Recently we discussed the intercropping of coffee and bananas, though this is far from the only possible combination. Here are a few links to other examples of polyculture:
Rubber with coffee or cocoa
Coffee and macadamia
According to the first link the combination of rubber and lemons were never profitable. This because of the low price of lemons. However, this might (or not) be different if the peels would be used to produce textiles.
The second article states that not only does the combination of coffee and macadamia result in much larger yields but also improves soil fertility.
Space colonization will only be viable if we are able to launch stuff into outer space at reasonable cost. Currently spaceflight depends on chemical rockets to reach orbit. However, chemical rockets suffer from a severe bottleneck. Continue reading Laser beam propulsion
Casey Schreiber explains in the video below the Garden City concept as envisioned by Ebenezer Howard.
Here is an interesting read by Jean-Yves Tizot on the political theory behind the garden city movement.
We will discuss the topic of garden cities in more detail in a future posts, in relation to, of course, space habitats (O’Neill cylinders in particular), permaculture and land ownership.
The video below provides an excellent view of what a O’Neill Cylinder would look like.
Technological progress and innovation are by no doubt important issues for the success of the humanization of outer space. Hence we need to consider the role patents will have to play in the society and economy of future space settlements. Continue reading On Patent Reform
We are great fans of permaculture, as it perfectly fits into to the second of the Four Goals as formulated by O’Neil:
There should be found an optimal living climate for the entire world population
But what is permaculture? In the video below the principles of permaculture are explained.
One type of permaculture is the food forest and this is explained in the video below:
Food forest are nice way to realize to vision O’Neill had for the design of the interior of the O’Neill cylinder: villages separated by forests. And additionally it combines goal #2 with #1, to eradication of hunger and poverty.
One major issue orbital space habitats will face is the need to build a large amount of houses and other building quickly and at reasonable cost. The video below illustrates the use of so-called Habiterra bricks.

Though the term Banana Republic is usually used as a pejorative to denote corrupt failed states. However, it might be time to improve the meaning of this phrase.

As distances within a space habitat will be rather small, only a couple of kilometers in most designs , bicycles will be an excellent mode of transportation for space settlers. Promoting cycling will also have environmental and public health benefits. Continue reading Public bicycle system
The Guardian has a good article about a campaign to make Cleveland, Ohia (USA) a lead-free city. The article also contains a table with some of the negative consequences of lead exposure on the health of children.
