As we approach the fifth anniversary of the Deepwater Horizon oil spill, scientists are still trying to develop better ways of removing oil from water. Now, researchers at The Ohio State University believe that they may be onto something. They've developed a stainless steel mesh that allows water to pass through, but that stops oil.  Read More

Cigarette ash could now have another use besides ... well, nothing (Photo: Shutterstock)

In a perfect world, cigarette waste simply wouldn't exist. Given that it does, though, scientists have explored a number of methods of repurposing it – these have included using compounds from cigarette butts to store energy, make shipping pallets, and rust-proof steel. Now, researchers have shown that cigarette ash can be used as a low-cost means of filtering arsenic from water supplies. It's a little ironic, as cigarette smoke actually contains a dangerous amount of arsenic.  Read More

It's no secret that hundreds of millions of people around the world have little or no access to drinkable water. While a number of projects are aimed at getting filtration systems to those people, many of those systems require electricity, contain costly materials such as silver, or treat the water at a slow rate. The low-cost DrinkPure filter, by contrast, is simply screwed onto the top of an existing bottle, and can purify approximately one liter (34 fl oz) of water per minute.  Read More

The ÖKO Odyssey six-in-one water bottle/light

Most water drinkers are satisfied if their bottle does its single function – holding water for the occasional sip – effectively. Occasionally, an H20 aficionado is spoiled by two bottle functions, something like a built-in UV purifier or lantern. The new ÖKO Odyssey water bottle, on the other hand, blows bottle expectations up with six functions, including two filters, a flashlight, a lantern and a storage compartment. It's much more than just water.  Read More

In many parts of the world, the presence of harmful bacteria makes it vitally important that water from lakes or rivers be thoroughly filtered before being consumed. While materials such as silver nanoparticles and titanium dioxide will do the job, people in developing nations or rural settings typically need something a lot cheaper and easier to manufacture. As it turns out, wood from pine trees works great.  Read More

The nkd AQUA POD is claimed to replicate water sourced from mountain springs

Companies such as Vapur and Camelbak tout the health and environmental benefits of their water bottles over bottled water. NKD Aqua toes that line but targets the luxury bottled water market by claiming its Pod replicates mountain spring water.  Read More
