Participantsof theWGC2010 exhibition apparently­
show their optimism andreadiness to accelerate thegeothermal­industry.
The WGC2010 exhibition hall features someof the cutting-edge technology currently applied­in and offered to the most demanding markets.
According to president director ofIndonesian­ Pertamina Geothermal Energy(PGE), Abadi Purnomo, Indonesia is not left
behind­ in terms of expertise. “We are capableof mastering the technology. We also havecompetent­human resources, whose expertise isindex

Japanese heavy industry giant, Mitsubishi­(www.mhi.co.jp), comes up with theimprovement­ of its turbine technology with asystem called Integral Shroud Coupling (ISB).
The new approach to the system offers a higher
load and smoother, less vibrating machine
which in theory results in higher yield.
“Our machine is capable to produce one
and a half time more load than the conventional
machine. Thanks to the advanced engineeringsystem, it has less vibration and therefore offersa more reliable and long lasting operation,” said

Another Japanese giant industry, Toshiba
Corp. (www.toshiba.co.jp/power), offers its
Japanese state-of-the-art technology thatenables­ the company to acquire a substantial
share in the global geothermal market. “Amongour approach is the smooth and more reliablethus high-yielding machine, famous all over theworld,” said Akihiro Taniguchi, manager of theToshiba Geothermal Plant engineering.
France-based Cryostar SAS (www.cryostar.com), a company focusing on the newly
developed­ system called the super-criticalbinary technology, offers a cutting-edgeengineering­ expertise. The binary is suitable
for low temperature wells. “Normally it works
well where the temperature is or less than
200o Celcius,­” said Frederic Marcuccilli, Ph.D,
manager­ of Cryostar Power Plant Engineering& Development.
“The advanced system, instead of applying­direct steam, utilizes circulating propane athigh pressure, giving overall a better power
production,” said Mr. Marcuccilli.
Baker Hughes (www.bakerhughes.com),
one among leading geothermal companies,
promotes its newly developed high-power
Electrical­ Submersible Pumping (ESP) system.­­The ESP is capable of surpassing 1,000day run times in a well with 315oF (157oC)
temperature.­“The system will artificially help to lift more
liquid to increase more production,” said Paul

capable of maintaining stable performance athigh well temperature at greater depth.
Managing Director of the Asia Renewable
Pte. Ltd., Edward McCartin, said that many companies still rely on the nodding donkey (traditionalbeam pump system) widely used in many countries aside from the current turbine technology.
According to Edward McCartin, although
theoretically the nodding donkey produces
only fifty percent of the turbine (due to thesimple pump’s simple up and down movablesystem), the traditional machine is still widelyused in many areas, like in China.
In certain circumstances, advancedtechnologies­ don’t always meet the markets
due to technical or cost issue. “For example
in Indonesia,­ the newly developed binarysystem­ rarely is suitable with. Most Indonesiangeothermal­ wells produce very high temperatures ­suitable only with conventional turbine.
“For example the Dieng (geothermal) wells
Alstom’s steam turbin
produce a very high temperature,”­ said McCartin. The British engineer who
has been working for various­
geothermal­ and electricalcompanies­ in Indonesia since1997 said that for Indonesia aconventional turbine system

Geothermal training at the Universityof Auckland ­—Juliet Newson
New Zealand is a beautiful country­
in the South Pacific that has
more than 25 high temperaturegeothermal­ systems, and many
warm water springs. The Wairakei
system in New Zealand was the first liquid­ dominated­high temperature geothermal­system­
to be used for power generation, and since then
New Zealanders have been at the forefront ofgeothermal research and training. More than700 students graduated from the University­ ofAuckland Geothermal Institute with a Diploma
in Geothermal Energy Technology between­1978and 2002, including more than 150 Indonesians;many­of whom are now leaders in the Indonesian­geothermal industry. Former students fromIndonesia,­ and all over the world, spent an
enjoyable­ evening catching up with old friends
at a University of Auckland Alumni function­ onTuesday­evening.
The University of Auckland now offers thePost Graduate Certificate in Geothermal Energy Technology (PGCertGeothermTech) andgeothermal­ research leading to ME, MSc or PhD
degrees in the Faculties of Engineering andScience.­­
The PGCertGeothermTech is a one-semester­
program aimed at giving engineering andscience­graduates training in geothermal scienceand engineering, available through the Facultyof Engineering at the University of Auckland. Thecourse is tought in Semester 2 (19th July – 12thNovember in 2010). Lecturers are from University­of Auckland and from the New Zealand geothermal industry.
The first five weeks of the course include
geothermal science and geothermal engineering. For the following five weeks there is a choice
between a geoscience elective or an engineering elective, with the last week of study spent
on a feasibility assessment. The aim is for thestudents­to work in groups of four to five people,
and apply everything they have learned to a realproject. In the last five weeks of the course all
students carry out a five-week industry-focusedresearch project.
Highlights of the PGCertGeothermTech
are the two six-day field trips to the Central

