In augustus 2006 kwam het Ierse bdrijf Steorn met een opzienbarende claim:

Our Claim

Orbo produces free, clean and constant energy - that is our claim. By free we mean that the energy produced is done so without recourse to external source. By clean we mean that during operation the technology produces no emissions. By constant we mean that with the exception of mechanical failure the technology will continue to operate indefinitely.

Een soort perpetuum mobile dus, en derhalve strijdig met fundamentele natuurwetten, vandaag echter is het zover:

Steorn demonstrates free energy technology in public forum

Demonstration at Kinetica Museum, London, UK is world's first outing for Steorn's Orbo technology and will be streamed live around the world
