Editors Letter March - Autumn - nippy in the morning. All of those things. Nearly tme to find the blankets and the heater.

But to warm us all up, we have found some interesting things for you: Easter is nearly here, but why is it always on different dates? why not just fix it in time - once and for all? Not so simple. Read on. And of course science. This time it is Nanotech. Where are we? will it ever deliver.

Our own Masiziba is sharing more with us on what university life is all about. First year is both challenging and hard, but mostly fun.

China is the International focus. Building islands and flexing its muscles.

Why really? - we give our view on that. ... and of course something from my poetry book.

Sybil

Time for poems: Autumn, the time when the grass goes brown The rain stops, the cold snap The cold in the morning The time for indoor Granny’s soup, the socks Time for so much And there is still no time Not enough And time is now Time is going and time is coming we can never get it to just stand still

Sybil

We need writers!

Our writers are growing up and getting older That is og course good. BUT.... it means they are leaving us Therefore: would you like towrite for us?

What is required?

That is easy You have to be in grade 10-12 Impeccable in your preferred language-and that might not be English. We try to be more than just English Passionate about your topic of choice no dull articles here

Look what Rofhiwa said: My name is Rofhiwa and I love to write.

I think I am rather decent writer too.

I took my talent and have used it to express my thoughts on international dealings of the world which have been published in Hola MaHigh-School. It has paid off, not only is my work printed for young people in the country to read, but it also contributed to me gettng a bursary from CNBC-Africa to do my post-graduate studies. Would be a lot harder to get by if I didn’t have platform like Hola MaHigh-School.

Stagedoor -

Stage door is a first-year showcase event where talented first years are chosen to participate in drama and singing. It aims to make a statement about issues on campus through Art. However, there is a debate around whether one should encourage first years to participate in such events mainly since they are finding their feet. Some first year parents do get overwhelmed and feel it is absolutely the wrong time for events like these.

For some, being part of Stage Door has been extremely fun while others have felt the need to pull out because of seeking “a balance” and finding their way around.

Stagedoor 2017 took place on 4 march 2017 at Kovsie Church. This event consisted of eight junior residences that went through to the finals. These residences performed their drama and singing on a wide variety of venues the day before finals around campus—rotations so as to gain access to the finals. Their themed drama and singing tackled some of the widely controversial issues of our society under catch phrase “let’s make stage door great again”.

Some of the issues tackled were the registration frustration, the current state of the Springboks, and communication and/or customer care while others were putting emphasis on how life and 2017 should be made great again, and of course, the game of South African politics.

Within the depth of their catch phrases came along other controversies such as the management of the University, Shimla report and how there were strikes in September 2016 plus the “one”

2017 - at UFS returning NSFAS student.

The first years and spectators also had fun. The prescribed joke was “catch me outside” and they pulled it off from all angles. Some residences also threw some shade onto other residences which sparked a lot of energy in the crowd.

The singing and dancing was exceptional too. The main theme song was ‘we don’t talk anymore’. It was a unifying song that every group had to sing. It somehow summed up the message that they were sending. They suggested that all these topics could be tackled through intensive dialogues and not just through the cracked screens of phones and Social Media.

Kgomotso, a first year from Beyers Naudé, won the dance-off.

Other winners included Bacon (Beyers Naudé and ConLaurês) who won best singing for the theme song and best catch phrase and came overall second place. The best actress was from Marjolein while the best actor was from Armentum who portrayed the character of Moafrika.

However, the overall winners were Sonnedou and Roosmaryn who walked away with a cash price of R7,000 each and Red Bull drinks and bragging rights for the whole year.

Easter Rand Show All from The show was first held at the Old Wanderers cricket ground in November 1894 by the Witwatersrand Agricultural Society, a society that had formed in March of the same year.

The second show was opened by Paul Kruger on 13 March 1895, at a venue called Milner Park, which is today the site of the University of the Witwatersrand’s West Campus.

It was held again in 1896 and reestablished subsequent to the end of the Anglo Boer War, in 1907. In 1936, the Rand Show was called the Empire Exhibition.

The eleven-day show was historically an agricultural exhibition for all South Africans where livestock, poultry, yearlings, farm products and equipment were shown and judged with prizes awarded in the form of Gold and Silver medals.

In later years it also featured industrial and commercial exhibitions and would eventually attract foreign participants who would exhibit country pa-

w - a brief history m Wiki vilions. Other annual exhibitors included Military Tattoos, the South African Defence Force,the South African Police as well as show-jumping competitions.

