Children from poor families in sub-Saharan Africa have been able to swap cleaning up cowpats for lessons thanks to a solar power project that rewards parents for sending them to school. South Korean solar firm Yolk has designed a cow-shaped solar power station for schools that can be used to charge power banks for families while their children are in class.
The design references the fact that many children are removed from school in order to care for their family's cattle. "The kids could not come to school because of the cows and now they can come to school because of a cow - but it's a solar cow," SungUn Chang, the chief executive of Yolk, told the Thomson Reuters Foundation.
About 262 million children between the ages of 6 and 17 - or one out of every five globally - do not attend school, according to data from the United Nations education body UNESCO, which said access to education was largely shaped by wealth. Many poor families require children to stay at home and help with household tasks.
"The parent is the key man - so all of this is about how we persuade parents to send their kids to school," said Chang. She began researching how the company could help tackle child labour and said she quickly realised they had to offer a "tangible" incentive to families.
"If the value is similar or more, then they're wiling to send their children to school rather than the workplace," she said. As a solar company, energy was an obvious solution - and power is also an expensive commodity in developing countries. Many rural homes are not connected to the grid, meaning that households may have to walk several hours to reach a charging shop and pay to charge devices such as phones.
'Solar cow' charging stations are installed in schools and pupils are given a milk-bottle-shaped power bank which they plug into to charge if they attend class and take home at the end of the school day to provide households with electricity.
