Recycled water

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.

Organ cultivation

Last week Japan announced it would allow experiments to grow human organs in animals. These experiments are controversial, not in the least place because of animal welfare concerns and the possibility of cross-species diseases. However, xenotransplantation is not the only line of research pursued to solve the shortage of donor organs. Continue reading Organ cultivation

Future Fuel

Not directly related to space settlement, but still interesting to think about.

Fascinating Future

The age of (cheap) oil is doomed in the long run, even if we do not care about climate change, as petroleum is a finite resource which would eventually be depleted. However, our modern industrialized society requires a lot of energy and without it our planet cannot sustain a ten billion population.

Electric vehicles and public health

Our regular reader will know that we are quite hawkish when it comes to air quality and public health. One of the measure we have proposed is for space habitats to ban the use of internal combustion engines. A study by researchers from Cornell University provides a solid scientific base for a complete ban on internal combustion engines. Continue reading Electric vehicles and public health

Polymer waste and recycling

Plastic waste is a major environmental and social problem. The fact that plastics or polymers hardly decompose naturally is one of the contributing factors to the issue of this type of waste. Though polymers could be recycled only a tiny portion of separately collected plastic waste is actually recycled. Continue reading Polymer waste and recycling
