Our Mining Heritage

Our Mining Heritage

The beautiful month of September not only marks the beginning of Spring, it is also the month devoted to Heritage.

A country’s natural heritage is its natural resources and beautiful environment, because they are considered to be so unique that they are internationally respected and protected.

South African heritage, might be anything from famous stretches of coastline in Kwazulu-Natal, to shweshwe fabric, to Bunny Chow or Potjie. But for now lets take a look at our mining heritage and history.

Mining in South Africa was once the main driving force behind the history and development of Africa’s most advanced and richest economy.

Did you know:

South Africa is the world’s largest producer of Chrome, Manganese, Platinum, Vanadium and Vermiculite.

Platinum and Palladium:
South Africa produces more platinum and similar metals than any other country.
In 2005, 78% of the world’s platinum was produced in South Africa, along with 39% of the world’s Palladium.
Over 163,000 kilograms of platinum was produced in 2010, generating export revenues of $3.82 billion USD
Currently Russia and South Africa are the biggest palladium producers in the world.

  • South Africa is the second largest producer of Ilmenite, Palladium, Rutile and Zirconium.
  • South Africa is also a huge producer of Iron ore: In 201 2 it overtook India to become the world’s third-biggest iron ore supplier to China.
  • South Africa has the second-largest reserves of uranium in the world.
    (NUFCOR) (The Nuclear Fuels Corporation of South Africa) started processing Uranium as a by-product of gold mining in 1967.
    Most of the uranium produced is concentrated in the golf fields of the Witwatersrand area.


  • South Africa’s production of chromium accounted for 100% of the world’s total production in 2005, and consisted of 7,490,000 metric tons of material.

Chromium is used in stainless steel and for a variety of industrial applications.

  • South Africa is the world’s third largest coal exporter.
    Much of the country’s coal is used for power production as 77% of South Africa’s energy needs are provided by coal.

Gold was discovered in the area known as Witwatersrand, triggering what would become the Witwatersrand Gold Rush of 1886.
South Africa accounted a percentage of 15% of the world’s gold production in 2002 and 12% in 2005, though South Africa has produced as much as 30% of world output as recently as 1993.
Despite declining production, South Africa’s gold exports were valued at $3.8 billion USD.

  • It was estimated by US Geological Survey in that as of 2002, South Africa held about 50% of the world’s gold resources, and 38% of reserves.


“Diamonds are a girls best friend”

Did you know:
Diamonds are valued by weight, colour, clarity and various other factors.
The first diamond was discovered on the banks of the Orange River in 1867 by Erasmus Jacobs.

  • Of “The 10 Largest Diamonds Ever Discovered” – Four are from South Africa!

The Jonker: 726 carats
This giant stone, was found by a settler called Johannes Jacobus Jonker in 1934.
It’s believed the rough diamond was cut into 13 smaller stones, with the largest diamond, the Jonker I, still weighing in at an incredible 142.9 carats.

The Golden Jubilee: 755 carats
The golden Jubilee was discovered in 1985, it was eventually cut and faceted diamond that weighed an enormous 545.67 carats, making it the largest finished diamond in the world.
It is currently owned by the Royal Family of Thailand.

Excelsior Diamond: 995.20 carats
Was Found in 1893 in Jagersfontein Mine, this huge rock was cut into many smaller pieces. The largest gemstone cut from this famous diamond was 69.68 carats.

Cullinan Diamond: 3106.75 carats
The Cullinan, was discovered by a mining superintendent in old Transvaal in 1905.
Also known as the Star of Africa, this is arguably the most famous diamond in the world.
Weighing more than three times the weight of the Excelsior Diamond, it was named after the owner of the mine, Sir Thomas Cullinan.
It was given as a gift to the King of the United Kingdom (Edward VII). Nine large stones and 96 stones were taken from the rough diamond, including the famous Star of Africa (Cullinan I) which is 530.2 carats and is now part of the Crown Jewels, inserted into the Sceptre with the Cross.
The value of the Cullinan diamond has been estimated at $2 billion.


