Thoughts on a Sunny Disposition

I thought I would take a crack at “lightening” everyone’s mood a little bit by reflecting on the long road behind us, rather than the short stressful one ahead.

It seems rather amazing to me that over a year ago we first heard the words ’solar’ and ‘decathlon’ used in the same phrase. At this point I almost do not remember a time when The Solar Decathlon was not my entire life, but maybe that is a good thing.

The project started in early June, 2006 with a few emails and informal meetings. Those of us that had not secured an internship going into the summer of ‘06 decided that working on a ‘little’ school project might be fun. Reflecting back it is amazing to me how little progress we made initially. True we spent lots of time researching, and lots of time learning, but given our current rate of progress the stuff we did last year was child’s play. Of the people that worked that summer only about 4 of us remain on the project . I think any one of us would tell you that the sense of urgency and the magnitude of what we were setting out on had definitely not settled in. Last summer was a lot of fund raising, networking, appliance selecting, material research, planning, and architectural structuring. The sad part is that none of those ‘finalized’ plans ended up being anywhere close to our final product. I still see pictures of our original house-plan floating around on the internet. I can’t help but chuckle when I see the long rectangular box dreampt up in that first summer.

Summer Team 06

The Summer Team ‘06

Throughout the school year the team struggled to find its center. We had people come and go, great ideas, bad ideas, ideas in between. Looking back, I feel like we were all over the place, and yet one thing remained constant: we started becoming a cohesive team. I think the major accomplishment over the first year of the project was that we learned how to be a team of diverse, opinionated, and competent people that came together to create a house. We learned how to deal with one another, how to accomplish goals, how to work together, and ultimately we practiced and practiced the art of engineering and communication.

The project became a thousand times easier once we finally decided on a floor plan. If any team considering entering the Solar Decathlon in 2009 reads this blog, I would highly suggest sticking to a floor plan the first July of the competition. It was very difficult for the SCU team to do this, especially given our lack of an architecture school. This made finding the architectural mentoring and our learning process difficult. The nice thing about not finalizing the design until March, is that we went through so many iterations that this final version definitely makes the most sense for our project, the obvious down-side, however, was that construction did not start until June.

I wont give away too much of what is going on now. There is still a small competitive advantage to keeping our cards hidden. I know that, like us, all the teams out there are working very hard, and are extremely proud of what they are doing. Rightfully so, every competitor has a lot to brag about. What I am here to brag about today is the long, grueling road behind all of us. To get to where we are now, some amazing people have put in some super-human work, learned more than any class could teach, fought, cried, laughed, and ultimately formed a tight-knit team. I am so proud to have been a part of this process. I am so lucky to be involved with so many great people. For me, this project has been the hardest test of endurance in my life, but I know that it is one of the best experiences I will every have. More importantly, I know that there are some amazing friendships from this experience that I will never let go of.

I hope this brings a little sunny disposition to anyone reading this. I especially want to encourage the other teams out there. Santa Clara knows exactly how you feel right now. The long road behind us is definitely longer than the one ahead of us. I am excited about D.C. and putting our team and our design to the test.

greenies, techies, and everything in between

After the last few (very long) Solar Decathlon days full of house painting, steel drilling, tour prepping, and of course late-night construction site discussions on Wittgenstein and the essence of being (you never really know what will happen next in the Solar Decathlon), I think it is time for my first official blog post.

As I was riding Caltrain and Bart home from the construction site tonight, I was people-watching the corporate tech types with their smart leather briefcases rub elbows and share subway seats with the whole foods greenies toting timbuktu bags. (I myself am particularly partial to the bike-wielding business pros with their suit pants tucked into their socks.) As we rumbled along under the streets of San Francisco, I started thinking that the time is ripe to bring up some potentially controversial questions surrounding sustainability, technology and lifestyle.

