While many of us may enjoy grilling food over an open fire, the fact is that cooking fires are a major source of health problems for millions of people in developing nations, who use them on a daily basis. The main problem is the smoke, which causes respiratory problems – not to mention air pollution. In an effort to address the problem, research group RTI International has developed a cook stove that burns cleaner … and that powers gadgets.
For people in developing nations or rural locations, getting clean water may soon be as simple as opening a book … and ripping a page out. That’s the idea behind The Drinkable Book, developed by Carnegie Mellon University postdoc Theresa Dankovich. Each of its pages is made from a thick sheet of paper impregnated with silver and copper nanoparticles, that kill 99.9 percent of microbes in tainted water that’s filtered through it.
Whether it’s slides at playgrounds or roofs of houses, there are some things that you just don’t want to heat up in the sun. Not only does it make them uncomfortable to touch, but it also causes them to age prematurely. While painting such surfaces white is one approach, a scientist at Johns Hopkins University has developed another – reflective paint made from glass.
Amputees in developing nations frequently can't afford the high-end
prostheses used by people in other parts of the world. That's why
Technological University of Mexico spin-off company Protesta is
developing a low-cost artificial arm made from lightweight polyethylene
terephthalate (PET) plastic. As an added bonus, the arm will alert the
user if it gets too hot.
Lying somewhere between an exhibition of school science projects and a presentation of company R&D concepts, Maker Faires provide a window into a world of ingenuity and creativity where talented "hands-on" types let their imaginations run wild. So what did Maker Faire Tokyo 2015 have in store? Gizmag dropped by to find out.
If you've ever been on your sofa and wondered how long you might have to queue for a bike at the gym or how long the wait is for a table at your favorite restaurant, then the Density sensor could provide the answer. Designed to be attached to the entrance of a premises, the sensor captures people's comings and goings to provide real-time and historical data about the volume of traffic passing through.
UK supermarket Tesco says it will update the voice and phrases of its self-service checkouts. This, in itself, is nothing notable, but the reasoning behind it tilts at a broader issue: how we expect computers and robots to address us. Tesco's opinion? We don't want them bossing us around.
While city dwellers may be used to railway crossings marked with
flashing red lights, the easier-to-miss warnings at rural crossings
often just consist of a sign. That's because there's no easy way of
providing electricity to such isolated locations. While solar panels
could provide part of the solution, a team of engineering students and
faculty at the University of Nebraska-Lincoln believe that photovoltaics
alone can't consistently provide enough power. Instead, they devised
several systems that harness power from the rails themselves.
Here's a neat idea from a young designer based in Bath, England. The BATH °C Thermo Colour Map offers a new take on the tourist map by highlighting certain areas of the city that are most suitable to visit, depending on the weather.
We already know that cardboard isn't just for packaging, but US company Ernest Packaging Solutions recently pushed the envelope to create a cardboard skateboard deck. The deck was put through its paces by pro-skating legend Tony Hawk.
