Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Notes on BH curves: The BH curve of magnetic material drastically changes from one extreme of an open magnetic loop (e.g., a rod) to the other extreme of a completely closed magnetic loop (e.g., toroid). For most non-PM magnetic materials, the BH curve is relatively flat (linear, not square) for completely open cores such as a rod, but the same material formed in a toroid could have a BH curve well over 90% square. For cores with high permeability, even the slightest air gap in two U shaped cores will most likely produce a flat BH curve, but when pressed *tightly* together to form a solid closed core could show a square curve. Only materials with extremely high coercivity such as PM's have a square BH curve even when the rod length to diameter ratio is low.

The same applies to *effective* permeability. For example, a Metglas material may have an effective permeability of 80000 in toroid shape (close magnetic loop), but may have an effective permeability of just 6 in the shape of a short rod.

Paul,

I cannot understand the rational that you are too busy to build a device as you describe that would essentially give you the rest of your life off
if you sold the prototype that ¨works¨

Ofcourse you must be too busy with your diode array as you say, however something does not add up to my thinking ?

Cheers

This is too funny. I hope legit people are taking note to all of the potshots.

Anyhow, the answer is simple. The mathematics for the magnetic research has shown it's most likely very difficult to overcome the losses. Diode research is a guarantee! The diode arrays are considered infinite efficiency since no voltage source is required.

All that's left is to come up with an inexpensive easy method of making semiconductor fabrication equipment that anyone could build to make their own diode array *chips* that could power their home and beyond. They could be the hero of the block by selling inexpensive chips to the neighbor.

Question on coating metal wire:

Someone was asking a good, but simple method of coating the MIG welding wire. The welding wire comes copper coated. After a bit of thought, using a spray can of paint would work, but it's a bit awkward in that the wire would have to be pre-cut and lined up for painting. It would be nicer to have a brush or sponge, and then simple bush/wipe a coating on the wire before cutting the wire off the spool. That way, the coated wire could be positioned inside and then cut to correct length. If the wire needs to be cut before hand, then it will need to be cut extra long because once the wire is positioned into place it needs to be cut to exact length.

In short, spray can method would waste some wire. So, what kind of liquid would work best in coating the MIG wire? Some sort of a varnish?  Or perhaps acrylic paint? Or a stain? Something that is found at a local hardware store is recommended.

Also, this method should be quick drying because the person needs to make hundreds of small MIG wires to form the core.

Thanks,
PL

Also I thought that oxidizing the copper would be a good idea, but that's probably a bad idea because even the slightest exposed steel would begin to oxidize.

So far the acrylic paint seems best. It dries within minutes. It's flexible and tough.
