Steorn Overunity Demonstration Completed
Today's demonstration summarized the findings of 1) no back EMF, 2) no component degradation (e.g. Gauss diminishing) to produce the effect, and 3) inductance gain (energy being harvested from somewhere). With this final demonstration, the technology is now being released to developers to prepare the technology for market.

Steorn did their "overunity demo" of their e-Orbo technology today at the Waterways building in Dublin, Ireland where they have had several copies of their electromagnetic devices on display since Dec. 15, minus a break through Christmas and New Years.
Steorn CEO, Sean McCarthy summarized the tests that have been done until now and then gave a final piece of evidence, live.
If their technology is what they say it is, it could provide a new, clean energy source that is affordable and available 24/7/365 and scalable to whatever size is needed, large or small, pulling inexhaustible energy from the environment.
One of the attributes he reviewed was the absence of back electromagnetic flux (BEMF) in the coils. This he illustrated by a videotaped presentation comparing their e-Orbo with a pulse motor of a more conventional arrangement, then showing the oscilloscope readings that show the absence of BEMF in the e-Orbo while BEMF exists as would be expected in the conventional pulse motor.
McCarthy also reviewed a test that had just been completed, which had spanned the past week (live on streaming camera three), in which the gauss (magnetic field strength) of all the magnets were measured before, then measured again at the end of a week to show that there had been no degradation in the magnets. This was to show that the energy manifesting in the system was not a function of components of the device giving up their energy and being degraded in the process.
Then, McCarthy showed a scope shot comparing the electrical input energy to the electrical output energy, showing a net gain in inductance or gain in energy (harvested from the environment somehow, in the tradition of Nikola Tesla). One curve represented the gain in output energy after each pulse, rising from left to right; and the other curve represented the sum of input energy during the same period. That curve was shown to be well below the output curve, hence yielding the conclusion of "overunity".

The demo had better views than this. I'll post a better one when I can grab it from the Steorn video channel.
If I understand correctly, the oscilloscope shot being shown live was of the motor as it was presently running, giving such a result live.
McCarthy said that the data they had recently collected showed 320% more electrical energy being produced compared to the electrical energy being input. That number does not take into consideration other factors such as bearing and air friction as well as heat. He said this data would be posted on their website for review. Apparently Steorn did not get around to doing a calorimetric test they had planned, to quantify the heat generation component of the system to include that number in the input:output calculation. McCarthy announced that they had extended their stay at the Waterways building and would be allowing people to make appointments to come in and measure these systems for themselves through February 26. Meanwhile, beginning in the first of February, Steorn will open the SKDB (Steorn Knowledge DataBase) initiative for educating licensing parties in the process for the beginning of their development process. The first week will be exclusive to those who have already been involved in the SKDB process and are licensing its development.
The presentation lasted about half an hour, with over 900 people watching live by the end of their webcast, and probably at least a hundred present at the Waterways building. McCarthy said that there have been around 2500 visitors so far at the Waterways building since they launched the demo on December 15th. The purpose of these demonstrations has been to interest development groups to get involved, under license, to develop the technology to its myriad of applications. McCarthy said Steorn has made the development license fees low to encourage more development, with the hopes that the more people who get involved in developing, the faster the technology will arrive in the marketplace in practical embodiments. The cost of a developing license is 419 Euros. McCarthy said that there have also been third party validations of their technology, some of which they will be allowed to post on their site. He said that some of those who do independent tests don't wish for their names to be made known publicly; which they honor. Though McCarthy hasn't mentioned it, the reason I use the "e-Orbo" designation is because the company allegedly also has an all-magnetic version of the electromagnetic phenomenon, which I would guess will be called "m-Orbo." It was in an interview with me right after they first announced their discovery in the Economist in Aug. 2006 that McCarthy said that their effect was an all-magnet motor. (Ref.) Apparently somewhere along the way in the process of exploring the various aspects of the phenomenon, they came up with an electromagnetic version; and after much debate, they decided that the electromagnetic version would be the one they would put forward at this time.
