Or... more correctly... because NO PROOF has ever been given that the claims of excess energy production from an Orbo...  of any kind.... are true.

All that's been forthcoming from Steorn is more delays, less definite claims, and a water heater using a huge thermal mass to heat a small quantity of water. Where is the self-running magnet motor they pretended to show at Kinetica all those years ago? Haven't they been able to fix their bearings YET? Where is the self-battery-charger Orbo that they pretended to exhibit at Waterways? They showed us the scopeshots that they said "proved" overunity performance.... and I fully duplicated that performance, producing the negatively accumulating energy integral just as they did. I even showed something they did NOT show: usable power generated by a generator coil, not shorted, on the device. And I also showed that these things do NOT prove overunity for their device.
The "solid state" orbo systems that they allegedly produced and distributed... incomplete.... to their SKDB never worked as they claimed, or at least nobody of their SKDB membership ever reported attaining any kind of self-powered system using that device. And ALL of Steorn's demos that actually turned, or flashed lights, or made scope traces... they all used batteries or mains power. As does their HEPHA-HEAT current kludge.

In short, this Orbo thread died because Steorn had nothing then, and has nothing now, that would honestly qualify as an "overunity" device. Their pulse motor of the third kind (core effect) -- the  original Orbo -- is very interesting in its own right and will teach anyone who builds it a lot about pulse motors, the core effect, variable reluctance systems and so forth. Free energy? Look elsewhere, it's not to be found in Steorn's stories.

I can't send him this link because I don't have a YouTube account to post comments.

P.S.
An expensive scope and gear but no soldering iron ?
