The air up there

Did you know altitude makes a refrigerated container, or "reefer" run a little hotter?

The higher the altitude, the lower the atmospheric pressure, which affects the compressor chilling the reefer. This means a reefer unit set at -25°C at sea-level in Cape Town or eThekwini may only reach -18°C to -20°C in Johannesburg under load.

Arriving with the load a few degrees Celsius over the specified miminum temperature will see the load rejected.

Ockert Cameron

Ockert Cameron, founder of and driver at The Frozen Food Courier, has a handy guide that shows what capacity loss to expect in South Africa's three major cities:
- Johannesburg (1,750m): ~15-18% capacity reduction.
- Bloemfontein (1,395m): ~13-15% capacity reduction.
- Pretoria (1,330m): ~12-14% capacity reduction.

Cameron, who drove over 770,000 km across South Africa for his Frozen Food Courier company, advises container fleet operators to ask reefer suppliers specifically about altitude performance. Reputable suppliers understand this issue and can recommend appropriately-sized units.

Crunch time for apple exports

Reefers tapping power of the generators Agbiz installed at Cape Town port.
Container drivers and fruit farmers in Western Cape are now waiting to see if this year will be better than the costly 25/26 fruit export season, when some 1,688 reefers got delayed in Cape Town.

This resulted in a lot of expedited work for container drivers. Fruit exporters reportedly spent over R135 million to double the container volume sent to Gquberha harbour.

About them underwater aliens


Dear you 
My letter about the beached whales raised more questions than answers so I'm writing this to warn you: Stay away! 

I get that making contact with the few thousand zombies who made their home in the Mariana Trench would be world changing, but trust me all you still-breathing people, coming here will not end well for you, or your equipment.

Your drones and diving bells will fail because the old reptiles don't want contact; and your divers will die because we do.

With "the old reptiles" I don't mean those old zombies sitting immobile for months in what I call the Main Moan, nor do I refer to us young ones who still go up and about to refresh our cemetery signs and scavenge supplies. 

While we zombies are apex predators, we are not the most dangerous entities you have to worry about down here. Luckily, the ones you do have to worry about avoid contact, so I'll get to them next. 

Before them, let me explain why you have to first worry about the second most dangerous entities down here.

We are not that many, only a few thousand, but we are in every meaning of the word, super human. It comes with the pressure. As the saying goes, what doesn't kill you makes you stronger and since we are already undead, the enormous hydrostatic pressure that causes widespread necrosis and cell lysis in living tissue, just forces our molecules and cells closer together, making us a little stronger every day. 

According to one paper on the subject I tried reading while up scavenging, the immense hydrostatic pressures down here "alters tertiary and quaternary protein structures".

I didn't understand most that paper but I can tell you what "a forced decrease in molecular and cellular volume" looks like down here. 

It looks a lot like a garden gnome. 

Go ahead. Laugh. 

It is what I did when I met my first really old zombie. Ur is what it calls itself and it barely comes up to my knees.

Ur is an "it" because sex is the first thing to go when you die and after a few millenia down here having your body squashed by the full weight of the Pacific Ocean, your average human body ends up in a size best described as "gnome".


When I first saw him I thought if you give Ur a red hat and a little fishing rod, he would be a shoo-in as an extra in the next Gnome movie
. I was only laughing on the inside at this thought but I swallowed even my mental smirk when Ur picked up a fist-sized metallic nodule and proceeded to squash it like a stress ball without showing any effort. 

That was how I learned that zombies become stronger as they get smaller. Think hydraulic yellow machine strong. Which is why the really old zombies still call submarines and deep sea diving bells “packed lunch”. 

I call divers "liquorice"... a bit rubbery on the outside, but with a delicious salty-sweet taste on the inside, once you start chewing. 

See, small as human brains are, it is still our best-tasting source of the glucose that keeps as sentient. Whale brains are bigger than human brains, but in taste, whale brains are salted pork while human brains are honey-glazed fat, ready to melt on your tongue. 

But I digress. Back to them who don't want to make contact yet. 

They are small, biped reptilians who have been quietly evolving in air pockets under the ocean in the 66 million years that passed after most of the other dinosaurs went extinct.

All dinosaur survivors have this in common: their ancestors could hide underwater while things burned on land. The ancestors of these theropods must have found large air pockets, and when their fellow survivors went back topside after the smoke had cleared, they chose to stay. As time went by they first found then later made more air pockets for their nurseries while the adults lived increasingly ambitious amphibious lives as far from the surface as possible.

Obviously, only the cleverest survived to breed.

Now fast forward many, many millions years to that unknown point in time when the first zombies discovered that a combination of cold and unrelenting hydrostatic pressure makes the best combination to keep our bodies from decaying.

Mix a need to be as far from the top as possible with a need for deep, cold water and you get why we met up with the very clever reptiles down here in the Mariana Trench. For those shy reptiles, no place is further from the surface than this deep gash in Earth's crust; and for us undead, no place offers an icier embrace.

