Atmosphere to Water Generators: Veggies in the Desert

Atmosphere to Water Generators: Veggies in the Desert

The world is facing a water crisis. Atmosphere to Water Generators (AWGs) can help alleviate this problem in hot, dry locations.

As the population grows and climate change intensifies, water resources have become increasingly unpredictable and erratic. In arid environments, such as deserts, water is especially scarce. This is a major challenge for agriculture, as water is essential for growing food.

There has been growing interest in developing new technologies to produce water from air in recent years. The idea is not new; throughout history, ancient cultures have used dew fences and other passive means to harvest moisture from the air – even the very dry air of deserts. A quick look online shows several free or near-to-free ways to generate water, such as Kumulus water generators; solar-powered machines capable of producing 20 to 30 liters of healthy drinking water daily.

A new study published in Cell Reports Physical Science has demonstrated the potential of Atmosphere to Water Generators to produce water in arid environments using waste heat from solar panels. With SolarAtmosphere to Water Generators, it may be possible to grow food in the desert without relying on scarce freshwater resources. This could address the global water crisis and provide food security for a growing population.

 

How Atmosphere to Water Generators Work

Atmosphere to Water Generators work by using the heat from sunlight to evaporate water from the air. The water vapor is then condensed into liquid water. The process of evaporation requires energy, and the heat from sunlight provides this energy. The water vapor is then condensed into liquid water by cooling it down. This can be done by passing the water vapor through a cold pipe or by using a fan to blow cold air over it.

Atmosphere to Water Generators are typically made up of two main components: a solar collector and a condenser. The solar collector is used to collect the heat from sunlight. The condenser is used to condense the water vapor into liquid water.

 

Solar First then Water

In the system explained by the Cell Reports Physical Science study, the system was first designed to enable solar panels to work more efficiently; water production was just a happy byproduct.

Solar panels have been getting better and cheaper in recent years, but overall they still are relatively inefficient. This inefficiency is made worse by heat – a big problem for systems located in very hot deserts. Further, just like any other piece of electronics, a solar panel lasts longer when kept cool, which is also a problem in a harsh desert environment.

The solution was to coat the back of the panels with hydrogel, a product that absorbs water from the air at night, then releases it through evaporation as it heats during the day. As the water evaporates, it cools the solar panels making them work more efficiently and last longer.

This evaporated water is then captured and saved for crop irrigation. Deserts are places of extreme heat – daytime temperatures are hot, but nighttimes are very cool, making them the perfect place to maximize the performance of a system like this.

The study found that Solar Atmosphere to Water Generators can produce up to 1.5 liters of water per day per square meter of solar cell area. This is enough water to support the growth of vegetables in a desert environment.

The study’s findings can potentially revolutionize agriculture in arid environments, said the authors.

 

Challenges and Opportunities

There are a number of challenges that need to be addressed before Atmosphere to Water Generators can be widely adopted. One challenge is the cost. They are still relatively expensive, but the cost is expected to come down as the technology is developed further and the costs may be negligible when included in the design and commissioning of a large solar farm. More so when combined with the benefits of increased solar panel efficiency and lifespan.

Another challenge is efficiency. Solar Atmosphere to Water Generators are not yet as efficient as other methods of water production, such as desalination. However, due to the fact is essentially a passive system with very little maintenance and low cost, the efficiency of Solar Atmosphere to Water Generators is not as important as other types, and of course, the cost is expected to improve as the technology is developed further.

Despite these challenges, Solar Atmosphere to Water Generators have the potential to make a significant contribution to solving the global water crisis. With continued research and development, they could become a major water source for agriculture in arid environments.

Sustainable Mushroom Coffins – Human Compost

Sustainable Mushroom Coffins – Human Compost

Sustainable Mushroom Coffins

Mushroom coffins are made from mycelium, the vegetative part of fungi. The mycelium is grown around a mold of the desired shape and then dried, forming a sturdy, biodegradable material that can be used as an alternative to traditional coffins. These coffins are available in various shapes and sizes and can even be customized to suit individual preferences.

The coffin is designed to decompose quickly and enrich the soil. When buried, the mycelium in the coffin will break down organic matter, including human remains, into nutrients and minerals that nourish plants. It can also improve soil quality by breaking down toxic chemicals and pollutants in the soil, making it healthier for future growth.

 

Benefits Compared to Traditional Coffins

Reduced Carbon Emissions: Traditional coffins made of wood and metal are known to produce large amounts of carbon emissions during production and transportation. On the other hand, sustainable mushroom coffins are made of natural materials and require less energy to manufacture, resulting in lower carbon emissions.

Cost-effectiveness: Sustainable mushroom coffins are also more cost-effective than traditional coffins. While traditional coffins can be expensive due to the use of expensive materials and the cost of labour, mushroom coffins are much cheaper to produce, making them more affordable for families looking for sustainable alternatives.

Sustainable Use of Natural Resources: Sustainable mushroom coffins are also better for the environment because they utilize renewable natural resources and do not require harmful chemicals or pesticides to grow. Additionally, they help reduce the waste generated from traditional burial practices.

 

Composting Human Remains

Human compost is converting human remains, such as bones and tissue, into nutrient-rich soil using the same principles of composting used to fertilize gardens. It involves placing the body in a container filled with organic material like wood chips, straw, or sawdust. Oxygen and moisture encourage decomposition, resulting in nutrient-rich soil that nourishes plants.

Human compost is a more sustainable option than traditional burial and cremation practices. Traditional burial practices involve embalming fluids containing harmful chemicals that can seep into the soil and water supply. Conversely, cremation requires large amounts of energy to burn the body, which contributes to carbon emissions.

Human compost produces significantly less carbon emissions than traditional burial and cremation practices. Unlike cremation, human composting does not require high levels of energy use. Instead, the decomposition process occurs naturally, requiring only minimal energy input.

Human compost produces nutrient-rich soil that can be used to grow plants, trees, and other vegetation. This helps to replenish the soil and promote healthy plant growth.

The use of compost from human remains also helps prevent soil erosion. This is because compost has properties that help to retain moisture and reduce runoff, which can help prevent soil erosion.

If you are interested in using sustainable death practices like sustainable mushroom coffins and human compost, it is important to research and find a provider that offers these options in your jurisdiction. Discussing these options with your loved ones is also important so that your wishes can be honoured when the time comes.

While death is a reality for all of us, we can still make choices that positively impact the environment even after we are gone. By choosing sustainable death practices, we can make a more meaningful contribution to the planet, leaving behind a legacy of environmental consciousness and stewardship.