The 1960 show was the site of a failed assassination attempt on Prime Minister Hendrik Verwoerd, by white farmer David Pratt.

Venue after 1984.

It continued to be held at Milner Park until 1984, when it was moved to the Expo Centre at Nasrec, and the brand was sold in 2000 to company Kagiso Exhibitions & Events, a subsidiary of Kagiso Media.

In 2009, the Rand Show was to have moved to Gallagher Estate, with a separate Joburg Easter Festival being held at the Nasrec Expo Centre, however, the Expo Centre

bought the Rand Show brand back from Kagiso, and the Rand Show was held, as normal, at Nasrec, as the Joburg Easter Festival, incorporating the Rand Show.

Easter! - why not So, we thought it could be done?

This is something wars have been fought over, people killed, conspiracies and ancient rituals. This is better than ... Kardashians!

Here is what Wiki is saying: Easter and the holidays that are related to it are moveable feasts, in that they do not fall on a fixed date in the Gregorian or Julian calendars (both of which follow the cycle of the sun and the seasons).

Instead, the date for Easter is determined on a lunisolar calendar similar to the Hebrew calendar. The First Council of Nicaea (325) established two rules, independence of the Jewish calendar and worldwide uniformity, which were the only rules for Easter explicitly laid down by the Council.

No details for the computation were specified; these were worked out in practice, a process that took centuries and generated a number of controversies. In particular, the Council did not decree that Easter must fall on Sunday.

In Western Christianity, using the Gregorian calendar, Easter always falls on a Sunday between 22 March and 25 April inclusive, within about seven days after the astronomical full moon. The

just fix it in time? following day, Easter Monday, is a legal holiday in many countries with predominantly Christian traditions.

Eastern Christianity bases its calculations on the Julian Calendar. Because of the 13-day difference between the calendars between 1900 and 2099, 21 March corresponds, during the 21st century, to 3 April in the Gregorian Calendar. Easter therefore varies between 4 April and 8 May on the Gregorian calendar. Also, because the Julian “full moon” is always several days after the astronomical full moon, the eastern Easter is often later, relative to the visible moon’s phases, than western Easter.

In 725, Bede succinctly wrote, “The Sunday following the full Moon which falls on or after the equinox will give the lawful Easter.” However, this does not precisely reflect the ecclesiastical rules. The full moon referred to (called the Paschal full moon) is not an astronomical full moon, but the 14th day of a calendar lunar month. Another difference is that the astronomical equinox is a natural astronomical phenomenon, which can fall on 19, 20 or 21 March, while the ecclesiastical date is fixed by convention on 21 March.

In addition, the lunar tables of the Julian calendar are four days (sometimes five days) behind those of the Gregorian calendar. The 14th day of the lunar month according to the Gregorian system is figured as the ninth or tenth day according to the Julian.

The result of this combination of solar and lunar discrepancies is divergence in the date of Easter in most years Soooooooooooo.... good luck fixing it in time!

Autumn - that Autumn, the time of the year where the days are getting shorter and the mornings colder.

The word Autumn is coming from old Etruscan. In essence, it is also denoting ‘harvest’.

The harvest of things we typically find in Europe. Cabbage, potatoes, celeriac and so on.

But also fish, like herring to be caught (fat nice one’s after a good summer in the Baltic) and salted. Pigs to be slaughtered and salted and stored.

Preparing for winter, really.

But where did the word ‘fall’ then come from? well, it might be something like ‘fall of leaves’ or ‘fall of season’. It was a great term in the 16001700 in England. The settlers of North America took that along; hence ‘fall’ is the common term in USA, not as much Autumn.

Autumn is also claimed to be an unhealthy season. Full of melancholia.

Summer is gone. The only thing that will change now is winter. Cold and wet. Inward focus is the word. A lot of poetry talks about this.

special season What autumn is surely famous for is the foliage changing colour. North America and Europe are the places most well-known, but it is really found wherever the trees are shedding their foliage.

To go see these rather fantastic sights is now a tourism industry (it had to be), especially in New England. ‘Leaf peepers’ is the term for this industry.

Japan is another place. The area around Kyoto and Nikko are famous areas for this. It is apparently a very long-standing tradition in Japan and is a part of a cultural setting. On top of, there is also a tradition to go to the Oze plain to see the grass changing colour. Very nice, really.

