With the rising concerns about clean, fresh and drinkable water for all, it's no surprise that inventions utilizing the most bleeding edge of technology are starting to crop up as potential resources for the water crises. It is important to state, flat out, that it is highly likely that any one technology will prove a true solution. Resolving the crisis will take a multi-pronged approach that relies on changing human behavior, technology, as well as rules and strictures on water usage. That said, invention certainly has its place.
|Water From Sludge|
Michael Pritchard has invented a bottle that turns fetid, murky water into clean, potable water through the clever use of filters. The Lifesaver bottle is a simple enough design but only possible through cutting edge tech.
How does it work?
"The smallest bacteria are about 200 nanometres in diameter while the smallest viruses are 25 nanometres. The holes in the membranes used by Lifesaver are 15 nanometres wide, blocking bacteria, viruses, cysts and waterborne pathogens from getting through. Dirty water can can be left in the unit until it needs to be cleaned.
The cartridge in the bottle is replaced after through-put of 4,000 or 6,000 litres, while the jerry can lasts for between 10,000 and 20,000 litres. Towards the end of the life of the unit, more pumps are needed. When the pumps no longer work, the filters have to be replaced."
