§ 4.1.1 Zero Gravity to Any Artificial Gravity by Centrifuge

With the exception of the lunar surface, the space environment offers zero gravity, which creates many options not available on Earth. However, if gravity is needed for a process, then artificial gravity can easily be made available by use of a rotating complex to produce a centrifugal force, which is equivalent and practically indistinguishable from gravity. Indeed, any strength of artificial gravity can be provided, whatever is ideal. A rotating industrial facility offers different strengths of gravity at different distances from its axis.

Zero gravity and the absence of wind facilitate the handling of very large components and their assembly into giant structures impossible to build on Earth.

The SMF itself will be a 3-dimensional facility with a layout quite different from Earth factories. The SMF also won't be nearly as massive as an equivalent manufacturing facility on Earth due to gravity considerations.

Zero gravity means no convection currents in molten material, which allows purer material separation processes, mixing of materials which would separate due to gravity on Earth, and perfect crystallization processes (e.g., for solar cells and microelectronics). Many alloys and crystals are easily producible in space which are practically impossible to make on Earth.

PERMANENT has received several questions from people related to the handling of materials in zero gravity. In any case where gravity facilitates handling of materials, rotational artificial gravity will give us the capability to use conventional Earth handling techniques so that we can employ Earth-standard processes.

Nonetheless, there are countless ways to transport and handle material in zero gravity, most of them based on Earth methods at mines and factories, including:

  • Pipeline screw conveyors or centrifugal pumps for raw materials (tunnel with helical blades or propellers)
  • Gas pressure and pumps (mentioned in some literature but I don't like it)
  • Various kinds of conveyors, elevators and apron feeders
  • Packaging and ballistic transport

I don't see significant problems in the category of transport, but I do see significantly more flexibility and advantages. > Manufacturing, Industry > Space Environment > Zero Gravity to High-G Centrifuge


PERMANENT needs a PHP / MySQL (actually, MariaDB) programmer. Are you a PHP / MySQL programmer interested in getting into space development as a career, or already working in space development? Or do you know somebody else who might be interested?

There is an ongoing process to update this website in 2019 with a target relaunch in 2020.
This website is actually very out of date. Much of the website text content was written in the 1980s to early 2000s, but that's a different matter. As regards PHP / MySQL, some offline databases go into the 2010s, as regards professional publications, engineers, companies, etc., and this is what we need programming help with. We are updating our databases on people, organizations, publications, and other things, for open source space development for all.

The current status is we have some working databases which we have been using internally for a long time for organizing professional publications, and to track people (authors, R&D people, other professionals, quality volunteers, journalists, etc.) and organizations. We want to put information online for the general public pending a security review of the programming code.

Step 1 is fixing some bugs in what we already have, the PHP code. It is functional, and been used a long time, but there are some bugs.
Step 2 will be improving the system. Some small improvements would help its usability.
Step 3 will be a security check for putting it online for the general public to be able to access and use, but with reasonable protection against hackers.
After Step 3, the main mission is accomplished, as regards PHP / MySQL, though of course we hope to keep people engaged and happy, and the sky's not the limit.

This is a volunteer, unpaid role at this point in time. A limited paid role would be considered on a tight budget, such as for at least bug fixing with some minor improvements, and/or a security review of our code before it goes online publicly. If you or one of your friends or associates may be interested, please send an email to spaceprogrammer at ... of course this domain.

Reasons to do something yourself:

  • It will help save life on our special planet -- be part of the solution in your generation.
  • It will create and secure a better future for your children and grandchildren.
  • It could be an interesting, cool, and a fun adventure for your life!
