New Nanofiber/Nanotube Material Filters Radioactive Contaminated Water

A new innovation from Professor Huai-Yong Zhu at Queensland's University of Technology can clean up all the water contaminated by radioactive materials. The material...

New Photo-Catalytic Fuel Cell Can Both Clean Wastewater and Produce Electricity

People have so far created many water purifying devices and we always presented them here on The Green Optimistic. Now, Yanbiao Liu and his...

Big Spring Town, TX, Recycles Urine For Drinking Purposes

Maybe inspired by The Adventures of Bear Grylls, some people in Texas started to recycle urine in order to fight drought. Big Spring, a town...

Homemade Water Distiller Built in Less Than an Hour

Here is a simple but efficient homemade water distiller that should be able to help us meet our daily water needs. As one of the...

Aquacube Water Treatment System Provides Clean Water in Underdeveloped Countries

Water, a key element of life, has always been one of the most exploited natural resources. Even if we have a lot of water (71 percent of the earth’s surface), in some places on earth drinking water still remains an unsolved issue. Especially with the increasing population and industrial development, our clean water resources dropped drastically in recent years.

NASA Forward Osmosis Bag Transforms Urine Into Drinking Water

If you ever saw Bear Grylls and his gross pee-drinking desert adventure, then you know you shouldn't drink that liquid (mostly when it's hot like soup and stinks like nothing else on Earth). NASA has nevertheless discovered a solution to this "problem" by inventing a bag that filters anything, from pee to dirty water and transforms it into a drinkable liquid.

New Graphite-Coated "Super Sand" Filters Water Much More Efficiently

With much of the world still lacking access to safe drinking water, the need for more efficient filtration systems is higher than ever. Wei Gao, from Rice University in Texas, has however invented a graphite-coated type of sand that is cheap to produce and much more effective at filtering water.

New Aluminum Alloy Helps Generate Clean Water and Cheap Electricity

A new aluminum alloy could soon clean out water and at the same time generate electricity for afflicted areas. Purdue University researchers Jerry Woodall and Go Choi have been working on the alloy of aluminum, gallium, indium and tin that could split polluted or salt water into hydrogen and oxygen and then reunite them to generate electricity and pure water.

Clean Water Harvested From Fog by Beetle-Inspired Device

Inspired by Stenocara gracilipes, a beetle found in the Namib Desert, MIT engineer Shreerang Chhatre developed a simple and efficient device that can harvest fog. Being actually an inexpensive way to provide clean drinking water, this fog harvesting device could be perfect for poorer countries, where water scarcity is still an unsolved problem.

Drinkable Water Extracted From Diesel Fuel Now Possible

Apparently, necessity teaches us better than any ecological drive, or at least this seems to be the case for the U.S. military. Missions can't do without water, but the amounts they need are very hard to transport. So the Oak Ridge National Laboratory has found a way to ease the pain of carrying large water supplies.
