It's pretty typical for tech startups that get their first big influx of investor cash to go on a spending spree buying all sorts of fancy equipment and toys that may or may not have any real value to the company. Then more often than not the money runs out, morale plummets, rounds of layoffs commence and eventually the company liquidates. As far as why investors fall for that stuff, people *want* to believe. I've encountered otherwise fairly intelligent people who fell for all that free energy BS, conspiracies about the 100mpg carburetors, etc. Makes for a good story to illustrate how "the man" is always beating up on the little guy and holding everyone down. There have been enough incidents in the past where people have accomplished things that most people thought were impossible. I think the laws of energy are well enough established that they can be taken for granted but I can see how less technical people might not think so. |

Hi there :) I've been an avid follower of Steorn for many years and I kind of assumed it was over but I was doing a bit of searching and I came across a Steorn patent that looks like it has only just emerged in the public domain. It looks almost exactly like the E-Orbo they demonstrated many years ago and claims to be an "Electric motor with no counter electromotive force" : https://patents.google.com/patent/US20110227440A1/en The patent expired at some point in the past due to a fee related issue but has recently had the expiration date extended to 2031 which I can only imagine is because someone has paid the fee and taken ownership of it! TL:DR - It claims to work by using a ferro-magnetic toroidal core made of Manganese and Zinc, (which I assume will have fast domain movement compared to a sintered Iron core), which is wrapped in a toroidal coil. The pair of rotor magnets have one North and one South facing outwards. They are attracted to the ferro-magnetic core which cause the core to become magnetic with a vertical pole orientation. They then apply voltage to the coil which turns the core from a vertical pole orientation to a horizontal orientation which releases the rotor magnets without any Counter Electromotive Force. To me this seems pretty fantastic, for obvious reasons, and i thought who better to debunk this than EEVblog, especially as he made a good video recently on back EMF. Although it doesn't specifically describe itself as an Over-unity device I am assuming that is what it is supposed be without specifically saying so, to not be rejected by the patent offices. Just thought some people might find it interesting. :) |

I recall pondering that for a bit, all those years ago, and concluded that there will be bEMF due to the unbalanced saturation of the core. Also, there's a tangential component to the core saturation; magnetic field is a vector after all, and effectively the core can handle sqrt(2) more flux if you do it from two directions rather than just one. Put another way, you need to make sure the core is very well saturated indeed (so that the hypotenuse of that triangle is dominated by the long side, the control bias, so the tangential element is forced to be small). Which still maybe isn't a perfect counterindication, but it also suggests losses will be high, on account of the higher bias requiring more copper losses. Anyway, the thing with being unbalanced is, some flux gets injected into the control winding. Think of it however you like: leakage escaping partway along the loop, or variable mu (effectively the lower mu near the magnet makes an equivalent magnetic circuit of an open 'C' with most of the control winding on it), etc. For a perfectly balanced control winding and core, external fields are ignored, but saturation is a nonlinear effect which breaks symmetry, thus allowing coupling from the outside. And as I recall, the mechanism they had was very well balanced (mechanically), so that it spun for a long time -- low friction. The classic overunity hack, using so little power -- and using mostly reactive power -- indeed the control winding is a huge inductor -- to bury the real power in the noise floor. If you can't show it making real motive power, don't waste my time! Manganese and zinc will be MnZn ferrite, of the formula (Zn,Mn)Fe2O4, crystallizing in the spinel family. Just any bog standard power ferrite. Tim |

They will just take bits of my video out of context and use it for propaganda or promotional purposes. The only winning move is not to play. |
