In Mumbai,

I stayed at a guesthouse on the Indian Institute of Technology (IIT) campus by Powai Lake. Since my flight landed at 3:20am, the management was asleep when I arrived at the guesthouse and so I decided to wander around campus for a few hours. Since the campus lies in a heavily forested area, the wildlife on campus is quite diverse. Over the couse of my time at IIT, I saw crabs, monkeys, cattle, dogs, lizards, swans and all manner of other types of birds. Here's a short video I took at sunrise on Lake Powai on the morning of my arrival and a few pictures of some of the creatures that I saw during my stay at IIT.

My visit to IIT Bombay was prompted by my desire to talk with Professor Chetan Solanki about his work in the area of silicon solar cells and about the many projects going on at IIT in the broader area of solar energy technology. As part of the Indian National Solar Mission, the National Center for Photovoltaic Research and Education has been established at IIT Bombay for the purpose of assisting in achieving the national goal of 20 GW of installed solar energy systems by 2020. Towards this end, research across the full spectrum of solar energy technology is being pursued at the center. Additionally, courses are offered to current university students as well as to professionals of all levels of expertise and certification programs for technical workers are being developed. As part of this large research endeavor, the IIT Bombay Department of Energy Science and Engineering is collaborating with government and industry partners to build at 1 MW solar thermal power plant in Delhi which will serve as a technology evaluation and testing ground.

On the first of my sight-seeing days in Mumbai, I visited Sanjay Gandhi National Park. The park is located north of downtown Mumbai and lies between the eastern and the western city suburbs. With an area of 104 square kilometers, it holds the world record for the largest park within a city boundary. In the park, I took a seven kilometer motorbike ride into the forest in order to see the Kanheri Caves. The Kanheri Caves are Buddhist dwellings and religious spaces which were carved into basaltic mountain rock between the 1st century BCE and the 10th century CE. The caves feature carvings of Buddha and other religious figures, ancient inscriptions and stupas, mound-like structures which often contain Buddhist relics. Below are a few photos and a video that I took while exploring some of the 109 caves.

After exploring the caves, I visited the park's information center. The center contains a number of displays about local flora and fauna, as well as about climate change and the importance of the conservation of resources and wildlife habitat. A short hike from the information center is a memorial to Mahatma Gandhi which features a central pavilion and surrounding gardens as can be seen below.

The following day, I took a tour of Mumbai in order to explore the jungle of the innercity. During my tour, I visited a temple of the International Society for Krishna Consciousness, a beach upon which a large ship had been forced to make an emergency landing, a public laundry, the Hanging Gardens of Mumbai which feature a variety of animal-shaped carved hedges, Gandhi's residence, Victoria Station and the Gate of India. Below are some pictures from my urban adventures.

After the completion of my time in Mumbai, I flew to Ahmedabad, a city in the northern state of Gujarat, in order to visit Dr. Omkar Jani at Pandit Deendayal Petroleum University (PDPU) and the Gujarat Energy Research and Management Institute (GERMI). While both institutions were established through the Gujarat State Petroleum Corporation, their work does not focus exclusively on oil and natural gas. In fact, GERMI has an entire solar research wing which works in solar energy policy, technology and education. Seeing as Gujarat is the most progressive Indian state in its pursuit of renewable energy usage and established substantial state solar energy goals and subsidy programs before the national government did, GERMI is in prime position to have a very significant impact. Currently, GERMI is partaking in a number of exciting projects including a 1 MW photovoltaic test facility on the campus of PDPU and a city-wide rooftop installation program.

Staying in the university dormitories at PDPU, I had the opportunity to meet some of the students who had remained on campus for the summer in order to do internships with the Gujarat State Petroleum Corporation. It was fascinating to chat with my new friends, Larsika and Swastika, about their work and about the differences between American and Indian culture while exploring the areas surrounding campus.

Following the conclusion of my visit to Ahmedabad, I flew back to Mumbai and prepared to depart for Dhaka, Bangladesh.

Following my time in Munich at Intersolar Europe,

I took the train back to Berlin and prepared to depart for Doha, Qatar.

I knew that with this next flight, I would be departing from familiar territory. While western Europe is most assuredly very different than the United States, I anticipated that it would be much more similar to what I was familiar with than Qatar, India and Bangladesh would be. 

