STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

[freeorbo]

Hi folks, what do you think about this?
Searching for publications about Steorn and possible info on pm-orbo and e-orbo this showed up:

Steorn and The Holy Grail click here

If anyone has red it, please post any relevant info data/tests etc  Does it also include ss-orbo developments?
Thanks
Mike


Ps: As a side note,  an interesting coincidence how close the publication day of the book and the starting day of this thread, announcement of e-orbo upcoming events/demos etc.

You can look inside the table of contents. There's a whole chapter on the steorn forum (which if you've never been its a hornets nest). Its not clear if this guy had inside access or has just compiled a history from across the web but it definitely seems like a good read ( from the first few pages ).

It sounds like he knew they were going to do a demo but not of what.

Also, re: ss-orbo, steorn themselves only started working on it in 2010.

Video does not show any measurements but speed is impressive. Note that there is no arrangement to cancel bemf.

The most important question is -- how is he measuring the input and the output power? Before answering this the shown vid has no value whatsoever.

Looks like the world has moved on to the solid state lol
I'm still experimenting with spinning stuff. Its in primitive stage as you can see, nothing fixed or finalized, just trying things out. This is my second attempt, although titled ver 0.1, because the last one was made with high expectations and hopes but did not even spin (was with built in generator). This one spins at max 200 RPM with approx 2W consumption. Nothing has been optimized here, as you can see from the scope shot there is a lot of cemf (orange trace is voltage across the coils and purple is the current)

I'm using a simple circuit, I found some useful components in an old PC power supply, like fast power transistors and fast schottky diodes.

Next step is to add two more coils and remove the cemf. Will update soon.

Changed the PS to a brand new 12V maintenance free battery. Surprisingly, the cemf was reduced to almost nil just by changing the battery. I don't understand this, need to do some tests on this magical situation.

Made new arrangement to mount the 4 coils. For testing I removed all but one coil. Set a convenient air gap and some 100/200 ohm resistors in series at the base of power transistor. Took some readings, each time shorting one resistor to increase the current. Plots and excel sheet of measurement data are attached below.

A very important thing to notice is that at a certain current/power level the RPM shoots up. There is a non-linearity there. Any more current will not increase the RPM significantly. This is the sweet spot !

I will post more data soon for 2/3/4 coils configs.
