'what a neat idea' department,
it is also a life saver, but what is it? I hear you ask, it began in Australia as an idea of Petra Wadstrom, (born 1952 in Stockholm, Sweden) who is the inventor and founder of SOLVATTEN, in the late 1990s Carl Wadstrom, Petra’s husband, a medical doctor specialised in surgery, oncology and the treatment of cancer, was assigned a position at the Royal North Shore Hospital in Sydney, Australia, living in Australia with an abundance of sunshine made Petra use her creative mind in new ways, pondering possible ideas to use all that sunshine in some way that would improve poor peoples lives, She was especially interested in creating a solar harnessing device that would first and foremost make the hard lives of many women in poor countries better,
and what better way to help save lives than making a product that would make safe drinking water? just open the Solvatten add unsafe water and let the sun do the rest, an indicator shows when the water is safe to drink, keep the device open and the water will continue to heat up, providing hot water (up to 75°C) suitable for a wide range of domestic purposes, designed to provide the daily need for safe, warm water of a family (5-6 persons), no batteries, chemicals or spare parts are required, it also it means that wood normally needed to heat and sterilise water is no longer needed, as I said before, what a neat and potentiality life saving idea.
