Dear Rainbow

Do you mean all those months ago when the share price was 60p-£1.

Yes there has been a lot of changes and new and exciting Rns since then !! and it looks like easily £2 per share by Christmas is very likeky .


So thanks for reminding us how lucky we all our to be in this share .
I do hope you bought in at the old levels or indeed recent levels as you have a lot of interest in Vrs it appears did you attend the AGM where many of your questions would have been answered ??
Happy lth

Here's a few comments from people reacting to the 2010 'graphene supercap breakthrough!' Pleasing to see vrs/gnano chiming with these hopes and right up there in 2018! Aimo. Best ellis

"Power electronics to handle a 50% + voltage drop should not be a major challenge. Inverters can be built to handle that and much more.

The real challenges are:

- high enough energy density
- quicker charge/discharge time
- lower cost.
- improved durability.

Graphene ultra caps (or batteries with similar technologies) could address all the above before 2020. That would mean the end of ICE cars and small trucks.

And;

"Most Graphenes are currently very expensive as are most new breakthrough technologies or materials. When mass produced, price will quickly drop. Both ultra capacitors and next generation batteries could make use of this material to achieve higher performances.

E-storage units will evolve much faster in coming years with more R&D and as demand multiplies. Price per Kwh will go down with mass production facilities in many countries.

The current decade may very be called the e-storage units golden years or decade. We will all be surprised at what will be available in 2020+.

Other new technologies such as high performance 3D TVs, low cost color e-books, higher performance lower cost solar cells etc may be overshadowed by high performance, highway capable, lower cost BEVs by the end of the current decade.

AND;

"This is REALLY BIG NEWS.

EVs were good enough with NiMh batteries.
86wh/kg is not that bad at all considering the features. Li-io tech is only between 150 and 250 wh/kg.

If this capacitor is comparable to other supercapacitors, then an EV with this would:
- Accelerate like a rocket (great power density)
- Never require battery replacement
- Regenerate 90% of braking energy

@joewilder
It seems that graphene will be cheap to produce:

Finally, quote from vrs acquisition rns re gnano:

"GNA, based in the Parque Cientifico Madrid, Spain, is a company capable of utilising Versarien's graphene products in an environmentally friendly, scalable production process for energy storage devices that offer high power density, almost instant recharging and very long lifetimes for use in electrical vehicles and portable electronics products."

Yes, or 30k at 178p

[anotherdrink] 03/10/2018 10:28

Dummy run via HL: Sell 50000 shares at 175.26p

[the fat controller] 03/10/2018 10:26

MM's will still take 50k, so demand is good.

[squire007] 03/10/2018 10:12

Are you colour blind ............. 'hello' ... anyone in .. lol

[ashehzi] 03/10/2018 10:11

Thanks rainbow for keeping us on ground. Thanks for reminding us we should not be high.

[rainbow23] 03/10/2018 10:09

Remind me again. What happened to the "ISO imminent" of many months ago,the China deal "by June" and the collaborations update "prior to the agm" Now the rampers are all looking forward to xmas and hoping that santa Neill will fill their sacks with £2 coins for their shares. I fear they're going to be disappointed once again. Meanwhile it's another red day for vrs.

[ashehzi] 03/10/2018 09:57

We are already beneficiaries of below initiative via 2 DIT employees:



Tens of millions of pounds of taxpayer money could be poured directly into the most promising UK startups, as Britain races to create the next global tech giant.

...

“I think the model we would move to next would be to think about co-investing alongside our partners or the angel syndicates. Given that we have a venture and growth focus we have been looking at those areas which are attracting interest and capital from the venture community, so artificial intelligence is a big feature and autonomous vehicles are coming down the tracks very quickly.”

Managed to track down the original science from 2010 that claims 'curved graphene (graphene oxide) sheets' is the key to producing gains versus conventional in supercapacitors. Because the curves stops the g.o layers sticking together (which means surface area is as large as possible, key to energy density and performance). Curved graphene cited by skeleton re their supercaps and in claire grey video. Of course, whether or not +nanene needs to be curved is immaterial, because obviously it gives superior performance versus conventional AND graphene oxide, else vrs would be using their own quality graphene oxide rather than nanene.

