A User-friendly And Energy-efficient Device That Generates Clean Drinking Water With The Push Of One Button

Image
Researchers at the Massachusetts Institute of Technology (MIT), U.S., have invented a portable desalination unit, weighing less than 10 kilograms, that can remove salts and impurities from the seawater to generate clean and clear drinking water. Image Credits: Pixabay The portable desalination unit is a suitcase-sized, user-friendly device that requires less power to operate, can be driven by a small portable solar panel and runs with the push of one button. This device generates clean drinking water without using any filters or high-pressure pumps. The water obtained exceeds the World Health Organisation (WHO) quality standards. Unlike other desalination devices, it consumes less energy to discard impurities from water and reduces the long term maintenance requirements. This could enable the device to be deployed in remote areas such as communities on small islands. It could also be used to aid refugees or by soldiers carrying out long-term military operations. “This is really the c

How safe is your fridge bottle?

In our day-to-day lives, we exercise extreme caution when it comes to drinking water. Water is treated at multiple points before it reaches your tap and even at home, we tend to use water purifiers that promise to kill 99.99% bacteria, viruses(?) and any other pathogen that might infect you. But have you ever wondered, how safe is the bottle that we store the water in? Multiple studies conducted have shown that the regular colourful fridge bottles, often made from polycarbonate (marked with a recycling code , 7) leaches Bisphenol A (BPA) into the water. BPA is the monomer that makes the polycarbonate plastic and hot or warm fluids usually result in depolymerization and release of BPA. This released chemical is very similar to estrogen and is capable of copying its function too. The Tolerable Daily Intake for BPA is 0.05 mg per kilogram of body weight per day. While this might be huge as compared to how much BPA actually leaches out, BPA has been associated with breast a
