An Irish company will today reveal controversial technology that allegedly defies basic laws of physics to produce free power.

Steorn, which is based in Dublin, claims to have discovered a method of creating clean, constant energy, which it claims could end the global fuel crisis.

Called Orbo technology, it is based on the interaction of magnetic fields and has yet to be conclusively proven.

Last year, Steorn placed an advertisement in the Economist magazine and challenged the world's scientists to test its claims.

The company picked 22 of the world's leading scientists from Europe and the US for the review, which started in January and is not expected to be completed before the end of the year.

Steorn is contractually obliged to publish whatever the scientists conclude in full.

Today the invention will go on public display for the first time with a live working demonstration to be streamed on the internet from 6pm tonight.

Steorn Chief Executive Sean McCarthy has said the demonstration will involve a 'very simplified version' of the technology and it will be open to the public from Thursday 5 July to Friday 13 July at the Kinetica Museum at Spitalfields Market in London.

Sceptics can view the device lifting a weight from four different camera angles online.

Mr McCarthy said the company had decided against using the technology to illuminate a light-bulb as the use of wires would attract further suspicion from a scientific community that has already dismissed the device.

The company stumbled upon the technology while working with wind turbines to power remote surveillance CCTV cameras for ATM.

Steorn claims the so-called free energy would be able to power anything from mobile phones to cars, providing a potential solution to the global energy crisis.

Mr McCarthy revealed that if the technology is validated in scientific tests, the company plans to licence it over the internet to any company who wants it for 'a very small fee'.
