Message from the President
Roland N. Horne
With this letter to you, our members, I begin my threeyear term as IGA President. I hope to justify your trust inelecting me to this position, and I hope to emulate themany successes of my predecessors, especially the very
effective Ladsi Rybach with whom I have just changed
chairs. The International Geothermal Association is inrobust good health, the geothermal industry is expanding,and geothermal energy is finally beginning to gain some of
the attention it deserves among politicians, decisionmakers and the public. I’m looking forward to three yearsof continued growth of geothermal energy, and continued
growth of IGA. At the present time, IGA has more than
5000 members from 32 associations in 30 countries (withindividual members included, the membershipencompasses 65 countries). IGA is an association of
associations, and our function is to promote geothermalenergy by fostering education, information, and outreach.

These functions are also the common goal of many ofour member associations, and IGA can represent theworldwide geother mal community collectively, forexample by assisting with courses and conferences, and by
participating in larger worldwide renewable energy events.
During the past few years, IGA has joined the REN
Alliance, and has participated in renewable energ yconferences and congresses to make sure that geothermalenergy is not forgotten!
An important event that will occur very soon is thetransfer of the IGA Secretariat from Iceland to Germany.
We are very grateful to Iceland for having supported theSecretariat over the past years, and we are grateful to

October - December 2010

Germany for taking on the responsibility anew. We will
bid a fond farewell to our Icelandic Executive Director
Arni Ragnarsson, who nonetheless will remain active in
IGA as he has been elected a member of the new Board(he will be the chairman of the Membership Committee).
Then we will welcome a new Executive Director, who willtake up the position in Bochum, Germany in January 2011(or soon after). The German organizers are advertizing
now to fill this Executive Director position – if you areinterested in the post, please check the advertisement at
t h e I G A w e b s i t e ( h t t p : / / w w w. g e o t h e r m a l energy.org/files-259.html). Note that the Executive
Director will live in Bochum, Germany, but the position is
open to non-Germans.
As you may know, one of my special interests in IGA
has been the World Geothermal Congress. The 2010
Congress in Bali was a magnificent event, enjoyed by morethan 2000 people, with more than 1050 papers. The 20102013 IGA Board will be responsible to launch the
preparations for WGC2015 to be held in Australia and
New Zealand – in fact the preparations have alreadybegun. I hope to meet all of you there, and also hope thatyou’ll bring your colleagues and friends.
Another special interest of mine is education (because
my “other job” is as Professor of Energy Resources
Engineering at Stanford University in California, USA).
The new IGA Board has proposed the expansion of
support for educational events such as short courses to beheld at geothermal conferences, or independently. This isFig. 2: Incoming and outgoing Presidents Roland Horne (left) andLadsi Rybach

a concept that I support wholeheartedly. The more
people who know geothermal energy the better, and ourgeothermal community is short of qualified people as ourindustries expand and our more experienced professionals
retire. IGA can make a difference by fostering the
expansion of qualified personnel – greater in number, andstronger in expertise.
At our first Board meeting in Sacramento on October
29, the new IGA Board began to form the structures of
the committees that will undertake the many functions of
the association. Many of the committees include spaces
for IGA members who are not on the Board of Directors,
so if you have special interest in any of these functions, I
encourage you to contact the committee chairs and letthem know. IGA activities are completely accomplishedby volunteers (except for the Secretariat), so participation
by enthusiastic members is always welcome. The table on
the opposite page shows the current line-up of volunteers.

32 members of the old and new Board attended themeetings.
As usual, the IGA officers and the Chairmen of theeight permanent committees reported to the Board on theactivity since the last Board meeting. Also, the European
Regional Branch, the Western Pacific Regional Branch andthe ad hoc Reserves and Resources Committee reported to
the Board. Affiliation agreements with two new national
geother mal associations in Kenya and Chile wereapproved by the Board, increasing the number of affiliatedorganizations to 32. New committee chairs and committee
members were elected for the three-year term that has juststarted.

