Maybe this is a stupid question but is there any value in trying to put solar panels on the roofs of trucks to offset fuel costs?
Solar panels are (new) around $0.75 / Watt and less than that used. Maybe you could fit 9 or so on the top which, depending on what panels you use, could be about a 1kW or so in sunlight. Maybe it's too much of a stretch to ask for a modified engine but heating the driver cabin or even providing some type of heating or cooling to the container might help offset costs.
