For all of the grossness associated with sweating, it’s a vital function for dealing with hot climates. As perspiration evaporates or is hit by a breeze, the skin is cooled. Designer Benjamin Helle took that simple concept and applied it to a new kind of water bottle, made for cyclists. Read more
We are fans of creative DIY designs for gadget charging and lighting. So of course we were drawn to this entry in the Instructables Green Design contest for creating a simple thermoelectric emergency generator for an LED light (or possibly other gadgets) using just a handful of parts. It is not only a neat project for creating an emergency light but also an excellent project for kids learning about science.
From the project: “I´m using a thermoelectic module, also called peltier element, TEC or TEG. You have one hot side and one cold. The temperature difference in the module will start producing electricity. The physical concept when you use it as a generator it’s called the Seebeck effect. Read more
“It doesn’t look like a relaxing swim in the warm waters of the Bahamas. But for Vincent Canabal it is all in a days work when it comes to feeding his favourite a 16-foot long Tiger shark Emma.

The seas off the islands are home to Tiger Sharks, Lemon Sharks, Caribbean Reef Sharks, Nurse Sharks, Hammerheads and more”. Barcroft Media via The Daily Mirror Read more
The terrible pun in the title is courtesy of Gizmag, where I learned about this device. Most serious water filters need serious pumping or squeezing or sucking as they try to force the water and all the gunk in it through a relatively small filter.
The Grayl works like a French press coffee maker, increasing the surface area of the filter to the size of the cup, reducing the pressure required significantly. It is one of those ideas that make so much sense. Read more
