We intend to find a new method of energy storage that allows longer trips to planets with extreme conditions and that need more stable methods of energy storage.
We do not use any tool of this type for the development of the project.

Hackathon Journey
it was very unusual, we found it very difficult, we had never done a challenge of this level.
We learn more about how Venus works, we delve into the types of energy and their transformations.
We were intrigued to have the opportunity to solve a higher level problem never solved before. Initially, we got together in person to discuss the possibilities of solving the challenge, we came to a choice, the next day we decided to work around our choice.
We use mentors to solve our doubts, we try to keep the maximum focus and explore various possibilities and at first not give up on the first mistake.
The Submarino Estrelas group would like to preferentially thank our mentors Renato Sanchez, Ted Leandro and Michel Marchi for helping and instructing us on our path.
