shanghai-maglev.tower.jpgGerman steelmaker ThyssenKrupp is threatening to let China have the Maglev technology that powers the world's fastest train.

principles of magnetic levitation (Maglev) have been known for seven
decades and huge sums have been spent developing the technology.

to date it has only been used in one commercial train line, at
Shanghai's Pudong airport, where it transports people to the city at
speeds of up to 430 kph.

ThyssenKrupp developed the Transrapid
train with fellow German engineer Siemens. Not surprisingly, they want
Germany to also have a Maglev train, to link Munich to its airport — a
long and tedious 40km journey, as I can testify.

But officials
have been bickering about the Munich project, particularly its cost —
€1.8bn. The Pudong train cost around $1.2bn and is unlikely to ever
recoup the investment.

Tired of waiting for the Munich go-ahead
and with no other prospects of Maglev sales on the immediate horizon,
ThyssenKrupp is prepared to cut its losses and sell the technology to China, according to Germany's Deutsche Welle. ThyssenKrupp's CEO Olaf Berlien says:

18 months, ThyssenKrupp will decide whether the technology will go to
China. The Transrapid will then be a German-Chinese project which would
mean a technology transfer to China.”

represents a big about-turn on the Germans' original strategy when they
zealously guarded the Maglev technology for themselves.

added that the deal could involve selling the technology to China,
founding a joint venture in China or setting up a distribution or
marketing partnership with a Chinese firm.

To further inflame passions, ThyssenKrupp argues that the row may tarnish German's high-tech image abroad.

issuing ultimatums is rarely a good negotiating tactic, but clearly
ThyssenKrupp is worried that the window of opportunity for its
technology is closing. Japan has a variant on the technology based on
superconducting magnets, but most worrying for ThyssenKrupp is China's
home-grown maglev technology, which uses permanent magnets.

to build a pilot maglev line using China's own permanent magnet
technology were announced this summer. The 3km-long line is in the
development zone of Dalian.

The Peoples Daily, not surprisingly, claims China's home-grown maglev technology is technically superior and costs 50% less than those of foreign competitors.

its not ready yet. And faced with the choice of sinking huge sums into
developing its own technology or buying a tried-and-tested one —
offered at a suitably attractive price — the logical choice would be
the latter.

But to date, China has shown little interest in
using logic to formulate national technology policy – take the debacle
over China's much-delayed 3G wireless standard TD-SCDMA, for example.

Maglev has impressed many western visitors to China, not least Henry
Blodget, the disgraced former internet analyst, who wrote about his Maglev experience on a recent China fact-finding trip in Slate.

Fear not, Blodget was not out there to pump Chinese internet stocks — he has been banned from Wall Street for life.
