Hi Mart,
Thanks for the video. I currently have two pico hydraulic turbines in my garden.
I’m trying to improve them, so it’s always very interesting to see videos on the subject.
These are two Turgo-type pico turbines, currently producing 350W each (but I’m trying to improve them with my printer).
A Coanda grid system captures water upstream of my property.
The water is then channeled through two 160mm diameter pipes to the turbines (one pipe per turbine, which splits into four injectors).
These turbines are housed in an underground inspection chamber (for discretion), and the water is discharged into the small stream downstream, at the edge of the property.
That was a good video. I hadn’t ever seen coils done like that, in fact, I didnt know that is how they were done.
The next video was pcb motors which is essetially the windings replaced with pcb traces… but about 45s in, it has a short clip of how they do windings commercially.
