New Solar PV Technologies

In a recent exchange with my former high school physics professor and now good friend Dan Heim, we discussed the current and forthcoming technologies applied to solar photovoltaic power generation, as follows:

DAN RESPONDS
I couldn’t find an actual spectral diagram, but if you go to The Physics of Photovoltaic Cells and scroll down to Silicon Photovoltaic Cells you get some idea. I happen to know that standard silicon PVs get most of their energy in the 500-700 nm range (blue-green to red). Not unlike plants that photosynthesize, curiously.

Outside that range, efficiency drops, and more of the incident solar energy is transformed into heat. It all comes down to the band-gap the electrons need to jump in order to become “available” for conduction. That’s why even the best silicon PVs are only slightly more than 20% efficient.

But there’s a lot of work being done to increase that wavelength range and improve efficiency using different dopants to get different band-gaps. The available solar energy ranges from infrared to ultraviolet, which normally just becomes heat in a PV cell. The prospect of a “full range” PV cell is something many researchers are working on.

Check out An unexpected discovery could yield a full spectrum solar cell

I’ve also read about some work exploring the use of organic compounds, as well as nanotechnology, to boost performance, but they don’t provide many details.

Regarding mirrors under the bifacial PVs, most definitely that would boost output. How much more you’d get with an actual mirror, compared to say shiny metal or white flagstone is hard to estimate. There’s also the problem that mirrors are more fragile, susceptible to hail damage, and would need to be kept clean. A layer of fine dust would decrease their performance to the point where a mirror might not be much better than shiny metal –Dan

A Growingly Small World

That may not be the most correct English grammar, but what I meant is true.

Following on the words of my prior entry, it is both incredible and wonderful that in any given day, as with today, I have used Skype to maintain a realtime video conference with a friend in London, England, while updating a website hosted in Montreal, Quebec with realtime feedback from a co-Director in South Africa while coordinating with an IBM colleague in Singapore and a former co-worker in Victoria, British Columbia. It is likely too that I will receive email or text messages from Kenya, China, and of course much closer to home, any of a dozen States in the United States.

This interaction combines international standards across three desktop operating systems (Linux, OSX, Windblows) and who knows how many servers which push the data, headers and packet checksums through countless routers, telecommunications server blades (most likely PowerPC running Linux), and eventually to their recipient.

It reminds me of an article I wrote for MacNewsWorld in 2004, A Ghost and the Machine in which I drew a correlation between distant recipients of internet transmissions and the ghosts of times past.

Maybe some day, when the science fiction of Philip Dick becomes science fact, the differentiation between what we do with our computers and what we think is greatly reduced, the ultimate, seamless transmission of our experience in this world, becoming the experience of another.

And those experiences, if digitally stored in the richness of a three dimensional, tangible memory could themselves become ghosts if they were to escape the confines of their database cell, roaming the planet’s networks seeking their long-since deceased creator.

Goodbye Telephone, Hello VOIP

Bye-Bye Ma Bell
The days of the Bell spin-offs are, as we know them, numbered. Over one hundred years of telephony services and the line between voice, data, and entertainment is just a few years from being completely washed away.

There is no need for me to reiterate the history of the telephone nor the transition from analog to digital telephony services as there are a number of in-depth Wikipedia entries.

But what is important to note is this — you have not, for many years, been hearing the voice of your business associate, family member, nor friend who is speaking to you from across the nation, nor even likely from across town. Rather, you are hearing a digital recreation of the voice.

The transition from analog to digital enabled a far greater number of phone conversations to be maintained over any given set of copper lines than with analog, while at the same time improving quality and allowing for the transmission of data (fax, email, web, music, video, etc.).

VOIP
What is coming next is the movement of voice data over a much broader spectrum, using the internet cloud as an indirect yet far less expensive means of moving a digital representation of your voice from your phone to whomever is listening, anywhere in the world.

This is called Voice Over Internet Protocol, or VOIP. Originally made possible from computer-to-computer using open-source software such as Asterix, Skype introduced VOIP communications which enable computer-to-computer, computer-to-phone, and with the rental of a number, phone-to-computer calls for free or very low cost.

In the U.S., Vonage offers a no-brainer means by which you may tell Qwest, AT&T, or Southern Bell to go hell, and conduct all your phone calls using DSL, cable, or wireless broadband. Yes, you will need to pay for the broadband service, but you can remove the phone services and use VOIP instead.

