Biography

[edit | edit source]

 

 I'm an advanced space systems engineer (i.e., a rocket scientist). That means mostly working on next generation ideas and projects, rather than today's hardware. I attended Columbia University, where I studied astrophysics and engineering, and first started working on space concepts. I then worked for the Boeing Company for 24 years, from 1981-2005, all of it in their Space Systems division. The last major project I worked on was the Space Station, where I variously was a lead systems engineer, wrote operating procedures, and tested software.

 Since leaving Boeing, I have continued with my own design and engineering work. Currently I am working on the Seed Factory Project, whose goal is to develop sustainable self-improving production systems. Such systems have the potential to end material scarcity and expand civilization throughout the Solar System and beyond.

 I was supported by the public much of my life, in the form of scholarships and working on government contracts. Now that I work for myself I want to give back to society in the form of open-sourced works like the books and articles below, and through community projects like the South Atlanta Maker Network.

 If you want to contact me directly, the best way is the email above. I tend to have the same user name (danielravennest) for most of my public accounts online (including Wikibooks and reddit). Other methods like posting to my discussion page here might work, but I am on too many forums and sites to track them all. My personal email is the one I check the most often.


The Seed Factory Project

[edit | edit source]

 

 My current work is on systems designed for self-improvement. Space projects have been limited by the cost and difficulty of lifting everything from Earth. One way to get around that is to send a starter set of equipment (a seed factory) to space, and use local materials and energy to build more equipment for the factory itself, plus finished products like any other factory. The instructions for the added equipment weigh much less than the equipment itself, and you don't have to spend time and money trying to save weight on, for example, an entire human outpost and everything they need to live and work.

 By early 2013 I realized this approach will work just as well here on Earth, because the laws of Nature are the same everywhere. A single starter set can grow to produce an increasing range of products, including more starter sets. This kind of exponential growth has the potential to solve several of the problems facing civilization. So I shifted my focus to demonstrating the first such starter sets here on Earth. I still have a strong interest in space projects, but seed factories in space can wait until there is experience with them here.

 I call them "seed factories" because a larger factory grows from them in the same way a tree grows from a seed. In fact, an automated and self-expanding system like this meets many of the definitions of artificial life. Such systems can even include living things like plants for the products they provide. So the name aptly merges the ideas of living and industrial systems.

 A set of tools and machines by themselves are inert. A complete functioning system also includes resources like human labor and raw materials, and energy to run things. The final element is knowledge. That includes the skills and experience to use the equipment, plans and instructions for what to build, and supporting information like reference books. The necessary combination of Tools, Resources, Energy and Knowledge is called the "TREK Principle".

 There is only so much one person can do. So I started the Seed Factory Project as an open-source collaboration to develop and demonstrate actual working versions of this idea. The approach we are taking is for the designs and technology to be open for anyone to use. The physical hardware would be privately owned by individuals or cooperatives. The hope is that will lead to the widest use and the greatest benefit for the most people.

 The project is nowhere near finished. Anyone who is interested is welcome to contribute. Most of the documents are here on the Wikibooks site and listed below. Other file types like spreadsheets and pdfs are either online elsewhere or available on request.

Books in Work

[edit | edit source]

 

 I am in the process of integrating what started as separate books on space systems and seed factories. Space systems were most of my previous career, and I noted a lack of a modern, future-oriented text for the next generation of students. The seed factory idea had first been investigated for use on the Moon by NASA in 1980. It was set aside because the technology of the time wasn't up to the task. When I came across it again, technology was much better, and Earth applications seemed more important, so a separate book seemed the right approach. As I developed the ideas more, it became evident that the technologies and methods for Earth and space are not so different. So the books will be treated as a pair of volumes covering different applications of the underlying technology:


  • Better Worlds vol. II: Space Systems Engineering - The principles of engineering apply everywhere, but the environments of space are different and everything is in motion relative to the ground. This volume starts with subjects like orbital mechanics, then covers space transport, because to do anything in space you first have to get there, and generally move around once there. General types of space projects are discussed next, followed by specific locations and projects located there. The ideas from volume I are incorporated as appropriate. It is a future-oriented book, and includes ideas and methods not typically covered in aerospace engineering courses.

 No pair of volumes can cover the entire scope of these subjects. We plan to include extensive references to other sources, but online ones tend to be ephemeral. I have accumulated a personal library in the course of my work. If you are unable to find it elsewhere, I will be happy to lend out items on request for personal use.

New Material

  • Ideas and Notes - This page is for saving thoughts which are not developed enough to start a separate article or book section.
  • Air Mining - The concept of mining the upper atmosphere from orbit for fuel and air.

[To Merge] - A more complete description and quarterly status reports and a start at an article series to find out more. It covers the concept, history, design, and operation of self-expanding automated production systems. It's on Wikibooks in the spirit of open-source collaboration. I started writing it, but We've taken stab at setting up a web page and GitHub repository, but I'll be the first to admit they need more work.
