Funding
for Efficiency
by Peter Easton |
A utility based in Atlanta has pledged
funds to support an energy efficiency program in its four-state service
territory. The Southern Company said it will help fund the efforts of
the Southeast Energy Efficiency Alliance over the next three years.
"The Southeast is the fastest-growing region in the nation, which
offers tremendous opportunity to foster green buildings and clean industries
to compete in world markets by using energy wisely," said Marilyn
Brown, a professor of public policy at the Georgia Institute of Technology
who chairs the Alliance. "By engaging with regional energy leaders
such as the Southern Company, SEEA seeks to make energy efficiency the
most important resource to meet growing energy demand in the Southeast."
In 2006, the Southern Company invested more than $73 million to promote
energy efficiency through its operating subsidiaries. Coupled with energy
efficiency programs for customers, this investment has lowered costs to
consumers, reduced overall energy consumption, helped protect the environment,
and eliminated the need for the company to build an additional 2,800 megawatts
of new generating capacity.
Southern has 4.3 million customers and more than 42,000 megawatts of generating
capacity.

Complex
Dewrinkler
by Jean Thilmany |
Take your average ironthe domestic
one. While the iron might not seem like a complicated product, its design
includes detailed geometric contours and intricate internal mechanisms.
Engineers at Rowenta, a home appliance manufacturer in Erbach, Germany,
wanted to reuse digital iron components in their varied CAD designs to
avoid having to redesign the same part again and again for each new product.
For this, they turned to their upgraded NX CAD software from UGS of Plano,
Texas. UGS has recently upgraded NX to version five. Although Rowenta
has been using NX for 16 years, the engineers appreciate the reuse capabilities
included in the new version, according to Ralf Kremer, the company's
CAD manager.
The upgrade gives users direct access to the UGS product lifecycle management
application, Teamcenter. It also enables companies like Rowenta to reduce
rework by giving engineers a library tool that displays standard parts
and reusable content. Engineers browse existing folders and directories
for the company's standard parts, catalog parts, and designed parts,
which they can include in their own designs.
Another feature lets users drag icons of parts to the model and automatically
positions them.
Klaus Reining, manager of information technology at Rowenta, said that
engineers there appreciate the reusability features.
"We began developing components as parametric models whose dimensions
can quickly be adjusted to fit newer products," he said. "At
the same time, we began building parametric assembly models that automatically
update to match a change to one component."
Maybe it would help to think of all the technology that goes into your
simple household appliance the next time you set up the ironing board
with dread for the task ahead.

Geothermal
Says
It's Under- estimated
by Alan S. Brown |
Is the United States missing the boat on
geothermal energy? The Geothermal Energy Association certainly thinks
so. In a report titled An Assessment of Geothermal Resource Development
Needs in the Western United States, the trade group calls geothermal
"an underestimated, underreported, underexplored, and understudied natural
resource."
Report author Daniel Fleischmann said that the U.S. geothermal industry
has nearly 60 projects capable of producing more than 2,000 megawatts
in the pipeline. If they all reach completion, they will double U.S. domestic
capacity.
Fleischmann said another 150,000 megawatts of near-term capacity is possible.
This is equivalent to an estimate of U.S. geothermal resources by the
U.S. Geological Survey in 1978. Fleischmann said that the 1978 survey
vastly underestimated the technology's potential.
The report considered only conventional hydrothermal reservoirs shallower
than 3,000 meters with water temperatures greater than 150°C. Fleischmann,
on the other hand, noted that some geothermal projects tap reservoirs
down to 6,000 meters, and others use water at temperatures as low as 72.5°C.
The range of possible resources has also widened. According to Fleisch-
mann, researchers believe they can extract electric power from most oil
and gas fields by tapping geopressured hot water, natural gas, and hot
wastewater reservoirs. He sees geothermal potential for power and cascaded
heating for alternative fuel production, aquaculture, greenhouses, and
mineral and vegetable processing facilities. Geothermal resources can
also be used for heating.
The Geothermal Energy Association calls for several policy changes. They
include extension of the production tax credit that makes alternative
fuels more competitive; incentives for geothermal distributed generation
and direct use projects; more funding for the Department of Energy's
Geothermal Technologies Program; more interagency coordination on transmission,
environmental, leasing, and permitting issues on federal lands; and a
new survey on geothermal resources.
According to the U.S. Department of Energy's Energy Information
Administration, total U.S. generating capacity was 978,000 megawatts in
2005. If the United States develops all 150,000 megawatts of geothermal
potential, it would be equivalent to 15 percent of current U.S. capacity.
Fleischmann writes that if it all 150,000 megawatts came online by 2015,
it would provide about half the new energy demand of the 13 states that
make up the Western United States.

Profibus
Approaches 20 Million Nodes
by Peter Easton |
Sales of Profibus nodes, the networking
system for manufacturing plants and machinery, are on track to exceed
20 million by 2008.
That's the assessment of the umbrella organization representing
25 regional Profibus offices around the world and more than 1,400 member
companies.
By selling 3.4 million Profibus nodes in 2006, according to PI (Profibus
and Profinet International), the number of units installed worldwide climbed
to 18.8 million, remaining on track to reach the 20 million mark forecasted
for 2008 by the group in 2004.
According to the industry, Profibus suits the majority of process applications
because they often require process instruments and discrete functionality
to run side-by-side.

