Sweden Pledges To Invest in Zim ICT Sector

Yesterday, the Swedish ambassador to Zimbabwe Mr Lars Ronnas met the minister of ICT, Postal and Courier Services, Cde Supa Mandiwanzira, at the ministry’s offices where he pledged that the Swedish government is committed to work with Zimbabwe in opening new avenues of cooperation especially in the telecommunications sector.

Sweden is considering investing in the information communication technology sector in Zimbabwe.

This came out after the Swedish ambassador to Zimbabwe Mr Lars Ronnas paid a courtesy call on the Minister of ICT, Postal and Courier Services Cde Supa Mandiwanzira.

Mr Ronnas says his country is committed to work with Zimbabwe in opening new avenues of cooperation.
The Swedish envoy says his country is interested in the development of the telecommunications sector.

“Sweden is a leading country in ICT and we are interested in investing in the sector. Our countries have long standing relations and we will continue to explore more areas of possible cooperation,” said Mr Ronnas.

Sweden is ranked high in terms of information communication technology and Zimbabwe feels the Nordic country can be the ideal partner.

ICT, Postal and Courier Services Minister Cde Supa Mandiwanzira revealed that the government has already reserved 74 hectares of land for companies that deal in ICT at the Special Economic Zone in Ruwa.

“There are a number of opportunities we need to explore and we want to rope in Sweden in the development of the ICT sector. There is as lot to learn from Sweden in terms of developing the sector,” Cde Mandiwanzira said.

A high powered ICT business delegation from Sweden is expected to visit the country in September to explore available business opportunities.

This comes as the government has directed mobile operators to work together and share infrastructure to reduce capital expenditure.

What Is Crowdfunding??

Today we explore on a word that has managed to get most startups going around energised as we face potential help to fund ideas, into real projects via the emergence of many startup hubs in Zimbabwe.

Though this option is not yet prevalent in Zimbabwe, all we have are so far are what we call potential Venture capitalists, a topic we will look into separately.

Do you have an idea but cant access funds from a bank and you are possibly afraid of money lenders… well this avenue might be for you.

Crowd funding is technically defined by forbes as “the practice of funding a project or venture by raising many small amounts of money from a large number of people, typically via the Internet.”

There are two basic concepts
– All or Nothing (AoN) – When the fund-raising period is over, money is only collected from the contributors if a pre-determined minimum amount of money has been pledged. If the goal is not met, no money is collected.

– Keep it All (KiA) – Whether the project goal is met or not, all of the funds collected (minus commission) are handed over to the entrepreneur. If he or she has insufficient funds to meet the objectives, then it is up to the recipient to refund them to the contributors.

So this has been around for ages people, it only now got revolutionary and some new phenomenon because he internet is becoming a “house hold name tool’ for a lack of a better term. You as a tech-prenure gets a banging idea which follows the following steps

1. Follow your dream.
2. solve a consumer or business need
3. Take the risk- leave your comfort zone and be bold
4. Make the sacrifice. This is where your potentially crowd funded idea comes in
5. Be persistent- if one person says no to you move on the next, then go back to them until they want
6. Know your customer- if your customer wants blue but you have red… give them blue or sell them red…
7. Sell to survive and prosper- work hard and make sure the start-up ( be it a business or an app or whatever it is sells)
8. Hire the right employees/ work with the correct people- the correct people around you help with good ideas
9. Call upon mentors- you’re not a one man army so ask for help
10. Communicate constantly

The point f crowd funding is as the name says, fund from crowds. The investor could possibly be you customer also so you idea must make sense to them and also be able to make money for them.

What is Turbo Charged Engine and How Does It Operate?

Its again another Thursday where we dissect facts on science and technology related issues. Today, we want to talk about the turbo charged engines.

You’ve heard the word “turbo” tossed around a lot, especially by performance car enthusiasts. I am sure many of us have witnessed the behavior exuded by “Hwindis” (commuter omnibus conductors) at their loading bays.

By Tongai Mwenje

You could hear them cheering up their buses, shouting and whistling , “Vape moyo” (give them the heart) referring to the engines of their buses. The driver of the bus would respond by thundering the engine….vooooooom!!!!

The engine would go for minutes under those rants, only to prove the efficiency and power of their turbo charged engines. This is routinely done to attract passengers, popularly referred to as “shura” by the hwindis.

But all you know about turbo charged engine is that it means an engine has more “oomph” to it than normal. But what exactly is going on underneath that hood?

Let’s open it up and take a look.

A turbocharger, or turbo, is a turbine-driven forced induction device that increases an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber.

Before you can truly appreciate what a turbocharger does for an engine, you need to understand the basics of internal combustion.

Internal combustion engines are “breathing” engines. That is to say, they draw in air and fuel for energy. This energy is realized as power when the air-fuel mixture is ignited. Afterward, the waste created by the combustion is expelled. All of this is typically accomplished in four strokes of the pistons.

What a turbocharger does is to make the air-fuel mixture more combustible by fitting more air into the engine’s chambers which, in turn, creates more power and torque when the piston is forced downward by the resulting explosion.

It accomplishes this task by condensing, or compressing, the air molecules so that the air the engine draws in is denser. Now, how it does that is the real story here.

A Tale Of Two Wheels

A turbocharger is basically an air pump. Hot exhaust gases leaving the engine after combustion are routed directly to the turbine wheel side of the turbocharger to make it rotate. That turbine wheel is connected by a shaft to a compressor wheel.

As the turbine wheel spins faster and faster, it causes the compressor wheel to also spin quickly. The rotation of the compressor wheel pulls in ambient air and compresses it before pumping it into the engine’s chambers.

As you may have guessed, the compressed air leaving the compressor wheel housing is very hot as a result of both compression and friction. So what’s needed is a way to cool that air down before it enters the chambers. That’s where a charge-air cooler (or “heat exchanger”) comes in.

It reduces the temperature of the compressed air so that it is denser when it enters the chamber (heat causes things to expand, as we all learned in science class). The charge-air cooler also helps to keep the temperature down in the combustion chamber. All together, the engine, turbocharger and charge-air cooler form what is known as a “charge-air system”.

Some systems also include a tip turbine fan which draws air across the charge-air cooler to further reduce the temperature of the compressed air generated by the turbocharger.

Not As Easy As It Looks

The basic principal behind turbocharging is fairly simple, but a turbocharger is a very complex piece of machinery. Not only must the components within the turbocharger itself be precisely coordinated, but the turbocharger and the engine it services must also be exactly matched.

If they’re not, engine inefficiency and even damage can be the results. That’s why it’s important to follow correct installation, operating and preventative maintenance procedures.
