We welcomed back Dr. Jim Woodward to the program to discuss the Mach Effect, Mach thrusters and drive, and breakthrough propulsion. During our discussion, Dr. Woodward mentioned his book, “Making Starships and Stargates which you can order at http://ssi.org/exotic-propulsion-initiative as this allows SSI to get a royalty payment on the sale of the book. If you buy the book through Amazon using TSS/OGLF portal, The Space Show gets a percentage of the sales price of the book. In addition, the Charles Platt article, “Strange thrust: the unproven science that could propel our children into space” can be found here: http://boingboing.net/2014/11/24/the-quest-for-a-reactionless-s.html. Finally, Dr. Woodward mentioned the paper written by Dr. Heidi Fearn, “New Theoretical Results for the Mach Effect Thruster.” You can download this paper at www.researchgate.net/publication/280134421_New_Theoretical_Results_for_the_Mach_Effect_Thruster. Note that in the final minutes of our program, Dr. Woodward spoke very softly and we were unable to get some of what he said as part of his final comments. While the 1 hour 56 minute program was divided into two segments, this summary will be in one segment only and short as the papers above tell the story. I urge you to read them and become familiar with Dr. Woodward’s work either before or after listening to this discussion which was at times very technical and heavy in the theoretical physics fields for gravitational forces, electromagnetic forces and more as he described the Mach Effect. In addition to the physics, since Dr. Woodward’s work is dependent on funding so he spent a good amount of time in both segments answering questions and telling us what it was like trying to get funding, approved proposals, etc. for cutting edge work or even work considered to be out of the box or on the fringe. His realistic assessment of the challenges posed by his and similar work goes to the point of why we don’t see more out of the box science & advanced projects being financed. In addition to the physics and funding discussions, we talked timelines for his having commercial uses for small Mach thrusters which would start off servicing satellites. This discussion covered both segments.

We welcomed back to the show Greg Meholic to speak about advanced propulsion concepts, rocket reusability, and much more.  During the first segment of our 84 minute program, Mr. Meholic first defined what he meant by the term advanced propulsion.  Given this definition, we moved forward to discuss various concepts, propulsion methods, and propulsion research. During this segment, we talked about several propulsion technologies and Greg said thumbs up or thumbs down to their being advanced propulsion.  When it came to nuclear, Greg classified it as an alternative propulsion method, not an advanced propulsion.  Again, don’t miss his definition.  We talked near and intermediate term advanced propulsion concepts though it does not appear anything is really close at hand.  His timeline for a possible advanced propulsion technology was around 20 years.  He said not only do we need to understand the physics much better,  but the propulsion method much compete with current systems and produce benefits including cost benefits.  As far as choke points on advanced propulsion, he said understanding the fundamental physics involved was a big one.  We then talked about funding which is now mostly from companies and other private investor oriented sources.  I asked lots of questions about funding, especially how does one know when the point is reached to either kill the project or keep it going.  Don’t miss what he said about this.  Listeners also asked many questions.  In replying to one listener, he said it would be hard to beat chemical rockets to LEO but the door opens up BLEO though the Moon can be done with chemical rockets.  When asked about the anti-nuke movement and the impact on the nuclear rocket, he had some interesting observations, especially regarding the views of younger people.  When asked for leading advanced propulsion people and concepts, he mentioned former Space Show guest Dr. James Woodward and his work with Mach’s Principle several times during our show.  Greg was also asked about the work of Dr. Sonny White at JSC for warp drive and M drive.  Greg had much to say about his work including Q thruster and M drive.  John from Ft. Worth called in to talk about M Drive & Mach’s Principle along with gravity and magnetic frequencies.

In the second segment, Ashley sent in an email asking about going to the Moon and Mars for settlement and sustainability, wondering if advanced propulsion was needed for either location.  You might be surprised by Greg’s response to this question so listen carefully.  He did say there would be different requirements for the Moon and Mars.  With Mars, he also spoke about radiation and travel times.  Greg then had some things to say about artificial gravity.  One of his comments was that if we understood more of the physics, an eventual advanced propulsion system might enable an artificial gravity system without spinning or the need for tethers.  Brad in Tucson sent in a note asking about reusable first stage rocket launch systems.  Greg was delighted with the question as he works on such systems in his day job and he had much to say and offer about reusable first stage rockets.  He went through a brief summary of some of his work plus those attempting to design such systems including SpaceX.  I asked about a payload penalty with reusability.  Don’t miss his answer.  Our next caller was Marshall and he took us back to the artificial gravity discussion.  Marshal was asking questions about the amount of time spent in 1g as opposed to various fractional gravity loads.  As the program was ending, Greg received the final question which dealt with comparing the quality of government research to private sector research.  He reminded the listener that there very little to no government research funding for advanced propulsion, that it was almost all private sector funding.  He said the private funding was investor based so it comes with a commercial profit focus.