Jets
on Electricity
by Harry Hutchinson |
A technology company based in Gibraltar
has entered an agreement with Delta Air Lines to develop a system to use
electric motors to move jets under their own power on the ground with
their engines off.
Current methods of moving aircraft across airports are to tow them with
an external vehicle or to use the thrust of the main turbines. Using the
turbines burns much more fuel than is needed to roll an airplane at taxiing
speed.
Using the aircraft's auxiliary power unit to drive electric motors
would free the airplane from relying on a tow vehicle, and would consume
less fuel than using the turbines. A system using the APU and electric
motors would also generate less noise than using the plane's big
turbines.
The system, developed by WheelTug plc, uses electric motors in the nose
wheel so pilots can back planes away from gates without a tow tug and
taxi to a remote point before starting the turbines. After landing, the
pilot can turn off the jet engines and switch power to the motors.
WheelTug demonstrated a proof of the concept in 2005.
A representative of Delta said design issues include questions of economics.
Adding the system will make a plane heavier, so it will require more fuel
to fly. The system must be powerful enough to move a commercial jet and
light enough so it does not cost too much of the fuel it is intended to
save.
According to a statement by Delta, approval of the system is expected
in 2009.
Delta said the agreement gives it the option of deciding whether or not
to go into the business of installing and maintaining WheelTug systems
for itself and other airlines. Delta is already running a maintenance
business that serves more than 100 customers. The airline also said it
has warrants to buy as many as 600,000 shares of WheelTug at $36 per share.

ASME
Goes to China
by Harry Hutchinson |
An office representing ASME in India is
due to open in Delhi on July 1. ASME has contracted a consulting company,
Tecnova India Pvt. Ltd., to conduct market research and to operate the
office for the Society for the next three years.
Tecnova will look at opportunities in India to sell ASME products or services,
and will expand relationships with various organizations and institutions
in the country, including the Indian Institutes of Technology, the Federation
of Indian Chambers of Commerce and Industry, and the Confederation of
India Industry.
India has become a major force in global engineering. The Society believes
that ASME is widely known in the gas and oil sector there, and sees opportunities
to become established in other key areas of activity in India, including
nuclear power and biotechnology.
According to John Corcoran, ASME's managing director, services,
the current plan is that, after three years, Tecnova will turn over operation
of the office to the Society. At that time, the India office staff members
are expected to become employees of ASME.
The Delhi office will be the second major initiative launched in Asia
by ASME this year. The Society announced in late February that it had
received approval to establish a company, ASME Asia Pacific LLC, to conduct
business in China.

Hartford's
Hybrid Bus
by Peter Easton |
New England's first zero-emission
fuel cell-powered hybrid bus made its debut last month in Hartford, Conn.
The 40-foot transit bus began its run on a free downtown shuttle route.
In a few months, it will move to other routes that serve the capital city
and surrounding towns. This will be done to meet the project goal of testing
the bus in all types of typical transit service, including low and high
speeds, and routes with steep grades.
CT Transit and its project partners will analyze data on fuel economy,
maintenance costs, and reliability.
According to UTC Power, which provided the fuel cell power plant, benefits
of the bus include zero harmful tailpipe emissions, along with smooth
and quiet operation and fuel efficiency that is expected to be two times
better than a standard diesel-powered bus.
"The people who live and work in Hartford and the people who visit
the city are not only going to enjoy riding this quiet bus, but also will
like the fact it emits nothing but water vapor, making for cleaner air
for all of us to breathe," said Jan van Dokkum, UTC Power's
president.
A $2.9 million grant from the Federal Transit Administration to the Greater
Hartford Transit District funded the bus and infrastructure to support
this and future fuel cell transportation projects in Greater Hartford.
UTC Power has provided fuel cell power plants for fleet transportation
since 1998.

Cavitation
Testing
by Harry Hutchinson |
A standards-issuing organization, ASTM
International, wants to hear from engineers who have an interest in cavitation
erosion testing.
The organization's Subcommittee G02.10 on Erosion wants to hear
from people who have used ASTM Method G 32 for cavitation erosion testing
or have used any other cavitation erosion, or liquid impingement erosion,
test method (for example, ASTM G 73 or G 134). The group says it also
wants to hear from anyone who has a concern with cavitation erosion as
a field problem or research topic.
People who fall into any of these categories should send a note with a
brief explanation to Frank J. Heymann, the task group chairman, at 25
Thornton Way, No. 205, Brunswick, ME 04011, or by e-mail to marseah@gwi.net.
The group says the objective of this effort is to help determine the degree
of interest in, and importance of, cavitation erosion test methods at
the present time. People who get in touch with the subcommittee will receive
a followup questionnaire, according to Paul A. Swanson, the subcommittee's
chairman.

Helicopters
Receive
$13 Million Upgrade
by Peter Easton |
One of the original pioneers of aviation
has won a hefty contract. Curtiss-Wright Corp. of Roseland, N.J., through
its motion control segment, received a contract from Sikorsky Aircraft
Corp. for the supply of RAST probes to be fitted on 28 of the H-92 helicopters
destined for the Canadian Maritime Helicopter Program. Valued at more
than $13 million, the contract includes design, development, testing,
and delivery of production probes for the helicopters.
The helicopter probe is required to interface with the shipboard RAST
system provided by Curtiss-Wright to the Canadian Department of National
Defence. RAST is a helicopter handling system that integrates all of the
functions required to safely operate and stow large ship-borne helicopters.
In addition to enabling safe launch and recovery, RAST facilitates the
securing, maneuvering, and hangaring of helicopters, day or night, even
in adverse weather and high sea state conditions.
The RAST system is used by a number of navies around the world, including
those of the United States, Canada, Japan, Australia, Spain, and Taiwan.
The helicopter-installed probe forms an integral part of the securing
and handling system by providing the structural attachment point between
the ship-installed RAST system and the aircraft.
Work for this contract will be performed at Curtiss-Wright's facility
in Mississauga, Ontario. RAST Production deliveries are scheduled to be
made from 2008 to 2010.
Sikorsky is in Stratford, Conn.