Let us just look at Leaf Peeping in the US. Is it big? Is it a lot of money?

Well, it is $3 billion a year industry for (mainly) New England. That is a lot of money.

I have some info from a website (https://skift.com/2014/10/19/leaf-peeping-tourism-is-a-3-billion-business-in-new-england/#1) whether relevant or not. It says that Vermont had some 3,6 million tourist in Autumn.

Massachusetts had some $2,8 billion in 2013. And it is probably not getting less.

New Hampshire’s leaf peeping season is major. With 9 ½ million people tourists, it is the second most important revenue earner. The state has an online foliage tracker at www.visitnh.gov/vacation-ideas/Foliage-Tracker.

Japan is also on the map: This is copied from http://www.pressat.co.uk/ releases/japan-the-leaf-peepers-paradise-afa54f0b6cf7535402c3bb78f050a151/

Autumn- a symp It’s all about the seasons in Japan. The spring cherry blossom is well known and documented, but it doesn’t get much more spectacular than autumn. With beautiful weather and vivid colours, this is one of the very best times to visit the country and InsideJapan have created a new Self Guided Adventure to get the most out of it....and it’s not all about the leaves.

Koyto is the autumn equivalent of spring’s hanami (blossom-viewing): a chance to admire the reds and golds of the changing leaves. From the gardens of central Tokyo to the mountainsides of the Japanese Alps, the leaves brighten up any scene from late September to early December. People head to their favourite autumn leaf spot to admire the beauty of nature and the spectacular colours on display... but the autumn is not just about the leaves.

phony in colour World Heritage leaves Beyond Nikko’s impressive Toshogu temple complex which celebrates the Autumn Grand Festival with Yabusame horseback archery (October 16-17), the leaves around the mountain top Lake Chuzenji are impressive. The bus ride back down the Irohazaka winding mountain road provides some of the most impressive foliage flanking the 48 hairpin bends National Park leaves Japan is 70% mountains and Kamikochi national park has some of the most impressive with the Azusa River cutting through towering peaks covered in Japanese Maples. Kamikochi begins to close to visitors with a blessing ceremony on November 15th as the snow begins to arrive.

Festive Fall Kyoto is home to thousands of temples and gardens, each transformed by the vermilion leaves of Autumn and there is plenty of accompanying traditional festive fun. The huge Jidai festival celebrates the citys history (October 22) with the Shichi-Go-San childrens festival taking place all over (November 15) and Autumn Geisha dances also celebrating the season (November 1-10).

CONCLUSION Autumn need not be depressing. There are a lot of things to do. And we can also go look at the grass changing colour!

The month March is such a funny month. It is starting to be cold in the morning. But it is not really winter. It is hot during the day, but it is not summer.

March is the first month in autumn (see that little gem of an article).

But what do we celebrate in March?

There is one little funny thing with March (wiki again of course): “March 1 began the numbered year in Russia until the end of the 15th century. Great Britain and its colonies continued to use March 25 until 1752, when they finally adopted the Gregorian calendar. The fiscal year in the UK continues to begin on the 6th April, initially identical to 25 March in the former Julian calendar. Many other cultures and religions still celebrate the beginning of the New Year in March” And us? Well, government fiscal year starts 1 April. Ever wondered why? I think we can have a guess now. I never knew that!

March is of course St. Patrick’s day – the Irish national day on 17 March.

That is big all over. Especially in USA. Earth hour – That is something different.

Earth Hour is a worldwide movement for the planet organized by WWF. The

h of March

event is held worldwide annually encouraging individuals, communities, households and businesses to turn off their non-essential lights for one hour, from 8:30 to 9:30 p.m. as a symbol for their commitment to the planet.

It has grown to engage more than 7000 cities and towns worldwide.

Today, Earth Hour engages a massive mainstream community on a broad range of environmental issues.

Earth Hour will be held March 25 in 2017.

Sometimes Easter is also in March, but leave that for now

Radiostations i “Radio is King” it says somewhere. And it is probably also true. But have we got something beyond the usual one’s we listen to? Let us look at the stuff we have on the ‘buttons’: (PS: all of this is from Wikipedia).

5FM: 5FM is a South African FM radio station that follows a Top 40 music format. 5FM broadcasts nationally to a youth audience. Its payoff line is “The Power of 5” YFM: “Youth” radio station in Johannesburg. Established in 1997, the station is formatted to mostly play urban music genres such as Kwaito, Hip Hop, and R&B along with a minority of its airtime being dedicated to talk shows.

