Greenglow and the Search for Gravity Control - Ronald Evans ***

This is an unusual book with an unusual back-story. It’s no surprise, of course, that Britain’s largest aerospace company, BAE Systems, has a vested interest in countering the force of gravity – rockets and aircraft are designed to do just that. But over a period of about ten years, starting in the mid-1990s, BAE decided to take on the law of gravity itself. In what became known as 'Project Greenglow', the company sponsored fundamental research in university departments around the UK. In effect, they were looking for loopholes in the current understanding of physics which might point the way to radically new forms of gravity control.

Extraordinary as it was, Project Greenglow was in tune with its times. On the other side of the Atlantic, NASA was running a 'Breakthrough Propulsion Physics' programme which was similarly concerned with potential aerospace applications of new, as-yet-undiscovered physics. There were tantalising hints that such things might be just around the corner. In 1996 a Russian scientist named Evgeny Podkletnov made headlines with his announcement that a rotating superconductor could act as a kind of 'gravity shield'. One of the many strands of the Greenglow project was an attempt – an unsuccessful one – to duplicate Podkletnov’s experiment in a UK laboratory.

The driving force behind Greenglow was Dr Ronald Evans, a senior engineer in BAE’s Military Aircraft division until his retirement in 2005. His own expertise lay in the more conventional fields of aerodynamics and electronics, but the idea of 'gravity control' was something that had fascinated him since the 1980s. Dr Evans eventually succeeded in persuading his superiors at BAE Systems to set up a research project on the subject, before moving on to the equally difficult task of convincing academic researchers to take on what must have looked suspiciously like fringe science. The story of how all this drama unfolded, together with the ensuing highs and lows of Project Greenglow itself, would probably make a great book – but it’s only a relatively minor thread running through the book Ron Evans has actually written.

As I said at the start, this is an unusual book. It isn’t any of the things you might expect it to be. It isn’t a narrative history of Project Greenglow, although some of that does come across in passing. It can’t really be classed as a popular science book, because there are too many equations – although most of these can be skipped over without any great loss. It isn’t a textbook, because textbooks focus on what is known and understood, while this one repeatedly draws attention to what is not known or not understood. Most emphatically, however, this is not a crackpot’s book. It pushes on boundaries without going over them. The author points out gaps in current theories and describes other people’s speculations (rarely his own), but he doesn’t make any unsupportable assertions, or claim that such speculations are correct and that mainstream science is wrong.

So if the book isn’t aimed at the typical pop-sci reader, the typical textbook reader or the typical alternative science reader, who is going to enjoy reading it? The answer is all the above! The writing, if you’re prepared to skip over the (generally unnecessary) equations, is as lucid and well-structured as the best popular physics books I’ve read. The technical content, for the most part, really is textbook stuff – but presented in a fresh, innovative way (with crystal-clear diagrams) that draws attention to analogies and problems that many readers, even those with a solid grounding in physics, may never have encountered before. As for those alternative souls desperately looking for the next breakthrough or paradigm shift, this may not be the kind of glib, anti-establishment fare they’re used to, but they’ll certainly find plenty of food for thought.

Review by Andrew May


  1. I used to belong/still to the Breakthrough Propulsion-Project Greenglow group that still has restricted membership via yahoo groups. As astra, Ron Kita, Chiralex

  2. I have ever since College thought that this Anti-Gravity must be possible, in all fields of Science there are explanations to Physical phenomenon. But this is the physics version of the making of Gold from base metal. I'm sure that we are so tied to Einstein, that we dismiss the possibility of alternative properties. So with simple experiments some can show other things like levitation of a magnet. Anti-matter has to be the answer, this has bothered me since early years. Newton may have been hit by the apple, but what if it went the other way ?

  3. Its already been done by the Nazi's in WW2. Look at operation High Jump and operation paper-clip.

Adam Roberts - Four Way Interview

Adam Roberts is commonly described as one of the UK's most important writers of SF. He is the author of numerous novels and literary parodies. He is Professor of 19th Century Literature at Royal Holloway, London University, and has written a number of critical works on both SF and 19th Century poetry. His latest novel is The Real-Town Murders.

Why science fiction?

Because it's the best thing in the world. I work for the University of London, which is to say: in effect, I'm paid to read books (and teach them, and write about them) and that means I read a lot of books; and that means you can believe me when I say that SF/Fantasy, and especially (even though it's not something I write) YA SF/Fantasy, is where all the most exciting writing is happening nowadays. You might wonder why I think so: but that's a whole other question, and you've already used up your four ...

Why this book?

So, I came across an account of one of Alfred Hitchcock's (many) unfinished projec…

UFO Drawings from the National Archives - David Clarke ***

This is a lovely little book that, sadly, not every reader will see the point of. If somebody’s anecdotal account of a presumed alien encounter is obviously a misperception of a mundane occurrence, or else too vague – or too far-fetched – to be taken seriously, then it’s all too easy to dismiss it as worthless. But that’s missing the point. The fact that so many incidents are reported in these terms makes the witnesses’ testimony worthy of serious study – to teach us, not about extraterrestrial civilisations, but about our own culture.

That was the core message of David Clarke’s excellent How UFOs Conquered the World published a couple of years ago. Now Clarke is back with another take on the same basic theme.  His day job is Reader and Principal Lecturer in Journalism at Sheffield Hallam University, but for the last ten years he’s also acted as consultant for the National Archives project to release all of Britain’s official Ministry of Defence (MoD) files on UFOs. Throughout the Cold…

Crashing Heaven (SF) - Al Robertson ****

There's an engaging mix of powerful thriller and science fiction in this impressive novel. After the Earth has been rendered uninhabitable, human life is limited to vast space station. Our central character, Jack, has a symbiotic artificial intelligence, Hugo Fist, designed to destroy other AIs in a mysterious collective that is said to have committed an atrocity - but with a kick in the tail that because of an unbreakable contract, Fist will take over Jack's body in a few weeks' time.

Al Robertson packs remarkable technology concepts into the cyber side of this story, from AI corporations that act as a pantheon of gods to the 'puppet' that is Fist (he usually come across as a virtual cross between Mr Punch and an evil ventriloquist's dummy). Robertson does all the cyber stuff so well that it's easy to miss that this is, in effect, a myth in electronic clothing - you could substitute the myths of 'real' Greek gods and magic for what happens here. Alt…
