We recently had a story about the non-event
that was to have been the public demonstration of the Orbo from an Irish company called Steorn. As it turned turned they had some technical difficulties with a machine that was supposed to provide free energy forever. Any claim of free energy is clearly to be taken with more than the usual dose of skepticism before being summarily dismissed.
Ryan, the chief gadget hound over at Engadget
managed to track down
Sean McCarthy the Chief Executive Obfuscater at Steorn and got an interview. Given the ease of getting patents granted these days, the fact that they have not attempted to directly patent this "technology" is not a good sign.
