How about "spudbat" or "womtater"?

[festario] 03/9/2021 16:05

Right, that's it.... I'm in.I'm officially a shareholder.I bought 12 of these golden tickets for a paltry four quid.I'm allowed to voice my opinion (again)

[fireball xl5] 03/9/2021 16:01

All those 1 share trades must equal something. Are those buses coming? See the ducks lining up?

[dudhew] 03/9/2021 15:07

Be patient or feel free to go elsewhere. You won't be missed here.

[adejuk] 03/9/2021 15:03

is this the four months of commercialisation?

[dil 21] 03/9/2021 14:58

All these uses and still no orders !

[yombo araka] 03/9/2021 14:51

Thank you, I'm glad you enjoyed it. I didn't actually consider naming it (I've just been referring to it as 'Potato Wombat') but I'd welcome any suggestions 🤔

[zoo keeper] 03/9/2021 14:43

YA
I’m very impressed indeed with your handy work!
Do you have a name for the potato wombat?

Thanks to CS and Marky for the links.

another instance where it pays to have graphene where its predicted the costs are much lower

GREI: Graphene-Reinforced Elastomeric Isolators Seismic Isolation of Structures

One out of three people in the world is exposed to earthquakes, and the number of people living in seismic areas increased by 93% in the past 40 years - 2.7 billion in 2018. Cities face a growing pressure from global challenge on resilience of structures and infrastructures to catastrophic natural events.

Seismic isolation is the most used technology to mitigate vibrations to buildings. This technology uses rubber-steel composite interposed between the structure and the foundations to divert the energy of the earthquake and to minimize interstory drift and floor accelerations of the above structure. However, while steel is needed to reinforce the composite, its presence limits the use of base isolation technology to strategic buildings such as hospitals and civic centres. This is because the current steel-based technology is heavy and requires engineered machinery to manufacture and cut it in bespoke shape and specialized manpower to install. To extend the use of this technology to houses and commercial buildings on a global scale, new materials for reinforcing rubber are required which will result in highly efficient, ultra-lightweight and low-cost seismic isolation devices.

Graphene-Reinforced Elastomeric Isolators (GREI) is a new ground-breaking technology exploiting the mechanical properties of rubber and a few-layer graphene to enhance resilience of structures, crucial to survive devastating seismic events.

Recently developed techniques such as transferring graphene on bulk materials (rubber) by spry coating and 3D printing have opened the frontiers of new advanced functional materials. GREI is made of alternate layers of graphene and rubber; it is shorter and lighter than commonly used steel-reinforced elastomeric isolator (made of alternate layers of rubber and steel shims) and therefore easier to transport and install. In GREI graphene deposition on rubber is achieved by an isopropyl alcohol (IPA) assisted direct transfer method (IDT). Specifically, a graphene film consisting of a random network of nanosheets is first deposited on a filter membrane and then transferred onto rubber by IDT due to IPA evaporation. Such advanced composite material is currently non-existent, and its development and implementation will boost the manufacturing industry, by opening the frontiers of self-build seismic metamaterials, ultimately resulting in saving human lives.

GREI scaled prototypes have been designed, manufactured and tested. Their unparalleled mechanical properties will push the boundaries of vibration engineering, envisaging mass productions and application in 1) earthquake engineering: where GREIs are (retro)fitted between the structure and the foundations to mitigate earthquake-induced vibrations 2) bridge construction: GREIs are used to accommodate movements due to moving loads and material deformations; 3) the marine industry: GREIs are installed between the hull of a vessel and its modules to keep oil/gas modules safe from impact and damage due to adverse sea conditions.

Graphene and rubber are both maintenance-free materials. The cost of a currently used steel-reinforced elastomeric isolator is thousands of pounds; whereas the cost of GREIs is predicted to be much lower at a few hundred pounds and there will be further cost reduction once a production line is implemented (manufacturing using 3D printing, transporting, installing and maintaining).

Well observed re Germanicus.Many other rabid bulls must be very close to that type of volte-face.I believe that December is pencilled in for the next stage.If anything comes from that, the estimate is a couple of years to reach an actual court.

What date is club sandwiches dance with Neill set for?

Ozette. Described as odd looking, lumpy and no set shape!

Cheers BB - I love this one - the outrage around the paid for 'certification' is particularly amusing:

Cheek212, London, about 22 hours ago
This is the worst researched article I think I've ever read! If they know anything about Graphene, then they would be telling people to invest in Versarien, the only company in the world certified as producing quality Graphene in commercial volumes. If QinetiQ have been testing Graphene for their products, then there is only currently one company that would be able to supply them! Directa plus and Applied Graphene Materials haven't even had their materials certified as being true Graphene - Versarien has! If you are going to write an article about the wonders of Graphene, make sure you give the readers the right information.

Performance since this article:
VRS -73%
AGM -36%
DCTA +52%

hope you have the new graphene mask!!!

[nellyb] 03/9/2021 10:38

Thats a scabby looking potatoe, what type is it?

[festario] 03/9/2021 10:33

Is this still a Mask company?That all went very quiet after the accounts were released.

Thank you, it's quite uncanny isn't it.

Yes I have actually .. all sorts of dross has been hitting double figures lately 🤔
