A Urine Powered Generator : Maker Faire Africa Posted on Tuesday, November 6, 2012 · 168 Comments Possibly one of the more unexpected products at Maker Faire Africa this year in Lagos is a urine powered generator, created by four girls. The girls are Duro-Aina Adebola (14), Akindele Abiola (14), Faleke Oluwatoyin (14) and Bello Eniola (15). 1 Liter of urine gives you 6 hours of electricity. The system works like this: Urine is put into an electrolytic cell, which separates out the hydrogen. 15-Year-Old Develops Hollow Flashlight Powered by Body Heat From a sleeping bag that charges your gadgets to entire buildings warmed by body heat, scientists are harvesting the heat emitted by humans as a source of renewable energy. But the latest development in thermoelectric energy generation doesn’t come from a high-tech lab at MIT; it comes from Ann Makosinski, a 15-year-old Canadian girl who developed a flashlight that is powered by the heat from a human hand. With the aim of reducing the number of single-use batteries that are thrown in landfills, Makosinski developed the innovative flashlight, which can be developed cheaply and deployed to populations that can’t afford electricity to light their homes.
20 Stunning Photos Of Natural Beauty That Your Human Eyes Could Never See The winning photos of Nikon's annual Small World Photomicrography Competition prove that there is really more than meets the human eye. The 20 winning photographers this year are masters of photomicrography, or photos taken through a microscope. Each photo is an example of the wondrous beauty and detail that can be found in the most unexpected things, like plankton and embryos. The first place winner, Wim van Egmond, explains how he takes photos: "I approach micrographs as if they are portraits. The same way you look at a person and try to capture their personality, I observe an organism and try to capture it as honestly and realistically as possible."

GSF 2013 : Project : Going Bananas!-Using Banana Peels in the Production of Bio-Plastic As A Replacement of the Traditional Petroleum Based Plastic The banana fruit’s peel was selected for this experiment because it is a waste material rich of starch-according to Songklanakarin Journal of Science and Technology, the proximate composition of a banana peel is shown below. Items Content (g/100 g dry matter) Protein: 8.6±0.1 Fat: 13.1±0.2 Starch: 12.78±0.9 Ash: 15.25±0.1 Student finds new way of turning plastic into biofuel [CAIRO] A method for generating biofuel by breaking down plastics using a low-cost catalyst will be developed further in the United Kingdom next month (16 July). The process was developed by a sixteen-year-old Egyptian student, Azza Abdel Hamid Faiad, from the Zahran Language School in Alexandria, Egypt. Faiad won the European Fusion Development Agreement award at the 23rd European Union Contest for Young Scientists — involving 130 competitors from 37 countries — held in Finland last year (23–28 September).
7 Incredible Inventions by Teenage Wunderkinds When many of us were in our teens, work for science fairs comprised cut and paste displays on colorful presentation boards, and our hobbies weren't exactly about to change the world. But across the globe, teenagers with creative, scientific minds are already devising extraordinary devices, revolutionary materials and renewable technologies that might just change our planet for the greener. Click through to see some of their most incredible inventions - from bioplastics made from bananas to pee-powered energy generators and an ocean cleanup array to rid the world's oceans of waste.

Electromagnetic Radiation – The Dark side of Technology In our daily lives we are constantly exposed to powerful electromagnetic fields or EMF emitted from cell phone towers, wi-fi hubs, high voltage wires, common devices like televisions, microwave ovens and almost all electronic appliances. These EMFs have shown to disturb the human body’s natural energetic field, so you will experience the effects of it on a biological level in the body. In simple terms, electromagnetic fields are invisible waves that emanate from any electrical or wireless device. Its a kind of radiofrequency EMFs (RF-EMFs) by which all wireless technology operates. Since the field possesses magnetic and electrical properties, it also interacts with charged objects within the field (The human body possesses a positive field).
