Dear All,
Graham Gunderson does have two technical videos placed on YouTube. One is 10 minutes long while the other is 20 minutes long. These were filmed just prior to the convention and apparently deal with additional technical details. Now that his password to this forum site is working again he says that he will release these films to the public. Originally he wanted to make them private because of the information they contained, however he would have to provide YouTube with an email address for each person that wanted to look at them. I don't know specifically what they are about.
But, don't expect anything soon. Graham says that he will release these films on this forum after he writes up a suitable introduction with background information.
The real reason his response is going to be slow is that he has contracted for some very lucrative side work that pays many times more than his day job wage. So his evenings are now spent making the big bucks to help pay the tax man off. He is rebuilding a piece of aircraft test instrumentation from the 50's that is irreplaceable.
On the technical front Graham talked about another mode of operation that he discovered while getting ready for the convention. This mode was just screaming with at least 2K VAR of reactive energy oscillating in his tank circuit. He talked about how the current through the choke changed. It was in this mode that a slight rotation at an arms' distance of a couple of PM's would greatly impact the operation of the circuit. He didn't explore this mode for very long since the convention was on the horizon, but he wants to get back to it and is certain that the present H-Bridge is not up to the challenge.
Graham is not happy with the performance of his present H-Bridge. I suspect that it has stability issues and was responsible for toasting the last set of MOSFETS. It is like he wants to disown that sub-circuit, despite all the hours spent during its construction. That was his old love. His new love is some new fly-back controller chip that has provisions for the regulation of up to three output voltages and somehow "looks through the transformer" to get feedback information. I don't know how this is done, nor do I know what the chip is at the moment. Unfortunately there is no commercial transformer that will fill the design bill. He has to design and hand wind at least four (4) of these to make things work. Thus the need for the transformer winder machine. Hopefully the machine that is available can make transformers large enough the do the job - To be determined. The Jovil machine can only wind torrids up to 6mm in diameter with three conductors of #30 AWG wire.
Graham has been following the posts on the forums, but didn't have access to OUR until recently. He says he has already gone round and round in the past with fruitless discussions of "gate leakage" and "skew parameters", which are important issues but subjects that he doesn't wish to defend and comment on again.
He really thinks that his presentation was a global flop. I agree, that being as it may, he thought that if this technology had been available 5 years ago many people would be all over it, that hasn't happened. I suspect that most all the real builders have passed on, become burnt out, lost the dream, or have moved into assisted living facilities. Anyway he feels a real sense of disappointment in the reception of these new ideas, perhaps he got his first royalty check for the DVD and didn't make enough to buy both his sons a value meal at MacDonald's. So he feels no urgent need to move ahead with developments since in his mind hardly anybody cares. He appreciates the efforts and comments of those on this forum, but the six or so interested people are far less that what he expected.
I told him about the 577 views of some of the photos on overunity.com. We both wondered why so many lookers and so few do-ers these days. Then again this is not an easy circuit to replicate compared to a Bedini School Girl Motor.
Obviously nobody has approached him to discuss an outright purchase of the technology or to offer grant funding.
He also believes that there are probably 50 ways that this approach could be utilized for OU, such that a patent on this particular method is not all that valuable (thus no buyers). There may well be several people looking at these documents with the express intent of developing a patentable variation in other countries. Well more power to them. Perhaps in the past there was more collaboration than what we see now. I'm sure the 2009 changes to the US patent laws haven’t helped.
Graham seems ambivalent about the Open Source issue. He has the impression that people would expect complete and detailed plans with an up to date parts source list, and then complain about unresolved construction issues and forgotten notes. He says that nobody would follow the plans anyway. Why spend the hours compiling all this data for a setup that he doesn't like for a very small group of unimpressed viewers. He says that the real talent, if they see any merit in what has been done to date, will run with this and make the necessary improvements as they go.
Otherwise he is going to continue to move at his own pace and take advantage of the extra income while it is available.
Make no mistake he is still very interested in this phenomenon and is continuing the exploration of the fundamental physics, which he has no idea about.
Meanwhile the rest of us, especially me, are still playing catchup.

PS: Does anybody want me to re-post the photos of the H-Bridge and coil winder that I posted on overunity.com while I was having access issues?
PS: Graham did say that the intent of the choke was to make the inductor act like a current source. He didn't know what a "Swinging Choke" was (Apparently little exposure to Ham Radio). He said that he custom built the one he has to reduce the inductance so that it would store more energy and not saturate as fast.
