Started setting up a test HV water capacitor today. When complete, will test for charge holding capacity, and hopefully finally build enough voltage in it to point of destruction of dielectric (water). Will setup a small 555 breadboard circuit to slowly build charge automatically so I don't have to be in the immediate vicinity.

Yay!!!, AVR development kit arrived at last. Now to install the development software, test the board and create the injector drive circuit.
Got some of the machining of the test cell to fit the injector body today before the lathe drive belt broke. Not sure whether the 150 degree injector spray pattern cone will be suitable for a flat cap plate test. May have to see if I can get/make a replacement spray disc with a flat, narrow spray. Damn now I just found out the Lucas injectors have a narrow spray pattern.

Ordered AVR development kit today and will look at converting injector testing code to suit AVR instead, should also be able to utilise inbuilt PWM functions further down the track. Might be able to control both injector function and HV generation from one unit. Could also test things like TPS incorporation as well if things work out.

Was considering using Bowling & Grippo's injector testing setup but found someone had converted it already to use a PIC16F873 (may have to upgrade to later chip) and their assembler code to 'C' using the free Hi-Tech C compiler http://www.kolumbus.fi/juha.niinikoski/Injtest/Injtest.htm Will see if I can duplicate this guy's unit as he has C-source included. This should be enough to get the injector side of things running quickly, then it's just a matter of some other electronics to allow adjustment of HV and amps.

Test plan will probably go something like this: run injector X pulses at Y duty cycle and measure water output with no HV field active. Then switch on HV field and re-run test, measuring water output. If less water then presume that some has been converted. From there it's just a matter of trying different capacitor plate sizes, voltages, amperages etc. to find the point where 100% (or close to it) is converted from every pulse. Once have near 100% conversion, switch to capturing gas output and measure volume to compare with what is expected.

Received injector and connector plug today. Now to:

1) machine the test cell to accept the injector

2) prototype single injector driver electronics

3) prototype capacitor charge electronics

This injector has a rating of 4.65g/1000 pulses (4.65uL/pulse) so it's slightly under what Meyers was supplying with his. May be able to get around this by adjusting pulsing frequency. Will be using distilled water in a paint pressure pot to supply injector during test.

Ordered one Bosch 215cc/min injector and connector plug today, will try and alter test cell to accept injector for testing. Should be able to rig up an oscillator circuit to drive the injector in a test series.

Have returned to mini test cell work. Since each injection cycle uses around 7.4uL of water (according to Stan), we would need around 109 Joules of energy to disassociate the water charge completely. Really unsure what voltage is required because Stan mentioned many voltages along the way. The mini test cell is way too big to test such a small volume of water so I'll get a small high impedance injector unit (or set) to setup in front of a capacitive disassociation chamber which can be charged and held to different potentials. One thing for sure, the gap needs to be large enough that no sparks can jump the gap with the joules of energy required. That way when the water charge is injected into the gap (atomised), there will be a reduced chance of spark because of the slight increase in dielectric strength (atomised water or steam should be around 1.0079 instead of water round 80).

Unsure if a disassociation chamber can be regarded as a capacitor in it's own right, or it might need to be in parallel with a larger charged capacitor. If the latter, then it takes longer before the larger cap actually starts discharging so I'm hoping the injection cycle will be short enough not to discharge the feed cap at all, just apply the potential. Would prefer to not have to wind chokes etc. - this is a departure from Stan's approach which may or may not work, can always try chokes later if needed.

Will wait until I get a spare injector unit to play with before I look at disassociation chamber design.

Family issues have been absorbing much time during the last month so not much has progressed. 

Had some further thoughts on the supporting electronics for the 1 millilitre mini cell. Controlling the voltage supplied to the primary (and therefore the secondary output), seems to be a bit complicated, but I need this so I can 'tune' the cell supply for an empty (air) cell to the point just below where an arc forms between the electrodes. If I can hold the voltage just below that level, then there should be no worry about arcing through water in the cell. Can adjust the distance between the electrodes a small amount but doing so will also vary the volume so I may have to re-adjust calculations once the final volume is known. Primary thing is finding the right frequency and no-arc point that still has enough energy to disassociate the water.

Water in it's normal state at 80F has a dielectric constant of 80, boiling point 212F constant drops to 55.3, but at the point of vaporisation the dielectric constant drops right down to 1.00785, just above air at 1.0 (or dry air at 68F 1.000536)

Just in case I blow myself up or something, I'll lay out what I'm planning to do. Using my above calculations (which could be way out) i calculate if I can dissociate 1 ml of water per sec, I should get 1.86 lites of hydroxy in it's place. And using the above engine requirement calc, I should be able to run a 2000cc engine on that - hopefully.