I GA New s No. 82

Participants in the Sacramento meetings
April 2010. There was general agreement that the congress
was an extremely successful event. The Board discussed
the preparations for the next world congress that will beheld in Melbourne, Australia in 2015 (WGC2015). An
MoU between IGA and an Australian/New Zealandconsortium (ANEGA) for organizing the congress was
signed at WGC2010 in Bali. A Steering Committee,
responsible for certain functions of the congress(technical programme, short courses, fellowships and fundraising) will be formed by IGA at the next Board meeting.
The term of the IGA Secretariat in Iceland will expire
at the end of 2010 when it will be transferred to Bochum,
Germany. It will be hosted by a consortium of four
partners, represented towards IGA through the GtV-BV. It
will be located at the Geothermal Center of the Bochum
University of Applied Sciences. The process of hiring a
new IGA Executive Director is ongoing.
In June 2009 IGA established a subsidiary, IGA
Service GmbH. It is registered in Germany and the sole
shareholder is IGA. An Advisory Group was set up to be
the Board´s contact towards the company. One of themain reasons for establishing the company was the planfor implementing an ARGeo project in Africa for theWorld Bank. Due to delays in the ARGeo programme theactivity of the company has so far been limited to small
projects together with other REN Alliance partners. The
Board decided that IGA Ser vice should apply formembership in EGEC (European Geothermal Energy
Council) and that could open the possibilities forparticipation in EU projects in the future.
IGA is a member of the REN Alliance (International
Renewable Energy Alliance) together with other worldorganizations within solar, wind, hydropower andbioenergy. The main activity so far has been participationin different renewable energy events and organization ofside events at climate change meetings. It also provides aforum for a joint representation of the RE sector towards
international organizations within the energy sector. The
IGA Board agreed on the importance of participating
actively in this cooperation.
A preliminary budget for 2011 was approved by the
IGA Board. Due to IGA´s share of the registration fee
and surplus of WGC2010 (approximately USD 130,000)
we are financially in a much better position than before.
Therefore, the Board agreed to increase the annual budget
to almost USD 60,000 from the present level of about
USD 40,000. More funds will be allocated for educational
events and possibly fellowships as well as other activities.

Among the decisions taken by the Board is to accept
paid commercial advertisements on the IGA website. Incase this will be implemented it will be taken care of by
the IGA Secretariat. The Education Committee raised theidea of creating some kind of young members’ activity
within IGA and also to form a new research activities
committee. This will be discussed further at the next
Board meeting.
At the Annual General Meeting of IGA (AGM 2010),
which was attended by about 30 members, brief reports
were given on the activity of the organization. The
President of IGA, Ladsi Rybach, handed over a letter of
thanks to Herman Darnel Ibrahim, Chairman of the
WGC2010 Organizing Committee and Surya Darma,
President of INAGA. In the letter IGA thanks andcongratulates the organizers of WGC2010 for theoutstanding success of the congress. Also, IGA gratefully
acknowledges the substantial transfer of funds to IGA
from the WGC2010 balance. Installation of new IGA
officers took place at the AGM. Roland Horne replaced
Ladsi Rybach as President, Colin Harvey replaced Ruggero
Bertani as Vice President, Horst Rüter replaced Gestur
Gíslason as Secretary and Herman Darnel Ibrahim
replaced Colin Harvey as Treasurer.
The next meeting of the IGA Board will be held at thesite of the new Secretariat in Bochum, Germany, 18-19

state of California, through October 24-27. The theme
was “Celebrating 50 years of clean, renewable energy”,
marking the fact that the first geothermal power plant in
the US started to operate in 1960, at The Geysers
geothermal field. Thus, it was appropriate that the IGA
BoD meeting finished by paying a visit to this field.
The field trip was kindly organized by EGS, Inc., aconsulting company based in Santa Rosa, and conductedby its President, Paul Brophy, who provided the transportand lunch, and made the proper arrangements. Paul was amember of the past IGA BoD, and is an experienced
geologist who spent several years working at The Geysers.
Twelve members of the new BoD, three of the past one
and some accompanying guests gathered at 8 am on
Saturday October 30, and headed to Middletown,
bordering the southern shores of Clear Lake. Middletownis the small village east of Sacramento where Calpine’s
Visitor Center is located.
Presently, The Geysers geothermal field is owned andoperated mostly by Calpine Corporation. The public utility
Northern California Power Agency (NCPA) operates thesoutheastern part of the field, as well as two power plants.
Calpine Corporation was founded in San José, CA, in 1984
and is a major US power company that operates 29,000
MW in 21 US states and Canada.
Once at the visitor center, the multinational IGA group(bringing together visitors from Germany, Iceland,
Indonesia, Japan, Mexico, New Zealand, Philippines,
Romania, and the US) was welcomed by two kind guides

