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.

Weirdly Charming

If you’re a fan of art that makes you do a double-take, you need to check out  Richard Brener . Based in the UK, Richard is an internationally collected artist who works primarily with ink, fineliners, and gouache. When you first see his pieces, they actually look pretty playful. Then you realize the entire canvas is packed with thousands of tiny, ghost-like shapes he calls "champs." They’re all squeezed together like commuters on a rush-hour train, and the level of detail is honestly mind-blowing. Richard spends hundreds of hours drawing these little guys over and over. It’s obsessive, very intentional, and a little bit wild. The cool part is that the longer you stare, the more the vibe shifts. Check out more photos below:

Stone horsemen invade River Thames

It's not uncommon to see huge art installations on River Thames: a giant fiberglass sperm whale , a floating house , a massive wooden hippo . If you happen to be in London, head down to Nine Elms, on the south bank of the waterway, any day this month, and — if it's a low tide — you'll see a group of stone horsemen by world-renowned underwater sculptor Jason deCaires Taylor , rising above the riverside beach. The artwork, titled The Rising Tide , is part of the Totally Thames arts festival and is the first of its kind to be installed in the famed river. Four three-meter tall working horses with riders are shown — two of the riders are businessmen and two are children — though horse heads have been replaced with oil pumps. The sculptures are on display until the end of September.
