Earth’s resources are all we have right now when it comes to food, construction materials, a large part of the energy extracted, air and water. Yesterday, we’ve just depleted our consumption ratio for this year. What this means is that Earth can’t regenerate what we’ve consumed so far this year […]

So, being efficient means less money spent on them, and more market share for hydrogen. SOFCs (solid oxide fuel cell) are a type of hydrogen fuel cell that use solid (not liquid) electrolyte to do their job, while being much more efficient.

How can that be?

The most interesting thing about these plates is the fact that they can provide food for birds, squirrels or rodents.