My instincts did not prove me wrong. My time in Doha, Qatar was a fascinatingly foreign experience. Stepping off the plane and into customs, I was surrounded by people dressed very differently than me. While in the United States, I blend into the crowd with my t-shit and jeans, here I stood out like a sore thumb amongst the many men in thawbs and women in burqas. After passing through customs, I walked outside to see if I would be able to find a taxi to take me to the hostel I had booked for myself. It was almost midnight and I was ready to have a place to sleep.

After waiting for twenty minutes in the lengthy line of people queued for taxis, it was finally my turn to get into a cab. The cab pulled up. I placed my trumpet and my backpack in the trunk and slid into the passenger seat. "I would like to go to the Doha Youth Hostel at 17 Al Rayhan Street," I said. The cab driver responded with a quizzical look and broken English that was difficult for me to understand. Hmmm, no GPS, I noticed as I looked around the dashboard of the car. Perhaps the map with the hostel location marked that I've saved for just such an occasion will be of use, I thought. I pulled out my phone and displayed the map with the location that I desired to go to clearly marked. The cab driver appeared puzzled. After a few more attempts to communicate my desired destination, I stepped out of the cab. The cab driver had indicated that he was interested in taking a different customer, someone who was looking to travel to a destination with which he was more familiar. Perhaps another taxi driver would have a better knowledge of where I wanted to go, he said.

Ok. Sure, I thought. Maybe someone else will have a better knowledge of where I want to go.

Unfortunately, that was not the case.

This scene repeated itself two more times before the airport official in charge of directing people at the front of the taxi line to their car became tired of having to refill my cab and redirect me to another vehicle. Stepping in to assist, he assured my third driver that the Doha Youth Hostel was behind the American Embassy, a landmark with which my driver seemed familiar. Excellent, I thought. 

We were off.

That's funny, I noted, looking at the map on my phone as we drove away from the airport. It doesn't have the American Embassy marked on here. A strange omission. Perhaps security concerns...

Sure enough, upon our arrival to the neighborhood behind the American Embassy, there was no youth hostel. 

After making a few phone calls and stopping to ask the locals for advice, my driver continued on. Apparently, two years ago, the hostel changed locations, he explained to me. 

What? Two years ago!?! Had nobody gone there from the airport since then?

Another ten minutes of driving down dusty, poorly lit streets and we arrived in front the new location of The Doha Youth Hostel where the seven foot tall entry gates had been securely locked for the night. Having brought me this far, my driver was not deterred. He incessantly rang the door bell until the manager of the hostel was raised from bed and came to open the gate.

I had finally arrived! They had a room for me and I could finally sleep! I thanked my driver profusely and went immediately to bed.

Checking back in the morning, my faith in myself and in technology was affirmed. The hostel was exactly where I had stated it would be and where Google Maps had shown it to be: 17 Al Rayhan Street.

That same morning, after another troubling transportation experience in which I waited approximately two hours for a bus which never arrived, I hailed a cab to try my luck again in an attempt to get to the Museum of Islamic Art at the Doha port. This time, I found much more success and after a pleasant drive through the city during which my driver pointed out a number of interesting local landmarks, I arrived at my destination.

The museum was beautiful. It was designed by famed architect I. M. Pei and was stunning to behold. The collections which it housed where equally amazing and I very much enjoyed my chance to learn more about Islamic arts and culture by visiting there.

Below are a few pictures and videos highlighting the museum and its collection:

(I want one.)

The following day, I visited Mike Farshchi at the Chevron Center for Sustainable Energy Efficiency (CSEE) at the Qatar Science and Technology Park. The goal of the Chevron CSEE is to educate the decision makers of Qatar about energy efficient building practices and to evaluate the performance solar energy systems in the gulf climate. Currently at the offices of the Chevron CSEE is an engaging interactive display explaining different lighting options and building temperature control schemes. The main purpose of the display is to communicate that by making energy efficient choices in the construction of buildings and public structures, the nation of Qatar will need to produce significantly less electricity and thus will have a greater amount of natural gas to export. Currently in the early stages of construction outside of the Chevron CSEE offices is the test ground for solar energy systems. Mr. Farshchi anticipated that by mid-2012 the test ground would be up and running, and a number of installed photovoltaic systems would be being actively evaluated for performance in the local hot, humid,  windy and dusty climate.

After three nights in Doha, it was time for me to leave Qatar for Mumbai, India. I packed my things, checked out of the hostel and marveled at the fact that during the four days that I had been at the hostel, I had not seen a single other traveler.

