Scarecrow's HHO test measurements 20080301

[RHEAD100]

I may be way out in left field some place, BUT; that seems to me to be enough to heat a house in the winter. And far more efficent than an electric furnace. Some body tell me if I am right or wrong, please

[SmartScarecrow]

well, I appreciate the thought, but its not even enough to run my 2.5 HP Briggs small engine at normal RPM ...

the device I am showing puts out 3 LPM when loafing, 5 LPM when running at full power and 6 LPM when I run it at about the highest output practical ... this is enough to idle most small engines but not enough to run them at full operating speed ...

I am building a bigger/better one now ... very similar design based on a combination of my own and results obtained by Sid Young ...

Wow thats a lot if HHO in a small amount of time.

[SmartScarecrow]

I have since tweaked the device a bit and am now producing 5 LPM with efficiencies of about 4.8 to 5.2 milliters per minute per watt of energy used. When I run it hard, without any concern for efficiency, it can produce 8 LPM.

I am now aquiring the componenets required to assemble a new one based on this protype that should be able to produce 15 LPM with even higher efficiencies.

One step at a time learning from each step along the way.

are you using distilled water?

[SmartScarecrow]

in the electrolyzer, yes, distilled water with just a touch of KOH.

I dont need very many amps with my setup because I am running at a medium voltage. In these tests, I was running 85v @ about 17a. So I used about 50 grams of KOH in about 6 liters of distilled water.

now the bucket of water I am using to take my output measures is of course, just nasty old tap water ... but tap water creates too much gunk to use in the electrolyzer ...

[coolcat12121]

ok i was about to say thats alot of distilled water

[PeteDog444]

Great job, keep up the good work!!!

i'm doing the same thing just trying somethings see what i can do my production about doubled just from changing from them light covers to stainless steel plates 22 gauge

[copleygsxr]

Looks like steam to me

[SmartScarecrow]

some modest amount of water vapor is to be expected ... you can see the water vapor condensing on the sides of the plastic jug ... but with this setup, there is no steam created ... fluid temperature at start of tests was about 61 deg F ... four hours later after 30 performance test runs, temperature of fluid had increased to only 66 deg F ... I have made my share of water heaters ... this aint one of them ...

[stronglungs]

may i ask why so many volts and i don't see how it's sitting in water it looks like no water at all yea i'm new to all this i'm just trying some things i have seen on here and learning as i go i'm gonna try more plates how many does it take to make that much gas 200-300 lpm

[SmartScarecrow]

My setup is purly experimental. I have no intention of trying to adapt to automotive installation. The device I am testing puts out 4LPM without any problems. Might do 8LPM if I really push it hard. So would take 40-50 like mine to power a car.

The voltage required is related to plate configuration. You want a voltage of 2-2.5v per "plate gap" to get compromise between production and efficiency. I have 31 gaps, so at 85v amd at about 2.8v per gap.

still pretty good production if u ask me. - hey, - i hope u had hot water in that bucket!

[SmartScarecrow]

well, we started with hot water ... but it was cold outside !!! did not stay hot very long.

On production, you aint seen nuthin' yet. Turns out 4LPM is EASY with this device. I think when I wire it up for 12v and hit it with BIG AMPS (80-100a) we may see 6-8LPM.

But my overall efficiency is rather poor at 3.33mmw. I may have to address this issue before I put this design to bed and start working on the next one.

[mielectric1]

lookin good ssc, but don't your hand get cold? hehehe

[SmartScarecrow]

It was a bit over freezing the day my son and I were taking these test measures. I started with a bucket of HOT water but by the time we were finishing up four hours later it was tepid to say the least. But I collected a lot of perofrmance data on the device with a total of 30 test runs with/without pump, at 36v, 65v and 85v.