Metro FM: Well-known. Been around since 1986.

Power FM (also known as Power 98.7 FM) is a South African commercial radio station based in Gauteng. It started broadcasting in 2013.

But what about the others? The more exotic one’s? Let us see: Smile 90.4FM is a South African private commercial radio station based in Cape Town East Coast Radio, also known as ECR, is a KwaZulu-Natal commercial radio station with an audience of approximately 1.5 million. It is one of the largest regional radio stations in South Africa.

Capricorn FM is the first commercial radio station in northern province of Limpopo in South Africa. It got into it in 2007.

in South Africa Cybatar is a tech startup company headquartered in Pretoria. The company was founded by Phiwa Nkambule in October 2014 as a social network, but has pivoted since that time and has been involved in the development of other startups. Cybatar Tune is one of them (I think).

RadioActive Rock: The station primarily broadcasts music in the rock, heavy metal, and alternative rock music genres.

Radio Hartklop: Afrikaans gospel.

Lesedi FM: The station broadcasts in all nine provinces, but greatest penetration is into the Free State (47% of adults) and Gauteng (32% of adults).

Heart 104.9 FM is a 24-hour music radio station, situated in Greenpoint, Cape Town, known as Cape Town’s Beat. Heart FM listeners have strong family ties, are socially aware and committed to enjoying life to the full.

Tru FM is a South African commercial radio station based in the Eastern Cape.

The station is unique in the SABC PBS stable as it is the only station primarily targeting the youth with two languages of broadcast, IsiXhosa and English.

There are many more. There are a lot of provincial one’s broadcasting in other officila languages, but I think we safely say that there is one for all!

Good listening

Mind Palace: A Me Here is something I stumbled across when I was doing research for exam tips: Mind Palaces. I have never heard of that, so obviously getting on to Wiki to see what this is now all about.

It is a well-established technique for remembering information.

Information in this respect can be anything: deck of cards, decimals of Pi, formula, letters and pronunciation of Russian alphabet, etc.

The information can be simple or complex.

The technique is to commit to long-term memory the information and an association to a physical object or location (hence it is also called Method of Loci). If you can see the object with your ‘inner eye’ you can recall the associated piece of information.

That is simple enough, I should say.

So what objects or locations can be used?

Walk through your bed room (in your mind) and remember objects. The favourite trophy is a good one. That trophy I can always remember, because it was given to me for an outstanding achievement in grade 1. My very first trophy. The circumference of a circle is 2r * pi.

Look at the trophy and repeat the formula. Store it in long-term memory – the brain will do that for you. Next time you need the formulae, you walk through your room, looking at the trophy and bang, there is the formula recalled!

I wrote ’31 April 1652’ on my white board. It is a very silly joke and when-

emory Technique ever I look at that I associate it with zebras. Their stripes are individual and no two zebras look the same. And zebras identify each other as they can see the patterns.

Are these examples weird? Well, they are real.

Here is the next big leap in this: Create your own ‘palace’. An entity entirely in your own mind, populate the rooms with curtains, colours, furniture, anything you like. Associate ‘things’ with the items (and the locations). Even create different palaces for different topics (e.g. palace 1 for maths, palace 2 for history, palace 3 for ..).

It is also possible to ‘construct’ in your mind the roads leading to the different palaces and to associate things to these.

You get the picture?

I think it takes a bit of practice, but I will try it out.

Is it new stuff? The roman senators (Cicero the most famous one) used this technique 2,000 years ago. Tried and tested as they say in the classics.

Oh yes, is it widely used?

Have you ever heard the term ïn the first place .. and in the second place ...

Where do you think it is coming from?

Just goes to show ... in the first place!

China building artificial isla What? And where is the South China Sea anyway? And is it not a part of China? I mean, it is called South CHINA sea? Isn’t it?

Well, if we look at the map, we can see that China is actually claiming the whole lot. And that means that all other nations are to stay out.

An international tribunal has ruled against any Chinese claims, but China has said they are not going to respect that ruling.

Let it also be said: about 60% of the world population is living in Asia.

If we also look at it, the China Sea is not like deep. It is not like Titanic deep. Actually so shallow so it is possible to build an islands pretty fast.

And that is what China is doing. With airstrips and military installations and all. Although they claim there is no intention of militarizing the islands.

