Default What is Project Greenglow... a breakthrough in prop.physics?

BAE SYSTEMS (The company formed from the merger of British Aerospace and Marconi Electronic Systems) is currently running a speculative research programme in the realm of gravitational physics with the aim of initiating some new areas of research and priming technology development, with the hope that subsequent implementation, could lead to significant advances in the aerospace industry. For historical reasons we have called this programme project Greenglow.

We see Project Greenglow as the beginning of an adventure which other enthusiastic scientists from academia, government and industry might like to join, particularly those who believe that the gravitational field is not restricted to passivity and who have new theories, to the contrary, which they would like to propose. The network provided by Project Greenglow could provide the arena for publicising, debating and pursuing these ideas. We feel that emphasis should be given to those theories which can be tested in a laboratory at moderate cost and which, if successful, could be developed into technical applications for the aerospace industry.

Our approach to the research programme will be much along the lines of the newly established NASA Breakthrough Propulsion Physics Programme which has, as its central theme, the goal of developing propellantless propulsion. We hope that there will be elements where our two programmes come together and we will support interaction between the two. Following the lead set by NASA, it is intended that most of the administrative effort and day-to-day communications will be conducted via the Internet. Also, the aim will be to keep the research programme as open as possible, within the restrictions imposed by academic ownership and commercial return on investment, as we recognise that there is a great deal of interest throughout the world on gravitational research, particularly on the possibility of the control of gravitational fields. We may wish to harness this support in our quest for funding.

Due to the major interest in propellantless propulsion, Project Greenglow will contain a part where Future Concept Engineers can speculate on the impact which advances in gravitational technology might have on the design and sphere of operation of aerospace vehicles of the future. Artistic interpretations of these ideas should further stir the imagination of the scientists and engineers who participate in the project.

To determine the level of professional interest in this venture, we are planning to hold a Discussion Meeting,where some of us can get together and describe our present vision of Project Greenglow and talk about the way forward. Details of the Time and Venue will be posted on the Netlater. At this Meeting we would hope to form a small Steering Group, whose main tasks will be maintaining programme cohesiveness and awareness, the arranging of a series of topical seminars and the planning of a larger event (akin to the NASA BPP Workshop) next year for the presentation of ideas and results and agreeing the next stage in the collaborative programme.

The term breakthrough propulsion refers to concepts like space drives and faster-than-light travel, the kind of breakthroughs that would make interstellar travel practical.

For a general explanation of the challenges and approaches of interstellar flight, please visit the companion website: Warp Drive: When? The Warp-When site is written for the general public and uses icons of science fiction to help convey such notions. This website, on the other hand, is intended for scientists and engineers.

This research falls within the realm of physics instead of technology, with the distinction being that physics is about uncovering the laws of nature while technology is about applying that physics to build useful devices. Since existing technology is inadequate for traversing astronomical distances between neighboring stars (even if advanced to the limit of its underlying physics), the only way to circumvent these limits is to discover new propulsion physics. The discovery of new force-production and energy-exchange principles would lead to a whole new class of technologies. This is the motivation of breakthrough propulsion physics research.

Objectively, the desired breakthroughs might turn out to be impossible, but progress is not made by conceding defeat. Reciprocally, breakthroughs have a habit of taking pessimists by surprise, but can equally remain elusive. By proceeding in small, incremental steps that focus on the immediate questions and by emphasizing the reliability of the findings rather than their long-range implications, relevant and dependable knowledge will result. Regardless of whether the breakthroughs are found, this inquiry provides an additional perspective with which to seek answers to the lingering unknowns of our universe.

Status of the NASA Breakthrough Propulsion Physics (BPP) Project
All NASA support to sustain cognizance on these possibilities has been withdrawn as of October 1, 2008. The final NASA contribution was to assist in the compilation of a graduate-level technical book, Frontiers of Propulsion Science, which is due out in early 2009. This book (750 pages, hardback) will be volume 227 of the series, Progress in Astronautics and Aeronautics Series, which will be published by American Institute for Aeronautics and Astronautics (AIAA).

Prior to this point, the project's leader, Marc G. Millis, continued to monitor and assess a variety of ongoing research with the assistance of an informal network of volunteers scattered across academia, industry, various NASA Centers, and other Federal labs. During that time, several publications were completed to document the progress made. When funding for active research was available, which ran from 1996 to 2002, the project oversaw research into 8 different approaches, produced 16 peer-reviewed journal articles, and an award-winning website (Warp-When), all for a total investment of less than $1.6M. Also during that funded time, the BPP Project coordinated with related research funded at the NASA Marshall Space Flight Center. With the implementation of the 2003 Federal Budget (p.325), all advanced propulsion research was deferred, including these research efforts.

Accordingly, this web site will no longer be updated.

Status of Research
No breakthroughs appear imminent. This is a nascent field where a variety of concepts and issues are being explored in the scientific literature, beginning since about the early 1990s. The collective status is still at step 1 and 2 of the scientific method, "defining the problem" and "collecting data," but a small number of approaches are already at step 4, "testing hypotheses;" with experiments underway.

Cautionary note: On a topic this visionary and whose implications are profound, there is a risk of encountering, premature conclusions in the literature, driven by overzealous enthusiasts as well as pedantic pessimists. The most productive path is to seek out and build upon publications that focus on the critical make-break issues and lingering unknowns, both from the innovators' perspective and their skeptical challengers. Avoid works with broad-sweeping and unsubstantiated claims, either supportive or dismissive.

I don't know about this project, but here are my notes about Marconi (as they're handwriiten from about Jun-08):

* Dead programmers (UK) Marconi MoD 25 deaths
in 1970s and 1980s
