Water – The Ultimate Disruptive Energy Source?

 Evan Parker, Terry Whall and Keith Miller

To create a sustainable future, energy must – critically – be universally accessible, affordable and possess a minimal carbon footprint. The urgent need for solutions for the world’s energy infrastructure is accepted by most but despite the hype, clean energy systems (eg solar, wind, fission) will struggle to supplant fossil energy at global scale any time soon.  

A small company in southern England claims they have developed a process involving water that produces thermal energy in excess of the input electrical energy. They suggest this could be used initially for domestic application – space heating. Their energy cell comfortably outperforms heat pump technology and is less expensive to install and operate – indeed a simple shoo-in for the conventional gas boiler. It has a lower carbon footprint than all competing energy systems and requires only a modest water supply. In principle it can be deployed quite soon.

This energy cell technology can be scaled up to meet a large fraction of total energy modern society requires.

Evan will introduce this potentially groundbreaking discovery and will cast a sceptical eye over such a contentious proposition. He will describe how by passing an electrical current through water to establish a plasma produces energy in the form of high-pressure hot steam. The extent that is well in excess of the input energy has been independently validated and will soon appear as a peer-reviewed journal publication. 

This is a very live topic and Evan will provide an update on the technological and scientific issues – including the current theoretical understanding of the process. He will endeavour to provide some clarification as to whether water – the stuff-of-life – can also help human beings to live and prosper on planet Earth.

The authors are all seasoned entrepreneurs particularly Keith Miller, who is heavily involved in the renewable energy sector and is the principal investor in the current project.  Evan Parker and Terry Whall, who advise Keith, are Emeritus Professors of Physics and have co-founded multiple companies that have attracted millions in investments for solar cells, innovative software and quantum detectors. They collaborate with Arizona State University to apply their patented quantum sensor to the search for the elusive dark-matter particle.
