Over time, the methods of capturing solar energy have obviously evolved (and perhaps become a bit less dramatic) but there are ...

Hydrogen Detection and Control
How Lead-Acid Batteries Release Hydrogen Lead-acid batteries produce hydrogen and oxygen gas when they are being charged. These gasses are produced by the electrolysis of water from the aqueous solution of sulfuric acid. A Vented Lead-Acid (VLA) battery cell, sometimes referred to as a “flooded” or “wet” cell, is open to the atmosphere through a flame-arresting vent, and ...
