I wanted Thane to write the rules.  No disrespect intended as I realize Thane has made sacrifices, just looking for that someone to set the world on a new path.

We all wanted Thane to write the rule. The problem is the "game" has gotten too big for just "someone" to write the rules. It will have to be "some group" and that group will have to be appear to be outside the "game" to re-write the rules. Something like an active independent group of replication builders.

But as for the tech, it is nothing mysterious. See Hop toads work and even my post of 2541 page 255 pre dates Mr T's last coil setup... 27 watts out for a cost of 19 watts. This on a very non optimized set up.

Hey I_ron is there any chance of you posting a link to 2541 page 255 ? Curiosity always gets the toad. ?

27 Watts for 19 Watts (70.3 % cop) is actually a pretty good electrical transfer (transmission) from an electrical motor (with its inherent loss) coupled to a generator (with its inherent loss). Using a conventional motor and generator to transfer electrical energy is notoriously inefficient, and off the shelf systems rarely achieve greater than 60 % total system cop.

Any increase, and / or broadening of the cop over a wider output load range is a good thing.

My observation of this "acceleration" phenomena with different core materials shows that high voltages (high impedance coils) are not essential to optimise the output, though they may be appropriate for particular and possibly even general applications.

I found it is better if the minimum amount of ferro-core material is used. The opposite direction to that which Thane's research has taken.

Just enough core material to significantly raise the Q factor of the inductor, but without significantly raising the inherent magnetic drag of the core. This means using a GREATER RATIO OF COPPER MASS TO IRON MASS to achieve the best inductive characteristics of the coils.

A higher voltage output (high impedance coil) will cause acceleration at lower RPM, but it will not necessarily deliver greater electrical energy "out" of the system (power output:VxI) into a resistive load (at any given RPM) compared to low impedance coils with high Q to reluctance ratio cores.

The ratio of coil inductance to coil resistance plays a more important role than the actual coil impedance or inductance.

The higher the ratio the better. However, air cored coils do not exhibit the same peculiar
phenomenon

Cheers all. keep on keepin on..

Yes hop, you see I have studied your work, lol

Now the coil test does not take into account the 200 plus watts of the driver, just the additional cost of generating that 27 watts. This is a cop of 1.42, incidentally and compares, as you say, very favorably with some of my usual coil test where the efficiency did/does range from 20% to 80%. I don't think Mr T took any notice of this post and came on his result by himself... I just was pointing it out as an 'irony' 

Still the rest of what you say is most correct and is the way forward for those continuing this quest.

Always a pleasure talking with you HT

Oh, sorry about the lack of a link, it took me 10 minutes to get to page 255 and I never thought to make a link... the new setup is really a pain to navigate

@gyulasun
thanks for the link.

@I_ron
oops, I made the mistake of reading your previous post too quickly and I transposed the order and significance of 27 and 19 respectively.

Cheers and kneedeep
