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.
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.
An underground irrigation technology has helped 100 farmers in Tunisia to continue farming in times of droughts. Dubbed the Buried Diffuser, the technology utilizes 2 times less irrigation water than drip irrigation, while raising yields 3 to 5 times more; and ensuring water is not lost through evaporation.
A new open source grain drying technology dubbed the EasyDry M500, has been developed in East Africa, to help small holder farmers dry grains effectively and quickly, to reduce post harvest losses. The portable dryer, dries 500 kilograms of maize in 3 hours, by lowering the moisture content from 20 to 13.5 percent, the recommended moisture content level, for maize storage.
Three young innovators in Kenya have developed an award winning technology that harvests clean drinking water from the air, targeted at rural communities living in dry regions, and communities in urban areas lacking access to clean water. The innovation dubbed Majik Water is powered by solar energy and utilizes sponge like non toxic desiccant materials to generate water from the air.