who offered a wide and well-documented explanation
about the geothermal field, the power plants and thegeneral operation of the same. This opening explanation
was provided in the exhibition room of the center that
contains a model of the field and ingenious schemes
showing the basic operation of geothermal power plants.
The visitors were then provided with helmets, safety specs
and ear protectors, and went to the field located a few
kilometers northwest of Middletown.
The Geysers geothermal field is located in northern
California, in the Mayacamas Mountains 150 km north of
San Francisco, covering the north portion of Sonoma
County and some small portions of the neighboring Lake
County (to the east) and Mendocino County (to the north).
The currently known boundaries of the geothermal
reservoir comprise a northwest-southeast oriented, kidneyshaped area of roughly 115 km2 defined by two main faultsof the same direction: the Mercuryville Fault to the eastand the Collayomi Fault to the west. Inside this area is acomplex lithology that has been grouped in the following
units: Ultramafic, Franciscan Sediments and Melange,
M e so z o i c S e d i m e n t s, Fr a n c i sc a n Vo l c a n i c s, a n d
Quaternary Volcanics. The geothermal fluids, composedof dry or superheated steam at an average temperature of
218°C and an average pressure of 110 psig, are hosted by
the Franciscan formations whose rocks present goodprimary permeability.
The visitors were conducted to Calpine’s Unit No. 14,
named West Ford Flat. It is a 28 MW unit composed of
two turbo-generators commissioned in 1987. They
operated at an average capacity factor of 92% during 2009.
The unit was attended by one single operator who kindly
answered the several questions of the group, who thenmoved on to the Geysers Administrative Center. Here also
is the central control room where almost all the production
and injection wells and power plants are constantly
monitored and can be remotely operated.
Calpine owns and operates most of the field (around
100 km2 of the total) and 17 out of the 19 power units
currently in operation. The remaining two operating units
are NCPA 1 and NCPA 2, located in the southeastern field.
Calpine owns also another five power plants, currently
inactive. The total installed operating capacity of Calpine’s
17 power units is 725 MW, the first of which, Unit No. 1(named Aidlin after Joseph Aidlin, one of the pioneers of
the US geothermal development), started to operate in
September 1960. These plants produced 5949 GWh in2009 at an average annual capacity factor of 93.5%. This
electricity generation represents around 20% of all therenewable energy generated in California.
Calpine’s control room has two main terminals. One
monitors and controls all the power plants and the other
does the same with the steam-field. There are currently 345
production wells and 50 injection wells in operation, at an
average depth of 2590 meters (although the deepest well is3930 meters deep). The average steam production per well

October - December 2010

I GA New s No. 82
is approximately 17.3 tons per hour (t/h) or 4.8 kg/s, andthe total steam production of the part of the fieldmanaged by Calpine is around 5900 t/h (1640 kg/s).
Therefore, the average specific consumption of Calpine’s
power plants during 2009 was approximately 8.7 tons per
MWh, which implies a high efficiency. The Geysers being asteam-dominated reservoir, the production wells do not
produce liquid phase. However, some time ago it was
decided to start to inject water into the reservoir torecharge it, enhance the production and help to sustain thegeothermal resource. Currently the 50 injection wells are
injecting daily 11 million gallons (~1735 t/h or 482 kg/s)of treated municipal wastewater from Santa Rosa County,
located south of the field, and 5.2 million gallons per day(~818 t/h or 227 kg/s) from the neighboring Lake County.
Thus, the total injected volume of water (2550 t/h)
represents more than 40% of the extracted volume ofsteam.
The municipal wastewater is conducted to the injection
wells by 105 km of water pipelines. Water from Santa Rosa
is concentrated into a high-elevation tank located in thesouthern field and then is injected by gravity. The
produced steam is conducted to the power units throughapproximately 129 km of steam pipelines. All of thesesurface installations are real-time monitored and can beremotely operated from the control room, where also aremonitored and controlled approximately 95% of thealmost 400 operating wells (production plus injection).
Although the wells present very steady conditions overtime (some currently operating wells were drilled morethan 30 years ago), and therefore no make-up wells are
required, Calpine has drilled a total of 575 wells in the field.
Presently, the average cost of a 2600 m-depth well is
US$x6.5 million and it is completed in 85 days (75 days
drilling plus 10 days for erection and removal of the rig).
Most of these wells are directional, using a single pad todrill up to five wells.
After lunch and the visit to the control room, the IGA
visitors were conducted to the Sulphur Springs thermalarea and then to the Geysers Rock. The slightly rainy
weather of the afternoon allowed only a quick stop at thearea of surface manifestations. The group then returned to
the Visitor Center in Middletown to finish the field triparound 4 pm.
On the way back to Sacramento, the bus headed to thesouth of Middletown in order to pass through the famous
Napa Valley where most of the finest Californian wines areproduced. No stop had been scheduled, but the IGA
visitors, led by its New Zealand section, got the proper
authorization to make a quick stop in one of the vineyards
in the valley and taste one or two Californian wine samples.
That was a perfect end for a very interesting trip, andultimately for a busy week that comprised the GRC annual
meeting and the IGA BoD meetings.

