Dry Ice to Power human colonies on Mars
Martian dry ice already exists close to its “sublimation point” – the temperature at which it turns directly from solid to gas. It therefore only takes a relatively small nudge for dry ice to change states. One of my aims is to propose harnessing the energy released by this change to power a heat engine – or even a whole colony.
Carbon dioxide plays a similar role on Mars to water on Earth. It is a widely available resource which undergoes cyclic phase changes under the natural Martian temperature variations.
Power stations on Mars will exploit all this frozen CO2 to harvest the energy from the sublimation phase change as dry-ice blocks evaporate, or to channel the chemical energy extracted from other carbon-based sources, such as methane gas.
Solar Panels or Solar Concentrator Parabolic dish would be used to harness this heat and direct towards the metal plates
The experiment I conducted below represents the Leidenfrost Phenomena with water.