Had I been the only person staying there?

In Berlin,

I met up with Gustav by the Brandenburg Gate, a prominent Berlin landmark built in the late 18th century which was the site of Ronald Reagan's famed Cold War speech in which he demanded "Mr. Gorbachev, tear down this wall!"

Following our introduction, Gustav proceeded to give a fact-filled tour of the surrounding area's major landmarks as we walked by the Reichstag building (home of the German parliament) and the Bundeskanzleramt (home of the German chancellery), 

across the line where the Berlin wall had once stood and down Unter den Linden, a street where many building from the Prussian period still stand. Neue Wache, that is "New Guard House", a Prussian guardhouse from 1816, which is now the "Central Memorial of the Federal Republic of Germany for the Victims of War and Tyranny", was a particularly moving site.

Following a traditional Bavarian lunch of weisswurt, ein brezel und weissbier, and a visit to the Akademie der Kunste, the official arts council to the German government (of which Gustav is one of five hundred members chosen from throughout the German arts world), we retired to Gustav's apartment to chat about his work as a newspaper editor, journalist and author of historical books.

The following day, thanks to the much-appreciated assistance of Mr. Tymen DeJohn, First Solar's vice president of global manufacturing, I visited the offices of First Solar in Berlin and their manufacturing plant in Frankfurt an der Oder, a city east of Berlin, near the German-Polish border. First Solar is a global leader in the manufacturing of thin film photovoltaics and it was a fantastic learning experience to visit them. In Berlin, I received a presentation from Max Junghanns which gave a broad overview of the company, and in Frankfurt, I received a tour from Mr. Burghard von Westerholt of the manufacturing facilities where 9,000 photovoltaics panels are made each day on lines that operate 24 hours a day, 365 days a year. The scale, precision and rapid growth of their operation was truly stunning.

At both the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg and the offices of First Solar in Berlin, I had been informed that it might interest me to adjust my travel plans in Germany in order to attend Intersolar Europe, the largest solar energy industry exposition in the world, in Munich from June 6 to June 10. I gladly accepted this advice and purchased a train ticket for myself in order to travel to Munich. While conference tickets were of the order of €1000, the Fraunhofer Institute, as an organizing partner, was kind enough to help me get into the conference free of cost.

At the conference, I attended a number of informative talks given by industry representatives, market analysts, national politicians and academics. The presentations which I attended were on a wide variety of topics including "India's PV Market Development", "Balance of Systems" (an analysis of the power electronic devices used in connecting photovoltaic power plants to the grid), "Concentrating PV" and "PV Energy World" (a presentation by representatives of Fraunhofer ISE and Siemens on the progress made by and the future prospects of renewable energy technologies). In addition to conference talks, I attended the industry exposition and strolled through hall after hall of industry exhibitors, marveling at the number of players in the market and listening to sales pitch after sales pitch.

On June 1,

I arrived in Moselkern, a tiny village on the edge of the Mosel river. The purpose of my visit to this quaint setting was to visit Burg Eltz, a 12th century castle about an hour's hike through the woods surrounding the town. And so, once again I wandered through a beautiful German forest in search of a castle taking photos along the way.

Success!

Having achieved what I had set out to do in Moselkern, it was time to move on. 

My next destination was Bad Neustadt, a city near the northern border of the German state of Bavaria. In coming to this area, it was my intention to visit the lands of my ancestors.

My grandmother, Sarah Limpert, has done extensive research into my family's history and one of her greatest findings is a ship's log documenting the immigration of Bernhard Limpert and his wife, Dorothea Schublein, to the United States in the mid-19th century from Nickersfelden and Brendlorenzen, Germany, respectively. On today's map, one will find that the once independent village of Brendlorenzen has become a district within the larger city of Bad Neustadt, but that the village of Nickersfelden remains very much as it may have been over a hundred years ago, a small rural farming village of only a few hundred inhabitants. 

Renting a bike, I set out from Bad Neustadt towards Nickersfelden and the other surrounding villages in search of churches and graveyards were hints of my family history might be hiding. Upon my arrival in Nickersfelden, I recorded a short video while walking into town and had a picture taken of me at the city sign.

