FYI, the use of
rare earth elements has very little to do with «green tech», it is a common requirement for everything that is usually called «high tech».
The growing shortage of
rare earth minerals underscores how truly difficult the transition to a clean energy economy will be.
Featuring massive 40 mm drivers with
rare earth magnets for superior sound, these headphones offer incredible dynamic range, especially when it comes to mid-range definition.
Hi Guys, I noticed quite a few comments
about rare earth magnets here and there are some things that seem misunderstood with regards wind turbines.
Featuring a pair of 45
mm rare earth drivers that deliver superb sound, the closed ear design results in an audio reproduction that has repeatedly been lauded by critics and users alike.
The company says a geared solution is more efficient, uses a lot
less rare earth materials and will need to be serviced less often compared with a direct drive turbine.
By lowering the use of
expensive rare earth metals, the cost of the new batteries has been reduced by about 30 percent.
Investment in
physical rare earth metals is not a feasible option for many investors, but there are several ways to gain exposure to this asset class.
Or remove mountains of rock to mine low -
grade rare earth mineral deposits for solar panel films, hybrid batteries and turbine magnets?
Moreover, what makes it possible to accomplish the toughest of jobs are its variable speed trigger,
rare earth magnet motor, metal reinforced housing and all - metal drive train.
Wind and solar power also mean there is a sudden demand for tons of
rare earth elements that weren't terribly important a decade ago.
The whole slew
of rare earth elements are a challenge to separate because of their chemical similarity — and they are never found alone.
The Ministry of Industry and Information Technology has cut China's target output from
rare earth mines by 8.1 percent this year — alongside cooling measures for other commodities, including polysilicon — and is forcing mergers of mining companies in order to improve technical standards.
China has scrapped quotas
on rare earths exports and will probably replace them with a resources tax.
Much more likely is a scenario in which Lynas will have to make an additional commitment to safety, and will start its Malaysian refinery — which could eventually put out 22,000 metric tones a year — in one or two months (every month of delay costs Lynas $ 10 million) and make sure
rare earth supply increases even further.
Northern Minerals has attracted a Chinese - based funding partner to provide up to $ 49.5 million for its flagship Browns Range heavy
rare earths project near Halls Creek.
Strong attractor But, in large part, magnets drive the growth in demand
for rare earths such as neodymium — swelling by 15 percent per year, according to an analysis published in Science — and dysprosium.
Former
rare earths market darling Lynas Corp is deep in talks with its largest bondholder about a potential debt - to - equity conversion for which it will seek shareholder approval in November.
But it's also home to 93 percent of global production of so -
called rare earth elements — including two metals essential for a wide array of green technologies, from hybrid cars to wind turbines.
«Your iPhone doesn't work
without rare earths in there,» said Mark Smith, chief executive of Molycorp.
With prices of neodymium still rising and
rare earths exports from China dropping by 30 % in 2010 as it keeps more of the metals for its own electric car industry — the world's biggest — , Toyota's work seems perfectly timed.
ASPIRING
rare earths miner Arafura Resources is on a renewed push to progress its Nolans project in the Northern Territory and has set a date for mid-next year to decide whether to continue or walk aw
Northern Minerals»
heavy rare earths project at Browns Range in the East Kimberley appears to be timed to perfection following last week's shock announcement of production cut backs by China.
Another way Molycorp tries to stay afloat while
rare earths prices are falling is by being a vertically integrated neodymium (used for magnets) supplier.
I would suggest we give a good long studied look into the energy production values of how a magnetic spinning disc could generate energy uinto a generator similar to the ones that wind turbines are generating but with higher friction values for higher electric output from the powerful spin that can be caused
by rare earth magnets in specific allignments
«There is no single military system in use by the Pentagon that does not
contain rare earths,» King notes, ranging from Abrams tanks to radar systems.
By 2015, they hope to be at full production, producing 18 million kilograms of various
rare earth oxides a year.
A leading Chinese
rare earths research centre has played down the threat that Beijing could cut export quotas of the strategically important elements.
