This is exciting! The idea that dry ice occurs naturally on Mars and can be used to power very simple but efficient power stations is exactly what the colonists will need!

This takes me back to high school Physics class. We were shown a series of films that demonstrated various physical principles. For demonstrations involving conservation of momentum, they often made use of "hockey pucks" made of dry ice. These were placed on a table that had a sheet metal top. The evaporation of the dry ice created a gas buffer between the puck and the sheet metal, allowing the pucks virtually frictionless movement.
