Presenting the Eco-Tron "Oxy-Trekker" long-range botany hauler.
As everyone knows, the Eco-Tron were a peaceful race of botanists until their world was destroyed. Using their vast knowledge, they genetically engineered plants that produce one hundred times the normal amount of oxygen, which they use as a source of power. Now the formerly pacifist scientists are space nomads trying to survive on a dangerous new planet. Every Eco-Tron vehicle has a plant under glass that it uses as a fuel source, and this one is no exception.
