I believe that you will have gathered by now that I’m a pretty huge proponent of The Africa Trust. I may blather on about it, but please, pick one of numerous reasons, not in the least the fact that thanks an incredibly hard working team, potable water is brought to millions of people in the world and you’ll have really clear idea of why I’m such an enthusiast.

With this in mind, I’m constantly on the look out for discoveries / inventions that can make the world a better place for all involved. Ways that draw from nature, science, ways that are practical, sustainable and more often than not, pure genius.

*Open-Source, Personal Water Desalinator: Italy

Briefly, Eliodomestico is an eco-distiller that uses solar power to make salt water drinkable. Created by Italian designer Gabriele Diamanti, Eliodomestico is an open-source project designed to provide safe drinking water for people in developing countries. Essentially, the device works like an upside-down coffee maker to produce five litres of fresh water every day. Users begin by adding sea water in the morning. Over the course of the day, the heat of the sun causes steam to rise into a water-tight boiler. The steam is then forced down through an expansion nozzle and condenses against the lid of a collection basin. At the end of the day, users can remove the basin, which is full of fresh water and designed for transport on the head.

Eliodomestico is made from widely available materials and requires no electricity or filters; maintenance is simple, Diamanti says.

Gravity-Powered Lamp: United Kingdom

Many of us may take electric lights for granted, but there is a considerable portion of the world—around 1.5 billion people—that lives in poor, remote areas and has to rely on dangerous kerosene alternatives. Currently being funded through an Indiegogo campaign, the GravityLight hopes to change that by offering a cheap lamp that runs on a renewable resource. The device is attached to a weight, which when lifted for a few seconds harnesses enough energy to power the light for 30 minutes. Operating without batteries, the GravityLight contains no deteriorating parts and means owners don’t have to spend money to keep it running.

How fabulous are those? Pretty fabulous I say.