The future of telephony services is the same as that of residential internet and home entertainment–service providers will compete for the highest bandwidth data pipe bundled with the lowest cost mix of services.

Mobility
A friend Jeff Moe (super hacker extraordinaire) had years ago rented phone numbers (not services, just numbers) in a number of countries where he configured Asterix servers which allowed his friends in those countries to dial local numbers which auto-routed to wherever he was residing. He could be holding out in Argentina and answer a call placed in Southeast Asia and no one incurred long-distance charges.

That is possible now for those of us who do not harbor Jeff’s ubergeek abilities. While Skype offers physical phones which receive your local number no matter where you are in the world (as long as you are within the reach of an adequate wi-fi network) the Vonage VOIP adapter which may be connected to any internet connection, anywhere in the world, allowing standard handsets to receive and make calls at very low rates.

Skype and Vonage (along with TruPhone and others) also offer free iPhone apps which allows similar functionality for your iPhone or iPod Touch.

If you don’t want to pay AT&T ridiculous prices to use the iPhone, use an iPod Touch as your phone instead. It’s simple:

1) Purchase a headset with microphone.

2) Then download Skype or Vonage VOIP apps from the iTunes Store.

3) And within seconds you will be making your first call.

While you cannot receive calls to your iPod Touch using Vonage, you can if you subscribe to Skype’s caller ID service which will give your Skype call the appearance of a call from your phone. And what’s more, Skype provides for auto-forwarding to any number, even when your Skype application (nor your laptop) are on. It really works!

And true to Jeff’s hand-built network, Skype account holders can have a number in any country in world, meaning someone local to that country can call the number for free, and it will auto dial their Skype account, even auto-forward to their local number. Charges do apply, but what a great way to remain connected, even build an international company without ever leaving the office.

What comes next?
The strong-hold that AT&T and Apple hold on the PDA market is going to unravel as Google’s Android is now being embraced by several major phone manufactures, including Acer, Motorola, HTC, Samsung, and Sony as an open-source operating system for mobile phones.

What gets really exciting is when you use an Android phone to connect to a 3G (or forthcoming 4G) service and then route that connection through the built-in 802.11 transceiver to create a local wi-fi network for home and mobile office use.

Whether at home, in the office, camping on the fringes of civilization, or moving at 75MPH down the Interstate, you may use your mobile connection to build a local wi-fi network.

So why do you need DSL or cable at home? Maybe you don’t. But whether you use a physical set of wires or wireless to bring a data connection into your home, the “internet” is not free. The internet requires an infrastructure which in the U.S. was in large part paid for by tax payers and built by the Ma Bell spin-offs. Some things are going to shake-down, finding a new balance between the locked-in sky-high prices and the apparently free VOIP services. Some things will likely remain the same, the traditional service providers continuing to charge the maximum amount possible until forced to reduce their prices through threat of suit or competitive market demand.

For now, you may reduce your phone bill with Vonage or Skype while adding the ability to call 60+ countries at no additional charge Smaller world. Smaller bill.

A Traditional Halloween

A Simply Evil Evening
For this year’s Halloween, I attended a gathering of ghouls at the tomb of my neighbors Pete and Daniella. The party was perfectly … horrible!

The front porch was itself a haunted house, the Jacob’s Ladder lighting the fog as it sizzled from bottom to top. Inside, The Exorcist played without sound while witches cackled, pirates said their share of “Arrrggh!” and monsters did groan. When the devil had ensnared each and every soul through food too good to pass by, one frightening fiend read an original story about this hallowed eve which included each of those present, the youngest of which, a vampire, ensnared by every word. The night concluded with a most wicked guitar duo which surely roused all in hell to dance, only to lay down again.

Before the days of dying in lines at the mall, digging graves for our debt, people told stories, ate good food, and scared each other just enough to make the walk home a little faster than that which brought them together.

Over the Sun We Shall Go!

Footsteps in the Wind
Just a few nights ago, I slept beneath the shelter of a tent in the Stanage National Forest, near Hathersage, England, and awoke to the sound of a light rain and the wind whipping the camping permit against the stretched nylon with a nearly steady rhythm, footsteps echoing down long, narrow corridors.

I held to the image and poetic composition of my dream: an old, tall, thin man, arms waving, running without apparent destination, overwhelmed by the obvious, pending doom. He wore a tattered black top hat, a long, black tail coat split at the bottom and pointed, broken shoes. His bare, white ankles shown just below the limit of his dusty trouser legs, the cuffs of his once-white shirt longer than the coat. He was bent over as he moved, compensation for his unusual height more than for pain in his back or defect in his bones.

