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.

Grooming Habits and The Cult of Innovation

bag

My Bag has one pocket, and it's BIG. I like simplicity in my bags. I do not like complexity. My bag used to have a single inside flap, stitched to the top lip of the opening, with an assortment of little pockets for organizing stuff, but I removed it. It's not that I don't like being organized: it's just that I don't really like having someone else's principles of organization forced on me. The organizer pocket that was stitched inside this bag had a couple pen slots (I carry more than that and so I use a pencil case, which you can see in my profile picture), a wide pocket sized for something like a palm pilot (which most people now keep in a box in a closet, while they wait for the museum to call), a tinier fleece-lined pocket for a phone or media player (which is now a single device, and holstered to my strap for quick access while riding), and other miscellaneous slots that simply didn't fit the stuff I have. So out with the perma-pockets! The bag's a little lighter, it sits open more readily because there isn't a heavy array of pockets pulling the lip of the bag down, and is ready to be customized according to my needs.

Even when it left the factory - organizer pocket intact - my bag was downright simple compared to the modern daypack. Daypack design has gotten a little silly: the more specialized pockets, ports, sleeves, techy functions, fobs, and space age suspension technology a bag has, the more X-Treme you are, and the more money you will be separated from and ... the more doomed you are to throw away the bag as soon as your needs change. Think of it: you buy a new bag to fit your stuff. Your stuff breaks, or gets replaced with new stuff, or you stop using this stuff, or somebody invents a new piece of stuff that has an entirely different form-factor ... then you have pockets and features that are no longer relevant.

What if you don't have an MP3 player? Or you want to put it somewhere other than the specialized, padded media-pocket with a custom port for the headphones? What if you buy a bag with a padded pocket for your 12-inch laptop, then upgrade to a 15-inch? What if the water reservoir that came in the special insulated hydration-sleeve breaks or gets funky (it happens) and the new one you buy has the tube-thingy coming out of the wrong part and so doesn't reach out of the special hydro-hole and so on?

Custom pockets and padding and extra zippers add weight and more points of failure, and often stay empty for want of the Right Sized Thing. My bag, a Timbuk2 large Classic Messenger Bag (made in San Francisco), on the other hand, is insanely durable and beautifully flexible. In the one pocket of my bag, I have at different times carried a case of beer and snacks (ahem, to share), a full-size bike stand (a four foot long box ... it stuck out), camera bodies and multiple lenses, groceries, full picnics for a family of four on the beach or in the mountains (then all the rocks and stuff we collected to take home), and small ad hoc reference libraries. Basically, I can carry more in my bag than is wise, comfortable, or safe for anyone to carry while riding a bicycle. Of course when I only have a few things in it, it collapses to fit. It has no frame or foam suspension. It's a bag: it has the shape of the things it is carrying.

I do have the need to organize and carry small things: bike tools, pump, lights for night riding, food, extra clothes, books, journal, pencils and pens, and various other possibles. I have cheap little ditty bags and stuff sacks for all the things I carry, each one perfectly suited to my purposes because I chose it. If my needs change, I swap out the cheap bags. I put my laptop in a neoprene 'sleeve' that fits it like a glove. If I were to buy a bigger laptop, I'd get a different sleeve to fit it. What happens if the sleeve is stitched into the bag? And for that matter, what does the pocket do when you leave your laptop at home? What else do you put in a permanent, rectangular, foam-padded pocket? A very carefully folded sweater?

Bags with tons of pockets are also a serious liability in the rain. Bags with a lot of pockets and openings either have to use waterproof zippers and specially sealed seams (every stitch point is a point of entry for water in a downpour) or must be under a waterproof cover. My bag has one large, vinyl-coated, rain-proof flap, with no zippers to fail. Simple, beautiful, and durable.


(One extra provision I make for the possibility of really bad weather is the stuff sack that holds my rain gear: this bright orange bag is also waterproof. If the weather turns bad, the rain gear comes out and anything really sensitive to moisture goes inside the bag as extra insurance against water finding its way in.)

(low) tech writer principles. Rigid compartmentalization and design complexity limit flexibility and shorten the lifespan of a thing: complexity wears out its welcome sooner than simplicity. Complex things slow you down, require more maintenance (of a more specialized kind), solve problems you probably don't have, and cost more in the bargain.

Simplicity in design is more enduringly functional, flexible, adaptable, durable, and inexpensive (both on the day you buy it and when you need to repair it).

Old Atlases, Printed Maps

There is another book that I like to put on my music stand (see my previous post on old dictionaries): my old Times Atlas of the World, found in a used bookstore 10 years ago. It's old enough to show a divided Germany, Leningrad-in-the-USSR instead of St. Petersburg-in-Russia, and countless other geo-anachronisms, but oh, is it beautiful to look at. And really, do we care what the politicians say about where the borders are, or whose ego is institutionalized on the city masthead? Yes, ok, sometimes we do need to know such facts. But that's what Internet maps are good at. I am well aware of the other ways that computerized maps and atlases are superior to the soon-to-be obsolete printed variety: they are up-to-date (i.e. -to-the-minute), truly comprehensive, and augmented in infinite ways with personalized layers of meaning (see the history of natural disasters for the city you're visiting, or see where the coffee shops are).

