Acowlytes! I stand before you a stunned and humbled man. I wouldn’t have thought it possible, but on visiting the Steorn website this morning I was presented with incontrovertible proof that their Orbo engine is about to revolutionize the world! Never before have I seen evidence of an extraordinary claim laid out so compellingly, or been swayed by a concept so utterly mind-blowing!!!

HAHAHAHAHAHAHA! Hands up who believed me for even a second?

Nope. No hands there.

The images above are from Steorn’s much hyped video ‘Proving Overunity’, today posted on their site for all to see. The audience in the bottom snap is watching in awe disbelief as Steorn CEO Sean McCarthy trots out exactly the same old guff that has already been up on the Steorn site for ages. This is the sum total of the PROOF that Steorn promised the world, that their machine would be shown creating more energy than it consumes.

Needless to say both myself and the folks above were comprehensively underwhelmed. We watched as Mr McCarthy, in finest waffling form, yakked on and on about the Orbo motor’s wondrous abilities as he poked periodically at gauges and meters. As in the other ‘explanatory’ videos on the Steorn site, he seems particularly hung up on making us aware that Orbo has no ‘back EMF’ – really, it does not matter one whit about such electrical engineering-speak if the machine is able to show a 200% increase in energy output as has been claimed. The tedious ‘technical’ talk is there to cover up the fact that what Steorn actually needs to demonstrate is mind-bogglingly simple. In fact, it is as simple as 1+1=2. I can outline it to you in a paragraph:

Imagine feeding the Orbo 1 watt of power. According to McCarthy, the miraculous technology behind Orbo can take that 1 watt and use it to generate 2 watts. Are you with me? Now, this is all that needs to be done to show a miracle: take the output of the Orbo and divert 1 watt of that power back into the Orbo’s input. Now the motor is powering itself and you have 1 spare watt1 of energy with which to do anything you damn well please. Let us, for example, hook up some LEDs to this extra power (a single LED typically uses way less than what we have at our disposal). What we now have is the Orbo motor, running itself and powering some lights with no other external source of power! THIS would be a truly astonishing and unequivocal verification of Steorn’s claims. No-one could argue with such a direct experiment. In his circumlocutious descriptions of the Orbo technology McCarthy himself has said that such a feat is feasible.2

That’s all that has to be demonstrated. But really, they can’t show anything like that because it can’t be done. Instead, in the manner of every perpetual motion swindler throughout history, Mr McCarthy3 is obliged to obfuscate and complicate with abstruse methodology and meandering reasoning.4

So after all that, let’s see how Steorn is doing on the Tetherd Cow Ahead Interest-O-Meter…


Enough said. We won’t be mentioning Steorn again here on Tetherd Cow unless they do something a lot less monotonous.




  1. Actually, if you believe Sean McCarthy, 1 watt is small potatoes – there is NO LIMIT to how much extra power you can get… []
  2. “We’re recharging batteries and you will see… we’ll be lighting lights and all that kinda stuff later on… []
  3. Actually, Maybe Sean McCarthy is a personified demonstration of overunity – he certainly seems to run perpetually on excess amounts of his own self-generated hot air. []
  4. You will have seen this behaviour in just about every snake-oil salesman we’ve had cause to examine here on The Cow. The ShooTAG! scammers do the very same thing []
