ITAR (which I hate with a passion) Slammed by the Economist

Posted by Coyote on August 22, 2008

In my humble opinion, the greatest impediment standing in the way of greater business opportunity and international partnerships for the American space industry are our export laws contained in the International Traffic in Arms Regulation (ITAR), which I hate with a passion!

It is important for us to understand how ITAR (WIHWAP) can affect our space industry, because space-based solar power is such a huge undertaking that international partnerships will be required not only for construction, but also for ownership and development of an international customer base.

The Economist published an article yesterday criticizing ITAR (WIHWAP). The AIAA Daily Launch (an email news service for members of the American Institute of Aeronautics and Astronautics–you are a member, aren’t you?) described the article this way:

Weaponization, Environmental Risk, and Multinational Approaches

Posted by Coyote on August 10, 2008

Today I was asked by a politically-minded individual what political hurtles space-based solar power might face when confronted with questions of weaponization, safety, and multinational approaches. My reply is below. Please check my work!

“Your concern about weaponization of the system and environmental risks are proper and deserve solid answers. For the answers (and a whole bunch of other great information) let me point you to a special edition of Ad Astra magazine produced by the National Space Society.

Space-Based Solar Power: Part of a Balanced Energy Diet!

Posted by Coyote on July 29, 2008

Our good friend Geoffrey Styles of the GSW Strategy Group, LLC, gave a most thought provoking presentation at the Space Frontier Foundation’s NewSpace 2008 Conference In Crystal City, Virgina, on 19 July 2008. It was a great conference! They even provided us with a brief synopsis of our space solar power panel.

Included here are the slides he used to describe a new way of thinking of national energy consumption. \”SSP In a Changing Energy Diet\” Instead of discussing the energy “mix” of sources, he rightly points out that like calories in a person’s diet, not all calories are equal.

Space Solar Power Demo: WWWWW & H?

Posted by Coyote on January 12, 2008

It’s time to get busy again!

Our very good friend, Hu Davis, recently circulated some good questions regarding the who, what, when, where, why, and hows of demonstrating space solar power. He poses the questions from the perspectives of two groups; space solar power enthusiasts, and some NASA people who work the International Space Station (ISS). (Please note that like the rest of us, our friends at NASA-ISS are just brainstorming with us to see what help the ISS might be able to lend to advance space solar power concepts–there is no official NASA position or policy on any of this yet.)

“Why is the DoD interested in this?” Security at all levels!

Posted by Coyote on September 1, 2007

Yesterday at one of my alternate work locations (okay…another one of D.C.’s Irish pubs) a space skeptic asked me to write down all the security reasons that explain why the DoD is interested in space-based solar power. Fair enough. So this is what I wrote on the bar napkin: (I share it with you because that’s what I do!)

The Goal for 2050 and the Build Forward

Posted by Coyote on August 7, 2007

Enthusiasts and Skeptics,

To give you a basis for analysis, by 2050 the goal is to have forty or so concentrator-photovoltaic space-based solar power (SBSP) satellites in geostationary orbit, each broadcasting via microwave between 2-5 gigawatts of power to terrestrial electrical power grids, with 1-to-5 broadcast antennas that can beam power to as many locations.

This must be done using a sound business case. John Mankins calculates that this can be achieved by keeping the costs of delivery and assembly on orbit below $3,500 per kilogram–keeping the cost to customers below $0.10 per kilowatt/hour. This will drive robotic assembly and tug systems to pull these enormous structures from low orbits to geostationary. On orbit fueling stations will be required. Paul Werbos believes the best way to do this is to get launch costs down below $200 per kilogram.  But several other factors help make the business case. For example, if the price of other energy sources goes up it helps to close the business case for SBSP. Other factors include the efficiencies associated with solar collectors, energy conversion, antennas/rectennas, signal path loss, etc. Dennis Wingo and others have suggested that the first customers for space-based solar power will be international–in areas such as India and Japan where the price per kilowatt/hour is astronomical compared to the Americas or Europe. All of this goes into making the business case.
