The G-Files: Part 1 of a series...

Given the recent revival of interest in Project Greenglow following the recent publication of a memoir by the project head Dr Ron Evans, as well as the possibility of a BBC "Horizon" documentary on the subject in 2016, I decided to make available my personal collection of papers and other relevant information, relating both directly and indirectly to Greenglow. Here are some introductory presentations and papers to get you started - more will follow in the coming weeks and months. Here's a quick summary of the documents:

• The report of the 1990 BAe-University Round Table on Gravitational Research - This is referred to in Dr Evans' book, and illustrates the interests of university researchers prior to Project Greenglow.
• "Quest for a novel force: a possible revolution in aerospace", a 2003 paper by Prof. John E. Allen, an advisor to Project Greenglow. This paper is also referred to in Dr Evans' book.
• "Goals & Metrics for Project Greenglow", a 2001 report by Prof. Colin McInnes and Spencer Ziegler of Glasgow University, commissioned by the Project. It also describes ongoing activities at other companies and space agencies around the world.
• The Greenglow Graduate Lecture, a presentation given to new graduates joining BAE Systems as part of their company induction programme. A good "math-light" introduction.
• Greenglow History, a short history of the Project written by Dr Evans just prior to his retirement in 2005.
• "Electric Propulsion Study" by Dennis L. Cravens, the 1990 (final) report for the USAF. Also available directly from DTIC.
• "21st Century Propulsion Concept" by R. L. Talley, the 1991 (final) report for Veritay Technology. Also available directly from DTIC.
• "Guidelines to Antigravity" by Robert L. Forward, a seminal 1963 paper also referenced in Dr Evans' book.
• An overview I wrote for "Fortean Times" magazine in 2002, illustrating the state of research activities at the time, with particular attention to what was going on on the Internet.
• An account of the activities of Dr Evgeny Podketnov, including my meeting with him in 2000.

Best current propulsion blog

This blog was set up in response to the decline of the AmericanAntigravity site, and before the Tau Zero Foundation had got underway. Now that Centauri Dreams has rebranded itself the news site for Tau Zero, I would refer all those interested to that site for the latest news and information, partly because they have more time to devote to it and with a view to reducing the huge number of sites dedicated to the subject, which only seems to increase confusion and the propagation of errors.

More Gravity Anomalies?

Following on from the Pioneer Anomaly, there now appear to be several other spacecraft undergoing anomalous accelerations.

Warp Drive Symposium - London

If you can make it, this symposium at the British Interplanetary Society in November looks interesting. Not many confirmed speakers as yet, though. For those of you unable to make it, the following links to work by the known speakers may be of interest:

Remo Garattini:
Spacetime Foam and Vacuum Energy [PDF]
The Cosmological Constant as an Eigenvalue of a Sturm-Liouville problem and its renormalization [PPT]

Claudio Maccone:
Levi-Civita Effect in the polarizable vacuum (PV) representation of general relativity [PDF]

Unfortunately I couldn't find any references to the work of Jeremy Gardiner. If you know of any, let me know & I'll add it to the list!

Reversing the Casimir Effect

News on this development at St Andrews University, using metamaterials with negative refractive indices, first appeared last month, but there's now also a quite entertaining page explaining the principles for a general readership.

Useful Amounts of Photon Propulsion?

Just noticed this, apparently the first photon propulsion system to produce practical, useful amounts of force.

Hiddink's One Terminal Capacitor

Some time ago I was made aware of an overlooked invention from the 1970s, seemingly the result of a thought experiment, perhaps one of Faraday's himself, concerning the effects of turning a normal 2-terminal capacitor into a single terminal version. A description of the circumstances of the invention and its consequences in the words of the inventor (Joseph Hiddink) may be found here. It seems to have the potential (pun intended) for several applications - from the patent description:

Another object of the invention is to provide the means for producing high potentials which can be positive or negative in nature and which are adapted for use in the study of nuclear structure and nuclear reactions.

Still a further object of the invention is to provide a novel and improved means for constuction and operation of a high power particle generator.

Another object of the invention is to provide a novel and improved device for generating potentials of either positive or negative nature of such magnitudes so as to attract, bend or repulse radiation.

Still another object of the invention is to provide novel and improved construction of a device for generation of potentials of either positive or negative nature, to attract or repulse mass.

A further object of the present invention is to provide novel and improved means and its construction for making an inexpensive, yet effective Intense Neutron Generator with possibility for slow to fast neutron emission.

It now remains for someone with sufficiently deep pockets and well-shielded facilities to replicate it, as the inventor is now quite old and unable to fund further experiments himself.
