The claim is “14 times more hydrogen” not 14 times more efficient................
The article states "14 times more hydrogen compared with standard electrolysis techniques."
So what standard electrolysis techniques (source of hydrogen, power rate, electrode area, energy consumption) are being compared? Does the invention produce 14 times more hydrogen than standard electrolysis techniques using the same amount of energy?
“The electrical output of the electrolysis with sound waves was about 14 times greater than electrolysis without them, for a given input voltage.
Same input voltage, 14 times more hydrogen.....how much more efficient is it really?