He was, in the Hollywood tradition of pre-industrial revolution London, wide-eyed and mad, going on about things which the mass of equally ragged individuals around him generally ignored.

In this dream, I was a child who could not ignore such a man, even crazy as he was, for what he said hurt deep within me. The concept that there could be nothing new was too much to bare without challenge.

And so the exchange unfolds …

There is nothing new under the sun!

“There is nothing new under the sun!”
I once heard a man cry.
I looked across the crowd,
called to him and asked “Why?”

He stopped, considered,
and then came to my side.
“Innovation, invention, and creativity cost.
It’s an accepted principal that new ideas are lost.”

“We just recycle what is here,
to use again and again.
Something truly new?
Well, that would not be what has been.”

And with a touch of his hat,
and a brief, shameful grin,
he shook my hand
and then bounded down the street again.

“There is nothing new under the sun!
… nothing new under the sun!
… under the sun!”
his voice fading into the clamor and din.

I was moved, yes,
but impressed I was not.
The answer was clear to me,
for the sun is indeed quite hot.

But to live without risk,
that’s not living at all.
To avoid the light of the sun,
is to avoid the call.

And so I ran in the opposite direction,
with a confident, wide grin, yelling,

“Over the sun we shall go!
Over the sun we should seek,
for there the ideas are new,
and the innovations replete.”

1912-2009: From Fuel-stove to Grid-tied

This is a summary of more than ten years’ remodeling of my home in historic, Old Town Loveland, Colorado. Other stories about the work on my house include Shot in the Back and Fiddler Through the Roof. Earlier photos are forthcoming …

Do we really have to buy it?
In the fall of 1998 my parents drove up to Colorado from Phoenix, Arizona to co-sign on my house. At that time, I had never carried a credit card nor debt of any sort and therefore had no credit history. I was proud of this fact but the loan officer was just shaking his head, tapping the computer monitor screen as though the lack of data were incorrect, impossible.

My parents arrived just hours before the signing. My mother stepped from the car to the sidewalk where my then girlfriend Janet (owner of the famous Yellow Dog “Potter”) and I greeted them. My mother stopped, looked at the house, at my father, and then to me. My stomach did one of those implosions as though someone invisible punched me. I had hoped for “You did well. Good choice,” or at least, “Well, it’ll take some work, but it will be a jewel in no time.” Rather, with tears in her eyes, her lips quivering as she fought back the words, “Do, do you really have to buy it? Maybe there is another one?

[pause, looking around] Did you look in the rest of the neighborhood?” This, coming from a seasoned home remodeler was really not good. It was that bad, the worst house in the best, Old Town neighborhood.

A Tract Home of the 1900s
Built in 1913 for the sugar mill employees of Loveland, my home, like many of that day, was nothing more than a tract home. It is likely someone said of that neighborhood then what we say now, “Oh! Isn’t is just horrible! They all look exactly the same. They just, well, they just cut them out like cookies but paint them different colors. I hope they plant some trees.”

Nearly one hundred years later, the house has received two additions (once by a previous owner, as is evident in the attic by a second roof-line, and again by me). Now one must literally walk inside the houses of this area to recognize the similarities in the original floor plans.

Within 48 hours of signing, Janet, my parents, and I filled a 40 cubic yard, roll-away dumpster with the things we removed, including a make-shift closet (keep in mind that closets were not an integral part of home design at this time), kitchen cabinets and counters, and cat-piss soaked, Brady Bunch orange carpet and particle board underlayment. Disgusting.

7 Years Not at Home
The seven years that followed saw steady, but relatively slow progress as Colorado is conducive to outdoor activities nearly every weekend of the year. Given a choice, for those weeks I was not traveling for Terra Soft or for adventure, I would nine times out of ten choose rock climbing over scraping, rewiring, painting, or plumbing.

2003-1

Nonetheless, I filled a 40 cubic yard dumpster two more times, and a smaller version at least two times with the rubble of demolition and remodel. It has been a labor of love and hate as nothing can be more rewarding and completely debilitating than completely rebuilding an old house, inside and out.

2003-2

I have not by any means moved to restore this home to an historic condition, rather, I have worked to improve its function while reducing its energy footprint (long before “carbon offsets” was in the vernacular). Each project had at some level an intent to improve the insulation and thermal properties of this otherwise black hole of residential energy consumption.

