Another demonstration scheduled for December 15, 2009 had been promoted in communications and video streams. The device was displayed at Dublin ''Waterways Visitor Centre'', and three video streams were shown in the Internet (Links: [http://www.steorn.com/iframe-vid11.html] [http://www.steorn.com/iframe-vid12.html] [http://www.steorn.com/iframe-vid13.html]). The streams were interrupted several times. Also, cleaning personnel moved the demonstration engines out of sight to return them after completing cleaning operations.

The device was powered by a small rechargeable battery which was supposed to be recharged by operation and thus never discharge. Steorn even claimed the "Orbo 2009" model produced three times the energy it consumed. Surplus energy was said to be released as heat. The operating power was said to come from the magnets used (''Orbo is a technology that creates energy from magnetic interactions.'').<ref>[http://www.steorn.com/orbo/what/ What is Orbo?], Steorn Website, retrieved 9 March 2011</ref> The demonstration was scheduled to last six weeks, with a break between December 24 and 4. January 4, 2010. There are no instruments registering outputs or inputs of electrical current visible in the videos.

According to Steorn, giving a precise energy balance was not possible due to the "complexity" of the simple engine. Since it may not be excluded that the device was operated exclusively by the rechargable battery (1.2 Volt/10 Ah), the demonstration is not appropriate to prove Steorn's claims. Further information may be obtained only by an independent examination which e.g. monitored charging voltage and charging current of the battery (or of a large capacitor) over a longer period of time in order to establish the system's energy balance. According to Steorn, they were not prepared to consider the use of a capacitor as a buffer store instead of the rechargeable 10 Ah battery, since capacitors allegedly had „a delay in delivering current“.<ref>Comment by Steorn-CEO Sean McCarthy</ref> In fact, capacitors are able to provide current without any delay.
