Mr. G cell Project Page 5

7/14/08. 2006 Mazda MPV. 6 Mr. G coils, 2 sets of three in pipe. Ugly. Many recognize what it is and ask driver for info.

Waste spark on briggs 5 h.p. ignited gas, shredding the tops on 6 cells. The cells had been hooked to power for about an hour before ignition.
Note. Waste spark, to my knowledge, only occurs on some one cylinder engines. It occurs when the coil receives a charge from the flywheel as it passes near the end of the exhaust valve cycle. In other words, it fires the plug on each engine revolution, producing a spark each revolution, when a spark is needed only every other revolution.

The beginning of the coil cell. Stainless 2 1/4"x15" (.020-.030" thick), cut in 1", 3" from the end, then cut down middle. I drill holes for mounting extensions now (for #10 stainless screw and nut), and sand metal well. Picture shows 1" ends section beginning to roll.
I experimented with many coil designs, lengths, widths, and tapers. I THINK this works well because MAYBE where the current comes in the wide section acts like a storage capacitor, and the vortex induction in the rest of the coil complements this. Longer ones did not work as well. I tried shaping like a vortex galaxy, but it was a failure, don't waste your time. I stumbled upon this particular design by accident. It was a leftover piece of metal, and rather than waste it, I cut and coiled it. Sometimes it pays to just keep on trying.
7/8/08. This design is unique. as such, it is presented here for your personal use. License to manufacture or resale controlled by the following:

Here is a view of the coil.
I cut a deep notch in a 5/8 bolt, slid the 1" wide end in, start turning with pliers. At about 1 turn, insert about 2 layers of cardboard to keep coil from becoming too tight. If your coils are consistent, you can slip them together for assembly with a little coaxing. Then I use weed eater line where necessary to keep metal from touching. You can use zip ties on the outside if they are too loose.
The coils in the photo at the bottom have not yet had the weed eater line spacers installed, in case you are looking at them and thinking "That will not work!"
Here you can see how the part of the metal on the outside at the top is raised and is not active in production, this is the 12 sq. in. referred to later. But that raised area does seem to contribute something to the overall result.

A group of Mr. G cells nearly ready to install in various applications.
I love these things, can you tell?
You may notice the numbers on the cells. Some cells perform slightly better than others, due to the slight variables in construction. The number is the maximum operating watts (without vacuum) after warming up. Two should be run in series, to eliminate heat. I try to match two with similar ratings for installation. I install these in sets of two, as in 2-4-6, etc.
Date- 6/26/08. Do not use this type lid, as it is not vacuum tight. Better not to use this type container, but it is better than nothing.
