But how many volts? 2.7? (can't watch Youtube here)

you haven't missed much.
No proper information in the presentation:
no info on removing excess liquid before inserting into DVD reader
no info on what the laser did
no info on what you ask the laser to do for or to the liquid
no attachment of electrodes
no creation of the two layers
no insulating layer between the two layers
no charging information.


Some of the comments imply they were lying about what they actually made.
Some comment about one atom thick layer, but the presentation showed them pouring copious quantity of liquid onto the (blank?) DVD disc

Are you serious? I suggest you watch it again without any preconceived bias or prejudice, try to comprehend it and when you do,all will be revealed.

Rooster, are you getting some of this information, like 240v and other data from somewhere other than the video you linked? because I just watched the video, and in the three minutes it was nothing more than the sort of thing you see on a morning happy news show on TV. generalities and predictions of benefits.


They predicted pulling an electric car into a recharge station, and recharging in a few seconds. But since cars run on energy, not voltage, how much current must that charger supply to fill a super cap in those few seconds. What keeps the battery leads from melting? etc etc.

The 240v info and everything else is in the series of videos on Youtube that I mentioned? I think your getting things mixed up eg;charging a car in a few seconds? I think it was 15 minutes? It was the LED that required a few seconds and ran for 5 minutes🙂

did the link you posted show how to attach leads to the capacitor?
did the link show how to charge the capacitor?
did the link show how much voltage and/or current was required to charge the capacitor?

Did the link show anything useful?

Why have the WEC and F1 apparently abandoned capacitors for holding the energy needed for the next acceleration?
We have battery, capacitor and flywheel technologies and all seem to be moving to battery.

I don't know the answer to my question, because they don't tell us for fear of giving their competitors an advantage.

Thats one way of looking at it but if you look at the chemistry,the physics and the videos on how to make your own graphene and your own supercapacitor/battery or energy storage device as they call it now, you will have a better understanding of the implications of this discovery.By the way the inventor didn't patent the discovery so that big oil cant hold up production with years and years of patent disputes.

amazing, how few people can understand what is being said.

thanks, redrooster, for posting this.


been looking at ways to make a 'carbon antenna' .

this might help.

Supercaps are like batteries, for higher voltage you have to connect them in Serie.
Then add a kind of charge/discharge management system.
I've build last year an 28V supercap UPS using 400F ones giving 250W for 30 minutes.
For audio power amplifier I would use LifePO4 batteries with supercaps. But it isn't a cheap Development.

Anyone remember the 'Batacitor' (if that's the right spelling) from Philip Jose Farmers 'Riverworld' series?
It would be a very useful device as depicted...in other words, a device with all the attributes of a battery and a capacitor.
