CONTROVERSIAL technology which allegedly defies the laws of physics to create free power went on public display yesterday -- two years after a much-heralded demonstration ended in failure.
Irish company Steorn insisted the Orbo device was more robust and reliable as it welcomed potential investors to a Dublin viewing.
But chief executive Sean McCarthy admitted the device could still end up malfunctioning.
"The systems are up, they're running and I'm sure some of them will break -- it's a prototype," he said.
"We want people to understand where it is, but weigh that with what it could mean for us and what the opportunity is, not just for this little company in Dublin but for everybody."
Orbo technology harnesses magnetic effects to multiply energy. Its inventors claim it can be used to power anything from a mobile phone to a car.
Worldwide cynicism surrounding the product was heightened after the failure of its high profile London launch in July 2007.
Mr McCarthy said he could appreciate people's suspicions.
"It shouldn't be possible, it's something for nothing. But the bottom line is it does what it does and we're more focused on the impact of that and getting it into the real world than the scientific controversy around it."
The product is on show in Dublin's Waterways Visitor Centre at the Grand Canal Basin until January 31.
