Go to Mars, that’s fine. Better go there. But with all this, it will take energy. Electricity in particular. And also on Earth, the question now arises how to produce it. As on Earth, both solar and nuclear seem to want to pull the blanket on. Which of the two will emerge victorious? The researchers have their idea.
Experts say it over and over again, in the context And generating renewable electricity is meaningless. Down to earth anyway. But the debate now has suddenly taken to an unexpected level. By exporting to Mars. While most engineers who worked on the question have validated the nuclear option as the best alternative, Today (the United States) revealed that solar energy could produce all the electricity that future Mars colonists need. For an extended mission and even for permanent installation on the Red Planet.that we live, we oppose
L ‘, it presents itself with a few of the same flaws as those we know on Earth. The electricity produced must be stored in this way if it is to be used at night. And on Mars, From dust sometimes obscures the sky, covering everything with a red veil. remember that from NASA It was broken by one of these storms in 2019.
Difficult to assess energy needs
But the UCSD researchers didn’t want to stop there. In order to compare the two solutions, they chose a systematic approach. looking at a 480 days, travel time about 420 days incl. Because they do not know exactly what the energy needs for such a task are, the Build a mathematical model to explore different scenarios. Scenarios including for example temperature and pressure control needs for fertilizer production for Mars, to produce methane that will provide the propellant for Intended for return to Earth or for the production of bioplastics.
They compared these needs to nuclear energy production capabilities, photovoltaic production systems, along with three storage options. Simple batteries, produced by During the night of Mars or during the famous dust storms.Directly by photoelectrochemical cells or hydrogen production . Hydrogen which can then, some on Earth imagine, be used to supply it
Solar energy can be the most interesting
As a result, on nearly half of the surface of Mars – especially in the tropics – solar energy has finally been presented as a more interesting solution than nuclear power. If and only if solar energy production is combined with a hydrogen electrolysis system.
The issue of efficiency, but above all, the weight of the solar panels. For a landing site nearFor example, researchers estimate that the total weight of the onboard solar panels – plus the hydrogen storage system – would be about 8.3 tons – for a rocket carrying a 100-ton payload. -, compared to 9.5 tons. Ton for Kilopower reactor system. Perhaps enough to consider carrying emergency boards. Which would not be possible for the nuclear system. However, the researchers point out that their work is only relevant if we take into account the recently developed flexible solar panels. Lighter because it works without structures in Or even glass supports like those traditionally seen on From our good old land.