MexicoThe Mexican Geothermal
Association held its XVIII
congress and assembly
Luis C.A. Gutiérrez-Negrín, MGA Vice
President
On October 15, 2010, the Mexican Geother mal
Association (AGM: Asociación Geotérmica Mexicana)carried out its XVIII annual congress and assembly at theheadquarters of the geothermal division of the Federal
Commission for Electricity (CFE: Comisión Federal deElectricidad) located in Morelia, Mexico.
The AGM was founded in 1992, and since then hasorganized one congress and assembly yearly with some
additional extraordinary assemblies. It is currently anaffiliated organization with the IGA, whose affiliationagreement extends up to 2012. Its eighteenth meeting
gathered around 40 participants from the CFE, theE l e c t r i c a l Re s e a r c h I n s t i t u t e ( I I E : I n s t i t u t o d eInvestig aciones Eléctricas), and the National andMichoacán universities. Most participants were researchersand engineers who have long been involved in geothermal,
including some now retired from the CFE, but there werealso a significant number of young CFE employees, among
them one of the speakers.
Ten technical papers were presented, covering subjects
such as the national assessment of low- and intermediatetemperature geothermal resources in Mexico; the results ofsampling and analyses of radon in soils of the Las Tres
Vírgenes geother mal field; a new code called
GeoSteamNet for simulating steam flow in steam

GIS to compile the actual conditions of the thermal
insulation on the Cerro Prieto field pipelines; thedetermination of heat losses in those pipelines, due tofailures in their insulation, and in the accessory valves andother devices; some experimental results on changes inreservoir rocks of the Los Humeros field after acidtreatment; the general effects of injection in the southernLos Azufres field according to results of tracer studies; andsome practical models for geothermal reservoirs.

After the lunch, those members of the AGM attending
the congress started the annual assembly under thepreviously distributed agenda. The AGM President for
2009-2010, Raúl Maya-González, who is currently in chargeof the CFE’s geothermal division, called to order and readthe minutes of the last assembly in 2009, which wereapproved. The Secretary, Luis Gutiérrez-Negrín, presented
the Board of Directors’ report for the last year, and theTreasurer, José Luis Quijano, presented his yearly report.
Both were also approved.
Raúl Maya-González then presented the 2010 Pathéaward. This award was instituted by the AGM in 2005 torecognize the career and activities of relevant persons
involved in geothermal in Mexico during at least 15 years.
The 2010 Pathé award went to Ramón Reyes-Suárez, who
graduated as a chemical engineer from the National
Polytechnic Institute in 1959. In 1976 he joined the then
CFE’s Geothermal Department where he was in charge ofthe exploratory and development drilling in all thegeothermal fields and zones of the Mexican Volcanic Belt
(central Mexico), based in the Los Azufres geothermal field.
In 1982, when the CFE’s geothermal division was formallyfounded, he was appointed as general manager of the Los
Azufres field, where he was in charge of the installation of
the first back-pressure power units, some of them being
still in operation. In 1989 he was appointed as head of theDrilling Department based in Morelia, being responsible
for all the drilling programs of geothermal wells in Mexico.
He left CFE in 1991 and started to work as Technical
Director for the Mexican drilling company Latina, having as
his main duty all the geothermal drilling operations of thiscompany in Mexico (especially in the Cerro Prieto
geothermal field) and Latin America up to 1996. Since thenhe has been an independent consultant for several privatecompanies and regional institutions, such as the Latin
American Organization for Energy (OLADE) and theInter-American Development Bank (IDB). The Pathéaward was delivered to Ramón Reyes-Suárez, in a simple
but emotive ceremony, by Alfredo Mañón-Mercado who
was the recipient of the 2009 Pathé award.
The new board of directors for the period 2011-2012
was then elected. According to its by-laws, the new
President of the AGM is the Vice-president of theprevious board, and therefore this post is not subject toelection. All the remaining posts have to be elected. Ballot
papers had been sent previously to the membership, andothers were completed during the assembly. Two members
volunteered to scrutinize and count the valid votes, and the
new board is as follows:
President: Magaly Flores-Armenta (from CFE and former
2009-2010 Vice-president)
Vice-president: Luis C.A. Gutiérrez-Negrín (consultant)
Secretary: Alfredo Mañón-Mercado (Geocónsul)
Treasurer: José Luis Quijano-León (consultant)Pro-secretary: Georgina Izquierdo-Montalvo (IIE)
Pro-treasurer: José Manuel Romo-Jones (CICESE)

