On Mars, electric vehicles are the only option.

Since 1997, electric vehicles have toured the Martian terrain.

As Space.com points out:

“NASA’s tiny Sojourner rover hit the red dirt in 1997, followed by the golf-cart-size twins Spirit and Opportunity in 2004. And last August, the 1-ton Curiosity rover dropped in to determine whether Mars could ever have supported microbial life.”

Since there’s no possible way to refuel on Mars, these electric vehicles have relied on various trick systems to remain operational.  These tricks include solar arrays on Sojourner, Spirit and Opportunity and a radioisotope (plutonium-238) thermoelectric generator on Curiousity.

All but Sojourner rely on lithium-ion batteries for juice or an extra kick when needed.  Sojourner used a nonrechargeable lithium-thionyl chloride battery for backup.

So, yeah, we could say that electric vehicles have been operational (and dominating) on Mars long before they became readily available here.  EV market share on Mars? 100%.

    So combining today’s stories, what percentage of people on Mars are considering buying an electric vehicle in the next 12 months. 😉

  2. kunnar says:

    same is true for moon, 100% market share for electric vehicles there as well

    I not quite sure a plutonium 238 vehicle can be seen as an electric even if it is a motor that indeed drives the wheels.

    On another side of it I imagine what it would take to have a combustion engine on the Moon or Mars. You would need to bring the Oxygen along and provide an efficient cooling system. On the other side, it would be easy to have a quiet engine since there is no air to transmit the noise. You would be left with the vibrations though. The exhaust to the vacuum would be very efficient, especially without the need for muffler.
