Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
Southern Alberta has seen some of the most exceptional drought in the country over the last few months — so it's no surprise that these conditions can possibly lead to dry and sensitive skin. This is especially so for newcomers to the province, like University of Calgary graduate Elisha Banerjee. "I was used to the cold, that was the part that was easy, it was the dry that I was not prepared for," she said.
Water is often the most crucial factor in controlling crop yields. The amount of water used by crops can be affected by several factors including the availability of stored soil water, amount of precipitation during the growing season, crop rooting depth and various environmental aspects such as day length, amount of solar radiation, humidity, temperature and wind.
EnerDynamic Hybrid Technologies (TSXV: EHT) has completed its first solar mobile system under its previously announced joint venture with Cinergex Solutions. The system, which is to be sold under the Solastream label, is an “air to water” solar mobile system. The machine itself uses patented technology that uses humidity to draw water from the air as a sustainable water solution. The tech when deployed effectively allows for fresh drinking water to be extracted from the air, enabling water security for its users.
On the ISS, every drop of moisture, from humidity to urine, has to be filtered and reused. But the current system is very heavy, has to be replaced every 90 days, and fails to filter out certain contaminants, according to NASA. Danish company Aquaporin A/S has developed a new system that uses proteins called aquaporins. "It is essentially the mechanism that allows water to cross the cell membrane of living cells," says Peter Holme Jensen, CEO of Aquaporin A/S. In nature, these proteins allow plant roots to absorb water from soil, and let the two human kidneys together filter about 45 gallons of fluid per day. They are also very selective, preventing contaminants from passing through.
