Scientists have devised a strategy, based on the abundant carbon dioxide in the Martian atmosphere and the use of generators that produce electricity from temperature differences, to provide electricity to a base with human tenants on Mars and supply it with chemical compounds that will be useful There.
The research in which this strategy was conceived and its validity was verified is the work of a team led by Abhishek Soni, of the University of British Columbia in Canada.
It is possible to generate electricity using special materials and physical contact between two nearby points that have sufficiently different temperatures. In laboratory experiments with systems of this type, the research team determined that when the temperature difference between the two faces is at least 40 degrees Celsius, it is possible to energize machines that convert carbon dioxide into carbon monoxide, using as source of electricity generators based on the described principle of temperature differences.
In the case of a base on Mars, the difference between the temperature inside, which must be high enough to make that space habitable, and that outside, which, depending on the area and the weather, fluctuates between 20 degrees Celsius above zero and 153 below zero, it would allow the generation of the electricity necessary to power machinery with which carbon dioxide would be taken as a raw material and useful carbon-based products would be obtained, such as fuels and other chemical substances necessary for daily life to the Martian base
Since the chemical composition of Mars’ atmosphere is 95% carbon dioxide, the raw materials for these processes would be abundant and easily accessible.

The same technological approach, with some adaptations, could be used on Earth, particularly in geothermal plants. The difference between the temperature of the hot pipes connected underground and the lower surface temperature would be enough to power the chemical carbon dioxide conversion machinery.
Geothermal power plants generate electricity primarily using steam heated by natural heat deep underground in areas with some volcanic activity. The steam drives a turbine whose mechanical energy is used to power a generator to produce electricity.

Interview: Exploring Mars’ Future Power Solutions
Interviewer (Time.news Editor): Welcome to Time.news, and thank you for joining us today! We have with us Dr. Abhishek Soni from the University of British Columbia, who recently led a groundbreaking study on sustainable energy generation for future Mars bases. Dr. Soni, it’s an absolute pleasure to have you here.
Dr. Abhishek Soni: Thank you for the warm welcome! It’s a pleasure to be here, discussing such exciting developments in space exploration.
Interviewer: Let’s dive right in. Your research emphasizes leveraging the Martian atmosphere, specifically its abundant carbon dioxide, to create a sustainable power source. Can you tell us more about how this process works?
Dr. Soni: Absolutely! Our strategy involves harnessing the vast amounts of carbon dioxide on Mars and converting it into useful chemical compounds while simultaneously generating electricity from temperature differentials. Essentially, we can use generators that create electricity by exploiting the significant temperature differences we find on Mars. For instance, inside a base where humans would live, it’s essential to maintain a warmer, habitable environment, while outside temperatures can plummet to extremely low levels.
Interviewer: That’s fascinating! So, you’re saying that the extreme temperature swings on Mars can actually be beneficial for energy production?
Dr. Soni: Exactly! In our laboratory experiments, we found that if there’s a temperature difference of at least 40 degrees Celsius, we can generate enough energy to power machines that convert carbon dioxide into carbon monoxide. This reaction could serve multiple purposes, both for energy and necessary chemical supplies for the base.
Interviewer: It sounds like a game-changer for human habitation on Mars. How do you foresee this technology being implemented in the infrastructure of a Martian base?
Dr. Soni: The key will be creating a thermodynamic system that utilizes the environmental conditions on Mars. For a Mars base, humanity can rely on a setup where the internal environment stays warm enough for living conditions while the external environment provides a cold counterpart. This setup will not only help generate needed electricity but will also enable the production of resources, thereby supporting long-term human presence without heavy reliance on Earth.
Interviewer: This touches on a significant point—the sustainability of a potential Martian habitat. What are the longer-term implications of your findings?
Dr. Soni: Our work opens up the possibility of a self-sustaining Martian base. With the ability to harness local resources effectively, we can minimize reliance on resupply missions from Earth. This also allows for the exploration of other avenues—like processing local materials for building structures or making fuel, which are crucial for long-duration missions.
Interviewer: And what challenges do you anticipate in transitioning from lab experiments to a real Martian environment?
Dr. Soni: There are several challenges—first and foremost, scalability. We need to ensure that our systems can be expanded and maintained effectively on Mars. Then there’s the unpredictability of the Martian environment itself—dust storms, extreme temperatures, and radiation all pose risks to our technology. However, with thorough testing and innovative engineering, I believe we can tackle these hurdles.
Interviewer: That’s inspiring to hear, Dr. Soni! For those of us back on Earth, how can this research influence our understanding of energy sustainability in our own environment?
Dr. Soni: There’s definitely a parallel! The principles we are exploring for Mars can be applied to Earth, particularly in remote or off-grid areas. We can learn to optimize systems that utilize natural temperature variations—not just in space, but also to harness energy more efficiently in our own communities.
Interviewer: Wonderful insights! Before we conclude, what excites you most about the future of human exploration on Mars?
Dr. Soni: It’s the potential for discovery and innovation! Every step we take in researching and developing technologies for Mars could redefine how we view energy, resources, and even our capacity to adapt to new environments. I’m thrilled to see what humanity can achieve in the next couple of decades.
Interviewer: Thank you, Dr. Soni, for sharing your insights and the exciting developments in your research. We look forward to seeing how your work unfolds and the incredible possibilities for Mars exploration!
Dr. Soni: Thank you for having me! It was a pleasure discussing these ideas with you.