While my search of churches and graveyards did not turn up any 19th century familial connections, I did find this:

a small church and graveyard high atop a wooded foothill honoring local soldiers who lost their lives during the battles of World War II. Walking through the rows of grave markers, I found out that, while my grandparents had made it through the war unscathed, perhaps not everyone in my larger family circle had been so lucky.

From Bad Neustadt, I set off for Berlin, where I was to visit both my father's old friend, Gustav Seibt, a leading German historian, journalist and literary critic, and the offices of First Solar, a world leader in thin film photovoltaics manufacturing.

My first day in Freiburg, Germany,

I decided to take a walk through the Black Forest. I had been told that deep in the woods, there was an observation tower from which one could look down upon the entire city. I set off in search of the tower and as I walked, I recorded these images.

Success! I found the tower!

Now, to climb the tower:

And record the view from the top:

With that video taken, I climbed down the tower and wended my way through the woods back toward civilization as the sun set and the forest dimmed.

Having spent my first day in Freiburg exploring nature, I wanted to spend my second day exploring the city. I was particularly interested in visiting the Vauban Quartier, a portion of the city home to an innovative sustainability focused community. The most notable buildings in the quarter are the fifty-nine PlusEnergy homes designed by the German architect Rolf Disch. These homes have a positive net energy balance due to their low energy consumption and solar energy utilization. In fact, not only are these houses ecologically beneficial, but they are economically beneficial. The homes' owners are paid by the utility company for every kWh of electricity that is produced by their solar panels and put onto the electricity grid for use by others.

The day following my exploration of the Vauban Quartier, I walked across the city to visit the Fraunhofer Institute for Solar Energy Systems. I began my visit by meeting with Mr. Gerhard Stryi-Hipp, the director of energy policy. Mr. Stryi-Hipp gave me a presentation regarding the institute’s structure and its many areas of endeavor, and then discussed Germany’s solar energy technology subsidy programs. Following this, I received a tour of the institute’s solar thermal system test facilities from Mr. Stefan Fortuin.

Everyone at the institute was quite excited at the news of the previous day: Germany would be phasing out the use of nuclear power and shutting down all of its nuclear power plants by 2022. At lunch, this was the talk of the table. Mr. Stryi-Hipp, Mr. Fortuin, Mr. Gerhard Willeke, Coordinator of PV, and Mr. Stephan Schindele, a master’s student working on a comparison of the energy policies of California and Germany, all commented on how they could not believe that it had actually happened. In a shocking move, the conservative government had altered its stance on the issue and made its decision on the matter in the wake of the Fukushima disaster.

Finally, all of these posters that I had seen throughout the city could be taken down.

The decision to shut down Germany’s nuclear power plants was yet another in a series of policy decisions which have made and will continue to make Germany a world leader in the use of renewable energy in general and in solar energy specifically. Everyone at the institute was, understandably, very pleased about this.

Following lunch, Mr. Schindele gave me a presentation regarding his masters thesis, "Photovoltaic dissemination regulations in California and Germany: Why the German PV market developed remarkably faster than the one in California". It was a fascinating analysis of the effects of different incentive programs on the development of renewable energy technology markets. According to Mr. Schindele, renewable energy portfolio standards, as implemented in most US states, will tend to grow the market for the cheapest renewable energy sources and will have little effect on the market for more expensive renewable energy sources. In contrast, feed-in tariffs, as implemented in Germany, if structured properly, can be used to grow the markets for renewable energy resources across the full cost spectrum. One of the results of the US renewable energy portfolio standards has been a tremendous growth in the wind energy market. However, the US has experienced very little growth in the photovoltaic market. As a result of its feed-in tariffs, Germany has successfully become a global leader in the development and use of solar energy technology and has brought down its cost significantly in the process, while simultaneously making great strides in the use of wind power.

My final meeting of the day was with Dr. Eicke Weber, the director of the Fraunhofer Institute for Solar Energy Systems. Dr. Weber emphasized the urgency of the work being done on renewable energy technologies at Fraunhofer ISE and around the world. According to Dr. Weber, the development and application of these technologies is key to humanity's continued success on this planet. As our conversation came to a close, Dr. Weber expressed his hope that the US would begin to play a greater leadership role in the use of renewable energy technologies and in dealing with the real global problems of the 21st century.

After a brief tour of a laboratory investigating systems for intelligent automated management of residential electrical generation and load supply, my visit to the Fraunhofer Institute for Solar Energy Systems came to a close and I returned to the hostel to pack for my departure from Freiburg the next day.
