REVOLUTIONARY TECHNOLOGY
Steorn’s technology produces free, clean and constant energy. This provides a significant range of benefits, from the convenience of never having to refuel your car or recharge your mobile phone, to a genuine solution to the need for zero emission energy production.
The Energy Project
In 2003 Steorn undertook a project to develop more efficient micro generators. Early into this project the company developed certain generator configurations that appeared to be over 100% efficient. Further investigation and development has led to the company’s current technology, a technology that produces free energy. The technology is patent pending.

Our Technology and the Laws of Physics
Steorn’s technology produces free, clean and constant energy. This provides a significant range of benefits, from the convenience of never having to refuel your car or recharge your mobile phone, to a genuine solution to the need for zero emission energy production. It also provides a secure supply of energy, since the components of the technology are readily available.
The technology is in a constant state of development. The company has focused for the past three years on increasing power output and the development of test systems that allow detailed analysis to be performed.
Steorn’s technology appears to violate the ‘Principle of the Conservation of Energy’, considered by many to be the most fundamental principle in our current understanding of the universe. This principle is stated simply as ‘energy can neither be created nor destroyed, it can only change form’.
Steorn is making three claims for its technology:
<ol style="margin-left: 2em; padding-bottom: 1em"><li>The technology has a coefficient of performance greater than 100%.</li><li>The operation of the technology (i.e. the creation of energy) is not derived from the degradation of its component parts.</li><li>There is no identifiable environmental source of the energy (as might be witnessed by a cooling of ambient air temperature).
The sum of these claims is that our technology creates free energy.
This represents a significant challenge to our current understanding of the universe and clearly such claims require independent validation from credible third parties. During 2005 Steorn embarked on a process of independent validation and approached a wide selection of academic institutions. The vast majority of these institutions refused to even look at the technology, however several did. Those who were prepared to complete testing have all confirmed our claims; however none will publicly go on record.
In early 2006 Steorn decided to seek validation from the scientific community in a more public forum, and as a result have published the challenge in The Economist. The company is seeking a jury of twelve qualified experimental physicists to define the tests required, the test centres to be used, monitor the analysis and then publish the results.
Steorn has decided to publish its challenge in The Economist because of the breadth of its readership. "We chose it over a purely scientific magazine simply because we want to make the general public aware that this process is about to commence and to generate public support, awareness, interest etc for what we are doing."
