Environmentally safe, non-toxic, and clean - The Salt Water Fuel Cell Baja Runner is the larger brother of the award winning Salt Water Fuel Cell Car. It is more than twice the size but with only 29 assembly parts! This huge wheeled vehicle is designed and intended to facilitate transport via salt water fuel technology. The Salt Water Fuel Cell Baja Runner Kit is OWI's fifth generation and newest addition to its growing line of Salt Water Fuel Cell kits. How does this eco-friendly technology work? After activating the magnesium fuel cell module with a saltwater mixture, the chemical reaction generates electricity using salt water as an electrolyte to power the on-board motor. The magnesium metal sheet can operate the Salt Water Fuel Cell Baja Runner for roughly 5-7 hours of continuous fun.
