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 of the 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 carbon dioxide chemical 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: Powering Mars – An Innovative Approach
Time.news Editor: Welcome, everyone, to today’s special interview where we delve into an exciting breakthrough in Martian exploration. Joining us is Dr. Abhishek Soni from the University of British Columbia, who leads a team that has developed a novel strategy to provide electricity and essential chemicals to a human base on Mars using the planet’s unique atmosphere. Dr. Soni, thank you for being here!
Dr. Abhishek Soni: Thank you for having me! I’m excited to discuss our research and its implications for future Mars missions.
Editor: Let’s jump right in. Your team’s strategy revolves around generating electricity from temperature differences and utilizing the abundant carbon dioxide in Mars’ atmosphere. Can you explain how this works?
Dr. Soni: Absolutely. On Mars, there’s a significant temperature gradient between the habitable interior of a base and the frigid exterior, which can fluctuate dramatically. Our approach involves (Peltier) generators that create electricity by exploiting this temperature difference. When two materials with different temperatures come into contact, we can harness that energy to power machines that convert carbon dioxide into usable carbon monoxide and other chemical compounds.
Editor: Fascinating! So, if I understand correctly, you’re using the extreme cold of Mars to your advantage?
Dr. Soni: Exactly! The temperatures outside the base can drop to around -150 degrees Celsius, while inside, we need to maintain a much warmer and habitable environment. This consistent temperature gradient—often over 40 degrees Celsius—creates a perfect scenario for energy generation.
Editor: How did you validate this approach during your research? What kind of experiments did you conduct?
Dr. Soni: Our team conducted extensive laboratory experiments using specialized materials that maintain efficient thermal contact. We created controlled environments to simulate Martian conditions, measuring how effectively we could generate electricity from the temperature differences. The results confirmed that we could indeed energize devices capable of converting carbon dioxide into other valuable substances.
Editor: It sounds like your work not only contributes to energy generation but also addresses the need for chemical compounds that could be crucial for sustaining life on Mars. What specific compounds are you aiming to produce?
Dr. Soni: We’re particularly focused on creating carbon monoxide, which can be used as a building block for fuels or other chemicals. By converting carbon dioxide into usable forms, we can help facilitate life-support systems, fuel systems, and even the potential production of food with the right processes.
Editor: That’s remarkable! How soon do you think we can realistically implement this technology on Mars?
Dr. Soni: While we’d need more research and testing, particularly in situ simulations, I believe this could be a part of future Mars missions in the next decade or so. As we plan for human colonization of Mars, solutions like ours will be fundamental in creating sustainable environments.
Editor: It’s exciting to think about a human presence on Mars becoming more of a reality! What challenges remain for your team?
Dr. Soni: The main challenges include scaling this technology to work efficiently in a Martian environment and ensuring reliability over long periods. Additionally, we must consider how to handle the maintenance of these systems in a remote environment where resources are limited.
Editor: Definitely challenges worth addressing. Lastly, what message do you have for the next generation of scientists and explorers looking to contribute to this field?
Dr. Soni: Never underestimate the power of innovation and collaboration. The challenges we face in space exploration are enormous, but with curiosity, determination, and teamwork, we can achieve incredible things. The future of Mars exploration depends on bright minds willing to think outside the box.
Editor: Thank you, Dr. Soni, for sharing your insights with us today. Your work offers remarkable promise for the future of Mars exploration, and I’m sure our readers will be inspired by your dedication.
Dr. Soni: Thank you! It’s been a pleasure discussing our work, and I hope it encourages further interest in space innovation.
