This is a pretty interesting application for solar in trucking. Other truck makers are starting to explore how to use solar panels to power the auxiliary systems of trucks with oil pump, used to run air conditioning, heating or TVs for drivers that sleep overnight in the cabs. And just to note, most truck makers are not looking to power a truck with solar panels — the propulsion energy needs of a truck are too high and the real estate on the roof is too low.
3. Liquid nitrogen: Now this one's cool (awful pun intended). A British company called Dearman has developed an engine that uses liquid nitrogen, which is chilled to negative 320 degrees Fahrenheit. The chilled nitrogen cools the trailer but also expands as it warms, driving a piston and generating power. So the liquid nitrogen both powers the trailer and provides the cooling.