Magaly Flores-Armenta addressed the assembly andpresented the general goals of her two-year tenure. The
assembly finished by discussing some old and new businessand taking the traditional photo in the recent offices of the
CFE’s geothermal division.

Tsvi Meidav (1930-2010)
William Teplow, U.S. Geothermal
Tsvi Meidav was a visionary and pioneering force forcommercial geothermal development in the United States
and worldwide. He passed away on September 29, 2010.
Born in Poland in 1930, he emigrated to Palestine withhis family in 1934. As a youth of 17 he fought in the Israel
War of Independence. After the war, he attended college
in the US, starting at San Mateo City College and received
his Ph.D in geophysics from Washington University, St.
Louis, Missouri.
After working for the United Nations geothermal
program, developing geothermal resources in Asia andAfrica, he founded his own geophysical consulting firm,
Geonomics. Geonomics performed exploration workthroughout the Western US and abroad. Many of thedetailed datasets generated by Geonomics during the ’70s
are still useful today in the exploration and development ofgeothermal fields throughout the West. Several key
leaders of the geothermal industry today got their start at
Geonomics.

I GA New s No. 82
In 1980 Tsvi formed Trans-Pacific Geothermal Inc.
(TGI), a commercial geothermal development company,
with the backing of private investors. TGI acquired
230,000 acres of federal and private geothermal leases
throughout the Western US and initiated an aggressive
exploration program. TGI success in drilling two of thehottest wells ever drilled in Nevada was key to thedevelopment of the Dixie Valley 50 MW geothermal
project. After being rebuffed by the local Nevada utility
Sierra Pacific Power for a power purchase agreement for
the Dixie Valley resource, Tsvi forged ahead with therouting and permitting of a 230 mile private power line, atthe time the longest in the US, to deliver the power toSouthern California Edison at Bishop, California. Thisfacilitated the sale of Dixie Valley power under a lucrative
40 MW Standard Offer Number 4. Oxbow Geothermal,
purchaser of the project from TGI, constructed the Dixie
Valley power plant and power line which went into service
in 1987.
After the sale of Dixie Valley, Tsvi’s newly constituted
company, Trans-Pacific Geothermal Corporation, TGC,
continued geothermal development throughout theWestern US and in Central America. His efforts resulted
in successful completion of the Stillwater, NV andAmedee, CA geothermal power projects.
In 1996 Tsvi acquired a large geothermal concession in
Nicaragua and executed an extensive g eophysicalexploration program. This program identified several highquality commercial geothermal prospects within theconcession. A similar effort in Honduras entailed theacquisition and exploration of the Platanares geothermal
resource.
Tsvi is survived by his wife, Dr. Mae Ziglin Meidav,
their children, Tamar of California, Professor Edie Meidav
of New York, and Dr. Josh Meidav of Washington, andgrandchildren, Eliana, Shira and Dalia.

