Way-C tablet and Elikia smartphone - Africa’s answer to the iPad and iPhone
Source: http://www.howwemadeitinafrica.com/interview-the-man-behind-africa%E2%80%99s-answer-to-the-ipad-and-iphone/20202/
Vérone Mankou is the 26 year old entrepreneur behind the African designed Way-C tablet computer. The tablet was launched earlier this year and attracted significant media attention. Mankou’s company VMK, which is based in the Republic of the Congo, this month also unveiled its first smartphone. "How we made it in Africa" asked Mankou about the business and how his company competes with the likes of Apple and Samsung.
Why did VMK decide to launch the Way-C tablet?
The project began in 2006. I was working at an internet service provider (ISP) and wanted to design a cheap computer to give access to internet for more people. After one year, when Steve jobs unveiled the first iPhone, I changed my plan and the project became the “big iPhone”, meaning a tablet.
Earlier this month VMK also introduced its first smartphone, just days before the launch of the iPhone 5. Why enter the smartphone market?
You know, when I was working on the tablet, I noticed that the biggest difference between a tablet and a smartphone is the screen size. After we launched the tablet we decided to work on a smartphone project, and now the project is finished. It’s a Android phone called the Elikia (which means “hope”).
Your products are designed in Africa, but assembled in China. Tell us a bit more about the design and manufacturing process.
You know it’s like building a house. Firstly you have an architect who draws the house and after you have the workers who will build that house using the plans of the architect, but the architect need to be there every time to check if everything is okay. And for the designing of a tech product, it’s the same.
You mentioned in a previous interview that you will roll out 3G enabled tablets.
The first version of the tablet was Wi-Fi only, and many people didn’t like this. They asked us to develop a 3G tablet, so now we are working on a 3G tablet that we will launch in the beginning of next year.
How do you compete with multinational tablet manufacturers such as Apple and Samsung?
For me Apple and Samsung are not interesting in Africa, because their cost is so high. My goal is to put a tablet in the hands of all Africans, their goal is just to make money. It’s different.
VMK has also launched a market place for African-focused apps. Tell us more about this.
I noticed that in Android Market, now called Play Store, more than 99% of apps are not developed in Africa and/or are not developed for Africa. When you search African content, it’s hard to find good ones. We decided to launch our own marketplace to help us promote African content. And for the smartphone Elikia we decided to launch a new version of our market, called VMK Market, with the possibility to buy apps via our gift card, called VMK Market Card. So now we are developing a real environment (including devices, content and monetisation) to help developers.
Describe some of the greatest challenges you are facing in making the Way-C a success.
Our biggest challenge is just to get funding, because it’s needed to produce more products and for marketing purposes.
What is needed for Africa to become a serious player in the tech industry?
Funding and innovation.
What does the future hold for VMK?
We decided to launch a tablet and smartphone. It’s done. Now I want to give all African households access to technology, and develop a new tablet for education priced at about US$100.

Antimatter Positrons in Banana, Yam, and Plantain
· Potassium-40 is a
naturally occurring isotope that is unstable and radioactively decays.
· The radioactive
half-life of Potassium-40 is 3.938×1016 seconds.
· The atomic mass of
Potassium is 39.1 g/mol.
· When Potassium-40
radioactively decays, 1 in every 100,000 decays emits an Anti-Electron or Positron
particle of Antimatter.
· For every 1,000,000
atoms of Natural Potassium, about 117 atoms are Potassium-40.
· Therefore, substances
dense with Potassium will likely contain Potassium-40 and will also
occasionally emit Antimatter in the form of an Anti-Electron.
Bananas are food that is rich with
Potassium. Let’s calculate the
Anti-matter emitted by an Average Banana.
·
1 Average Banana
contains 0.450 grams of Natural Potassium
=
0.450 g × (6.02×1023) atoms/mol ÷ 39.1 g/mol = 6.93×1021
atoms of Potassium
Remember that for every 1,000,000 atoms of Natural
Potassium, about 117 atoms are Potassium-40.
So to find the number of atoms of Potassium-40 in our Potassium atoms
we
=
(117 ÷ 1,000,000) × 6.93×1021 atoms
= 8.11×1017 atoms of Potassium-40
To find out how many decays of Potassium-40 occur
per second, we divide our total number of Potassium-40 atoms by the radioactive
half-life of Potassium-40 which is 3.938×1016 seconds
=
8.11×1017 atoms of Potassium-40 ÷ 3.938×1016 seconds = 20.58 decays of Potassium-40 per second
·
Now
remembering that 1 in every 100,000 decays of Potassium-40 emits a Positron
particle of Antimatter, then we can calculate how often a Positron particle of
Antimatter is emitted from our banana by
= (100,000 decays ÷
20.58 decays per sec.) ÷ 60 sec. per min.
=
Every 81 minutes an Anti-Electron
Antimatter particle is emitted from a Banana
Yam and Plantain are two foods common
in African and Caribbean diets which are higher in Potassium content than
Banana. Let’s use the formulas provided
to calculate how long it will take for the African Yam and Plantain to emit a Positron
particle of Antimatter.
·
1 Average Plantain
contains 0.534 grams of Natural Potassium
= 0.534 g × (6.02×1023) ÷ 39.1
= 8.22×1021
atoms of Potassium
=
(117 ÷ 1,000,000) × 8.22×1021 = 9.62×1017 atoms of
Potassium-40
= 9.62×1017
÷ 3.938×1016 = 24.43 decays of
Potassium-40 per second
= (100,000 decays ÷ 24.43 decays per sec.) ÷ 60 sec. per min.
=
Every 68 minutes an Anti-Electron
Antimatter particle is emitted from a Plantain
·
1 Average African Yam
contains 0.694 grams of Natural Potassium
= 0.694 g ×
(6.02×1023) ÷ 39.1 = 10.7×1021 atoms of Potassium
=
(117 ÷ 1,000,000) × 10.7×1021 = 12.5×1017 atoms of
Potassium-40
= 12.5×1017
÷ 3.938×1016 = 31.75 decays of
Potassium-40 per second
= (100,000 decays ÷ 31.75 decays per sec.) ÷ 60 sec. per min.
=
Every 53 minutes an Anti-Electron
Antimatter particle is emitted from an African Yam
Jamaican
sprinter Yohan Blake eats 16 Bananas per day. There
are 1440 minutes in a day; therefore, Yohan Blake takes in about 18 Positron
Antimatter particles per day just from eating Bananas. Perhaps
the consumption of the Anti-matter found in Yam, Plantain, and Banana is what
has led to the superior performance of Yohan Blake, Usain Bolt, and the other
Jamaican sprinters in this year’s Olympic Games.
For
this and other African science experiments, be sure to check out the book “9Ether RE Engineering”, and for recipes on how to prepare African Yam and
Plantain, be sure to check out the book “Back To Our Roots, Food for the Gods”
