Solar Oven


A hand-me-down from my friends Mark and Georgina, local gurus of sustainability. Mark had a couple extras from a demo day at his place of employment, and said, "I'll give you one if you're really going to use it!" No problem there.

The pic is of my first effort: a hastily prepared rice dish, put out around 4 PM, unsure if the sun would be hot enough in the last hours of this early May day. The rice came out of the sun at 6.30, perfectly cooked. It would have felt like a very pure and simple cooking experience if I hadn't needed to microwave the chicken stock we keep stored in the freezer. The lady of the house was not very impressed with that. If only I had an extra hour of sun, I would have been able to shun the nuclear option.

I have some unexpected disappointments to sort through. This is, essentially, an outdoor cooking method, one that my wife seems happy to leave to The Man. But, strangely, there is no smoke. There are also no special tools, no sizzling, splattering of fat, or poking of charred meat with forks. Really I think my disappointment comes down to a lack of fire. I should say, just to be clear, that my criteria for cooking with fire is that said fire be at ground level, not burning at a distance of one astronomical unit.

I can live with it, because with this smokeless cooking method, entirely devoid of splattering fat as it is, there is also no power being used ... so no draw on the power lines in the house, no burden on the grid, no demand generated on some coal-burning plant somewhere, and so no smoke near or far, which means no impact near or far. This is good.

I'm counting on the fact that I'm banking some carbon equity, and can soon plan a meal that involves solar-baked potatoes and veggies, with a side of grilled meat.

On the Nascent Science of Geoengineering

I'm no scientist. I'm just a guy. But I heard a scientist talking about geoengineering  on the radio the other day, and I'd like to say for the record that I do not agree. Geoengineering refers to proposals to manipulate the planet's climate in order to counteract global warming.  An example: spraying chemicals in clouds to make them more reflective thereby bouncing the sun's rays away from the earth. Another example: sucking carbon dioxide into big holes in the ground. Hmm.

Now, I like tools well enough. I appreciate well-thought-out and well-crafted technological solutions. Take hammers. Hammers are cool. Hammers do their job really well, and you can choose from a number of different designs depending on your work-style and end-purpose. Hammer designers have been working on better hammer designs for a long time, and at this stage, we'd have to say that hammer design and technology is pretty mature. And yet, we occasionally smash these modern, well-designed hammers into our thumbs and create problems for ourselves. Nobody can design all the risk out of our tools.


So my question is, how worried should we be that well-meaning scientists, as smart as they may be, are talking about designing planet-sized hammers to solve a global problem? Even if I believed that Scientists (that group of people who totally agree all the time on how things work ... right?) could understand all of the large-scale mechanisms at work in global climate patterns, which I don't really believe, I'm not sure I would want them trying their hand at a global solution. What if the hammer slips? We're not talking about a big toe here. We're talking about the Earth.

The Geography of Hope



Some months ago, I posted an essay about how a ranger scolded me for walking 10 feet off the trail at Palo Alto's Arastradero Open Space Preserve. This preserve is in the foothills of the Santa Cruz Mountains, a wide-open place where one wouldn't expect the kind of "keep off the grass" rules associated with strips of city park. The title I gave the essay communicated my feelings on the matter ("Signs of The End").

But, I can admit now that I was of two minds on the matter. It still seems ridiculous to be told to stay on the trail in such a wild place. But soon after I wrote the piece, I felt a prick of conscience, and a sense of responsibility to tell the other side of the story. Why? Because I keep going back to Arastradero ... on foot, on mountain bike, alone and with my family. I find myself enjoying that same trail, and many other trails along the San Francisco peninsula again and again, and I began to have new thought share space with my semi-righteous indignation. I realized that I have very little to complain about. I live in one of the most expensive real estate markets in the world, in the high-tech center of the modern world, and yet ... I am surrounded by simply beautiful natural spaces, forever preserved against development or modification beyond the laying of trail. I have in fact enjoyed open space along the Peninsula for my whole life, in all four seasons, in rain and shine, day and night. I've slept under oaks, prayed on benches, sat writing in journals, and stared without a thought into wilderness ... all in settings that allow my heart and mind and soul to drop their guard and to breath.

Room to breath. This is one of the themes in the language of open space. You come across the phrase frequently in the history of one of the largest of the agencies that oversee open space in the San Francisco Bay Area, the Midpeninsula Regional Open Space District. I wanted to get to know this organization, to meet the people who keep this land for me, and to learn what it takes to preserve open space in a region that the rest of the world associates with high home prices and high technology. How do they do it?