As an anthropology major building a technologically-dynamic solar house, this is of particular interest to me, particularly because I find it nearly impossible to turn of my built-in “cultural observation” switch. I am constantly fascinated by the endless variety of “sustainabilists” and the diversity of ideas they have about the role of technology versus the role of personal lifestyle in moving our culture in a more eco-friendly and long-lasting direction. Some believe that we must completely re-evaluate and transform our culture to avoid catastrophe while others trumpet the past success of technology and its potential to preserve our culture and human life as we know and love it. So who is wrong? Who is right?

I say, neither and neither, both and both. Ambiguous, you think? I prefer “open-ended and full of possibility.” The greatest thing about sustainability is that it is a broadens rather than narrows our perspective on human experience. As a team, we are trying to show how simple and effective sustainable technology can be - so simple that people don’t have to change their lives to lighten their environmental impact. However, we are also building a solar house to demonstrate that evaluating how you live is important and to demonstrate the value of sustainable lifestyles that don’t cost a lot of money, or any at all.

Bear with me, there are variables in this post. They aren’t scary at all, or I wouldn’t have given them a second glance.

There is a formula people throw around about the environment:

I = P * A * T

I, which stands for environmental impact, is calculated by multiplying P (population size) by A (affluence, or, consumption) by T (technology). More technology results in increased environmental impact - which may have been true in the 1970s when this formula was written. Though I am by no means an expert, and I’m sure others have said this, but with the widspread use of sustainable technology, we may be able to move T from the numerator (bad…) to the denominator (good!) so the equation looks more like this:

I = (P * A * T1) / T2

In the new equation, T1 is old inefficient technology and T2 is new eco-effective technology. The more sustainable technology we use, the less negative impact technology will have on the environment. In the same vein, the less we consume, the less impact we will have on the environment. Like in any problem, working with one variable can help you make some progress, but addressing one variable won’t quite do it alone. Any thoughts?

Now that may even be something an anthropologist and an engineer can both agree on.

Perspective On Solar Energy Market From Spain

This is my first post on this blog and I decided that instead of talking about my involvement in SD2007 so far as a way of introduction would be typical and lame. So I am going to jump right into one of the more interesting aspects of solar energy today: The Economics (With a capital E).

I am currently on “vacation” - I am actually doing a significant amount of work - at my home in Spain. Yesterday I was talking to my father during breakfast about whether he should put solar panels in our house. He didn’t need too much convincing on doing the right thing or saving the environment; he knew all about what the planet needs. He was more concerned with the economics of the matter. What he said was, “How much is it going to cost?” and, “Am I going to save any money at all?”

I told him that in California, he would certainly end up breaking even and then saving some money on electrical bills. He wasn’t too thrilled with this modest form of investment. So I told him to go see the local solar integrator to get some facts and figures on the economics of Solar Energy. I was shocked and so was he. In Spain the electrical company is required to buy - actually buy, not just run your meter backwards - the power your produce with solar energy at over four times the cost of regular electricity. In addition to this, banks usually provide 80% of the initial investment with a very good interest rate.

When the salesman told us this and showed us some figures and economical projections, my father started smiling and I knew his accountant’s brain was crunching numbers. When we got home he grabbed his old-school HP 12-C financial calculator and cranked out the interest of such an investment. It came out to be above 16% - investing in stocks over 25 years yields about 8% and real estate averages at about 12% at best - this was a ridiculously easy decision to make. He is going to invest in solar.

Solar Farm

Not only is he going to install it at home. He is actually thinking about installing a 1Mega-Watt solar farm somewhere in the Canary Islands where the sun shines the most of all Spain.

Anyway, I thought it would be interesting to share how government policies can really have an effect on increasing our use of solar energy. In Spain, it is so profitable to go solar that people instead of putting in their homes, build solar farms that help the electrical grid specially on peak consumption.

3 weeks left

We have three weeks left, the tensions, and personalities of the team are heightened, but we are all confident we will succeed.  We are very excited to be the underdog, flying under the radar.  We’ll see what happens in D.C.
