    Today’s Progress
    https://youtu.be/kMVrNmKWc8o

    By the way, I have another light board just like this that I used to do all my original measurements. I just gave it to Greyland when I left the big machine at his shop. So it isn’t like I will “suddenly” be putting meters on the machine to measure things.

    When you look at the extra input vs output it is pretty good. For the bifilar it works out at 10/8 which is 125%.
    For the ordinary coil it's 10/11 which is 90%. So if you had 30 bifilar coils you'd get 300 watts out for 240 watts
    in plus the 270 iding which is total input 410 watts. 300/410 which is 73% overall efficiency.

    How are you comparing efficiency? Efficiency kind of implies conversion or change. Are you comparing what goes into the motor to what comes out of the coil to establish “efficiency”? If so, I like where you are going.

    I've been thinking about the debunked video. The fellow gets exactly the same .035 efficiency from the bifilar coil and the mono coil.
    There is an effect which can come in to play, see link

    My Prius is a motor generator. The other day I was sure it was going to throw a rod out the side.
    Go to 8 min on this video and hear the racket.

    I had a look at this today. Very interesting.

    Good prototype, looks very solid and well done

    I've just seen your previous message and I see your point about the magic 5. I'm just trying to describe what my own experience has shown me.

    Turion, You've got a decent amount of money but you don't waste it do you? Well, treat your motor generator the same way, best practice will pay off in the long run.
    My main interest has been in small wind projects where axial flux is appropriate in so far as you get high efficiency at moderate speed. For me an efficiency of somewhere in the mid 70's isn't too shabby so what you're talking about is in a whole different ball park!

    Quantum,
    I’m paying attention. The main reason I wanted a better working prototype was as a test bed for many of these things. Speed can also take me right past the “neutral zone” on my coils and you should see the motor take a five when THAT happens.

    Before you totally poo poo my ideas you've got to realise that the same rules are going to apply to your generators. Excess speed will cost you.

Many variables still exists for rotor magnet placement and spacing. If one set of magnets is to close to the other set they may conflict.

    Can you post a picture?
    I give more details, of how I have the configuration, six magnets of 2 inches in diameter, by three quarters of an inch, installed in the rotor, these same generating magnets I use as repellants, the magnet that is in the stator that serves to avoid drag , it has a measurement, 20 mm x 20 mm x 10 mm, it is square, as you can see there is a big difference between these magnets, so I think that is why there was some heat in the small magnet, for now it is what I have as a rotor, I have to configure a new rotor and with symmetrical magnets.

    Having the proper configuration, you would no longer have that heating, it would be insignificant

    Quantum,
    I understand what you are saying, and building something with as little loss as possible is always the goal. But I am looking at this from a system perspective rather than just a generator perspective. If I put in X watts and only get out 5X instead of 6X because I am using air cooling, I can live with that until something better comes along. I’ve even thought about holes all the way through the core that allow generated by the rotor to pass through the core and cool it. Because this machine does not have to abide by all the restrictions placed on normal machines to achieve “efficiency” you can come at problems from a different direction sometimes. It