Claims of comprehensiveness and currency in a printed atlas always assume you will buy the latest version, which, if you are buying a nice atlas, may run you a few hundred dollars. And why would you not buy a nice atlas? You can get ugly atlases online. So, my recommendation for the killer combination? A nice old Atlas (cheaper, probably prettier, and still 90% accurate) and the Internet to supplement your old beauty with the latest facts. The picture above, of Oban, in Scotland, is from my old Times atlas (be sure to click on the image to see a bigger version).

I love maps, and love studying maps of a place before, and after, visiting it for real. My introduction to maps was via the topographic maps produced by the United States Geological Survey, used by everyone from soldiers to miners to hikers for navigating in the wilderness. There was a USGS office in Menlo Park, a few miles from where I grew up, so we got to browse the beautiful, poster-sized, four-color maps whenever we wanted. On a trip to my wife's family home in Greece, I visited that country's equivalent of the USGS, the Greek Army Mapping Office. My brother-in-law and I were planning to climb Mt. Olympus, and I also had plans to camp out in the Peloponnese. When I asked for the maps that covered the westernmost finger of that peninsula, the army officer looked at me suspiciously. He fetched his commanding officer and they grilled me: "Why do you want to go there? There is no camping there! What is your business?" I tried to assure them (with the help of my Greek brother-in-law) that I was just going to find a place to put down my bag on the coast and enjoy the sea and stars. They never did give me that map. I forgot about the incident until I was awakened on my hillside perch near Koroni, overlooking the Mediterranean, by what sounded like bombs going off. What had sounded like bombs going off was in fact bombs going off .... Turns out the Greek Air Force likes to practice their aim on the little island of Skhiza, which was just about a mile south of my sleeping bag. I watched jets looping and dropping bombs for an hour. No wonder the army guy was suspicious.

Since I can't show the map with Skhiza on it (ahem) ... here is my Greek Army Map of Cape Tenaron, about 40 miles southeast of my camping spot near Koroni. Maybe nothing is as interesting as being woken up by jets dropping bombs at the foot of your sleeping bag, but the topo map below shows the tip of the Mani Peninsula, itself a very interesting place: in the cove near the southern end, surrounded by wind-torn, razor-sharp white rock and ancient ruins, is the cave of Tenaron, the mythical entrance to Hades.



Strangely, USGS topo maps were the thing that reignited my interest in computers, after many years of abstinence: in the mid-nineties, a San Francisco company, Wildflower Productions (now owned by National Geographic), was scanning all the topographic maps for the United States, in various scales, digitally stitching them together, and adding tools for searching and customizing. When I first got a look at their product on the shelves at REI where I worked, I called the company and asked them what I needed in my new computer (the one I didn't have yet) to run their product. At the time, I didn't care what else the computer could do.

I still have a soft spot for this product because it's based on pictures of real maps, made to be held in your hand. The computerized version allows me to look at topo maps for anywhere in the country, and of course you can't own that many printed maps. I understand how computers add value here. But I still say printed maps and atlases are so much more beautiful and satisfying to hold. And they provide much the same opportunity for serendipitous discovery that a printed dictionary does, as I detailed in my previous post. The maps in my world atlas are produced by the famous John Bartholomew & Son cartographers in the UK. Their maps, especially the old, hand-lettered ones, are so pretty to look at, and so clear. Am I repeating myself?



If you can afford the already-obsolete current edition of the Times World Atlas (obsolete, because world atlases go out-of-date about as fast as newspapers these days), here is a link to the Twelfth Edition of the Times Comprehensive Atlas of the World. But my strong recommendation is to search your local used bookstore for an older version, if only for the joy of the maps.

More Homemade Stuff - Not Just For Hippies

If Panasonic were to make a lens hood for my LX3 digital camera, it would probably cost somewhere in the neighborhood of $50. All the accessories for this camera are ridiculously expensive.


I wanted a way to protect my little camera from the rain and ended up with a perfect lens hood in the bargain, for about 2 dollars and a half-hour of work. The project was featured on instructables.com (where you can read about the benefits of the hood, and the process of customizing a $2 piece of plumbing for my high-end digicam):

Digital Lens Hood / Rain Hood on instructables.com

One of a number of clearing houses for the DIY set, instructables.com is a great place to find elegant (or funky) ways to solve any problem you can think of, usually for cheap or free, from recycled or otherwise lowtech stuff. Make Magazine (and their Web space and blog) also features daily projects for solving problems in ways that will save you lots of money and give you lots of low-tech satisfaction: solve a problem by making something and you are beating a socioeconomic system that only knows how to offer prepackaged, mass-produced solutions for high prices.

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.
