Steorn's E-Orbo Launching - Torque without Back EMF - Is this possible?

[lightningbolt]

Hello Everyone,

 

The Irish company Steorn is launching their E-Orbo technology. The E-Orbo is basically a brushless DC pulse motor. However, they claim it does not experience back EMF, it's current/voltage does not change with speed (with a load or without a load), and it produces over 100% efficiency.

 

They have posted a video of a "talk" about their technology to Youtube. In the video they perform a set of experiments on the E-Orbo which seem to confirm their claims.

It is a simple, but very odd motor. It uses toroids as stators. That is very odd because toroids keep most of their field inside of themselves.

 

Is it possible to produce torque in an electric motor without back EMF?

I just read that Steorn's demo starts back up tomorrow at the Waterways center in Dublin.

Steorn just posted a video of another "talk" about their technology.

Now they are claiming a KE gain and an inductance gain!

What they need to do (assuming a net gain shown in the spin) is to take a Gauss meter and probe the magnets before and after usage.

 

My money is on the system siphoning some potential out of the permanent magnets, corrupting them over usage.

Hello Everyone ...

Hi, lightningbolt, and a belated welcome to hypography! :hihi:

 

You might find this 2.5 year old thread - 8075 - discussing a previous, failed public demonstration of Steorn’s Orbo, interesting. The general consensus after this was, I think, that the Orbo is either some sort of attempt at business fraud – that is, to get money from the foolish and unwary – or some sort of performance art (I unsure there was much consensus on the art part, rather it was mostly my speculation), or both. After a couple of years of apparent silence (see the 2007 to 2009 gap in the press releases at Steorn’s press release webpage) during which I though Steorn had disbanded, they appear to be again making the same claim, and proposing to test it with public demonstrations and discussion by people who physically or virtually attend them.

 

As they continue to offer an explanation of how the Orbo works (see How Orbo Works) that sounds to me like an attempt to confuse the reader with a very strange and wrong reference to Noether’s theorem, I’m remain convinced that whatever the intentions of the Orbo’s makers and promoters, it’s not a real energy source, but some sort of scam. The heart of their explanation appears to be that some sort of electric motor what have different efficiencies at different phases of its rotation can produce more energy that it consumes. As I understand mechanical efficiency, however, this just won’t work – having more efficiency in some phase of a motors rotation than another simply results in the motor have a net efficiency that’s roughly an average of the different efficiencies.

My money is on the system siphoning some potential out of the permanent magnets, corrupting them over usage.

The notion that permanent magnets can be used as a sort of energy storage device/fuel is in my experience pretty common among more sensible searchers for unusual alternative energy sources, but, as best I’ve been able to reason it, completely wrong and backward. As I explain in Motors "fueled" by changing the strength of magnets, reducing the magnetic field strength of a permanent magnet – which physically consists of rearranging its atoms so their magnetic fields are less aligned – doesn’t release energy, but consumes it! So, if one could somehow make a “magnet fueled” engine, it wouldn’t turn strong magnets into weak ones, but, counter-intuitively, weak ones into strong ones.

In the videos they prove the magnets do not degrade, the system does not experience CEMF, and the E-Orbo is overunity.

According to every credible scientific and engineering review of Steorn’s Orbo, including a jury selected by Steorn, to quote that jury’s announcement, “Steorn's attempts to demonstrate the claim have not shown the production of energy ...”. The wikipedia article “Steorn” has a summary and many links supporting this conclusion.

 

Almost certainly, Steorn is engaging in a commercial scam, soliciting money from people with money, but without adequate science educations, via a campaign of live and video demonstrations and endorsements by unethical people. I strongly recommend all people interested in science and engineering to not be fooled by this scam.

Anything overunity is a scam.
