Comments Off on Rebuilding for resilience — lessons from Puerto Rico and beyond

Over the course of just a few hours, Hurricane Maria exposed how fragile Puerto Rico is. Years of underinvestment in infrastructure and the recent financial crisis let the island languish, making the devastation far worse than it would have been otherwise. The storm caused the island’s entire electric grid to fail, its network of roads and highways to be disrupted, and access to clean drinking water lost. With no shortage of ideas on how to rebuild using better, stronger and cleaner technologies, who decides what gets built? How will it all be financed?

Comments Off on MIT: For Clean Drinking Water, All You Need is a Stick

Pine photo from Shutterstock A new report by MIT researchers suggests that if you run out of drinking water in the woods, all you need to do is to break off a branch from the nearest pine tree . Next pour lake water through the branch and this low-tech filtration system can produce up to four liters of drinking water a day. A small piece of sapwood is reportedly able to filter out more than 99% of the bacteria E. coli due to the size of the pores in the xylem tissue.

Comments Off on Portable Solar Power Plant, Water Purifier and Fuel Cell in One

In many areas of the world, and also during times of natural disasters, clean drinking water and access to power are scarce.  The company The Essential Element has designed the Hydra water purifier and fuel cell to take care of both of those problems at once. The Hydra is equipped with a 2.88 kW solar panel array that runs a pump that pushes water through a self-cleaning filtration device (capable of purifying 87,000 liters a day), juices up lead-acid gel batteries and runs an electrolyzer that splits some of that water to fill a .37 cubic-meter tank with pressurized hydrogen
