A new study from Boston University’s Center for Space Physics has determined that wind is an effective option for power generation on Mars! This is especially important to combat times of low solar activity such as we are seeing with the current dust storm, and to balance power needs when a piece of equipment may be in a limited sunlight environment for half the year. Additionally, radioisotope power (ie. nuclear) as powers the Curiosity rover would be counter-indicated in a polar region as it would impact any science experiments being conducted.
The original experiments for this paper were conducted in 2010. At the time it was determined that wind was a possible power source given climate conditions on the Red Planet, however there were concerns over the required size of the turbines given the state of technology at the time. Now with 8 more years of materials science and research behind us, the equipment that could be deployed for this purpose has sufficiently improved that it truly can be seen as a viable option. Another great step forward for Mars!
