MIT engineers have developed a fast and sustainable method for producing hydrogen fuel using aluminum, saltwater, and coffee grounds.
When the aluminum in soda cans is exposed in its pure form and mixed with seawater, the solution bubbles up and naturally produces hydrogen -- a gas that can be subsequently used to power an engine or fuel cell without generating carbon emissions.
The researchers are developing a small reactor that could run on a marine vessel or underwater vehicle.
Team uses seawater to retrieve and reuse gallium indium using a solution of ions.
The ions in seawater act to shield the metal alloy from reacting with water.
But the ions have a similar effect on aluminum, building up a barrier that slows its reaction.
Researchers believe they have the essential ingredients to run a sustainable hydrogen reactor.
