I try not to think about the weight of single graphene too much.

If I do I come up with a 1 metre wide sheet that wraps around the earth 33,000 times before it weighs 1 tonne.

A 1 metre wide sheet for 1 gram would need to be 1.315 km long.

So when you see a CVD sample at 4cm by 4cm for say $100 you know it's rather expensive per tonne.

About 10 mins in to the video



NR was referring to the half gram nanene sample which was being passed around room in a "pot".

Scaling up he said that 1 tonne would take 38000 conventional oil drums to store.

[wr63] 28/7/2018 17:49

Neill has clarified this at some point. Single layer graphene would require 38000 barrels, a figure NR said in a presentation he gave a couple of years ago. There is a video of that somewhere. He has since said Nanene GNP's have a different bulk density so requires far less barrels than the above figure.The bulk density is on the Nanene technical specification sheet.

pc joe - if it is a myth, it is one that ceo himself initiated.

[pcjoe] 28/7/2018 17:33

Yes 5-6 litres per 1 kg of Nanene - so much more manageable than the squillion barrel myth that refuses to go away for some reason

New Continental Port Plus Compound Update


Durability or Economy?

Don’t compromise

The main causes of extensive abrasion and extended wear
of harbor vehicle tires are interlocking stones and rough
concrete or asphalt surfaces. These can be heated by sunlight
to very high temperatures. In its structure the new Continental
Port Plus Compound was developed to noticeably reduce tire
wear and heat development in container-handling applications.
Characteristic of the Continental Port Plus Compound is
its outstanding resistance to wear and tear. This was achieved
through the use of high concentrations of natural rubber and
a special carbon black.

The result is exceptionally high mileage even under very hard
conditions. The natural rubber gives the rubber compound
outstanding resistance against the formation of cracks, even
at the highest deformations. Nevertheless, under severe
conditions, microcracks can occur. These are the smallest
forms of damage that can only be observed at high magnification.
In this case the special carbon black comes into play.
Its special structure prevents the propagation of microcracks
and thus the formation of larger cracks.
To avoid negative effects to the tires’ live span and in order
to counteract the abrasion caused by aggressive surfaces, a
special synthetic rubber was added to the Continental Port
Plus Compound. Through its strong interaction with the
carbon black, it is responsible for the exceptionally strong
abrasion resistance of the compound.

Economy or Technology?

Don’t compromise

If you had to design the perfect tire, the goal would be something
like this: “Unrivaled traction on wet and dry surfaces, in
searing hot and freezing cold conditions. Zero wear, extreme
stability, and a comfortable soft ride on any surface. And the
best of all – the costs would be next to nothing.”
Although this exaggerated scenario is still a long way off,
Continental’s V.ply technology is in fact a huge leap forward
in the quest for the perfect tire. Our V.ply design was inspired
by racing tire technology and executed through the extensive
use of 3-D modeling and the Continental Group’s Research &
Development know-how. It was also extensively field-tested
in real-life conditions.
V.ply technology combines the best of cross-ply and radial-ply
design by integrating an innovative weaving pattern of
multiple cords arranged at specially designed angles.

Economy or Reliability?

Don’t compromise

ContainerMaster+ DockMaster+

The requirements of reach stackers, heavy forklifts, and empty
container handlers are manifold. While lifting and stacking
containers, they need to move with the agility of a compact car
and the steadiness of a tank. And still they have to be reliable
and economical in the process.
These vehicles handle enormous loads on single axles.
Potholes and uneven surfaces can cause the vehicle to tilt.
When handling such a container, the vehicle can become
unstable, which increases the risk of an accident.
All in all, reach stackers, heavy forklifts, and empty container
handlers require tires with exceptional load capacity,
high stability, and outstanding maneuverability for smooth
and efficient operation in order to maximize their operating efficiency.

Economy or Durability?

Don’t compromise

CraneMaster

At first glance, harbor cranes and AGVs don’t seem to have
much in common, but when it comes to tires, their requirements
are pretty much the same. Both vehicles operate only
at moderate speeds around gradual bends. With both vehicles
the tires have to carry enormous weight from two sources
– firstly, the weight of the payload and secondly, the weight
of the machine itself. Additionally, there is the turning on the
spot or at extreme angles, which puts tremendous stress on
the tires. Along with high durability, it is the rolling resistance
of the tires that has to be considered since it has a significant
influence on energy consumption.

In summary, harbor cranes and AGVs require tires with exceptional
load capacity, outstanding maneuverability, and low
rolling resistance for optimal operation at their full potential.


Safety or Economy?

