Three African countries are piloting the use of a 3 and 4 wheeled bikes powered by solar energy. Dubbed the Solar E Cycles, the bikes are fitted with solar panels that tap the sun’s energy and charge the batteries during the day. The energy stored in the batteries powers the vehicle for a distance of up to 50 kilometers a day, at a maximum speed of 35 kilometers per hour, before a recharge is needed.
Cleaning chemicals can trigger allergies and asthma in some people. This is because they contain substances such as chlorine, formaldehyde, perchloroethylene and chemicals found in “fragrance”. Instead of chemical cleaning products, you can make your own at home using such things as baking soda, vinegar and lemon juice.
At least one in ten girls in Sub-Saharan Africa misses school during their menstrual cycle. So, women suffer a lot from this situation, and it affects most of them in the rural area who cannot go to school or afraid to do any other type of work in public during the menstruation period and are forced to isolate themselves. A way to combat this has been using the agricultural waste from banana trunk fibres which is a cost-effective way to make sanitary products.
More than 8 million people don’t have access to clean drinking water the world over; and more than 2 billion get their water from contaminated sources. Despite this problem, emerging technologies including solar powered purification systems are making it possible for emerging ecnomies to achieve cleaner drinking water.
Three young inventors from New Delhi, India have developed Chakr Shield; a technology that traps over 90 percent of pollutant suspended particulate matter (SPM) emissions from exhaust pipes of diesel generators. The SPM in form of soot (black carbon) is then recycled to make inks and paints.
It is estimated that 844 million people lack access to a clean drinking water service, 2 billion people drink water from a contaminated water source. Each year this leads to an estimated death rate of 502.000 people. Producing clean water is a very intense process that requires a considerable amount of energy and efficient technology to run the water purification process.
When I was young, like most children in developing countries, never had a chance or dreamed of using a microscope in primary school, even in high school microscope usage was rare yet I was studying science. This is a major challenge for the scientific schools students and lowers the science knowledge transfer. This challenge is not just because the governments are not doing anything but to have enough scientific infrastructure is very expensive. It has an impressive magnification lens up to 140x and weighs just 8 grams.
The World Health Organization (WHO) estimates that around 150,000 annual deaths in low-income countries are brought about by the adverse effects of climate change. It’s time to open our eyes and realize that overall health concerns are greatly affected by the world around us and it’s time for serious positive action.
In Kenya 17.3 million people lack access to clean water with water borne diseases like diarrhea and Cholera being the leading cause of death for children under five years. But a group of women have found a low cost method of purifying water, which is now backed by science - embracing seeds from the wonder tree Moringa oleifera.
Zipline, a robotics company based in California, recently launched the use of medical drones to transport bloods to remote hospitals in the Western province of Rwanda, that have challenges with lack of proper infrastructure and quick access to medical supplies. The launch at Kabgayi hospital, in the Southern Province of Rwanda was in the presence of HE Paul Kagame, the President of Rwanda.
