Glass cabin retreat

Not only are professionally-made tiny home videos entertaining to watch, but I believe they also help "spread the message" to a wider audience who may be initially drawn to the narrative behind the building rather than the structure itself.  One of the things I particularly enjoyed about this story is how during their travels they continuously searched for the perfect (reclaimed) windows, each of which has its own story.

As for the cabin itself, I'm intrigued by their extensive use of glass. One of the biggest advantages is all that glass will make it feel like you're outside in the woods even when you're inside the cabin.  They'll get plenty of natural light, as well as a myriad of interesting light patterns as the sun rises and sets each day. There also should be plenty of solar heat gain (assuming windows are oriented properly), reducing or eliminating the need for electricity and/or gas for heat. Furthermore, single-paned windows like these can be obtained very inexpensively (their cabin was built for ~$500) as home owners replace them with more energy efficient windows.

While it's great as a retreat, which it apparently is, or an artist/yoga studio, a structure with so much glass may not be ideal as a primary home as it can frequently be too hot (excessive solar gain) or too cold (heat loss through conduction, convection, and radiation). While awnings, shades, and curtains can help control solar gain, reducing heat loss in such a structure, especially with inefficient single-paned windows, can be challenging. One solution might be to install some type of thermal mass inside the cabin, like a Trombe Wall, which absorbs heat (solar radiation) during the day and then slowly releases that heat throughout the night.

Tiny Snapshot: Little Free Library

I recently saw this 'Little Free Library' in Atlanta (GA). Turns out it's actually part of a loose global network. While it might not work in every locale, this is still a great concept which can be implemented relatively easily, and help transform street blocks into communities.

Lodges and privies along Vermont's Long Trail

Earlier this month I was fortunate to spend ten days in Vermont with friends backpacking a couple of sections (Mt. Mansfield & Camel's Hump) of the historic Long Trail. While the peaks may seem tame by Pacific Coast standards (Mt. Mansfield's peak is ~4393 ft, the highest point in VT) the trail is fairly challenging with ladders and rock scrambles requiring use of hands. When it rains the water courses down the trail making it difficult to get solid traction on the rocks. Still, the natural beauty, including alpine tundra, and amazing 360 degree ridge views of Lake Champlain and the White and Adirondack Mountains make it well worth the effort.

The Long Trail, which traverses Vermont's length, is the oldest long distance trail in the United States. The non-profit Green Mountain Club (GMC) started developing the trail in 1910 and still maintains it today.  In addition to the trail itself, the GMC manages a set of rustic lodges and composting privies that hikers, as well as skiers and snowshoers in the winter, can utilize. The lodges we stayed in were generally constructed early in the trail's history and more recently renovated. They're small and lack plumbing and electricity, but are actually quite comfortable. The lodges all had lofts and could accommodate far more people than you would imagine: as more hikers show up everyone just squeezes in to make room like a cozy clubhouse in the woods. It's great to meet and talk with different hikers before everyone goes to sleep or heads to their next destination in the morning.

The composting privies were surprisingly clean and odor-free. I attribute this to many years of experience under the GMC's belt, dedicated caretakers, and a knowledgeable, respectful user base. The relatively simple structures admit fresh air and natural light while still providing sufficient privacy. Bark mulch is provided as a cover material to reduce odors, absorb liquids, and contribute carbon to the composting process. The biggest challenge is apparently the excess moisture from urine. Hikers are encouraged to urinate in the woods instead of the privy, but some seemingly prefer to take care of all their business in one sitting (so to speak).

Tiny surfing tender at Mollusk

I'm not much of a surfer, but I still enjoy hip surf shops which often feel more like art galleries than retail outlets. This interesting little boat is located in Mollusk Surf Shop, a few blocks from Ocean Beach in my Outer Sunset neighborhood. While the boat probably wouldn't survive the nearby surf it's elegant design, woodwork and glasswork look great in the shop.

Outdoor screening of TINY in downtown San Francisco

Last night I enjoyed an outdoor screening of the entertaining short film TINY - A Story About Living Small in a downtown San Francisco alley. The film, which recently premiered at SXSW 2013, was sponsored by the community nonprofit SPUR and is part of the upcoming SF Green Film Fest (which includes a number of intriguing films). Squeezed into a narrow alley amongst tall downtown buildings with an almost-full-moon in the background and a SolMan portable solar generator powering everything, we watched the story of a couple building and living in a tiny home.

I was selfishly hoping the movie would be a how-to about building a tiny home, but that probably wouldn't appeal to the general public. Instead, it's an interesting look at the ups and downs of building and living in a tiny home as well as brief interviews with a variety of people involved in tiny homes. It's actually a great introduction to tiny homes for anyone either unfamiliar or just starting to consider them. The screening even concluded with a Sundance-style panel discussion where the filmmakers along with Jay Shafer answered audience questions.

"Tiny Cabin, Giant View"

I'm fortunate that both my parents continue to clip out and send me interesting articles from the various publications they read. I particularly enjoyed a recent Wall Street Journal article about a tiny, idyllic cabin in the Sierra Nevada mountains outside Tahoe. Snowboarder Mike Basich built his home from granite stones and wood he collected from his property and milled himself. The off-grid cabin, which is several miles from the road, also boasts a fire-heated hot tub and his own personal ski lift. Impressive and inspiring!

While skiing Canyons Resort this past Monday I enjoyed seeing the collection of tiny buildings scattered around the mid-mountain area. They help make the area feel like a friendly little Alpine village.