We welcomed Dr. James (Jim) Benford to the program to discuss his book (he was the co-editor) “Starship Century,” and his chapter, Sailships, plus his editing of the book.  During our first segment of this 1 hour 26 minute discussion, Dr. Benford introduced us to Microwave Power Beaming, sailships, solar sails, terrestrial beamed power, in-space beamed power and more.  We talked about microwave beaming as a possible space weapon, the storage of beamed energy, and the use of the millimeter band width for beamed power.  Also in our first segment, we talked about possible time lines for development for interstellar travel.  In this discussion, our guest used Alpha Centauri B as a reference point.  Propulsion in general was discussed with a thumbs down for chemical rockets for doing anything like what we were talking about in this segment.  Listeners asked questions as to why interstellar travel was important at this time given it is so far into the future.

In our second segment, we talked about his goals in editing the book and the fact that if it is bought through the book’s website, www.starshipcentury.com, the proceeds are donated to legitimate interstellar organizations and research.   Jim listed several of the organizations being considered for receiving such proceeds and interestingly, most if not all have been guests on The Space Show over the years.  Dr. Benford mentioned conferences and the Arthur C. Clarke Center at UCSD.  We then talked about the Fermi Paradox and factor L as to the probabilities of finding intelligent life someplace other than Earth.  Faster Than Light Travel was a discussion topic, Jim was asked what his non-space friends thought of his microwave beam power work and interstellar travel.  A listener asked about students in these subject, particularly in the UK and the US.

If you have comments or questions, post them on The Space Show blog.  You can reach Dr. Benford through his website, www.jamesbenford.com.

Guest: Dr. John Brandenburg.  Topics:  We discussed his new book, the GEM Unification Theory, gravity, propulsion and more.  You are invited to comment, ask questions, and discuss the Space Show program/guest(s) on the Space Show blog, https://thespaceshow.wordpress.com.  Comments, questions, and any discussion must be relevant and applicable to Space Show programming. Transcripts of Space Show programs are not permitted without prior written consent from The Space Show (even if for personal use) & are a violation of the Space Show copyright.  The Space Show/OGLF is now engaged in its annual fundraising drive. Please check out our appeal at https://thespaceshow.wordpress.com/2011/11/21/space-show-2011-fundraising-campaign.  We welcomed Dr. John Brandenburg back to the program to discuss his new book, “Beyond Einstein’s Unified Field: Gravity & Electro-Magnetism Redefined.”  I urge you read his paper published in the Journal of Cosmology. “A Derivation of the Newton Gravitation Constant and the Proton Mass From The GEM Unification Theory of Baryo-Genesis” at http://journalofcosmology.com/JoC17pdfs/brandenburg2.pdf. Dr. Brandenburg & I have been friends for a very long time & our discussions are informal, sometimes meandering, & always great fun. At times this discussion was heavy into the physic so do bear with us.  In segment one, Dr. Brandenburg said that the GEM theory was a “theory of most stuff.”  He referred to the Gravitational Constant & the Planck Scale as well as the Middle Scale throughout the discussion. He provided the groundwork relating to Einstein and quantum mechanics, hidden dimensions, string theory, the 5th dimension, electro-magnetism & gravity theory.  He also referenced many times over the Kaluza-Klein theory & work by Sakharov.  An early question asked our guest to explain why there were different intensities of gravity on different planets.  Dr. Brandenburg talked about Big G, all matter being electromagnetic at the molecular level & ratios (with Earth)  used to predict the surface gravity of a planet made of rock.  In our second segment, Dr. Brandenburg went into more detail about his GEM theory which is also referred to as the Grandis et Medianis theory.  The Big Bang was discussed as well as what happened in the second before the Big Bang.  He also talked about string theory & its relationship to the GEM Theory.  A listener asked about the recent faster than light neutrino experiments. The experiment named OPERA was very simple & basic & most interesting.  In discussing this experiment & its results, he introduced us to tachyons which prompted a call from listener John in Atlanta & they spent some time discussing the physics of the GEM theory & what it might mean for propulsion.  To simplify this review, we now move forward to the need for portable fusion power & using gravity modification for space transportation.  While optimistic for gravity modification, Dr. Brandenburg was blunt in saying that without portable nuclear power, even with gravity modification, we would not leave the atmosphere & we would continue using big chemical rockets.  Don’t miss this discussion. We talked more about string theory & dimensions & then a listener asked about parallel dimensions.  Dr. Brandenburg had much to say on this topic as well. Near the end of our two hour discussion, I asked our guest about his next book & this opened up a different discussion line. Dr. Brandenburg is going to write about science, religion, the Middle East, Israel, ancient history, Greece, the Roman Empire & metaphysics before physics!  Look for him to be a guest on the show about this one.  We ended our show talking about thorium, thorium reactors, why thorium cannot be used for weapons, & natural nuclear events in Africa & on Mars which he discussed in detail when he was last on The Space Show.  Post your comments/questions on The Space Show blog URL above.  John can be emailed using brandenburgj@orbitec.com.
