&lt;br /&gt;
The engines allow a great deal of portability. Smaller engines can be used for small vehicles traversing the surface or excavation, while larger engines can be used to generate electricity during night or emergencies. Waste heat from these engines can be recycled into heating the vehicles and habitats or into nearby industrial processes, such as warming ice into water.&amp;lt;ref name=&amp;quot;:0&amp;quot; /&amp;gt;&lt;br /&gt;