I confess that when I met with Leigh Ann Maze of the OSD, I was looking for dirt (no pun intended): I wanted to hear all about the fights over who gets the land and how it is used. I guess I imagined a great battle over each acre: developers and technologists on one side, and sandle-wearing soldiers in the open space army on the other. Maze couldn't satisfy my need for drama. She said it might get a little hot in the nitty-gritty negotiations over a particular parcel of land, but she's not really aware of any great philosophical divide on the Peninsula. The overall impression I got from talking to her is that the OSD enjoys a lot of favor in the Bay Area. She suggests that open space is a part of what attracts people to live here, and that even the developers recognize that being able to see trees on the mountains increases the value of the homes down in the suburban sprawl between highways 101 and 280.

So it may be that some experience it as a tension, and others as harmony, but either way, there's no argument over whether it is good to have open space here at the end of America's westward expansion. You might expect to see an insulting profusion of development here, in the same way you see great mountains of boulders at the terminus of ancient glaciers. After all, people keep coming .... Instead, land dedicated to open space is increasing, not as much as in the early days, but still increasing each year. Anne Koletzke writes in Peninsula Tales and Trails, a guidebook to the district, that the Bay Area has one of the largest systems of public open space to be found in any urban area in the United States.

But it wasn't always that way. Journalist Jay Thorwaldson, in the foreword to Peninsula Tales and Trails, describes looking down, as a youth on horseback, from the ridges of the Santa Cruz Mountains as the "valley's endless apricot and prune orchards [gave] way to homes and highways in a sad, but seemingly inevitable, roll of market demand and economic reality. Before silicon became the heart of computers," and a significant driver of development for the region, "this was called the 'Valley of Heart's Delight.'" In 1970, the threat was very real. But Thorwaldson was on hand to document a local, citizen-driven campaign to preserve open space. He himself influenced that campaign through editorials which urged these early environmentalists to find a way to buy the land they wanted to protect against development, a strategy also promoted by Wallace Stegner, a Stanford professor and novelist who contributed important ideology to the movement. If you want to preserve open space, the argument went, you have to own it, so that you can keep it open for ever.

Today the OSD owns over 55,000 acres of land, most of which can be explored by anyone who lives in, or visits, the Bay Area. When land is purchased, the first goal of the OSD is preservation, ensuring that the environment in and around the land is protected. These concerns always extend beyond the boundaries of purchases. Wildlife (from ubiquitous deer and squirrels to endangered red-legged frogs) pass through open space preserves and policies within the boundaries must account for the through-traffic. The course of streams in preserves can affect local watersheds and species (including our own species) many miles downstream. At times, early 'improvements', such as logging roads (called by the OSD, 'cultural resources'), need to be reversed to halt the pernicious effects of erosion on the ecosystem.

A very few times, the OSD closes a preserve to human visitors. But the "goal is to keep them open," says Maze, though always with limited provision for human comforts. "We set ourselves apart from other parks: we like to keep the infrastructure to a minimum. ... You'll see dirt parking lots and pit toilets, but no barbecues, play structures, or picnic tables ... the whole system only has one overnight campsite. ... We call what we do ecologically sensitive recreation and education." This emphasis on letting nature be, and not filling it with soccer fields, golf courses, or other recreational infrastructure, is summed up by Wallace Stegner in his Wilderness Letter, who asserted that preserving natural open space has "no more to do with recreation [than] churches have to do with recreation." We need, he says, to learn the "trick of quiet" that our ancestors knew from time spent in the big empty plains. "We could learn it too, even yet; even our children and grandchildren could learn it. But only if we save, for just such absolutely non-recreational, impractical, and mystical uses ... all the wild that still remains to us."

Adding to the delicate balancing act that is managing a piece of nature, the OSD is a public agency and so is accountable to local public opinion, state and federal governments, policies including the Endangered Species Act, and other rulebooks overseen by agencies such as the U.S. Fish and Wildlife Service. "There are a lot of layers," says Maze, "even for one little project of putting in a bridge ... we have to get permits from cities, counties ... and the public always want to weigh in. ... Ultimately it's the public's land; it's your land, your trails."



With all these obligations to balance, the OSD seems to work really well. They do a great job communicating to the public -- they have a quality website, good-looking publications, and were willing to talk to a snarky blogger like me (that "end of the world" post was not much of a calling card). And, of course, they do a very good job stewarding the land. My experience of the preserves is that they are consistently clean, accessible, and well laid-out. I know that takes work, even when the bulk of the land is trusted to natural processes. Finally, and maybe most impressively, from what I've seen, it appears the OSD manages and spends their considerable budget wisely.

