Scientists Predict Green Energy Revolution After Incredible New Graphene Discoveries

The study, published in the journal Nature, shows that graphene and a similar single-atom material called boron nitride allowed the build-up of protons on one side of a membrane, yet prevented anything else from crossing over into a collecting chamber.

In their scientific paper, the researchers speculate that there could be many applications in the field of hydrogen fuel cells and in technology for collecting hydrogen gas from the atmosphere, which would open up a new source of clean energy.

“It’s really the very first paper on the subject so what we’re doing is really to introduce the material for other experts to think about it,” Sir Andrei said.

“It was difficult not to speculate. If you can pump protons from a hydrogen-containing gas into a chamber that doesn’t contain anything, you start thinking how you can exploit this?” he said.

“One of the possibilities we can imagine, however futuristic, which has to be emphasised because everything has been shown on a small scale, is applying a small electric current across the membrane and pushing hydrogen though the graphene or boron nitrite membrane,” he explained.

“Essentially you pump your fuel from the atmosphere and get electricity out of this fuel, in principle. Before this paper, this wouldn’t even be speculation; it would be science fiction. At least our paper provides a guidance and proof that this kind of device is possible and doesn’t contradict to any known laws of nature,” Sir Andre added.

Graphene is tough, about 200 times stronger than steel, yet incredibly light. It is considered the first two-dimensional material because it forms sheets of crystal that are just one atom thick.

It is also an excellent conductor of electricity, so is useful for anything involving electronics, such as bendable mobile phones and cameras, and wearable electrical devices attached to clothing.

Sounds too good to be true.

and its as simple as filtering water over a sheet..et voila, hydrogen to power our fuel cells....at no energy cost to extract.

We are minted.

Oh noes, you need an electric current to make it work...damn, thought we have invented the perpetual motion machine.

Presumably the current is provided by solar say and your battery has water in it to start with and highly combustible hydrogen/oxygen after.

However, the hydrogen/atmosphere thing is somewhat confusing. Doesn't sound right.

The atmosphere is only 0.000055% Hydrogen and very high up.

It's probably a story of storage rather than 'new fuel'.

I gather Hydrogen doesnt exist in nature on Earth on its own...it combines with something else.

Hydrogen fuel proponents say their fuel cells are the ultimate clean energy...but of course, we need to get some which means using energy to separate it.

I gather the whole process from water to car is requires more energy to complete than you get back..obvious if you dont beleive in perpetual motion.

Well they tried to rubbish shale gas but it has sent oil prices down to $72.

Guess we have an unholy alliance of Greens , jihadists and despots that want the West to be held to ransom at $300 a barrel and old people freeze in their beds.

Just looking at the quoted part the actual quotes from the people who know anything about it don't appear to mention it as a source of energy at all, the "hydrogen from the atmosphere" part may well just be the invention of a clueless journalist who doesn't have any idea what they're talking about. The whole style of the headline (if it's the same as the topic line) is very tabloid which sets alarm bells ringing.

Lockheed skunk works announced recently they are working on a prototype fusion reactor which is small enough to fit on a truck. They claim in 5 years it will be getting used for military applications and within 10 it will be commercially available. Although its top secret stuff so they haven't released any data.

If the people developing this stuff dont end up dead or missing of course :)

Even better it's merely a "letter" and not a paper if this is the article in question.

That doesn't really mean much. Letters are used when you discover something that you want yo be the first to publish. They're shorter than and go through the peer review process a bit faster than standard papers.

Proton transport is how our mitochondria make energy, so I'd imagine that if we're going to make energy from this it's going to be along similar lines to that process. How that translates to boiling a kettle I've no idea.

Edit: thinking about it it's also how photosynthesis works. So this is massive.

Edit 2: looks like you can use this directly in batteries and fuel cells http://en.m.wikipedia.org/wiki/Electrochemical_gradient
