We welcomed Dr. James Dewar and Dr. John Jurist back to the show to discuss nuclear propulsion and rocket. During the first segment of our 1 hour 40 minute discussion, Both Dr. Dewar and Dr. Jurist talked about the nuclear rocket technology, fuel, cores, past experiences, and how best to modernize the nuclear rocket and move forward with new development. Most of the callers talked technology so this first segment is very technology heavy. Space attorney Michael Listner sent in emails suggesting it would never happen due to the regulatory side of things plus he provided us with the UN Committee on the Peaceful Uses of Outer Space policy on using nuclear power in space (www.unoosa.org/oosa/SpaceLaw/nps.html). Listener Kristopher spoke to our guests about core options and fuels. Check out this site that he sent us: http://www.projectrho.com/public_html/rocket/enginelist.php#ntrvapor. Toward the end of the first segment, I said that after the break the second segment would focus on what to do to make the nuclear rocket policy and to start the program and develop this form of advanced propulsion. Both Dr. Dewar and Dr. Jurist agreed.

In the second segment, we did focus on the need for leadership and organizational structure for developing the nuclear rocket and starting with nuclear propulsion. We had several callers and emails addressing how to sell a nuclear rocket program. Dr. Dewar talked about the economic benefits, jobs, opening up more of space to economic growth and access. I asked about chokepoints and both our guests suggested the biggest chokepoint was the absence of young, passionate, and competent leadership. Related issues that came included how best to get the support of congress as well as the American people, plus why a nuclear rocket was important and should be developed.

We welcomed back Eric Lerner for updates on his Focus Fusion work and then later, his work in cosmology as he challenges the Big Bang & expanding universe theories.  In the first segment of this 1 hour 40 minute show, we focused on fusion.  For more information, visit http://focusfusion.org.  Since much of this discussion involves physics, technical explanations, and more, referring to the website will be helpful.  Eric started out with an overview of focus fusion (Aneutronic Fusion).  He made clear their goal was to demonstrate the scientific feasibility of focus fusion.  Eric then described the challenges, possible solutions and progress being made in reaching their goal.  I suggest you review these website pages to help you understand what he talked about:  http://focusfusion.org/index.php/site/category/C36; http://focusfusion.org/index.php/site/category/C63; http://focusfusion.org/index.php/site/category/C70.  During this segment, Eric explained in detail the process, the physics, the science and more of what they do, have done, and still need to do.  We talked about pulse power, time sequences, the amount of power needed, and what has to happen to get more energy out than what they put into their reactor.  Marshall called to ask about computer power needed and simulations compared to actual experiments.  Eric also talked fuel options and then he talked about their financial needs.  He said they would soon be doing both a short movie and a Kickstarter program.  In fact, he made a call for volunteers so if you are interested, email him at eric@lphysics.com.  Questions came up about the safety of their work, then listeners asked how they contain such high temperatures, even if for a fraction of a second.  He talked about the need for using tungsten & we talked some about tungsten supplies and pricing.  Charles called in with several questions and comments about fuels and then about instead of using tungsten electrodes why not use boron or beryllium as the low atomic weight would contaminate the plasma less.  Charles & Eric has a very interesting discussion about these matters.  We then did a theoretical comparison of the potential cost of fusion energy with coal, natural gas & other conventional fuels.  Near the end of the segment, Eric was pressed for timelines to commercial breakeven if he had adequate funding.  Direct Energy Conversion was our last session topic.

In the second segment, Tim called to ask about fusion for space propulsion.  Next, Eric talked about cosmology as he said there was a debate about the Concordance Model which supports an expansive universe and The Big Bang Theory.  Eric challenges this and in this segment, provided support for his challenge to the Concordance Model of the Universe.  He also pointed out that his book on the topic is still in print so if you are interested, use the OGLF Amazon portal to buy “The Big Bang Never Happened.” OGLF portal instructions are in all program summary statements and blog archives.  You can also email me for help at drspace@thespaceshow.com.  Eric’s discussion of The Big Bang Theory and why he says it is likely incorrect was most interesting and I urge you to carefully listen to what he had to say about this & cosmology in general.  He also talked about how difficult it is to be published if you have a contrary theory and how peer review science flows to the status quo.

Please post your comments/questions on TSS blog above.  You can contact Eric at his email address listed in this summary.
