Loyal readers of my blog know I am a big fan of technological inventions that shine in their simplicity and have a big impact at the same time. Among the many solutions that have been showcased earlier on The Shift, the Lifestraw is one of my favourites. Being cheap and simple, it can potentially save thousands if not millions of lives by providing clean drinking water in developing countries or regions hit by severe weather events. But… I have found a strong competitor: an off-grid portable refrigerator to stransport vaccins safely to the final destination in developing countries. And I am not the only one who seems to like it; recently its inventor received the prestigious UK James Dyson award.
