i wish i could do it for you, but i don't know how to convert gas into watts or i would..

if you produce 5 liters of hydroxy using additives, the power in watts would be different than if you produced 5 liters of hydroxy with no additives. so even though you produce the same amount of gas with additives that someone else produces without without additives, the power in watts the gas makes would be different even though both are 5 liters.

how to turn gas into watts i don't know, so therefor we do not  know how to calculate the efficiency yet..

Here are the pictures of my cell. Today I built and ran it on the pulsed alternator design with tap water and no additives. My results are 1.3 liters/min at 14.6 amps and  26.2 volts. all numbers taken at the cell. I put two 12 volt batteries in series to produce 24 volts and the output was far less.

hrmmm,, i would think you should be producing around 600 cc's a min, just over half an liter...

what is your cell setup again? you say you used no additiveS? if what you say is true then it is a record breaker! we must investigate!

could you give more detailes about your cell setup? also, are you sure you measured the voltage across the cell, and the amps going to the cell? also is that a 12 volt alternator?

Flush your cell out for a good time and re run the test, dude you are on to something... keep flushing water threw your cell and get back to us on the new measurments when you think your cell is clean of additives. Also, what is your gap size?

if possible, include gas output with and without the water pump so we can tell if its doing anything.

Very interesting design, I LIKE IT

Space is at a premium in my car. I would like to recreate your cell. Can you give more details on it. Is it 316L, 304 , or what. What size tubing, and what length. And I like the recirculation pump, No cells choking. Nice fresh ideas. Pretty cool man      Can't  wait for more details

I re measured the gap between the tubes. The ID of the larger tube is .900" and the OD of the smaller tube is .870". That gives me a diff of .030" and div by two gives me a gap of .015" around the tube. With the water pump not running it abruptly stops producing gas. Iv been reading and building cells behind the scene for about 9 months but none of the plate designs or any that require the bubbles to leave on there Owen come close to the production of gas. I didn’t want to share the design but decided it would take many to break the oil bank NOT JUST ONE. I flushed the system three times while I set up the pulsed alternator and used the oscilloscope to tune it to your directions. Tomorrow I will run the numbers again. I was shocked how cool the system stayed with 4vdc per cell. More info tomorrow.

Got a question is the inner tube perferrated and blocked off so the water can flow through the gap between the inner and outer tubes or am I missing something in your design from the way it looks the water will flow straight through the inner tube

Hydrocars I forgot to add that it is a 60-amp 12-volt ford alternator. I did have to change the stator wiring to match your drawings. The voltage and amperage were taken at the cell. The only problem is to get it primed at the first start up I have to give the rotor a few volts to get it going. Spike hold for a bit this is a prototype I made to see if it would work. It is made of 304 that I had laying around and the ends are plumbing parts that I machined to fit, tight tolerance due to the gap being so small. Now that it has proven itself I am going to put 4 tubes inside them selves to improve performance and drop the volts down. My only problem with putting a design out is those greedy people who want to make greed money from other people’s work. But if it for your own playing I will help all I can. Hydro have you series cells to 2 volts with the alternator set up yet or will the amps drop so low that it wont produce much. Target there is a cork in each end about 3" down with epoxy on top of that (If you don’t put the epoxy the corks will get pushed over the exit holes) which forces the water to go through four small holes that I drilled in end to allow the water to enter and the exit holes are a little bigger on the other end. Time for bed will post more tomorrow.