We live in one of the most beautiful and most resourceful countries in the world.

As former President Nelson Mandela stated:
“When our first democratically-elected government decided to make Heritage Day one of our national days, we did so because we knew that our rich and varied cultural heritage has a profound power to help build our new nation.”


Lets choose to acknowledge, respect, and celebrate our culture and the diversity of beliefs and traditions to rather use this power to promote peace and to build a stronger nation.

Some WACKY & BIZARRE sources for Alternative ENERGY!!

Some WACKY & BIZARRE sources for Alternative ENERGY!!

Did you know?

When I think of Green or Alternative Energy, I think of Wind and Solar Energy! But wind energy is inconsistent, and solar energy can’t be harnessed at night or on cloudy days.
Unfortunately, we live on a planet of finite resources, and we have some really clever scientist who rather than wait for the oil wells to run dry and coastal cities to disappear beneath rising sea levels, are exploring more unusual sources of producing and harnessing renewable energy, and decreasing worldwide dependency on fossil fuels.
With fossil fuels on the verge of being exhausted, the search for abundant, cheap energy is constant, and has led to some pretty strange, surprising and even ridiculous discoveries, some “pleasant” like coffee or chocolate and some “not so pleasant” like poop!

Here are 14 of the wackier ideas for alternative energy in no particular order!


Everywhere you look these days, people have their heads down, vigorously texting away as though their lives depended on it. Americans sent a whopping 12.5 billion text messages in just one month in 2006, and cell phone users in the United Kingdom send out one billion a week. Although it can be annoying, what if each of those finger taps could generate power?
That is the idea behind Push to Charge, one of the innovative entries into the 2008 Greener Gadgets Design Competition. The concept relies on what’s called piezoelectricity. Some metals can build up an electric charge under pressure, and this effect can be used to generate energy on surfaces like roads, floors and even cell phone screens.
The Push-to-Charge cell phone would feature plastic buttons sitting atop a layer of hard metal. The bottom layer would be made out of piezoelectric crystals, so that each time you pressed a button, the hard metal directly underneath it would hit the underlying crystal like a hammer, creating a small amount of voltage. Small wires located between the layers would convey the charge to a battery for storage.
The same technology could be used in any other product that features buttons, including computer keyboards and video games.
You have to agree that generating electricity simply by typing on a keyboard or keeping in touch with your friends and family is pretty awesome.

Wacky no 2. SUGAR

Did you know?: That sugar can be converted to hydrogen and that it could be a way to fuel a vehicle.
Researchers at Virginia Tech University are developing a way to convert sugar into hydrogen, which can be used in a fuel cell, providing a cheaper, cleaner, pollutant-free and odourless drive.
The method involves combining plant sugars, water and 13 powerful enzymes in a reactor, converting the concoction into hydrogen and trace amounts of carbon dioxide. The hydrogen could be captured and pumped through a fuel cell to produce energy. This process delivers three times more hydrogen than traditional methods, which translates into huge cost savings.
Research is also underway to develop the same technology to create long-lasting sugar-based batteries for laptops, cell phones and other electronics, although it could be another ten years before we begin to see any results from these experiments or before consumers can actually dump sugar into their fuel tanks.


Did you know?: That the food and waste we throw out on a daily basis can be used to generate biofuel which can, in turn, be used as an alternative source of energy.
Our leftover foods such as fruit skins or coffee as well as other organic matter when stored and degraded over a period of time, generate methane and several other gases that can be used as biofuel.
Many small-scale industries have, in fact, started generating electricity with the biogas generated from collecting garbage.

Wacky no 4. BACTERIA (E.COLI)

If you are like ME, the word ‘E. coli’ makes me want to run for the hills!
But did you know?: That this tiny organism commonly associated with stomach cramps and vomiting could actually alleviate some of our energy challenges … by excreting crude oil.
As you know the world is full of bacteria which, like every living organism, have a survival plan for when food is in short supply. E. coli bacteria store fuel in the form of fatty acids, the same fatty acid that is needed for the production of biodiesel fuel.
Scientists removed enzymes from the bacteria to boost fatty acid production and then dehydrated the fatty acid to get rid of the oxygen, which turned it into a type of diesel fuel. That means because of the raw materials it uses, the process will take even more carbon out of the atmosphere than what it puts back in. And these organisms wouldn’t rely on any single agricultural waste, thereby eliminating the controversy over using specific food crops for fuel. Instead, the process would rely on whatever is abundant in the local environment.
The same bacteria that can make us sick can also help save people money and our environment, by providing fuel for transportation.

