Oh man, that car is really smoking!

AUSTRALIA: May 22, 2001

SYDNEY - Hey dude, check out my hemp mobile!

Australian researchers believe that within a decade, cars could be 
made of hemp - the cannabis plant - as backyards and dumps overflow 
with rusty metal hulks and vehicle makers turn to biodegradable 
materials for car bodies.

Alan Crosky, of the University of New South Wales' Material Science 
and Engineering School, said yesterday that hemp had turned out to be 
the most viable material, beating coconuts and banana trees in 
preliminary studies.

"Disposal of old cars is a growing problem. It is only a matter of 
time before the expense of disposal becomes the owner's 
responsibility and the consumer is forced to pay the full life-cycle 
costs of their car," Crosky said.

"Because this will increase the cost of cars, developing an 
environmentally friendly material that can be used to make the bodies 
of cars is now a viable option," he said.

Crosky told Reuters he had begun researching hemp to find ways of 
making sure it does not become brittle and could protect the 
passengers of a vehicle during an accident.

He said hemp - made from the cannabis plant but containing only 
minute amounts of the narcotic tetrahydrocannabinol (THC) - was like 
fibreglass, but a natural product.

"It's renewable, you don't have to put as much energy into making it, 
and best of all, burning it doesn't get off anymore carbon dioxide 
than it absorbed during growing, what we call CO2 neutral," Crosky 
said.

Hemp is widely used in making textiles and rope.

Research was at the preliminary stage but Crosky believed it would 
not be too long before hemp cars became a reality.

"It might take a decade," he told Reuters.

Magnesium use in cars could double in five years

BELGIUM: May 22, 2001

BRUSSELS - Magnesium use in the manufacture of automobiles could 
double in the next five years as demand for lightweight, fuel-saving 
materials grows, a major industry conference heard yesterday.

Friedrich Schumann, Director of Vehicle Research for Germany's 
Volkswagen Group, told the International Magnesium Association's 
(IMA) annual conference that during the 1990s magnesium had made 
ground against other aluminium, plastics and steel-based alloys.

But if this growth was to continue more cooperation was needed 
between the magnesium industry and car makers, he said.

"Only by adopting an integrated approach to construction methods, 
materials and processes can lightweight construction be achieved at 
competitive prices," he said.

"While recognising that there is still some way to go before that 
integrated approach is achieved, we still view it as the key to 
greater use of magnesium in motor vehicles," he said.

Schumann said the main areas of magnesium use were in the drive train 
and vehicle interior but new applications would arise in the next 
five years.

"In the short term, the number of those applications will increase 
further, conceivably to double the present figure, and the first uses 
of magnesium in body components can be expected," he said, referring 
to a target of between 60 and 80 kg of metal per automobile.

However, more research was needed into new alloys.

A longer-term target of over 100 kg of magnesium per vehicle would 
not only depend on technological developments but also cooperation 
between the industry and users as well as successful cost reductions 
in the whole production chain.

These cost reductions had to address primary metal production, 
component manufacturing, in-house recycling and a secondary material 
market, Schumann said.