2005-deck

Now, in the summer of 2009, I do contend that my home is one of the most energy efficient in the neighborhood, especially for its age and humble beginning.

From “Sow’s Ear” …
Allow me to take you through the projects, from beginning to present day. I will start with a description of the house, as it was when I acquired it in the fall of 1998:

• Original single-pane wood frame windows, most of which neither opened nor closed from whatever position they occupied. Enormous air gaps one could feel if seated on the opposite side of the room.

• No insulation in the plaster-lath / pine ship-lap walls, for it had not yet been invented when built in 1913.

• No sub-floor insulation beneath the tongue-grove fir.

• Lowest Energy Star rating possible forced air furnace (I believe the owners installed it “new” just a year or two prior to selling; looks good on paper, a joke in reality).

• 4-6″ rock wool and mouse droppings attic insulation, a seemingly 60/40 split between the two.

• No insulation between the eaves nor over the soffits.

• All original knob-n-tube wiring across the attic with splices into Romex as it came through the walls and into the breaker box. Fooled the inspector (or he just didn’t care) for the report clearly said, “All new wiring”. Fooled me too until I started crawling around in the attic a few years later, horrified at the mess.

• Chaotic, scary disarray of an attempt at plumbing.

• A guilty excuse for a traditional, tank water heater whose pilot light (when it was not put out by the leaking water) alone must have been ample energy to heat a half dozen gallons a day.

• A wood burning stove rested on several hundred pounds of sandstone which were placed on 4 inches of concrete which was poured onto a piece of 3/4″ plywood which was, believe it or not, placed on top of the Brady Bunch orange carpet and cat-piss soaked backing (I kid you not). This assembly was so heavy (and ill designed) that the north side of the house slumped four inches over a twenty foot run!

In the winter, the furnace would run nearly non-stop in an attempt to maintain just 60F degrees. At least eighty-five percent of the time on, the remaining down-time more likely due to sheer fatigue for trying so damn hard than the wall mounted thermometer giving permission to take fifteen.

At the worst of it, having grown completely fed-up with the inefficiency and filth of forced air, I removed the furnace and duct work from beneath the house only to head out on another roadtrip for Terra Soft. When I returned, I had but one heat source in the entire house which was hard pressed to maintain 48F degrees by day and a low of 36 or 38 at night. On the other end of the house, despite an electric space heater, my feet literally froze to the bathroom floor as I brushed my teeth.

A few years prior, perhaps just two or three after the house was purchased, my parents came to help me transform what was the primary entrance through a screened-in porch into a breakfast nook with the entire southern wall rebuilt in glass block.

However, after two weeks effort, the porch was demolished but the new wall was not even started, a sheet of plastic stretched and stapled across the 15′ x 7′ span … for an entire year. I recall enjoying snow flurries in my kitchen, the neighbor’s cat on my couch when I cam home at night, and more than a normal supply of mice, unwanted but not altogether horrible guests for they remind me that mammals are capable of surviving in harsh extremes.

This is not a description of my house alone, rather a typical, turn-of-the-last century home in Northern Colorado or anywhere in the Midwest where wall insulation had not yet been invented; electrical wiring, forced air, and plumbing were remodel projects done on the cheap by inexperienced home owners or friends who claim expertise demonstrated by their ownership of tools.

… to “Silk Purse”
And now for a decade of improvements, a complete make-over:

• 1998-2005: Major remodel projects such as the installation of solid oak, tongue-n-grove floors, re-plumbing the entire house, expansion of the bathroom and simultaneous reduction of the number of doorways into the kitchen, construction of a poured concrete countertop rimmed by 13 layers of 1/16″ hand-laminated oak, installation of custom built oak cabinets and five bulk food bins, construction of an exterior entrance to the basement to replace the trapdoor in the kitchen floor, and all interior walls repainted (at least once, sometimes twice).

south facing glassblock wall

• 2002: Planted 3 aspen trees on the south east corner of the house.

• 2002-03: Replaced south wall of kitchen with glass block.

• 2004: Planted three additional aspen trees and a relatively fast growing, large bush (sorry, forgot the name) to provide shade from the afternoon sun by summer, and allow direct solar gain in winter.

• 2006: Installed tankless water heater (which requires no pilot light) for on-demand, non-stop hot water. Seriously, why has all of Europe, Asia, Central and South America used these for decades and yet North America is just now considering them?

• 2006: Removed rock wool insulation from the attic.

