Student-built solar motorbikes hit the road in Kenya

Motorcycle taxi operators waiting for passengers in this village in western Kenya’s Kisumu County lounge on their various machines – but Alfred Omondi’s plug-in electric scooter stands out from the crowd.

Surrounded by motorbikes running on polluting fossil fuels, Omondi sits astride his solar-powered rechargeable motorcycle, which uses technology developed by students from the University of Nairobi.

Charles Ogingo, Robert Achoge and James Ogola – all final year students – have built a system they call Ecotran, which captures the sun’s energy, stores it in batteries, and uses it to charge a motorcycle’s electric motor.

Much of western Kenya has no grid electricity, and the places that do face frequent power disruptions, so solar energy is a promising alternative, they say.

The three students have set up a “fuelling” station with 40 solar photovoltaic units, each generating 250 watts of electricity. The energy is stored in batteries before being transformed by powerful inverters into the alternating current needed by the motorcycle.

The motorbike uses a small portable battery which, fully charged, can run for 70 kilometers (40 miles), after which it must return to the station to be recharged while another charged battery is fitted to the bike.

The students, who have set up a company called Pfoofy Solar Ltd, put together their system in 2014 at a climate change innovation center at Strathmore Business School in Nairobi, where they had been sent to give practical form to their ideas.

After successfully trying out the Ecotran technology on three locally bought motorcycles in Kisumu County’s Nyakach area early this year, the young innovators are now expanding the project, and powering 40 more bikes.

“We were awarded $100,000 by the United States African Development Fund and Power Africa for the ingenious innovation. It is this money that we are now using to upscale the solar project,” said Pfoofy Solar manager Achoge.

The new motorcycles are imported from China, he said.

Illness and deaths linked to air pollution cause economic losses of $15 million a year, according to a 2014 study in Nairobi by the University of Nairobi. In Kenya, 39 percent of air pollution is caused by motor traffic, the study said.

The motor industry is the main source of air pollution in Africa, and air pollution causes an estimated 176,000 premature deaths a year on the continent, according to a World Health Organization survey of 2012.

  1. Thanks for sharing Student-built solar motorbikes hit the road in Kenya. I think these type of bike really helpful for going green. .

  2. These type of skills really help for the growth of students. Government must take step to promote the technical courses so that they got talent from their country.

  4. Great to see such results in students study! Sadly not many of student inventions get enough attention. As well as not enough student care about making any real contribution to science and ecology…

  5. So weird. I was just searching for information about this stuff and you popped up. You must be doing something right. Thanks by the way, this really answered some questions I was throwing around in the back of my mind.