Netherlands, this time in the city of The Hague.
Denmark: Sonderborg Geothermal dig breaks ground!
Sonderborg Fjernvarme and DONG Energy are drillingon this new geothermal site. It will host the geothermal
well and facility that will supply a large portion ofSonderborg’s heating in the future from a climate-friendly
source. It will not be long now! Sonderborg will soon
become the third place in Denmark where clean, CO2neutral heat will be literally pumped right out of theground. If all goes according to plan the facility will supply
Sonderborg city with a third of its annual consumption of
district heating by the year 2012. The Project is an

Plans to build the UK’s first geothermal energy plant
have been given the go-ahead. Members of Cornwall
C o u n t y C o u n c i l ’s s t r a t e g i c p l a n n i n g c o m m i t t e eunanimously voted in favour of Geothermal Engineering
Ltd’s plan. Work is now expected to begin on the United
Downs Industrial Park near Redruth, West Cornwall.
The plant is being developed by London-based
Geothermal Engineering and is intended to generate
55MW of renewable heat energy and 10MW of electricity
when it becomes fully operational in 2013. Approval of theplanning application last week (August 13) means thecompany can drill three wells 4.5km in depth at the United
Downs industrial estate, which is an existing brown fieldsite. Work is set to start in early 2011.
Ry a n L aw, m a n a g i n g d i r e c t o r o f G e o t h e r m a lEngineering Ltd, said: “With the development of our plantwe want to make deep geothermal energy a significant
contributor to the UK’s energy portfolio. Not only can wecontribute renewable, continuous power to the grid, we
also want to change the way the UK meets its heat
demands by offering energy-efficient, decentralised heat.
The Department of Energy and Climate Change has
already estimated that deep geothermal technology could
supply between one and five GW of baseload, renewableelectricity by 2030.”

EGS in ‘ground-breaking’ deep
drilling tie-up
The following is based on a report published by Newsco Insider
Ltd on 3 November 2010:
Cornish geothermal energy firm EGS Energy, which iscurrently awaiting planning permission to build a £25m
geothermal scheme at the Eden Project near St Austell,
Cornwall, England, has partnered up with a Slovakian
company to develop a ground-breaking new form of deep
drilling technology that it hopes to use on its geothermal
projects in the South West of England. EGS Energy,
which is based in Penzance, has teamed up with
Geothermal Anywhere to work together on applications
for European grants in the coming months.
Bratislava-based Geothermal Anywhere is developing a
new deep drilling technology for the geothermal sectors
based on non-contact methods of rock disintegration. Oneof the main issues for the deep geothermal industry is thecost of drilling to the required depths as a result of thetime that this takes, but EGS said that Geothermal
Anywhere’s drilling method avoids the inherent limitationsof conventional rotary drilling.
EGS Energy said: “This deep drilling approach is arock crushing technology based on bringing together anelectrical discharge, pulsed plasma and a jet of water inappropriate combination.” Roy Baria, technical director of
EGS Energy, said: “We are excited to have the opportunity
to work with Geothermal Anywhere on a project that
could improve significantly the commercial returns in thenascent deep geothermal sector.
“Our experience of deep drilling for geothermal targets
is extensive and we believe that we can add substantially towhat is already an excellent team and a ground-breaking
technology.”
Igor Kocis, CEO of Geothermal Anywhere, said:“Geothermal Anywhere is now entering a new stage of thecompany development. We have the essential financial
coverage of our R&D costs for the creation of a drilling
prototype. We now need international partnerships andcommon projects with experienced companies from thedrilling and engineered geothermal system fields. EGS
Energy is such a partner and we expect mutual benefits
from this alliance.”

South Australia, from 17–19 November. A number ofassociated short courses are scheduled for Tuesday 16
November. Approximately 300 people are expected toattend the Conference, attracting participants from allparts of the geothermal industry across the country, and anumber of international visitors.
Day 1 of the Conference is entirely in plenary format
and is devoted to ‘big picture’ talks about where theAustralian geothermal industry currently sits and where itis heading. The afternoon will provide up-to-date
information on projects from a number of development
companies - Geodynamics Ltd, Petratherm Ltd, Panax
Geothermal Ltd, KUTh Energy Ltd, New World Energy
Ltd, Torrens Energ y Ltd, Granite Power Ltd andGreenearth Energy Ltd.
Day 2 of the Conference begins with an update on theInternational Partnership for Geothermal Technology, acollaborative effort between Australia, Iceland and UnitedStates to tackle R&D issues surrounding unconventional
geothermal resources, and some of the specific challenges
Australian groups are working on. The Conference thensplits into three parallel streams of technical talks for the
next day and half.
Day 3 wraps up with an up-to-date account ofreservoir stimulation in Jolokia 1 by Geodynamics Ltd; andan update on climate change science and the view of theIntergovernmental Panel on Climate Change by Professor
David Karoly, just to remind us of why we are all doing
what we are doing.