It doesn't mean it's all sunny skies over the preserves though. The downturn in the economy has affected the OSD, like it has every other business. Grants and private donations have dropped, and to add insult to injury, even though the District manages it's budget very well thank you, the State of California is exercising it's "emergency right" to take money from "special districts" to deal with it's own budget shortfall. They are borrowing roughly 2 million from the OSD, "which legally they need to pay back," says Maze (uh ... good luck.) When I asked if the money taken from the OSD would at least go to save some of the state parks that are expected to close (again, good luck), Maze couldn't say, and she showed a remarkably goodnatured attitude towards Sacramento. "We look at it as an investment in the state."

For all this organizational complexity, federal policy, resource managment, state budget trouble, and, yes, the threat of development on currently un-preserved land, the OSD does an amazing job of giving the people exactly what was hoped for some thirty years ago: room to breath.

And though I don't like fences in the wild, I recognize the difficulty of protecting land, especially when the land in question is surrounded by forces hostile to it. Regardless of the relatively harmonious relationship between open space and ... crowd-space on the peninsula, I know that if the fences came down, the land would be lost. So I'm thankful for the activists who fought to purchase land to preserve it, and I'm thankful for the Midpeninsula Regional Open Space District, and other powers that protect land for me, even if it means there are some views I have to enjoy from the trail.

We simply need that wild country available to us, even if we never do more than drive to its edge and look in. For it can be a means of reassuring ourselves of our sanity as creatures, a part of the geography of hope. -Wallace Stegner, The Wilderness Letter



A (low) tech writer principle: invest in the things you love. If that loose community of nature lovers back in the 70s had only come together to complain and had not put their money where their collective mouth was, the land between San Jose and San Francisco would be very different today, and we would all have a lot more to complain about.

A lover's quarrel

My friend Heather writes a beautiful, honest post about returning home to Georgia and the tension of how things change. She talks about Georgia like one might a former boyfriend--winsome memories of lovable qualities, and a hard encounter with all the reasons why it could never have worked out .... Her clear-headed reflection on the imbalance in the urban/rural relationship is itself balanced and evocative.

When I return, I feel...I feel betrayed. Atlanta has sprawled beyond her rightful and necessary boundaries. Or you could say the symbol Atlanta is of urban commerce has overrun its banks and flooded the rural landscape that gives that commercial river the right to flow in the first place. I'm not naive enough to say that commerce is bad or that cities are bad but I am principled enough to say that when the balance of urban and rural gets knocked off its fragile footing both sides lose.



From Heather's blog, Garden Street Farm: A song of you comes as sweet and clear as moonlight through the pines.

Signs of The End

Signs that we are in the last days: police action in the wild-lands of Palo Alto. On the very same day as my encouraging visit to Peet's, I was walking in Arastradero Park, in the foothills above Palo Alto. This is no city park: there are no lawns, no landscaped flower-beds, no bandstands--just 10 miles of beautiful trails.



A great effort has been made at Arastradero to return this suburban open space to wilderness. But wild is as wild does.

After shooting some pictures of wildflowers just off the trail, I was met by a ranger (where DID she come from?) who scolded me for leaving the path--a violation of park rules. This picture is the evidence of my shameful transgression.

OK, I know, because she told me, that this park gets "loved to death", and that the rules are there to preserve this natural beauty for future generations. But the whole experience made me feel like I was in a museum, or a zoo, except in some zoos you get to go through the fences and pet the goats. Look at that trail. It's beautiful. Isn't it spoiled, just a bit, by a "Keep Off The Grass" sign?

I've written about this kind of madness before. If I cut off a trail at the same place as a hundred other people, or if I choose to walk just to the side of a trail to avoid the mud in the low track, then I would be contributing to visible wear on the ecosystem. But is it really going to scar the planet if I leave the trail at a random point to walk out in the grass a bit for a different view? Please.

No matter what justification is offered--and it all has a kind of grim logic about it--who can be happy about such barriers arising between human beings and nature? There are many more disturbing things in the world, but this still feels to me like one more sign of the apocalypse.

Andy Goldsworthy on Tech


Sculptor Andy Goldsworthy writes on his process: "The work itself determines the nature of its making. I enjoy the freedom of just using my hands and 'found' tools - a sharp stone, the quill of a feather, thorns. I am not playing the primitive. I use my hands because this is the best way to do most of my work. If I need tools, then I will use them. Technology, travel and tools are part of my life and if needed should be part of my work also. A camera is used to document, an excavator to move earth, snowballs are carried cross country by articulated truck."*

I am very comfortable with this pragmatic approach to technology. The problem (here begins my opinion) is not technology, in itself, it's in the adoption of technology, or technique, as "the way" (or even "the best way") to fulfill a desire. When a community (artists, for example) discovers a piece of technology that makes a part of their job easier, or a technique is developed that introduces efficiencies into a process, this is not a bad thing, per se. But if technique precedes meditation, exploration, and inspiration, then creativity withers.
