A team of students from Strathmore University in Nairobi, Kenya on Thursday walked off as winners with R20 000 in prize money for an innovative concept to provide equitable energy access to remote villages based on, among others, “Uber(ising) solar energy.”
The team was one of four university teams participating in the African Utility Week and Powergen Africa conference and exhibition’s first ever Initiate! Impact Challenge. The 19th edition of the event gathered thousands of power, water and gas industry experts in Cape Town this week and ended on Thursday.
Student teams from Stellenbosch University, the University of Cape Town and the University of the Witwatersrand also took part in the three-day challenge sponsored by the Enel Foundation, the Innovation Hub, Lesedi Nuclear Services and the Russian Nuclear Agency Rosatom. The Initiate! Challenge aimed to create a platform for students and start-ups to drive innovation and share ideas for the energy sector.
The Strathmore University team included engineering students Ignatius Maranga, Raymond Kiyegga, Fredrick Amariati and Alex Osunga. One member of the team will also have the exclusive opportunity to join the 5th annual student fact-finding mission to Russia to visit several state-of-the-art nuclear facilities and dedicated Russian nuclear universities. Maranga said the team is happy and humbled especially because they competed against some of the top universities on the continent. He said the teams’ winning idea is rooted in real life challenges that Kenyans in rural areas face. “The solutions offered so far to expand energy access are not solving these problems as many are not financially viable.”
The team’s idea is to put a solar panelled container in rural villages that will also house a clinic and a knowledge hub like a school for vocational training to teach people about the use and benefits of solar energy. It will also include a shop where villagers can buy daily essentials like milk.
Maranga said: “The school will help with capacity building as villagers will see and learn benefits of electricity and as the business grows, they will want to have electricity in their homes and when that point comes, we will have solar powered tricycles. These tricycles will carry and deliver batteries like Uber does passengers to villagers in more remote areas. The system is modular so we will add another container to charge batteries. These batteries are ferried on trikes, so villagers in more remote areas can request a number of charged batteries on their phone.”
Maranga explained that it is common cause that Africa is big, and many people live in remote rural villages. “So, it is not always possible to extend the power grid to these areas as it is very expensive. So, what do we do instead? Most people own a cell phone, and everyone needs electricity, so you take it to them. They cannot exactly carry a battery for two kilometres so why then not Uber a battery?” Maranga said their company Kijiji, (Swahili for village) will now look at commercialising their idea, optimise it and do market tests. “If accepted we want to roll it out depending on funding.”
The team’s idea appealed to the judges because it was a simple idea that is easy to replicate beyond Kenya to the rest of the continent. Chief executive officer of Rosatom Central and Southern Africa, Dmitry Shornikov, said: “We are very pleased with the solutions presented by the students. The maturity and depth of their research gives us great hope and proves that young Africans really are devoted to solving Africa’s energy challenges.”
Business Development executive at Lesedi Nuclear Services, Shane Pereira, in an earlier interview said the company partnered with Initiate! because it is dedicated to the youth that will be the leaders of tomorrow. “The growth and development as well as training, coaching and mentoring of the youth is critical to the success of our future economy.”
The ideas of the other three teams focused more on mitigating the risk of climate change and came up with ideas ranging from vertical farms to energy boxes.
SA’s Internet goes down again
South Africa is about to experience a small repeat of the lower speeds and loss of Internet connectivity suffered in January, thanks to a new undersea cable break, writes BRYAN TURNER
Internet service provider Afrihost has notified customers that there are major outages across all South African Internet Service Providers (ISPs), as a result of a break in the WACS undersea cable between Portugal and England
The cause of the cable break along the cable is unclear. it marks the second major breakage event along the West African Internet sea cables this year, and comes at the worst possible time: as South Africans grow heavily dependent on their Internet connections during the COVID-19 lockdown.
As a result of the break, the use of international websites and services, which include VPNs (virtual private networks), may result in latency – decreased speeds and response times.
WACS runs from Yzerfontein in the Western Cape, up the West Coast of Africa, and terminates in the United Kingdom. It makes a stop in Portugal before it reaches the UK, and the breakage is reportedly somewhere between these two countries.
The cable is owned in portions by several companies, and the portion where the breakage has occurred belongs to Tata Communications.
The alternate routes are:
- SAT3, which runs from Melkbosstrand also in the Western Cape, up the West Coast and terminates in Portugal and Spain. This cable runs nearly parallel to WACS and has less Internet capacity than WACS.
- ACE (Africa Coast to Europe), which also runs up the West Coast.
- The SEACOM cable runs from South Africa, up the East Coast of Africa, terminating in both London and Dubai.
- The EASSy cable also runs from South Africa, up the East Coast, terminating in Sudan, from where it connects to other cables.
The routes most ISPs in South Africa use are WACS and SAT3, due to cost reasons.
The impact will not be as severe as in January, though. All international traffic is being redirected via alternative cable routes. This may be a viable method for connecting users to the Internet but might not be suitable for latency-sensitive applications like International video conferencing.
SA cellphones to be tracked to fight coronavirus
Several countries are tracking cellphones to understand who may have been exposed to coronavirus-infected people. South Africa is about to follow suit, writes BRYAN TURNER
From Israel to South Korea, governments and cell networks have been implementing measures to trace the cellphones of coronavirus-infected citizens, and who they’ve been around. The mechanisms countries have used have varied.
In Iran, citizens were encouraged to download an app that claimed to diagnose COVID-19 with a series of yes or no questions. The app also tracked real-time location with a very high level of accuracy, provided by the GPS sensor.
In Germany, all cellphones on Deutsche Telekom are being tracked through cell tower connections, providing a much coarser location, but a less invasive method of tracking. The data is being handled by the Robert Koch Institute, the German version of the US Centers for Disease Control and Prevention.
In Taiwan, those quarantined at home are tracked via an “electronic fence”, which determines if users leave their homes.
In South Africa, preparations have started to track cellphones based on cell tower connections. The choice of this method is understandable, as many South Africans may either feel an app is too intrusive to have installed, or may not have the data to install the app. This method also allows more cellphones, including basic feature phones, to be tracked.
This means that users can be tracked on a fairly anonymised basis, because these locations can be accurate to about 2 square kilometers. Clearly, this method of tracking is not meant to monitor individual movements, but rather gain a sense of who’s been around which general area.
This data could be used to find lockdown violators, if one considers that a phone connecting in Hillbrow for the first 11 days of lockdown, and then connecting in Morningside for the next 5, likely indicates a person has moved for an extended period of time.
Communications minister Stella Ndabeni-Abrahams said that South African network providers have agreed to provide government with location data to help fight COVID-19.
Details on how the data will be used, and what it will used to determine, are still unclear.