What I plan on doing is to use a flip-flop driver capable of driving a couple of power transistors or FET's to run a centre tapped transformer primary, with a centre tapped secondary that feeds into a full wave 5 stage Cockcroft-Walton multiplier. Using a secondary feed of 1200VAC into the multiplier should get around 12KVDC producing 0.72 joules of energy per charge cycle (6 pulses?). If run at 100KHz, energy dumped at a 20KHz rate would amount to an output of 14.4KJoules of energy - more than needed to dissociate 1 ml of water per sec (I hope). That's probably the maximum, will start off with things wound back and work up gradually from there.

This HV DC output will be dumped into the miniature cell above after adjusting the chamber to a volume of 1 ml, and filled with water, Tap water works OK but leaves a hard black residue behind, so will use distilled water instead.

I don't know that I'll worry about the steam tests at this point because the amount of energy saved is minimal compared to the total required, and it's much more compact to store 1 ml of water rather than 1.8 litres of steam. But steam may come into play later as excess heat from the exhaust may be better spent distilling water to remove the contaminants before it gets to the cell.

According to research papers found, the energy requirement to dissociate one mole of water is 237.2 Kilojoules. Since 1 mole is 18ml, then it takes 13.18 Kilojoules per ml to do the job - still a lot of energy, although no-one said it cannot be pulsed during the second at higher energy potential.

Another bit of info, calculated orbital speed of a H2 electron is 6x10^16Hz. I seriously doubt I could build anything to resonate with that, especially driven by a 555 chip!!!

Initial Background (injector size disassociation chamber)

It seems we are going over and over the same ground. A lot of it has been covered by numerous experiments, some done by members of http://oupower.com/phpBB2 in 2004. You know the drill, get stainless tubes, wind chokes, build circuits, hope like hell for the magic breakthrough...been on this merry-go-round myself for quite a while now - time for something different, think outside the box!!!

Time to treat it all like a normal problem solving exercise - i.e. investigating parts of Meyer's puzzle one at a time in reverse order. I am presuming Stan's latest thoughts would be his current thinking before he was exterminated. A database of experimental results before building anything else for real is required. i.e. Successful disassociation data using different combinations of frequency, voltage, gaps, configurations etc., should help in development. mlpm=milliliters per min

Stan Meyer calculated water usage for his buggy at 44.4mlpm at 3000rpm (65mph). 

Did my own rough calcs to see if I could get anywhere near the same figures as Stan using normal H2 and O2 to water mole ratios. 

water_usage_calcs

Wonder how close that is to usage of others that have actually managed to get a vehicle/motor to run completely on hydroxy?

Further...if Stan fully believed a full set of injectors was the better way to go to actually get a vehicle running properly on hydroxy, then an injector sized splitter cell should still be able to do the job BUT supply gas along a supply line, not as an injector unit - either to standard H2 injectors or manifold (may need more than one but it may be possible to drive one constantly to do the job). As long as Stans injector was not copied, then the injector patents would not be compromised. 

It seems to me at the moment it would be far easier to completely disassociate a minute amount of water at a time (as in an injector) than try and disassociate the same volume from within a larger container of water. As long as the gases can be stabilized into the component parts before being transported along supply lines, it may work OK. May have to look into LED/Laser/Ultraviolet ionization and electron extraction to accomplish same. May work using either water or steam as the supply fuel to the splitter cell (or whatever it ends up being called).

Now to get the time needed to get stuck into these experiments and start the data gathering exercise...

TEST CELL

Currently setting up a miniature flat electrode cell, using two 1/4" s/s bolts with hex heads machined round to 10mm dia., fitted with 'O' rings for sealing. Both electrodes are adjustable so the gap can be varied from 0-5mm, thereby altering the chamber volume. Am aiming for a volume something around Stanley's injector chamber volume (guessing). Also, the volume should be small enough that if an arc should develop, the result will not be catastrophic (for me). I'm sure Meyer started off with small experiments until he had a better understanding of the forces involved, and then just kept improving from there.

To power this miniature cell, I'm building an adjustable coil driver circuit to pulse a standard oil-filled ignition coil NOTE: 5th July 2007 - coil didn't work at all, changing to transformer based HV driver instead. If there ever is any success with this cell, may be able to scale it back to a ignition coil later - time will tell.

Oscillator circuit is powered by a regulated 12VDC supply from an SLA battery to ensure stable output. Driver stage power is a variable, regulated, benchtop power supply of 0-15VDC, 20A max. This will allow the input voltage to the transformer to be varied from 0VDC to 12VDC thereby adjusting the resulting HV voltage. From there it should be easy to determine approximate breakdown voltages/frequencies required for different volumes.

Unfortunately most experimenters are concentrating on the original Meyers demo cell, which was just that, a small demo cell to get a patent (Meyer said so). The cell on the original buggy was huge... I am of the opinion that Stanley abandoned his original cell and went for the injector solution in the end as it showed more promise of being "the answer" to getting motorists off petroleum. Much easier to continually disassociate small quantities at a time when and where it's needed, at the cylinder - no storage or delivery problems, minimal flashback problems, minor conversion compared to a large cell conversion.
