Floating wave-powered buoy makes desalinating seawater cheaper and eco-friendly
Desalination plants help to solve drinking water shortages. However, they need a lot of energy and they spit concentrated brine back into marine ecosystems. That’s why two engineers have created a floating wave-powered desalination buoy that performs reverse osmosis while bobbing in the sea to Read More...
A solar panel that pulls clean drinking water straight from the air
Every ten seconds someone in the world dies from a waterborne disease. That makes clean drinking water one of the most precious ingredients to sustain life. However, in many developing countries clean water is rare. That’s why the Source from Zero Mass Water is such great invention. It’s a Read More...
Ontario seeks to put a cap on water bottle industry with two-year ban
The Ontario government has proposed a two-year moratorium on the creation or expansion of bottled water operations fed by groundwater in the Canadian province, in a bid to strike a balance between a burgeoning bottled water industry, a growing population and the effects of climate change. The Read More...
Water purification pods designed to create a world without single-use water bottles
What if a reusable capsule could purify and freshen tap water? Bloc Enterprises’ PuriBloc GoPure water purification pods aim to help solve two problems: nasty tap water and expensive wasted plastic bottles. It’s a localized issue for sure, but many people can’t drink their Read More...
Is using less water the secret to cutting our greenhouse gas emissions?
When most of us think of slowing global warming, we think of reducing car exhaust and power plant emissions – limiting activities that involve combusting fossil fuels. But we rarely draw the connection between the production of energy and another important resource: water. Yet in California, Read More...
Harvesting water from air with solar: a sustainable drinking water solution?
The ability to harvest water from air is a technology that has existed for a long time, even going as far back as the Incas. But success in scaling up this technology has been elusive. The largest hurdle is that the technology is energy-intensive, making it cost-prohibitive with dubious results. Read More...
This wind-powered device could help bring water security to villages
Researchers have developed a wind-powered condenser that is able to provide 11 gallons of drinking water every day out of nothing but air. The device works as a high-tech artificial well, pulling air into a chamber buried below the ground where it condenses into water. Best of all is it runs Read More...
How to build a compost shower for free hot water
A heating system developed by a French innovator decades ago is gaining a new life as a sustainable way to get free hot showers in the modern world. The annual build of the compost shower has just been completed at the Fair Harvest Permaculture Farm in Margaret River WA. The system was developed by Read More...
How mobile banking brought water back to Nairobi's slums
In Kayole, a slum on the outskirts of Nairobi, Kenya, Joab Omondi has been selling water from a cart since the government connected his neighborhood to the local water system. Two years ago, water was a scarce commodity here. Residents used to have to hunt around to buy a 5-gallon can of water for Read More...
Scientists create coffee-infused foam that cleans water
The world runs on coffee, which means there’s a lot of used coffeegrounds. One way of making use of them is by incorporating spent coffee grounds in a foam filter that can remove harmful lead and mercury from water. Researchers recently fixed used coffee ground into a special foam, and they Read More...
