We don’t often cover semi-trailer trucks around here (actually, I don’t think we ever have), but when we see something cool we’ll bring it to you nonetheless. Walmart recently debuted an awesome-looking futuristic truck prototype during the Mid-America Trucking Show in Kentucky. The truck you see in the picture above still runs on diesel, though has the ability to run on electric power when needed. “Although the prototype currently runs on diesel, its turbine is fuel neutral and can run on compressed or liquid natural gas, biofuels or other fuels,” Walmart explained.
