We welcomed back Jim Keravala, COO of Shackleton Energy Company, to update us on the latest news with Shackleton and their lunar plans. Visit their website for more information, www.shackletonenergy.com. During the first segment of our 1 hour 47 minute discussion, Jim introduced us to the Shackleton Energy plans for space development by solving the terrestrial energy problem facing Earth. The program Jim outlined is expansive and at times complicated so you will want to pay extra careful attention to our discussion. Jim talked about creating the Off World Foundation and the Off World Consortium which he fully explained in this segment. He also said the real path for space development required solving the earth’s terrestrial energy problem. He then explained his multi-billion dollar program which is in three phases starting with propellant depots, then lunar mining and manufacturing, followed by the establishment of space based solar power. Our guest talked about the many challenges but noted that investor caution was prevalent along with risk uncertainty. In this segment, he talked about the market, consortium participants, timelines, business and industrial challenges, and more. He also outlined the assumptions used in designing this program.

 

In the second segment, Jim talked about the Outer Space Treaty, regulatory barriers, rectenna placement, power distribution to the poorest and most needy of countries first, space advocacy, space settlement, the traditional space industry, and technology readiness levels (TRL) for the development of Off World program. Jim answered questions about program costs, suggesting that the first phase mentioned earlier would cost around $18 billion! He outlined the additional program costs and timelines, plus revenues received along the way being reinvested in the program. We talked about comparisons with other industries such as the oil and gas industry and their support for the Off World program. Several times in this segment Jim said this was the best way to drive the development of space and eventually space settlement. At the end of the segment, Jim offered a detailed conclusion & summary for the Consortium to solve the issue of terrestrial energy through the use of space.

Guest:  Gordon Woodcock.  Topics: Financial analysis for an SSP Power System, competing SSP ideas & plans.  Please direct all comments and questions regarding Space Show programs/guest(s) to the Space Show blog, https://thespaceshow.wordpress.com.  Comments and questions should be relevant to the specific Space Show program. Written Transcripts of Space Show programs are a violation of our copyright and are not permitted without prior written consent, even if for your own use.

We welcomed Gordon Woodcock to the program to discuss his ISDC 2013 financial analysis presentation for an SSP power system.  This presentation is available for your consideration on after the program summary on The Space Show blog for this program per the above URL.  In addition, visit the SolarHigh.Org website for more information at www.solarhigh.org.  In the first segment of our two part 90 minute discussion with Mr. Woodcock, we were introduced to the concept of space solar power from the initial work of Peter Glazer followed by microwave expert Bill Brown.  Mr. Woodcock then discussed the need for large space transmission and Earth based receiving antennas, the need to use GEO for the SSP satellites, and some basics about beaming microwave power.  Economic & financial concepts were introduced along with the need for systems to be affordable, reusable and generate acceptable ROIs.  However, as you will hear, all of this is hard to do at this stage given the need for research and demo systems for proving out the best engineering approaches and designs.  We talked about solar efficiencies and the trade in mass with thin film lighter material with only about a 30% energy efficiency but because of their lighter weight, the trade allows us to launch & deploy bigger systems giving us more bang for the buck, so to speak.  Gordon also talked about efficient transmitter systems & the use of 5.8 GHz.  In this segment we talked about lowering launch costs, increasing the launch rate, and the competitive price for terrestrial electric power.  Earlier in the segment, Gordon  suggested the need for a one year payback but Tony sent in a question suggesting longer paybacks, all of which were acceptable scenarios as long as they were roughly competitive with highly risky terrestrial investments.

In the second segment, we talked about starting with smaller systems & demos, all followed by incremental project development.  We also talked about specific space and terrestrial antenna size and ratios as well as the size of power systems, even up to 2,000 MW or larger.  Mr. Woodcock went over the idea of raising the frequency and what this might mean for a demo as well as an operating power project system.  Questions came in regarding on orbit system repairs and maintenance.  Our guest said the systems would need to be serviced robotically.  We talked about the environment for SSP systems at this time & into the near and medium term & possible fossil fuel competition given new energy extraction methods.  Crowd funding was suggested as a way to fund some of the needed research which our guest said could be done in many competent labs in the U.S.

Guests: John Batchelor, Dr. David Livingston. Topics:  The 11th Annual California Round robber for policy debate.  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. Written 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. This program is archived on The Space Show website, podcasting, and blog sites with permission from John Batchelor. Please visit the John Batchelor Show website for more information about this fine program, www.johnbatchelorshow.com. The topics in this 11 minute plus segment focused on the 11th annual high school California Round Robin for policy debate which was held Friday, Feb. 17, 2012 at theCollegePreparatory School inOakland,CA.   I was one of four critics (not judges) asked to participate and advise the debating teams on how realistic their presentations were in terms of what is actually done regarding the subject in the space industry.  The question the debaters focused on asked if theU.S. government should pay for and develop space solar power.  One team took the affirmative.  The other team accepted the need for space solar power but took the position that it should be paid for and developed by the private sector.  High School debate rules were followed.  In the coming weeks the debate audio will be uploaded to a special website for everyone to hear.  When the audio is available, I will modify the archives for this program to include the URL so those of you interested in hearing it can do so.  In addition to critiquing the students, each of the four of us (critics) had an opportunity to address not just the two debate teams but also the 60-70 adults in the room.  We stressed the possibility of understanding, seeing, and valuing space as a possible path for solutions to many of the problems we all face today.  In talking to the students after the debate, they were all open to STEM college programs, space, science, and technology careers.  They were actually excited about the debate, the topic, and their future.  During this segment with John Batchelor, I went into more detail about the actual debate, how they handled the multiple disciplines they talked about including engineering, technology, space issues, beaming issues, business, financial and economic issues. When the debate ended, we took questions from the students and the adults. Some of the questions dealt with space debris, microwave beaming and space weapons, the Outer Space Treaty, space liability issues, and an aging space workforce.  Please post your comments regarding this John Batchelor Show segment on The Space Show Blog.  If you want to email John Batchelor you can do so through me or their respective websites.
