PRESENTATION OUTLINE
Introduction
We made a saltwater robot because we want to make the people understand how different it would be using saltwater power instead of oil and gas. This is good for the planet because it saves a lot of oil and you can always reuse it, and there would be less pollution in the air. It can save electricity.

Burn!
Right now we are burning coal, oil and wood for energy to power trains and other vehicles. We also burn oil for cars to get powered. But solar powered cars are powered by electricity. And right now we are wasting resources to just power vehicles.

How does saltwater power vehicles, etc?
How it works. Saltwater is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. These ions are what carry electricity through water.

How it works part 2
The aluminum, saltwater and carbon form a battery. A battery with these parts is called an aluminum-air battery. That's because it produces electricity from a chemical reaction between the aluminum and oxygen from the air. The aluminum combines with the oxygen to make aluminum oxide. The reaction releases energy in the form of electricity.