Wacky no 5. BODY HEAT



Finally, we’re reverting back to the traditional way of harnessing energy – Natural Body Heat!
Did you know?: The heat your body produces can warm an entire building? At least that’s what is happening in Stockholm and Paris, but Sweden has the most efficient method of harnessing it.
The body heat generated by the 250,000 commuters who crowd Stockholm’s railway station (Scandinavia’s busiest travel hub) each day is immense. This heat used to drift off into the air and was wasted until engineers have figured out a way to harness it and transfer it to a newly renovated office building down the block.
The heat generated by the commuters is captured by the station’s ventilation system and used to warm water in underground tanks. This water is then redirected into the office’s ventilation, thus heating the entire block.

Wacky no 6. HUMAN WASTE (NOT so Pleasant)

Did You Know?: That faeces (poo) contain methane, a colourless, odourless gas that could be used in the same way as natural gas, instead of fossil fuels.
At Delft University of Technology in the Netherlands, researchers are working on an alternative to fossil fuels. They’ve developed a state-of-the-art toilet for use in developing countries that employs microwaves to chemically alter human waste into syngas, a mixture of carbon monoxide and hydrogen. This syngas can then be used in stacks of fuel cells to generate electricity, where one toilet could generate enough energy to power several households.
In Bristol, Australia a VW Beetle car is powered by methane captured from a raw sewage treatment plant. Engineers from Wessex Water estimate the waste from 70 homes can generate enough gas to make the car run for 10,000 miles.
Some companies claim to have found the best source: used nappies, as it’s an unlimited resource. Urea, on the other hand, due to its saline properties, can be easily hydrolysed to obtain hydrogen. Overall, urea is better than simple water for this process.
Urea is also an accessible, non-toxic, organic chemical compound rich in nitrogen. So, humans are constantly carrying around a chemical compound that can produce electricity.

Wacky no 7. Cows

Did you know?: That Cows are responsible for 18 percent of greenhouse gas emissions.
A 2006 United Nations report estimated that cows, along with other livestock like sheep and goats, contribute about 18 percent of the greenhouse gases that are warming the planet. More than cars, planes and all other forms of transportation put together.
That’s largely true because bovine emissions are rich in methane, a gas that’s 21 times more efficient than carbon dioxide at trapping heat in the atmosphere.
Scientists have already developed a method for extracting methane from cow excrement and converting it to a biogas fuel that’s of sufficient quality to be fed into a standard natural gas pipeline. In California, a company called BioEnergy Solutions uses that method to produce 18,406 cubic meters of biogas from manure, enough to power 200,000 households.
Six hundred cows that produce 18,000 gallons of manure daily are helping a farm in Pennsylvania save $60,000 a year. The waste is used to produce electricity, bedding, fertilizer and heating fuel.
And Hewlett-Packard recently released a study explaining how a dairy farmer could make money by leasing land to Internet server companies, who could power computers with the methane.
In Argentina, a major beef producing nation where the collective herd of 55 million cattle outnumbers the human population, researchers have developed a special bovine backpack that captures a cow’s emissions via a tube attached to the cow’s stomach and discovered that the animals produce between 800 and 1,000 litters of gas each day.

Wacky no 8. VIBRATIONS

Did you know?: That the kinetic energy of people walking, dancing or jumping can be converted into electricity.
Need an excuse to go out clubbing? Club Watt in Rotterdam, Netherlands is using floor vibrations from people walking and dancing to power its own light show. A number of dance clubs in Japan have already implemented this technology in order to make their establishments self-sustainable.
This concept works on the principle of piezoelectricity. Piezoelectricity is produced when stress or strain is applied to an object, which can then be converted to electricity (see wacky no 1).
The technology used in the sustainable dance floors could potentially be applied to other situations, such as a bus or train station, for example, to make the most of kinetic energy generated by movement.
The U.S. Army is also looking at piezoelectric technology for energy. They put the material in soldier’s boots in order to charge radios and other portable devices, doable but not cheap.

