Texas teenager creates $20 water purifier to tackle toxic e-waste pollution

18-year-old Perry Alagappan recognised at World Water Week 2015 for his renewable heavy metal filter made from graphene that he’s keeping open source

Now a new filtering device, invented by a US teenager, could provide a cheap and easy way to purify water.

The renewable heavy metal filter, designed by 18-year-old Perry Alagappan, removes 99% of heavy metals from water that passes through it. The filter, built from graphene nanotubes, can be rinsed with a vinegar concentrate and reused. The highly concentrated waste can then be evaporated, leaving a deposit of pure metal that can be used in many different applications.

Alagappan, who was awarded the Stockholm Junior Water Prize at this year’sWorld Water Week, said the filter cost just $20 (£13) to make, up to five times less than existing reverse osmosis technology.

“I became interested in water purification when I visited my grandparents in India, and saw with my own eyes how electronic waste severely contaminated the environment,” said the recent high school graduate from Houston, Texas, on winning the prize.

Paint job transforms walls into sensors, interactive surfaces

Smart walls react to human touch, sense activity in room

Walls are what they are – big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used.

Researchers at Carnegie Mellon University and Disney Research found that they could transform dumb walls into smart walls at relatively low cost – about $20 per square meter – using simple tools and techniques, such as a paint roller.

These new capabilities might enable users to place or move light switches or other controls anywhere on a wall that’s most convenient, or to control videogames by using gestures. By monitoring activity in the room, this system could adjust light levels when a TV is turned on or alert a user in another location when a laundry machine or electric kettle turns off.

“Walls are usually the largest surface area in a room, yet we don’t make much use of them other than to separate spaces, and perhaps hold up pictures and shelves,” said Chris Harrison, assistant professor in CMU’s Human-Computer Interaction Institute (HCII). “As the internet of things and ubiquitous computing become reality, it is tempting to think that walls can become active parts of our living and work environments.”

When life gives you lemons, make lemonade, right? That, at least, is the motto the European Space Agency seems to have embraced with respect to two wayward satellites, which are being repurposed to provide the most accurate assessment yet of how gravity affects the passage of time.

Welcome to a three part series of kitchen appliance design using unconventional and sustainable materials. 

Part one of the series is a toaster designed using steam-bent bamboo plywood, glass toasting trays, a 2″x1″ touchscreen and quick-cooling coils embedded within the glass toasting trays. Gone is the bizarre popup mechanisms of toaster’s past – the toaster features wide, easy access slots. The heating coils feature quick-cooling technology and the UI tells the user when its safe to grab their toasty treats. Bamboo and glass are both sustainable and renewable and the design uses no plastic and minimal metal.

Michelle Obama launches #62MillionGirls to fight for girls’ education

Michelle Obama has unveiled a new campaign focusing on the tens of millions of girls around the world who lack access to any kind of education. "Right now, 62 million girls are not in school,“ the first lady told the Global Citizens Festival. “And what’s important to know is that these are our girls. They deserve the same chances to get an education as my daughters and your daughters and all of our children.“ Celebrities, politicians and other Twitter users were quick to jump on the hashtag.

Anyone who believes exponential growth can go on forever in a finite world is either a madman or an economist.