Derek Harry Freeston (19292010)
Patrick R. Browne, University of
Auckland
Derek Freeston died peacefully at home with his family
nearby on October 9, 2010. He had been unwell for sometime but his loss still came as a shock to his colleagues,
former students and many friends.
Derek was a major contributor to the geothermal
communities, both national and international, in multiple
ways, including academic (both research and teaching),
commercial and administrative. He combined thesecomponents effectively to the benefit of all three.
Derek grew up in Leicester, England and never quite
lost his accent. He graduated from the University of
London and was an engineering officer in the Royal Air
Force based at Hendon. After leaving the RAF, Derek
helped design the air intakes for jet aircraft, including theConcorde Airliner. Derek long maintained his interest in
aircraft design and the history of the RAF.
Derek and his young family migrated to New Zealandin 1969 when he took up an appointment in the
Department of Mechanical Engineering at the Universityof Auckland where he established a wind tunnel. This was

October - December 2010u s e d f o r a w i d e va r i e t y o f p u r p o s e s, i n c l u d i n g
understanding wind flow patterns in down town Auckland.
In this period he also designed the condenser pots
subsequently widely used in several steam fields. However,Derek also became interested in two-phase flow and wasseconded to the staff of the newly established Geothermal
Institute in 1978. He was the sole engineer and responsible
for organizing and teaching the engineering component of
the new courses as well as guiding masters and doctoral
students in their research. He was able to continue his own
research, which he did through his students and bycooperating with engineers directly involved with steam
production.
Although the results of his research were importantand have practical benefit for the geothermal community,
Derek became better known for his teaching andmentoring of students. He taught several hundred during
his time at the Geothermal Institute but retired from the
University in 1992.He then held an honorary position,
giving lectures and advice to students and staff for many
years. Derek also took the opportunity to teach courses inother countries that were then establishing their own
geothermal programmes. He visited Indonesia on several
occasions where he both taught and learnt. His legacy
persists there and no doubt in other countries where hespent time, including Kenya, Iceland (UNU), Philippines,
China(Geothermal Department,Tianjing University), El
Salvador, Mexico and USA (Geo-Heat Center, Oregon
Institute of Technology).

Derek took for granted that students wanted to learn
and in almost all instances his expectation was realized. It
was a personal disappointment for him if a student did nottry 100%. If a student was having trouble but wanted tolearn, however, then Derek would spend hours helping
her/him. He was, in fact, an ideal teacher both in theclassroom and the field but also because he really caredabout students, recognizing that many were a long way
from home, living in a hostel with other, mostly younger,
students who had a different culture and language.
Students and staff always enjoyed visiting him and his wife,
Yvonne, for a barbecue at their home on the beach east of
Auckland city.
Derek liked to be in the field and over the years
developed an interest in geology. On joint field trips withengineers and earth scientists he was often more attentive
at an outcrop than were some of the geology students.
Derek contributed to the national and international
geothermal communities. He was instrumental in founding
the New Zealand Geothermal Association and served on
its Board for several years. He was also active within theInternational Geothermal Association as a Board Member
and, with John Lund, wrote country updates for the World
Geothermal Congress meetings. With John and Toni Boyd
he even wrote the countr y update for WGC2010,
testimony to his continued interest in geother mal
technology. Derek was on the Peer Review Panels for the
Rotokawa and Ngawha Geothermal Fields and received
both life membership of the NZGA and a Special Award
from the Geothermal Resources Council.
Derek had many interests outside geothermal, mostnotably his family. He had a yacht for many years and very
reluctantly gave up sailing a couple of years ago. Derek
was devoted to his church where he was a bell ringer andfollowed rugby and other sports intently.
Derek was a good friend to many who will have fondmemories of his cheerful presence and wise counsel. We
extend our deep sympathy to Yvonne, his son Mark andhis daughters, Marion and Janet and their families.