Tiny home goes skiing

There are a lot of tiny home videos that showcase the structure or highlight parts of the construction, which can be an invaluable resource for future tiny home builders. However, one of the aspects often missing from these videos is the passion for whatever the tiny home enables: art, music, travel or, in this case, skiing/snowboarding. People are drawn to tiny homes for a wide variety of reasons, but one of the most common motivations I've seen is a desire to focus on things for which the owner is passionate while avoiding the financial and psychological encumbrances which "traditional home" ownership may present. To be sure, this professionally produced piece will no doubt appeal to anyone, like me, who loves skiing and the epic skiing footage found in Warren Miller films. It also, however, effectively conveys the notion that the real benefit is not the tiny home itself, but the journey and the experiences and relationships the home enables.

Outdoor Research and others sponsor extreme skiers Molly Baker and Zack Giffin and helped produce this video as well as well as the Tiny House Tour episodes. Fortunately, the commercialization is relatively subtle. Actually, I think it's great to see a reputable company like OR indirectly promote tiny homes on their home page even if the end goal is simply to sell more clothing and gear. Design decisions may have been informed by the tiny home's role as a maximum-occupancy ski hut and branding opportunity. Curiously, there is no bathroom or shower, but that may be because they needed the space to accommodate five adults (cameramen included). The beautiful little wood-burning stove is probably great for drying ski gear, but the stove's footprint, including clearance from the walls, can make it impractical for many tiny home owners. The element I particularly like, though, is the unique stairs going to the loft. The woodwork is magnificent, yet the stairs are simple, sleek and keep the room open instead of acting as a barrier. The stairs look like they function effectively as seats or temporary spots for gear or drinks.

Sidebar: Warren Miller was a pioneer of documentary ski films starting with Deep and Light in 1949. He produced, directed and narrated his films until 1988 and remained involved until 2004. Interestingly, he got his start in the 1940's while living in a trailer at a ski resort (Sun Valley) parking lot, not unlike Molly and Zack.

Plastic bag bans, health, and the environment

I was very proud when San Francisco in 2007 became one of the first major cities to ban plastic checkout bags. Lightweight and durable, they're almost irresistibly convenient, but these same characteristics make single-use plastic bags so pernicious in marine environments where they persist beyond our lifetimes, traveling currents and endangering marine life. Reusable grocery bags seem like a no-brainer, but continuing buzz based on a couple of university studies now has us concerned reusable bags harbor potentially harmful bacteria. Let's forget the questionable methodology and conflict of interests (one study was funded by the plastic-bag-friendly American Chemistry Council), and assume reusable grocery bags, like just about anything that touches food, can potentially harbor bacteria. Fortunately, it's actually fairly simple to eliminate any threat freeloading bacteria might pose through cleaning (by hand or machine) or by simply letting the inside out bag sit in the sun for a few hours.

While bacteria can generally be managed with a dollop of vigilance, the reusable bag proposition becomes more complex when you consider their production. For example, cotton bags may be biodegradable, but their production requires resource-intensive cotton: an interesting British study found that cotton bags require 131 uses to equal the global warming impact of conventional plastic bags. Repurposing containers as grocery bags is the ideal. The truly committed can even knit their own reusable bag from discarded plastic bags. The bottom line is we should consider the entire life-cycle of reusable bags including production, use/cleaning, and disposal. Beyond that it's a matter of personal preferences and habits: if it's easier to store and bring a certain type of bag on a consistent basis then it's probably a good choice.

BioLite stoves

BioLite Campstove

I'm always interested in camping equipment innovations which reduce weight/size, increase efficacy, and/or eliminate the need for other equipment. While I'm not one of those guys always sporting the "latest and greatest" equipment, I do focus on significant technology improvements. Recently I've become intrigued with the BioLite CampStove which burns wood efficiently (with the help of an integrated fan), and converts thermal energy to electricity to power the fan as well as charge small electronics like cell phones. In addition, the CampStove technology and funds from CampStove purchases enable the company to provide those in developing nations currently cooking with unhealthy open fires with a cleaner, low-cost, electricity-generating cook-stove, the BioLite HomeStove.

Gas camp stoves can be convenient, but the gas canisters are bulky, bad for the environment, and must be purchased at stores. Wood burning stoves are lighter and more sustainable. There are wood burning camp stoves that are less expensive than the $129 CampStove and lighter (~5-10oz vs. 33oz), but they require you to blow into the stove fire constantly thereby breathing in acrid smoke. Not pleasant. If the CampStove's fan works as it should then it will stoke the fire for you, and require less wood gathering since the combustion is more efficient (YouTube reviews). The thermoelectric generator converts heat into electricity not only to run the fan, but to charge small electronics. That's great for emergencies like Hurricane Sandy, but I leave electronics behind when I'm camping. I hope to see BioLite offer a similar but lighter, less expensive power module that removes the USB charging components.

The technology along with capital from sales of CampStoves enable BioLite to provide low-cost HomeStoves to developing countries. This social entrepreneurship could significantly help billions of people who daily gather wood and cook over open fires, inhaling smoke and carbon monoxide from incomplete combustion. The HomeStove, which is in pilot programs around the world, could reduce wood required as well as emitted smoke and CO while charging cell phones or small lights (very important in rural off-grid villages). It's still early, but the impact HomeStoves have across the globe could be monumental.
