This lamp runs 8 hours on just a glass of seawater


Rural areas in the Philippines with no access to electricity depend on candles, kerosene lamps or battery operated lanterns as common household light sources. But aside from being costly and inefficient, they are also dangerous to use. Now, thanks to Engr. Aisa Mijeno, a lamp that is totally safe, environmentally-friendly, and capable of emitting light on just a glass of salt water will soon brighten up these communities.

   Aisa was inspired to design the SALt lamp (SALt is a contraction of Sustainable Alternative Living) after living with the natives of Kalinga's Butbut tribe for days relying only on kerosene lamps and moonlight to do evening chores.

   So how does it work? As simple as it sounds, the lamp uses a solution of one glass of water mixed with two tablespoons of salt to provide 8 hours of light. It will even run off seawater. Oh, and did I mention that you can also charge your smartphone or tablet from the lamp?

   The device uses the same science that forms the basis of battery-making. In a typical battery, two metal electrodes are dipped into an electrolyte solution. In this case, the electrolyte is salt water. The electrode in the SALt lamp can last up to a year, depending on how often and long it is used.

   Currently in the development stage, the people behind the product aim to have the lamps mass produced later in the year. However, their main priority right now is to deliver the SALt lamps to their target communities.

Photographer documents her stay at a mental hospital with haunting self-portraits

Most documentary projects about mental illness reveal someone else's behavior, but Laura Hospes took a very different approach. The Dutch photographer documented her stay at a psychiatric ward, and her raw, striking and sometimes unbearable black and white self-portraits reveal the reality of what it's like to recover from anxiety, depression and eating disorder following a suicide attempt. The project, which Laura called UCP-UMCG, (named after the hospital in which she stayed) earned her a spot on LensCulture's list of 50 best emerging photographers for 2015 in the LensCulture Emerging Talent Awards. One picture shows her staring blankly ahead while clad in a sleeveless shirt. In another, she is depicted lying on a bed, half naked. "At first, I made this complete series for myself, to deal with the difficulties and express my feelings,” she told The Mighty . "After that, I want to inspire people who are or have been in a psychiatric hospital. I want them to s...

Print out and fold your own paper cameras

Totally want to make some of these Olympus mirrorless cameras with my daughter this weekend. They don't take pictures, but they sure would make my little girl very happy. The Japanese company has a webpage for kids , and you can easily create three-dimensional paper models of the OM-D or the PEN Lite by printing and folding those PDF templates in the papercraft section . Enjoy! [h/t: Pop Photo ]

The Adorable Sculptures of Yen Yen Lo

These images are from a series of wall sculptures created by Yen Yen Lo . Here you can see her intricately textured ceramic pieces, looking downright adorable. Yen Yen Lo's eye for the unique and whimsical is delightful. Apparently they are not intended for kids under 16. Fifteen-year-olds cannot be trusted with fragile stuff. Get them a Funko Pop instead.