But why?

Fishing rights is one thing. More than 8% of world-wide fishing catches are in the China Sea. And that feeds a lot of people. China needs it.

But so do the others!

ands in the South China Sea More? Yes: oil. But this is tricky. Nobody really knows how much there is. If anything. OK, there probably is, but is this the only thing?

Maybe the other reason is the real one: Nearly all Chinese imports is coming through the South China Sea. It is a ‘choke point’ for China. Anyone who would like to be ‘nasty’ to China has an opportunity here.

It is called global security. And as we may close our eyes to military matters, these things are reality.

not Iraq either, is it?

In the event China can militarize the island chains, it is hard to just ask them to go home if an international court should find them in breach of international law. What if they just say “no”. Who is going to go to war against them? This is

So, again. Possession is 90% of the law. And that is where the island building becomes a big problem.

It is more than just building on existing islands (like the Spratly’s or the Paracel’s) and all of tht is disputed anyway. This is about building artificial islands from scratch. Those islands have never been there before. So who is the owner? And should they even be there to begin with?

China building artificial isla It is complex because international law typically recognise a territorial limit of 12 miles from shore. But what if there is an island out there? A rock for that matter? 12 miles out from that one and we hit an artificial islands. 12 miles further out and we hit another rock and so on. Do we get the picture?

Obama was not happy about this at all.

One thing is to protect the sea lanes leading to one’s homeland.

Another matter is the option of excluding all other nations from sea lanes feeding other nations. That is called blackmail and other nasty things. Is this reality? Maybe.

So what is USA doing? Sailing war ships up to the islands is intimidating, but can it stop anybody?

Hardly.

USA has flown big B-52 bombers around the islands. They are also claiming ‘freedom of navigation’ but that is hardly a deterrent.

The new Trump administration is sitting with a big problem now.

The new secretary of state (foreign affairs) Tillerson has stated that USA should block access to those islands. ““We’re going to have to send China a clear signal that first, the island-building stops and second, your access to those islands also is not going to be allowed.” This is serious stuff.

The big question is now: what’s next?

ands in the South China Sea Is it a threat to world peace to have China sitting on the sea lanes across the South China Sea? Not in itself, but it is another flash-point that might just erupt one day. Why have more of these?

IS USA bluffing? Can they even stop access to the islands? The bad thing about a bluff is that one day someone might call your bluff and then you are finished. Unless you pull the six-shooter and do Wild Bill Hickok.

In the current situation, USA can probably block access to the islands. But then it is a serious escalation of the conflict with China and that is not good. US trade with China is a precarious one as China is holding tons of US bonds.

So, it is much more than just a military adventure.

And what if China should call the bluff? Is US prepared to have shooting war? If not, it is a bluff. And a bluff can be called!

Is this how the end begins? Both have nuclear weapons and no fear of using them.

Nanotechnology: w Remember we had an article on Nanotechnology? Well, it is some moons back, but it did spell out the basics and a lot of potential. This article is trying to bring you an update. Has something happened in the last many years?

Just to recap: Nanotechnology is ‘engineering at the atomic, molecular and supra-molecular scale.

In essence, we can now put singular atoms together to form new material sor whatever we want. And better, we can design ‘structures’ that can do things. i.e. a drive, a motor, a delivery mechanism for medication, and so on.

It is a field with a lot of potential but very few serious applications yet. The examples come across as on the fringes of real industrial scale acceptance.

Golf balls can fly straighter, socks not smelly, sun screen, etc. All well and good, but the real test is: Industrial scale acceptance and manufacturing processes.

Let us look at an example on this.

Carbon fibre. Carbon fibre is typically applied with a brush and then the whole thing is ‘baked’ in an oven to go hard. Of course carbon fibre is harder than steel and much lighter. But someone needed to see the real potential.

Suddenly race cars got made of carbon fibre. Aircraft wings, modern cars have tons of carbon fibre elements, and so on. General acceptance and a part of real-life industry.

where are we now?

But is nanotech there yet? Maybe not. It is hard to come across something that is ‘real industry’ yet.

There is one area where we might see something common: Molecular self-assembly. Wiki defines it as: “Molecular self-assembly is the process by which molecules adopt a defined arrangement without guidance or management from an outside source”. OK, this needs unpacking.

