Global Nominee

The electric storage and generation on the planet Venus.

High-Level Project Summary

Our team, developed a system that uses the high rates of wind on the surface of Venus, to generate energy needed to power the rover, a wind generator that is connected to a transformer that is also connected to a lead-acid battery, a simple type of battery to storage the energy that is generated, since there aren't electronics in earth that are capable to stay in good quality on high temperatures, we are also going to use a cooler that is similar to the one in the ParkerSolarProbe. It solves the problem because all of the pieces are made of a list of materials that can resist the high pressure, temperature and the corrosion. It's important because it innovates in a simple energy matrix.

Detailed Project Description

The project we did is a simple energy matrix, involving a wind generator, a transformer, a cooler and a battery. The wind generator is formed by 10 wind blades, that are fully covered in graphene so it can resist the HP, HT and corrosion from the atmosphere, with a length of 2 meters of diameter; the transformer is a toroidal one so it stays simple and effective, since it has a low rate of energy loss and a low tension variation; the cooler is based on pressurized water so in that case it won't evaporate in a system called rankine cycle, so it can keep the whole project in a temperature around 30 to 50 °C; and the battery is a Lead-Acid, and the reason is because it's a simple battery, it can be recharged and it has a long duration. The materials we are going to use to cover our whole project is a shield made of a

carbon carbon alloy so it can resist the HT, a rhenium pernitride layer so it can resist the HP, the graphene for the generator so it can resist the impacts.

This whole thing works in a simple way, the high winds from the surface will power the wind generator that will send the energy to the transformer who sends it to the battery that powers the whole electronics from the rover.

Since the materials are similar to the ones that are normally used for space travel it won't be a problem to get them, and it's a low and easy maintenance project so if something goes wrong there it can be fixed.

The main objective for this energy matrix is that we may be starting to explore more and more of the planets in our solar system, so if it works according to the plan, we can start exploring similar planets like venus.

HP = High Pressure

HT= High temperature

Space Agency Data

We used 2 main websites from Nasa and one PDF that talks about batteries in Venus.

The first site we used was Venus Resources, from the main Nasa website, on this one we got some datas about temperature, pressure, some names from missions to venus that we looked for to see why they failed so we wouldn't do the same and etc...

The second site was Energy Storage Technologies for Future Planetary Science Missions, also from the main Nasa Website, and on this one we got some data about energy storage and how this would be useful.

The third thing that we used was a PDF called Batteries from venus operations, where we got a lot of inspiration on what type of battery would be nice to use, and how a battery works on such high parameters.

Hackathon Journey

For me and for my team we really liked being on a hackathon, since for most of the group it was our first time being on a hackathon, and it was beyond the expectations that we had, it was way more challenging and intriguing since we had to search a lot to develop the project; we learned so much about venus like the huge rate of winds, the corrosive atmosphere and more.

For us the main reason why we picked this particular challenge was that it was a fun and "simple" project compared to the other options there, and another reason was that the majority of the group are engineers with the emphasis on electric and automation/control, so the theme was perfect for our group.

Our first approach was to search for the better way to generate energy in venus since it's not a simple task, after that we divided our group so each of us got a role, 2 of us went to search materials for the high pressure and high temperature, and the other 2 went to search about how would be storage that energy.

We solve everything by communicating with each other and sharing opinions about all the topics we were searching for, so even though we sometimes didn't have the answer we would still search more and talk a lot with each other.
