However, for graphene to be the success story it is so often touted as, it first must be mass-produced at an affordable price.

But therein lies the problem.

Graphene centres, particularly within the UK, are still a relatively new concept - with the University of Manchester leading the charge in terms of graphene research.

'Fuel from thin air'. Can't be hype, surely?

Talk about desperation...

Graphene to drive next-generation fuel-efficient cars:
http://www.greenintelligence.org.uk/article/graphene-drive-next-generation-fuel-efficient-cars

Scientists from the University of Manchester are working on a new application for the wonder-material, graphene, to help develop more efficient vehicles by converting waste heat into electricity. The collaborative project between the university and thermal management firm, European Thermodynamics Ltd, aims to use super-conductive graphene to harvest the heat produced by motor engines and use it to recharge the vehicles battery or power other functions such as the air conditioning system.

Tinkering at the edges.

Diminishing returns on investment of new technology. At very best this would
reduce fuel consumption by 10% Even then it would produce more electricity than the car needed, so unless the car is a hybrid some of it would be wasted.

Probably a better use of graphine would be to use the material instead of steel for the car body, but it all comes down to cost.

(I can't find a figure for the electric consumption in a ICE car - it depends on how many gadgets , pumps, etc. are driven by electric motors as well as lights, radio speakers , resistive heaters etc. More in luxury models I assume).

Some interesting advances certainly, but not as world changing as is suggested.
Fuel from air seems a bit unlikely, liquid fuel from electricity, perhaps.

An improved light bulb, yes possibly but it is only a slightly improved LED lamp, every little helps but not exactly world changing.

More efficient vehicles by generating electricity from waste heat, certainly but the gain is very small and cost and complexity are increased.

More efficient vehicles by reducing weight, certainly but again only modest savings.

It would help if we used carbon fibre for vehicle bodies but even that is said to be too expensive. If it was costed over a longer life span that would probably reduce the cost considerably but that wouldn't do much for the mass production of cars which is where the real problems lie.

We need obsolescence in the production of STUFF to support mass manufacture and continued profit so things like carbon fibre and graphene, which will prolong the life of things that they are made from, will be kept very expensive for as long as possible.

Quote:
The centre will be partially funded by 15m from the Higher Education Funding Council Englands UK Research Partnership Investment Fund; 5m from Innovate UK; and 30m from Masdar - the Abu Dhabi based renewable energy company owned by Mubadala. The remaining 10m will be provided by other research funds and institutions.

Graphene could revolutionise nuclear power say Manchester scientists:
http://www.manchestereveningnews.co.uk/news/greater-manchester-news/graphene-could-revolutionise-nuclear-power-13006185

Scientists have hailed a crucial milestone for graphene after revealing the wonder material could be used to clean up the nuclear industry. Research carried out by the University of Manchester has shown graphene-based membranes could make the production of heavy water more efficient, leading to greener and cheaper nuclear power.

Heavy water - also known as deuterium oxide - is a key component within nuclear reactors. Its now hoped that graphene could be used to reduce carbon dioxide emissions associated with producing the liquid by up to a million tonnes per year. Writing in leading science journal Nature Communications, a team from the university said they could demonstrate scaled prototypes of graphene membranes capable of producing heavy water. The complex process involves separating hydrogen isotopes.

Because of graphenes unique material properties it has the potential to effectively separate sub-atomic particles, making the process more efficient and cost-effective, researchers said. Derived from pencil lead-style graphite, graphene is just one atom thin and was pioneered in Manchester by physicists Sir Andre Geim and Sir Kostya Novoselov. It has been hailed as the strongest and most conductive material in the world, with a huge range of potential electronic, material, and even medical uses.

The same group of researchers found last year that graphene could efficiently sieve hydrogen isotopes. Industrial opportunities regarding the discovery werent analysed because there were no membranes or fabrication methods suitable for scalable manufacturing. But the research group has now developed fully scalable prototype membranes and demonstrated the isotope separation in pilot studies. Dr Lozada-Hidalgo, a research fellow at the University of Manchester, said: This is a crucial milestone in the path to taking this revolutionary technology to industrial application.

The potential gains are high enough to justify its introduction even in the highly conservative nuclear industry. The research team estimates that by using graphene, more than one hundred times less energy would be required to produce heavy water. Sir Andre Geim, a professor of condensed matter physics at the university who won the 2010 Nobel Prize in Physics for his work on graphene, added: Tritium discharged both from nuclear power plants and as a result of environmental disasters is a major global concern. We believe this technology can economically transform the environmental footprint of future nuclear plants.
