Salamander Research And Development's latest idea concerns the worldwide demand for potable water.
Most distillation devices require replaceable filters or sophisticated wiring or plumbing. My device is scalable from 1/2 liter on up; it can be made from clean scraps and it (in the small volume ranges) is entirely portable. This allows you to move it to the to-be-distilled water source.
The original power source for the needed heat is the Sun, although if weather does not cooperate, you can build a small fire underneath the metal support frame. A Fresnel lens directs the heat onto the container to promote evaporation which is then collected in a clean vessel.