We meet the clever reptiles only rarely though, when they open their hatches to flit to the top in their flying saucers; or to pick up more of the ancient polymetallic nodules that litter the deep ocean beds, the same nodules that Ur likes to use as stress balls. 


We never speak. Instead, we relate with them much like you do with other intelligent animals. For the little reptiles certainly are intelligent – I rate them the cleverest species on Earth. But it is a cleverness as alien as that of any octopus, their mimicking minds as quick as any of the corvids and the cherry on top -- they are more telephatic than even elephants. 
Which is why we think at them, instead of speaking to them. These thoughtful conversations are still very much hit and miss. 
Gregory Bateson, the old "dolphin whisperer" on whose underwater machine I'm typing this, said it is like trying to communicate with octopuses that think in colour, or with crows that pack several layers of meaning in one squawk, or elephants that tap into the subsonic. 
Our delicious human frontal lobes just ain't designed for such dialogues. 
If all this makes the wee reptiles sound very civilised, be warned: They ain't.
Not that they are barbaric, I mean, they use the hydrothermal vents down here to make their very advanced metallurgic alloys and have algae producing oxygen in their comfortably warm nurseries. But theirs are old, cold-blooded thoughts on top of reptilian habits that are quite disgusting. And this is coming from me, an undead creature that will suck out your brains through your nostrils.  
Most of my disgust comes from how these very clever little amphibious reptiles breathe and breed underwater. To breathe, they do like turtles, sucking water into their cloaca, in which two specialized sacs lined with blood vessels absorb oxygen. Think of it as a big wet fart, but in reverse. To breed, they join arse to arse in a “cloacal kiss”, the male transferring sperm to the female using the same muscular contractions that excrete waste. 
For them conceiving, breathing and excreting all use the same sack. They really are supremely efficient creatures and their metallurgy is a wonder, but now the little power light on Greg's underwater typing machine have started flashing red, so I better get back to the main point: Don't try to find us.
Not us zombies, nor the clever little reptiles that you call "underwater aliens".
We will eat your brains and as any of the many sailors and pilots who saw the clever little reptiles or their flying craft will tell you, they avoid contact with humans. 
From what Greg could deduce, this is because the primitive, hot thoughts from living humans give the telephatic reptiles something like the brain freeze you get from eating ice cream too fast. Greg made a living trying to talk to dolphins in the hallucinogenic 1970s, so his guess is more educated than most.
But I'm not going to beg.
Those of you who insist on trying to find us, please come. I have a powerful hankering for liquorice that needs sating. 


Yours,

Zohm Bieh

Two different paths for electric truck buyers

Watch this Huwaei electric truck port in Beichuan can dispense up to 800,000 kWh. 

The giant BYD company from China and the tiny Edison Motors company from Canada offer two different plans for diesel truck owners looking to go electric.

The engineers at the giant BYD company aim their plan at fleet buyers and provide the entire electric ecosystem supporting electric trucks, from finance, to battery banks for 1,5 MegaWatt chargers, to different sized trucks and vans.

This system has been proven for trucks of all sizes in China, from vans to dryage trucks to a fleet of electric coal trucks served by a giant electric truck charging port in Beichuan, which is able to dispense up to 800,000 kiloWatt-hours to waiting trucks.

Grow your own

Save on high food costs by planting your own. 

As all drivers know, expensive diesel means expensive everything else, especially food. Which is why now is the time to have the family start a food garden back home.

Got no space for a big vegetable garden back home? Check out how the Garden of Life project recycles old tyres, plastic bags and 2-litre bottles to create micro gardens that feed entire families in Boitekong in the North West, Kanyamazane in Mpumalanga, Mamelodi in Gauteng and Strandfontein in the Western Cape.

Volvo's truck builders mark 20 years in Mzansi

To build up to 14 trucks a day at Volvo assembly plant in KwaZulu-Natal, South Africa, the line has to move every 35 minutes -- except when it's birthday time. 
Volvo Trucks South Africa on 19 August briefly stopped the assembly line to celebrate 20 years of building what most drivers rate as the strongest trucks at the assembly plant in Umbogintwini in KwaZulu-Natal. 

Plant director Vuyo Sabata and over 160 men and women who build up to 14 trucks a day at the plant, were on hand to welcome Stuart Potter, MD of Volvo Trucks South Africa from Johannesburg; Per-Erik Lindström, Senior Vice President of Volvo Trucks International from Sweden; and councillor Cyril Xaba, mayor of eThikwini, among several VIPs who attended the event.

Smart birds hint at very clever dinosaur ancestors


Current (and lowest common) thinking is that dinosaurs were dumb, despite living and evolving for 165-180 million years in the not exactly user-friendly environs that was the Mesozoic era. 

This thinking neglects to add that long, looong after those after-effects of a big meteor had wiped out the big 'uns, their tiny, obviously very intelligent, problem-solving, song-making, sentient-proven avian survivors added another ~60 millions years, which they continue to do to this day.
