 McCarthy stated in a 2006 RTÉ radio interview, "What we have developed is a way to construct magnetic fields so that when you travel round the magnetic fields, starting and stopping at the same position, you have gained energy".In 2011, Steorn's website was updated to suggest that the Orbo is based on magnetic fields which vary over time.Barry Williams of the Australian Skeptics has pointed out that Steorn is "not the first company to claim they have suddenly discovered the miraculous property of magnetism that allows you to get free energy" while Martin Fleischmann says that it is not credible that positioning of magnetic fields could create energy.
