Steorn's perpetual motion engine (reported here yesterday) has apparently melted beyond repair. According to CEO Sean McCarthy:
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.
They may have cheated thermodynamics, but they're still victims of Murphy!
