It's hard to say what's happened to Steorn, Irish inventors of Orbo, once claimed to be an over-unity generator that broke the laws of physics but now barely worthy of couple of fuzzy paragraphs on the web site.
You can, however, enjoy their latest device - a water heater called Heptaheat. It heats water up really quickly, and in useful quantities: let nobody claim all those millions of euros were wasted.
Not good enough? Still longing for the glory days of public demonstrations of perspex wheels whizzing around powered only by enormous batteries? You're in luck. YouTube subscriber Eltimple has uploaded a set of videos apparently culled from behind the scenes of Steorn during those heady times. The best one by far is a Queen-flavoured musical extravaganza that stitches together a lot of before, during and after shots of the Orbo demo from the Dublin Waterways centre of just over two years ago.
But you may also enjoy this, where a mystery Irish voice encourages "Max" to "explain this fecking thing here, 'cos I'm feeling too fecking ill. Explain it there. Point yer fingers at it, man... wheels spinning, coils..."
There are other videos on that channel - have fun. Just don't ask me to start on Andrea Rossi, or we'll be here all week...