North Island of New Zealand. All students visit
geothermal­power stations and associated borefields,­­­ direct use projects, and undeveloped
geothermal­ systems with many natural geothermal springs.

WGC2010Bayu Pertiwi, a Dance of the Earth PowerFor Balinese, dance is a part oftheir daily routine. If you have
explored­ the island’s village life,
you will learn that children andteenagers­ practice dance routinely
in their village’s meeting halls, (bale banjar). blol
The WGC2010 cultural night, held at thefamous­ Garuda Wisnu Kencana (GWK) last night,feature one of the island’s vast arrays of dancecreation.­ Bayu Pertiwi (the force of nature) is adance specially created for the World Geothermal
Congress 2010.
According to the conceptor of the dance, as
well as script writer, Dr. Herman Darnel Ibrahim,
who is also the chairman of the OC WGC2010
he idea of the dance emerged from the need toportray geothermal as a clean energy capableof creating­ happiness and prosperity withoutchanging­ Bali’s strong culture. The process ofcreating­ this marvelous work of art took a longtime. “Since I got the idea to combine geothermal and the art of dance last year, there wereseveral meetings with the dance’s choreographerand composer, as well as lighting engineer. theresult­is a colossal dance involving more than 200dancers. I do hope that this work will get positive
appreciation,­” said Herman Darnel Ibrahim.
The dance is divided into four scenes, starting from the scene picturing an impoverishedsociety, followed by the breaking through scene
where the society finds geothermal steam beneficial and less pollutive, and ended by the happiness of the society who has lived in happiness andprosperity. This happiness is portrayed throughthe expression­ of spiritual gratitude on theirprosperity­and prolonged­culture.
The dance, choreographed by Dr.Ni Made
Ruastiti,­ a senior lecturer at the island’s most
famous­ dance institution,in Denpasar, highlights
the force of nature as the source of creation,
featuring­ hundreds of dancers representing thepowerful energy of the earth.
The words Bayu (force) and Pertiwi (earth)suggest that the dance represents the earth’s
energy­ which is turned into electrical power forthe brighter world for the human prosperity.

It is told that one day a powerful Hindu priest,
Ida Padanda Wawu Rauh, visited Bali and he wassaid to learn Bali in a dark atmosphere, no lighting­is available especially in remote villages. He thenthrust down his magical stick until the light cameout from the earth. The energy out from the earth
took the form of hundreds of dancers, led by abeautiful goddess known as Ni Dewi Njung Asti,symbolizing the energy as a good force for humanbeing.
The epic dance performance lasts for about 30
minutes.

Dedicated to Dance Creation

Ni Made Ruastiti

Ni Made Ruastiti, 45, the creator and choreographer of Bayu Pertiwi(the force of nature) dance, is one among the few Balinese choreographers who successfully develops a number of traditional Balinese
dances harmoniously combined with fusion and modern dances.
“The classic, indigenous Balinese dances are beautiful in themselves. However, such dances have been regularly featured in the many performances.­
For a special occasion like the geothermal conference, we should develop
and combine them with the related theme,” DR Ruastiti said.
The calm mother of two, who is going to hold a professor title by
the end of this year from the Bali’s Institute of Arts (ISI), has createdvarious dances related to various international issues such as global
warming,­ travel and tourism, environmental awareness, safety andprosperity, to mention a few.
