They claim 95% efficiency through a capillary membrane to feed electrolyte to one side of a anode and cathode without direct contact with the electrolyte pool.

 

Here is the article that describes the process.

obsolete 50 years ago

I have not seen anyone else claim 98% Faraday and release the details to completely recreate it.

This Whole Forum shows Technologies  multiply decimals times better
industry rebuttal is 50 kw/ kg
Leaders are 33kw / kg
non public is sub 15kw/ kg
all faraday
So Meyers is x400% better than those again. 
There is alot known but in Short Stan Meyer is the best

I invite you to find out their Kw per Kg 
and than we can see on this scale where they fit in,

 Do not compare at all to 400% to 600% Stan Meyer Voltrolysis Process

Since we loop back electrons and make gas with EEC Electron Extraction and no dead short no heat or thermal run away and now electrolyze or contaminants
The fact such companies refuse to use Stans Technique of DBD barrier is a RED flag