Don’t compromise

StraddleMaster+

Straddle carriers are the ultimate high-tech wonder that
combine height, weight, speed, and maneuverability in the
terminal yard. However it is exactly these important characteristics
and the extreme operating demands that place high
levels of stress on the tires, which can lead to premature tire
wear. In fact, premature tire wear is only one issue but – safety
is another. For this reason, the damping properties of the tires
are crucial – only a tire with the necessary and correct stiffness
can prevent the slip-stick effect and its serious consequences
yet also provide driving stability in a controlled and safe manner.
All in all: to use a straddle carrier to its full potential, tires with
optimum deflection properties plus outstanding maneuverability
and braking capability are essential.


Speed or Safety?

Don’t compromise

TerminalMaster Terminal Transport ContiRV20 ContiRT20

There’s no vehicle in the port that clocks up more mileage than
a terminal tractor. This means that its tires have to accelerate,
brake and corner more often than any other kind of tire in the
port. They also have to operate in an environment that accelerates
tire wear and hastens tire failure. Uneven surfaces with
different and sometimes highly abrasive surfaces, potholes,
bumps, and foreign objects are just some of the reasons.
No wonder that only a fraction of all tires used on terminal
tractors reach the end of their projected service life. But it’s
not always the environment that ends the life of a tire ahead
of schedule. Since a vast number of tires just aren’t designed
for use on terminal tractors, sometimes it is simply a case of
the wrong tire in the wrong place.

Agility or Defensibility?

Don’t compromise

SC20+ ContiRV20 Trailer Terminal Transport TerminalMaster

It doesn’t have to transmit steering forces – all it has to do is its
job. The requirements of a tire used on a terminal trailer may
not be remarkably high, yet if a tire on a loaded trailer fails,
the consequences can still be very serious. Moreover, terminal
trailers have to operate in an environment that accelerates tire
wear-out and tire failure by way of uneven or highly abrasive
surfaces, potholes, and bumps. Not to mention foreign objects
being thrown up by the tires of the terminal truck ahead. So
it’s no surprise that some tires used at a port don’t reach the
end of their expected service life. But it’s not always the port
environment that shortens the life of a tire. It is often merely
a case of the wrong tire in the wrong place, causing it to fail
well ahead of its projected service life.

The description in that data sheet includes the word "tapped" .What does tapped mean in this context?



About 10 mins in to the video NR says that 1 tonne would take 38000 conventional oil drums to store.

If this is the case then the platelets must be arranged in a very haphazard manner. We have heard that nanene does not travel well. Presumably this is because there will be a tendency for the nanene platelets to settle and clump together.

[serratia] 28/7/2018 16:13

You eliminate transport issues by making master batches. If the customer is going to use Nanene in a composite with polymer X at a 1% loading you supply the Nanene ready mixed in polymer X as say a 50% batch. The customer then dilutes it down to 1%.
In that example you reduce the volume 50 fold.

[baz99] 28/7/2018 16:11

Kilgallp, Ax

Think I have the answer (probably) -

Taken from the Nanene data sheet at

Bulk density = 185.7kg/m3

So 1000Kg is approx. 5.4 m3, or 5400 litres, or around 33 barrels

Happy to be corrected.

Cheers

[baz99] 28/7/2018 15:34

Hi Ax,Yes had read that post and followed the discussion previously, hence the apparent discrepancy. Will try to find out moreBaz

[grabster] 28/7/2018 15:28

Woolybanana - the 3 tonnes production capacity, as I understand it, is 3 tonnes per year - which over 240 workdays would average 12.5kg per day. Presumably at Cheltenham. Presumably supplying initial samples, follow-up samples, and some not-too-distant producers. (including Aac Cyroma?)

And it was described as a maximum - which I presume might come on stream in stages?

[rogerbridge] 28/7/2018 15:22

Well said SG.

Those scumbags pick on shareholders who are often elderly investors and have little desire to respond or engage them.

Some BS because they like to BS for their own self importance. Those are easy to deal with, just ignore them.

Then other BS and seek to cause harm to others with such BS for their gain. They come in all shapes and sizes and in my book are about as low as it comes.

The sort that when they get caught red-handed go into lie over-drive to try and save their ass.

All can BS until their heart is content but if you damage others in the process then don't expect others to just take it on the chin and walk on. Complacency is always a weak point for such folk.

Baz - see Grabster's 21889 post:

"If theoretical volume of monolayer graphene sheet per tonne is 38,000 barrels (as stated by NR), 3 tonne capacity is 114,000 barrels".

KilgallpAt the investor day Neill had a flask of approximately one litre and, from memory, said it contained around 80g of Nanene (I was sitting next to Super and Spike so they can correct me if I am wrong)So, 1000kg would be approx 12000 litres or 75 barrels if my maths is rightCheersBaz

Sorry woolybanana, I don't know the answer to your question. I can think of a few scenario's that could possibly supply the answer, but as it would be pure conjecture on my part, I shall not put them into print.

There are various people on this site, who have greater VRS knowledge than I, perhaps they can respond to your query.
