Salt Water Fuel Cell Robot

Build a sleek, modern and adorable walking robot powered by salt water and magnesium - no batteries required!

Discover how a metal-air electrochemical cell stores and discharges electrical energy using a simple saltwater solution. Explore the science of electricity, currents, and electic potential. An innovative pump mechanism prvides a steady drip of salt water onto the magnesium plates and the robot walks for us to one hour on just one drop of salt water! The "fuel" bottle is easy to clean, refill, and reuse for hours of exploration.

A full-color 28 page manual includes step-by-step assemby instructions and delves into how this green technology offers a truly safe, non-toxic, long-lasting, and renewable source of energy.
