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
Science Daily reports yet another breakthrough in the development of artificial wombs. Researchers are now able to keep extremely premature lamb fetuses alive in an artificial uterus. If this development continues, it will be possible in the foreseeable future that the entire gestation could happen outside the body. Continue reading Artificial wombs progress
On ZDNET an interesting article about Markforged – a company that is working on a mass production 3D printer. As we have previously pointed out on this site, 3D printing is along side with in situ resource utilization one of the key technologies that will be of critical importance of making space settlements independent from terrestrial imports.
Waste management is an important issue for any community and space settlements will not be different. For several reasons, such are pollution and traffic congestion, running garbage trucks through the streets is a bad idea. So space habitat designers should consider alternatives. One interesting concept is illustrated in the video below:
Around the world scientists are developing robots for agriculture.
This Australian robot is suitable for open field farming:
As pointed out earlier too many people spend to less time on physical exercise and this seriously affect public health. A serious challenge for many people is to schedule regular work outs in their time tables. The DeskCycle is a tool that allows people to exercise while simultaneously doing something else, such as work.
Two Italian fashion designers have developed a technique to make a silk-like fabric from citrus waste, called Orange Fiber. The orange juice industry produce a very large amount of waste in the form of peels. The use of citrus peels as a resource for the production of textiles, is interesting as it increase the value of citrus fruits and hence potentially increasing the income of citrus farmers.
In the previous post I did not discuss particular technologies to purify waste water and to turn it into clean water. One way to remove minerals from waste water are algae.
As orbital space settlements will get most of the energy from solar power, there is little use for biofuel. However, algae have a lot of other useful applications. Continue reading Sewage and Algae