Micro-chips are in essence manipulation at a very low scale, but there is a limit to what can be achieved with the usual technology. In comes self-assembly. Now we can design what we want to have done and we can start the process where the self-assembly takes place without guidance (as in a machine manufacturing every component).

The other areas depending on nanotechnology working are nanowire and carbon tubes. Now e are talking real stuff where the goal is to reduce the size of the typical microchip and increase both speed and ‘bandwidth’.

Will nanotech Let us just look at it. Why is it important to get my spreadsheet to go faster? It is not about the spreadsheet. It is something else. We cannot get to code self-learning systems and self-modifying systems with the current computer speed. We need to get into a quantum leap here. It is not an improvement of a few percentages needed. We need computers to go 1,000 times faster – this year – and another million times faster next year.

What do we want to do? Well, driver-less cars, robotics, air travel (flights) and everything else. Now we see the potential here.

The DNA computer is a reality. DNA is assembled and used not as a carrier of information (as in biological system, e.g. humans) but as computational devices.

This is one of the things we are aiming at. And in my opinion one of the most significant things. Never mind the golf balls flying straighter or the socks not smelling.

The other breakthrough might be in medicine. The potential is to remove the need for surgery as this is rather invasive. How can it be done? Applying the right tissue-repairing set of molecules, etc.

The great thing is that these molecules can be broken down by the body after their mission is com-

ever deliver? pleted. That means we need not pollute our body with foreign substances.

Nanotechnology is the enabling technology for ‘wearable electronics’. Anybody who read our article about future clothing will see that clothes will be interwoven with the consumer electronics we know.

The cell phone will be a part of the ‘jersey’. The screen will be HUD displayed by the clothes, etc. but it will only be possible via nanotechnology.

Of course the military is interested in this new technology.

Recent research shows that nanoparticles can group together when hit by impact. Sort of an instant bullet proof vest. Another one is colour-changing clothes. So a new soldier can put on a uniform that will transform him or her into a chameleon-like person. Blending in.

Very smart.

There are other things coming up.

And there are other usages already but again, these are a bit on the fringes of heavy industrial applications.

Advise: give it another few years. But the computer industry will drive this one. My prediction.

Wasting food: w On a daily basis, most people tend to simply focus on themselves where everything they do affects them only. This is especially what is thought to be the case with food wastage.

According to the World Resources Institute (WRI), about onethird of all food produced worldwide, worth around US$1 trillion, gets lost or wasted in food production and consumption systems.

Individuals happen to be part of those production and consumption systems. One kilogram of potatoes produced by a farmer who survived the drought can be a three day serving for at least two people. However, we find people buying excess amounts of potatoes where some will go to waste. The supermarket packaging of potatoes (in this example) may not suit a family’s consumption. And even worse: the specials! Buy x kg of potatoes at only Y and save Z. So we buy it (because we ‘save money’). Then two weeks later, some of those potatoes are found in the garbage.

Growing food allows you to have your own ‘eat by’ date and it makes a vital difference.

On the surface of all the hard work, growing your own food has a collection of benefits to everyone and the

what a waste! rest of the world. Growing food means less cost for a household and less lost to the garbage which then translates to a decrease in the stats of food wastage.

Should we then grow all the veggies required? Maybe not. Setting aside a piece for say potatoes, spinach and onions and buying carrots in the shop will still help a lot (carrots from the garden have a tendency to be attacked by insects-Hard to grow).

The misconception is that saving food means buying minimal food or giving away food before it rots.

The quest is to produce food on a suitable scale, on a scale that will make one person feed a household.

That is not at the expense of the general society after consumption.

In a world that is food insecure, growing food simply means contributing to a decrease in the wasted food that could have fed the 795 million undernourished people around the world who suffer from hunger ‘.

“Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life”. (World Food Summit, 1996) and Growing food is a major contribution to food security.

A great conspiracy

Here is my favourite conspiracy. The suppression of free energy.

It goes like this: It is possible to have ‘free energy’. By utilising some physics, it is possible to generate electricity out of nothing.

How is a bit obscure, but never mind that.

It is suppressed by the oil companies and the governments around the globe because if we should utilise free energy, we would not pay for oil and so on. In essence, we would not have to pay for anything really, because there would not be a cost in producing things. It is all for free.

If it is all for free, the capitalist world will sink and take all rich people with it. They will be poor.

That is why the suppress ‘free energy’ and that is why we do have to pay for everything we consume and for petrol as well.

Wonderful!
