The main challenge to make space colonization a reality is a relatively inexpensive method of launching objects into orbit. Even after six decades of spaceflight we still rely upon chemical rockets as the principal way to get off this planet.
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.
The video below provides an excellent view of what a O’Neill Cylinder would look like.
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.
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:
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.
