Design of a hybrid energy storage system
High-Level Project Summary
We propose to design a hybrid electronic and mechanical battery, composed of a wind energy generator that will use a turbine and the generated energy enters a mechanical storage system, which is based on the design of an experimental braking energy recovery device, which then enters an energy flow regulator when the springs are fully compressed.The advantages of our method over the traditional ones are that the materials will not suffer a considerable thermal expansion, the mechanical operation is more guaranteed than the chemical operation.

Detailed Project Description
Stored energy: 28 Watts (if 40 springs)
Source of energy: Wind
Rate at which stored energy can be used: approximately 70% due to incomplete charging of springs
Self-discharge rate: theoretical approx. 30% due to wear of metal elasticity, timing failures
Volume: approximately 0.016 m^3 each
Mass: 15 kg (plus lithium battery)
Operation temperature range: 100°C up to 600°C
Use of energy released on entry and atmospheric descent:None
Use of active materials (e.g., in the case of a battery, anode, cathode, separator, electrolyte materials): Solid-state LiAl-CO2 batteries
Whether a protective enclosure is required: Yes
Whether the system can tolerate the forces and vibrations due to launch, reentry, descent, and landing: Yes
Yes, a protective enclosure is required: Yes
Can the system be operated in any orientation: No
the spring alloy is inconel metal (a family of austenitic nickel-chromium based superalloys). Dynamo components must withstand a maximum temperature of 600°C as well as the magnets. The ideal diameter size of flat circular springs is 10cm, width 20mm, thickness 0.7mm. Graphene will be used in the movement transfer mechanisms due to its high resistance in durability and maximum temperature of 600°C.
Space Agency Data
From "Venus un planeta raro" and "Venus nunca es lo que parece", we were able to rescue relevant information about the planet Venus that could guide our project.
From "Automaton Rover For Extreme Environments" and "Broad Benefit Technologies: Energy", relevant material was extracted to mesh with the information previously obtained about the planet Venus, in itself guiding information about the battery.
"Tecnología de almacenamiento de energía elástica utilizando dispositivos de resorte en espiral y sus aplicaciones: una revisión", to better understand what elastic energy is and thus implement it in the mechanism of the energy storage system.
Hackathon Journey
Our space apps experience was interesting and very educational. What inspired us to choose our challenge was learning about new energy technologies, we learned about the characteristics of Venus and how to store energy mechanically, our approach was to innovate in the face of technologies that already had previously been presented. Our team has solved the challenges and setbacks with some methods such as brainstorming and looking for solutions in the documentation of the past.
