How Many LPM Does Your Cell Make?

I get asked this fairly often from customers who are trying to do a due diligence and compare our products with the products of other vendors. Unfortunately, the answer is often not of value because of the fact that there is so much variation in the way HHO cells are tested, the equipment used, and also variation in the understanding of some of the vendors in our industry. This leads to misleading, if not outright lies about the capability of their cells. So after answering an email about this for the hundredth time, I decided to give a complete answer and put the answer in an article for all to see. Here is that letter:

Hi Louis,

Thank you.

The truth is, you can get almost any LPM from any cell. Many vendors state that their cells, which should produce about 1 LPM max under normal circumstances, get 7 LPM or even more. Those cells will do that, but it will be mostly steam because the cell is over driven. So actually the better statistic to compare is how much plate area there is in the cell. This compares the capability of the cell to produce HHO without overheating. For instance, I've driven my cells for medium engines up to 7 LPM. They'll do it for a while, before overheating. But I would never try to produce that much HHO from that cell. I'd use our biggest commercial cell, which has about 8 times the plate area if I needed that much HHO.

So, the LPM of the cell isn't isn't an important point unless you are trying to drive an engine larger than the cell was designed for. We size our cells so that they are the correct size for the engine they are are being used for. As long as you are using a cell that is able to efficiently produce the amount of HHO needed for your engine, then the cell is big enough. Using more HHO than this amount will start to reduce your gains, even if produced efficiently. We don't know why this is exactly. We just know by extensive trial and error that its true. See this article to see why: How Much HHO Should I Use?. So, if this cell is for your pickup truck, then you only need to know that you can get an efficient 15 amps worth of HHO from a cell. That's enough for about 1 LPM on a 12 volt system. That's the most you will need to get the best mileage gain on your pickup.

Also, LPM per amps is pretty much of a constant with dry cells. The only reason I say "pretty much" is that its only true if the cell is made correctly. Ours are. We have been doing this for 8 years and we have a $1,500 flow meter on our bench that has been calibrated for HHO specifically. We've tested the best cells on the market, and our own. We know what a cell can do. So I can tell you that we get 5 MMW (Milliliters per Minute per Watt). Only the best cells get that kind of efficiency. But most reputable cell makers are able to get this same efficiency. Some guys claim much higher MMW, but these are at best misleading and at worst false. When higher numbers are reported it is due to over-driving the cell as I described in the first paragraph above. When you are blowing steam through your cell, the "MMW" is inflated. But in this case the added "MMW" is steam. And steam is bad for your engine. Note, I said "steam", not "mist" or "fog", as the latter is good for your engine. But fully evaporated water (steam) is bad. So over-driven cells, will report high LPM and high MMW and will get worse results than a normally driven cell at much lower amps.

I know this isn't an exact answer to your question, but I hope it gives you a better understanding of how HHO works in your engine.
