Selfrunning HHO system with 400 Watts additional output

[Feynman]

That's because it's really difficult to get the resonant PWM working ... it's based on creating scalar waves, and requires frequency mixing in a toroid...  lots of places things can go wrong....

Why bother with the trouble though, especially if you can run generator COP=3 with just a standard series cell with a standard 1phase PWM unit or rectified AC mains 

Replicating Boyce TPU is another question entirely

True this is not anything fancy like a bob Boyce system. HHO  production tweaks can be done later but already the system has a COP 3 with basic DC control of the cell.

The logic here is just like a car engine ECU which controls the start sequence and sets the correct timing. While it can be done using gears and cogs its not very elegant and still has no control over engine speed so might as well do everything at the same time using a processor. Once you have proper control over gas production and the timing you got proper control over the engine.

Bolt, earlier you made mention of using RO water in your electrolyzer. Is there an advantage over using RO water v.s. distilled?

Thx,

Not really but some places getting access to distilled water is hard to find or very expensive. I'm in the UK and most pharmacies  either don't stock it or wont  sell more than a very small amount to make up their own medications for dispensing. I never seen it in super markets unlike the US or Caribbean which sell it everywhere.  So RO offers a very high purity of water in some cases better than badly produced distilled and its of course a lot cheaper.

You will find RO water leaves the cell running MUCH cleaner with far less by products of city water which contain dozens of trace metals and chlorine, lime etc. This creates a brew and leads to brown crap forming on the cells.  Never use those little bottles of spring mountain drinking water in most cases the water quality is MUCH worse than city water unless its been produced through an RO method and has no chlorine and re-mineralisation. This goes for drinking it too!

The standard 5 gallon water tanks used in much of the world -US, South Americas etc is in effect RO water and mostly high purity but make sure it hasn't been chlorinated and re-mineralised. 

For HV operation high purity is essential so that cell operates in high resistance DC but rather in inductance mode as a capacitor.  But even for  normal DC use it will make your cell last a long longer without frothing with crap. BTW good RO water is perfect for use as lead battery water.

Interesting, thanks for explaining the RO water. Your right, distilled water is available nearly everywhere in the states. The local (city) well water available to me is high in Radium. Before the city switched service to lake water deep breathing of hot shower steam was not recommended. Maybe it would be beneficial in an electrolyzer if demineralized ?