Wacky no 9. Jellyfish

Did you know?: Jellyfish that glow in the dark contain the raw ingredients for a new kind of fuel cell.
Their glow is produced by green fluorescent protein, referred to as GFP. A team at the University of Technology in Gothenburg, Sweden placed a drop of GFP onto Aluminum electrodes and then exposed that to ultraviolet light. The protein released electrons, which travel a circuit to produce electricity.
The same proteins have been used to make a biological fuel cell, which makes electricity without an external light source. These fuel cells can be used on small, nanodevices such as those that could be implanted in a person to diagnose or treat disease.

Wacky no 10. Carbon Nanotubes

Carbon nanotubes are a form of carbon, similar to graphite found in pencils. They are hollow cylindrical tubes and are 10,000 times smaller than a human hair, but stronger than steel. They are also good conductors of electricity and heat and have a very large surface area.
Carbon nanotubes have a range of potential uses, from armor-like fabrics to elevators that could lift cargo between Earth and the Moon. Recently, scientists from MIT have found a way to use carbon nanotubes to collect 100 times more solar energy than a regular photovoltaic cell.
The nanotubes could work as an antenna to capture and funnel sunlight onto solar arrays. This means that instead of having an entire rooftop covered in solar panels, a person may need just a small space.

Wacky no 11. Coffee Waste (Pleasant)

If you are like me, coffee is a life necessity that you absolutely can NOT go without!
But did you know?: That the cup of coffee that helps fuel you for the day, could soon also be used to produce bio-diesel fuel?
Every year, the global population consumes 600 billion cups of coffee. An average coffee shop throws out 10 kg of coffee every day. However, the coffee grounds that are thrown away can actually be used to produce bio-diesel fuel.
If all coffee grounds could be converted this way, it would create 2.9 million gallons of biodiesel every year. If all of the leftover grounds from Starbucks were reprocessed, they would produce 89,000 tons of such fuel pellets annually, enough to generate millions of dollars in revenue for the coffee-shop chain, as well as help counter rising fuel costs.
There will eventually be a time when your grandchildren will be filling up their car’s fuel tank with some coffee!

Wacky no 12. ALGAE

Did you know?: That Algae has a higher heat content than corn or sugar, making it more efficient as a fuel source?
Algae, yes the slimy green stuff you find at the bottom of a dam, contains cells which produce oil. In fact, half of its body weight is lipid oil. Lipid oil can be harvested and converted into fuel. The resulting biodiesel is more clean and efficient than petroleum and is more sustainable.
Although there are a few obstacles stopping algae fuel from being utilized on a huge scale, much research is being done to overcome these issues. The space that’s required to grow enough algae to produce a significant amount of oil, for example, is one obstacle. As is the fact that conditions, such as temperature, must be exact to enable optimum growth, which may be difficult to control.
The most promising option on this list, however, is algae, which could realistically replace fossil fuels on our planet.

Wacky no 13. ELECTRIC EELS

Did you know?: An Electric Eel can discharge an electrical current of over 400V at once?
Researchers are attempting to find a way to use this electric power of Electric Eels. This mechanism is used by the fish to defend itself from predators and to hunt small fish, but its main purpose is that of a radar system, a replacement for its nearly blind eyes.
A successful experiment was even conducted in Japan where a Christmas tree was lit up using the electricity generated by an eel.

Wacky no 14. Chocolate (Pleasant)

Did you know?: The shells of cocoa beans can also be converted into biofuel?
The waste left over namely cocoa bean shells from a chocolate factory in the U.K. was fed to E. coli bacteria, which resulted in the production of hydrogen. Hydrogen is one of the cleanest fuels, it’s only by-product being water.
The fat from chocolate was also converted into biofuel and used to power a racing car, which reached 130 miles per hour on a racetrack.