"Graphene-based supercapacitor offers energy density comparable to NiMH battery, but with rapid charge and discharge26 November 2010

Researchers from Nanotek Instruments and Angstron Materials have developed a graphene-based supercapacitor that exhibits a specific energy density of 85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C (all based on the total electrode weight), measured at a current density of 1 A/g. These values are comparable to those of NiMH batteries, the researchers note, but the new supercapacitor offers the ability to be charged or discharged within seconds or minutes. A paper on their work was published online in the ACS journal Nano Letters.

These are the highest energy density values ever reported with carbon electrodes without the pseudocapacitance contributions from a conducting polymer or metal oxide, the authors said, further stating that “We believe that this is truly a breakthrough in energy technology.”

The group, led by Bor Jang of Nanotek Instruments, reported in 2006 that graphene can be used as a supercapacitor electrode material. Despite a number of efforts to improve the specific capacitance of graphene-based electrodes, however, results fell sort of the theoretical capacitance of 550 F/g due to the high tendency for graphene sheets to re-stack together.

The team determined that the best strategy to achieve a high capacitance in such graphene-based electrodes is to use curved graphene sheets rather than flat sheets to prevent the sheets from sticking to one another face-to-face. The curved morphology enables the formation of mesopores accessible to and wettable by environmentally benign ionic liquids capable of operating at a voltage >4 V.

With the total electrode weight of a supercapacitor system being typically one-fourth to one-half of the total system weight, the system-level specific energy of graphene-based supercapacitors can exceed 21.4-42.8 Wh/kg, which is comparable to that of a modern nickel metal hydride battery used in a hybrid vehicle. This breakthrough energy storage device is made possible by the high intrinsic capacitance and the exceptionally high specific surface area that can be readily accessed and wetted by an ionic liquid electrolyte capable of operating at a high voltage.

With regards to "Bruno" and the fact that people were flying in from all over China to see Peter is it possible that given Neill's sense of humour Bruno doesn't actually exist but is a name given to the 100 or so DIT staff in China all banging the UK and VRS drum. There certainly seems to be a lot of leads coming in for just one person out there.

one for the future...a space elevator.

"The steel tether to be used in the experiment is too heavy to be used as a full-sized space elevator, which must, of course, extend for tens of thousands of miles. But a growing number of scientists, including Kaku, now believe that an ultra-strong carbon-based material known as graphene could be just the material needed. “On paper, it has the tensile strength to keep the space elevator anchored to the ground,” Kaku says of graphene, which ounce for ounce is 200 times stronger than steel."

Yeo PJ favors Jinan, to be the first ..... so lets wait and see :-)

[johnveals] 03/10/2018 08:48

I am not questioning the pros or cons of GO I am merely recounting what I am 100% certain happened at the AGM.

[diversification] 03/10/2018 08:32

Mike brenner and SG have addressed this oxide situation. Getting boring now.

[johnveals] 03/10/2018 08:27

I can confirm that at the AGM NR did state that competition from Chinese Graphene Oxide was a concern.

[haz101] 03/10/2018 08:22

If only I’d knew about VRS when I visited nasa Ellis lol

[ellissj] 03/10/2018 08:20

Nasa patent here for rgo and metal oxide supercap ! The ideas are out there. But i wager the performance gain using +nanene is a head turner ! Aimo. Glalth. Best ellis

[squire007] 03/10/2018 08:18

Ramp morning.... lol
I will stick to my 250p by xmas theory ......... :-)

[rockraven] 03/10/2018 08:14

spotted this tweet yesterday among replies to Times journalist Ian Cowie

"UK govt recently seconded 2 senior DIT officials to work with Versarien for a year. Unprecedented. Must be something special brewing. Peter Jay (15 August) and Matt Walker (22 May). Boss Neill Ricketts at 10 Downing St twice so far. America's NGA want him to address senate."

[owenga] 03/10/2018 08:04

Can't wait!

[superg1] 03/10/2018 08:02

Owenga

He's right, I do my research.

Gawd knows what's going to happen once Herald and Miton are out. If we then hit China or other news there is not a lot left to supply anyone.

Charts will go out of the window at that point imo, it will be fund ride.

[a_game] 03/10/2018 07:59

haha :) providing a distraction from the other chat on here! Focus on the prize ;)

[owenga] 03/10/2018 07:58

Your such a great ramper a_game.. lol
