I think your answer can be found int he company's press release of 5 July:
"Steorn announcement: Kinetica Demonstration
Further to Steorn’s announcement yesterday (5th July) regarding the technical difficulties experienced during the installation of its “Orbo” technology at the Kinentica Museum in London, Steorn has decided to postpone the demonstration until further notice.
Sean McCarthy CEO stated that “technical problems arose during the installation of the demonstration unit in the display case on Wednesday evening. These problems were primarily due to excessive heat from the lighting in the main display area. Attempts to replace those parts affected by the heat led to further failures and as a result we have to postpone the public demonstration until a future date.”
He continued that “we apologise for the inconvenience caused to all the people who had made arrangements to visit the demonstration or were planning on viewing the demonstration online.”
Over the next few weeks the company will explore alternative dates for the public demonstration."
They keep forgetting to turn out the lights when putting their demonstrations together - lol.