Wow!, Who would have thought that we could be saving our planet by drinking more coffee or indulging in chocolate, or by dancing the night away!!

What is your favourite wacky and bizarre alternative?

L2B Blog: Fresh ideas about airconditioning

posted in: General 8

If you live in Durban like I do, you would know that living without air-conditioning or some sort of cooling system is absolute TORTURE!

In the extreme heat of summer, it can be quite tough to look and smell clean & fresh (TRA-LA-LA) all the time! There have been days where it felt like my makeup was literately melting off my face, not to mention the regular ‘sniff’ checks I needed to perform, not wanting to scare any potential subscribers away by looking like ‘The Crow!’

First, let’s go back in time:
One of the first A/C systems was invented by Willis Carrier in 1902 and was called the Ice Machine. It was developed to bring down the temperature and remove the humidity from the air.



Current time:
It’s been predicted by the Netherlands Environmental Agency, that by 2060 the amount of energy used worldwide in COOLING will overtake the energy used for HEATING.
As it stands, the United States uses as much energy to keep things COOL as the whole of the African Continent uses on EVERYTHING. Countries like India and China are fast catching up and by mid-century we will use more energy for cooling than heating!



But it’s not all “DOOM and GLOOM”

Since then, technology in A/C has improved and evolved dramatically. In 1992 conservation standards for manufacturers of central air conditioners and the heat pump were issued and in 2006 the energy SAVING from 2006 to 2035 is equivalent to the annual greenhouse gas emissions of about 72 million cars.
It has improved so much that the A/C today uses about 50% less energy that they did in 1990.


One of the ways to save not only on your electricity bill but also our planet, is a solution called: Ducted Reverse Cycle Air-Conditioning. It’s an Energy Efficient Solution for your home.
And because I had no clue what ” Ducted Reverse Cycle Air Conditioning” was before I did my research for this Blog, I think its a good idea to explain with a picture. 🙂



Ducted Reverse Cycle Air-Conditioning works through a fan that draws the hot air from your house and transfers it over a cold liquid called refrigerant. The air is then cooled and flows back throughout your house. The hot air that flows from the compressor evaporates. The compressor creates high-pressure gas and high-temperature gas. This gas is then pumped through to a heat exchanger that is located outside. Because the heat is able to escape, the refrigerant can then cool.

Benefits of this system:
* You have the option to either heat or cool a room
* It allows you to control the temperature from a control panel
* Sensors in different rooms ensure the correct temperature is maintained
* Comes with a zoning function option, allowing you a selection of different air flow and temperatures for different rooms


Very impressive: The Fourleaf Estate residential development in Port Elizabeth is the VERY FIRST residential project in AFRICA to meet the Edge resource-efficiency standard and to receive an “Edge final certification” from Green Building Council South Africa (GBCSA).
Click here to view details of this Project on L2B


If you are going to “FLIP that SWITCH”, herewith are some pointers on SAVING ENERGY:

Generally, the best temperature to set your A/C unit is around 24-25°C.
You can save considerably on the amount of energy used for each 1°c of heating or cooling that you do without. Should it be 35°C outside, by setting the temperature around 25, instead of 22, you could save a significant amount of energy.


And for those of us that DON’T have the LUXURY of air-conditioning, herewith some suggestions to keep cool:

* Shade your windows in summer with curtains, shutters and blinds that can reduce heat absorption by up to 80%.

* Create more shade outside of your house with awnings and trees.

* Hack a fan.

* Set your ceiling fans to rotate counter-clockwise. Some ceiling fans even come with a remote control.

* Let the night air in by keeping windows open.

* Focus on your body temperature by hydrating with cold drinks.

* Install UV film on your windows to reduce heat and glare.

* And lastly, instead of cooking indoors, in true South African style, “NOU GAAN ONS BRAAI!


So, regardless if you want to CRANK UP the temperature during the cold winter months or DOWN in summer, consider that WE ONLY HAVE:
