Gale Group PROMT is a multiple-industry database that provides
broad, international coverage of companies, products, markets and
applied technologies for all industries.
It is a 'one-stop' database whose versatility and size enable you to
research a product, its markets, the materials used to produce it,
competitive products, regulatory issues and other factors that
impact on a company, industry or business.
PTSP contains information on virtually all manufacturing and service
industries, from computers, electronics and telecommunications to
chemicals, food, pharmaceuticals and finance; marketing; advertising
and public relations; aerospace, defense, and commercial aviation;
international, specialised business and industry newsletters; and
full text coverage of press releases announcing new products and
technologies, mergers and acquisitions.
PROMT offers expert opinion and insider perspective. Its extensive
source and subject coverage and highly specific indexing make PTSP
an essential database for effective business and industry awareness.
The database includes abstracts, excerpts and full text documents.
The number of full text documents has increased to around 65%.
Use PTSP to answer questions like:
- what international governments have purchased Northrop's AN/ALQ-
171(V) electronic counter measures system?
- what announcements have been made recently concerning mergers
and acquisitions between UK companies in the consumer electronics
industry?
- what are the forecasts for coal production in Europe?
- what have been the latest developments in solar calculator
technology?
- what have been the recent trends in the French yoghurt market?
- what information is available on the applications of Abbott
Laboratories' new blood-test kit, Auszyme Monoclonal?
Sources:
PTSP contains 1,100 active international trade and business
publications, plus archive sources. All documents from non- English
sources have the bibliographic details translated into English and
approximately one-third of these contain an abstract in English.
Sources covered include business and industry, newsletters,
newspapers, government and agency reports, research studies,
investment analysts' reports, corporate news releases and corporate
annual reports.

Converting residual heat from car exhaust fumes into
electricity could cut fuel consumption and reduce carbon
emissions. Siobhan Wagner reports
Researchers in Germany are developing a thermoelectric
generator to convert the heat from car exhaust fumes into
electricity. The device will feed energy into the car's
electronic systems and could cut fuel consumption and help
reduce the vehicle's CO2 emissions.
A thermoelectric generator creates voltage when there is a
different temperature either side of it. So the greater the
temperature difference, the more current the generator can
produce.
A team from the Fraunhofer Institute for Physical
Measurement Techniques is developing new thermoelectric
materials, modules and systems to harness this kind of
residual heat.
'The temperature in the exhaust pipe can reach 700degC or
more,' said
Harald Bottner, head of the Thermoelectric Systems department.
'The temperature difference between the exhaust and a pipe
carrying engine cooling fluid can thus be several hundred
degrees,' he added.
The thermoelectric converter will make use of this huge
differential. With the flow of heat from the exhaust fumes on
one side and the cold side of a coolant pipe on the other, the
charge carriers will pass through special semiconductors and
produce a current similar to a battery.
Bottner said thermoelectric effects were first recorded in
the 1800s, but thermoelectric materials have not significantly
improved in efficiency since the 1950s. 'During the last
decade there have been many efforts to increase the quality of
materials, using new developments in nanotechnology and
additional knowledge about the physics behind thermoelectric
material,' he said.
Inadequate efficiency was one of the key factors preventing
such materials from being used in cars, but new developments
mean this is no longer the case.
Earlier this year, for example, researchers at Boston
College and MIT in the US demonstrated a boost in the
efficiency of bismuth antimony telluride - a semiconductor
alloy commonly used for thermoelectric cooling. By breaking
the bulk material into tiny chunks - from five to 50nm across
- the researchers increased a key measure of thermoelectric
conversion, called the ZT of the alloy, from one to 1.4.
Bottner said the thermoelectric generator technology will
not be ready commercially for another five years. But with
many people concerned about rising fuel costs and CO2
emissions, he added, it cannot come fast enough.
Bottner said most drivers do not realise that two-thirds of
the fuel consumed in their car is emitted, unused, as heat.
Approximately 30 per cent is lost through the engine block and
a further 30 to 35 per cent as exhaust fumes. Any way to
harness the unused waste heat could significantly lower the
car's fuel consumption. The technology could also be applied
to other machines and even power stations.
The long-term objective for Bottner and his team is to
reduce dependence on alternators - the generators currently
used to provide electricity in cars - and to use
thermoelectricity to supply energy to the ever-rising amount
of electronic gadgetry.
Thermoelectric generators could step in and cover a
significant proportion of these requirements, but in no way
replace alternators entirely.
'It would not be possible to get rid of the alternator,'
said Bottner. 'A standard car consumes about 5kW of electrical
energy while driving, while a small car will consume roughly
about 1kW. We hope to produce a generator that could produce
about 1kW.'
The most important feature of thermoelectric generator
technology, however, could be the fuel savings. 'This could
make it possible to cut fuel consumption by between five and
seven per cent,' claimed Bottner.
