Late last week, Sweden’s Scania revealed a world-first hybrid semi-truck covered in solar panels. Because of its self-produced energy, the unique prototype has the potential to reduce both operational costs and CO2 emissions of heavy transport.  The hybrid truck’s trailer is covered in 100 square metres of solar panels that are plugged into an electrical system carried on board. It is being deployed in a research project to examine how much solar energy such a configuration can generate, and how much it is possible to lower CO2 emissions through the use of the attached photovoltaic panels. As it swooshes silently down…
