An Earthship is a brand of passive solar earth shelter that is made of both natural and upcycled materials such as earth-packed tires, pioneered by architect Michael Reynolds. https://www.ecohome.net/guides/1161/do-earthships-work-in-cold-climates/
Distillation desalination is one of mankind’s earliest forms of water treatment, and it is still a popular treatment solution throughout the world today. In ancient times, many civilizations used this process on their ships to convert sea water into drinking water. Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the world, and to treat water in other areas that is fouled by natural and unnatural contaminants. Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water contaminants.
If global warming is caused by too much carbon dioxide being released into the atmosphere by human activities, intercepting those greenhouse gases before they reach the atmosphere — or, better yet, sucking them right out of the sky — sounds like a logical solution.
That’s the promise of carbon capture technologies, one of the few climate change solutions that doesn’t just reduce the amount of carbon emitted, but can actually remove carbon from the atmosphere, thereby generating “negative emissions.” https://www.cbc.ca/news/technology/carbon-capture-faq-1.5250140
