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.

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
Real Engineering explains how solar sails work in the video below:
In orbital space settlements water recycling is essential. So it is quite worrisome when we read the following article on ScienceDaily:
Get over it? When it comes to recycled water, consumers won’t
To cite from this article (my emphasis):
If people are educated on recycled water, they may come to agree it’s perfectly safe and tastes as good — or better — than their drinking water. They may even agree it’s an answer to the critical water imbalance in California. But that doesn’t mean they’re going to use recycled water — and it sure doesn’t mean they’ll drink it.
The problem is that educated people are disgusted to use a perfectly safe product that is necessary for staying alive. Perhaps people should not think too much about the origin of their tap water – if education is apparently not sufficient in this case.
WikiHouse is a project that applies the concept of Open Source Design to architecture. The idea is to print patterns on a plate of plywood, which are then mechanically cut by a milling machine – resulting in a kind of construction set. Continue reading WikiHouse
The Guardian reports a study that shows that about 300 million people live on land that will be flooded by 2050 as a result of rising sea levels. In comparison the US population was about 327 million in 2018. Continue reading A new home for 300M people
Soviet-Russian cosmonaut Alexei Leonov has died at the honorable age of 85. He is known for being the first human to have made a space walk. As such he is an important figure in the history of space exploration and the eventual humanization of outer space. May the Universe have his soul. And we also want to express our condolences to his loved ones.
Matthew S. Williams has written a good and elaborate article about space habitats on Interesting Engineering:
Are Space Habitats the Way of the Future
Williams discusses the basics of orbital space settlement and the major benefits and the important problems associated with this concept.