• 2006: Removed 3 layers asphalt shingles and 1 layer wood shakes, then resurfaced entire roof with plywood, Iceshield over the soffits, felt, and 50 year shingles. Fiddler Through the Roof provides a humorous side-story about this project.

• 2006: Installed 4 double-pane, crank-open skylights which drastically cut thermal build-up during otherwise hot summer days. I have noticed a tremendous reduction in heat retention in the lower living quarters following the installation of these windows.

• 2006: Finished kitchen floor with ceramic tile to absorb heat in the winter, remain cool in the summer. (see photo of glass block, above).

• 2006-08: Replaced forced air with heating unique to each room. Installed a natural gas stove for the living and dining rooms and den. Installed 220V electric space heaters (3 total), one each in the kitchen, bathroom, and new-addition workshop. The manufacturer recommended the coil + fan model as 15% more efficient than “hydronix” which is 10-14% more efficient than traditional baseboard “cal-rod” models.

• 2006-09: Rewired entire house, top to bottom with an emphasis on electric circuit load balance, logical room organization, and ease of migration from grid-tied to inverter breaker box should the needs change.

• 2007: Installed (only to remove a year and a half later) traditional fiberglass batting between the rafters in the attic, as detailed in the story Shot in the Back.

• 2007: Sprayed Icynene expansion foam beneath the kitchen, laundry, and bath floors as well as a “rim shot” to seal the small, unfinished basement (which now keeps the pipes from freezing even without heat tape).

• 2007: Replaced all windows with double-pane, low-e glass in vinyl frames. Treat all edges of all windows, inside and out with silicon and where appropriate, new wood trim.

• 2008-09: Replaced all entry doors with exterior grade, solid fir doors.

• 2008: Blew cellulose insulation (made from 100% post-consumer, finely shredded newspaper treated with a fire-retardant chemical) into the walls, a procedure which requires drilling a few hundred holes, one high and one low between each exterior wall stud, and then applying a vacuum hose with nozzle and high pressure air to force the insulation into every nook and cranny. Incredibly effective!

• 2008-09: Replaced both front and back doors with exterior grade, solid fir doors. This fall removing a 3rd door from the west wall, to be replaced with a circular window.

framing matching siding walls and frames insulation

• 2008-09: Added 200 sq-ft addition (workshop) on west side incorporates an application of Icynene expansion foam between the 4″ stud walls and 10″ rafters for an audio, vapor, and radiant/convective barrier that is truly impressive — just 4″ foam provides the equivalent R value of 6-8″ fiberglass plus the added audio, vapor, and radiant barrier which fiberglass does not provide. The two hand-crank skylights coupled with the two double-pane, sliding windows provide for natural circulation in the summer months, a cooling tower effect which is highly effective.

See “What was learned?” below for more information.

removing old rock wool insulation adding expansion foam insulation adding cellulose insulation to attic joists

• 2009: Sprayed 4″ Icynene expansion foam insulation between all rafters in attic for an audio, vapor, and radiant/convective barrier; blew 6″ cellulose insulation between attic floor joists before the application of 3/4″, tongue-n-groove wafer board.

• 2009: Installed a ceiling fan in the living room and dining room (each) to encourage efficiency through air circulation in both summer and winter.

pv panel frame construction pv panel frame construction pv panel frame construction pv panels installation 840W solar photovoltaic array

• 2009: Completed the design, fabrication, installation, and wiring of a rooftop 840 watt solar photovoltaic array, 300Ah battery backup, and grid-tied inverter which was on September 22 approved by the City of Loveland Electric Utility as the first battery-backed, grid-tied solar photovoltaic system in the district.

What was learned?
It is far simpler, faster, and less frustrating to build a new house than remodel an old. But that is a lesson anyone who intentionally acquires an historic home already knows, and for some incurable reason repeats a few times in his or her life.

Overall, it is possible to take a relative piece of s&*! and turn it into something quite nice, even energy efficient if you put enough thought and time and yes, some money into it (but far more time than money).

In quick breakdown, consider the following:

Insulation, insulation, insulation. It is the answer to just about every home heating and cooling issue. Insulation by its very definition is a means of blocking the movement of heat from one place to another. The more energy transfer is kept in check, the less energy your home requires to maintain the inside climate as you desire. Consider blown cellulose into existing walls or Icynene expansion foam for attic eaves and new construction.

Learn from the past. Returning to the methods of the 1800s, look again at room-to-room radiant heating, individually powered or supplied by a central boiler. It just makes good physics sense. A flame more effectively heats a liquid (water) or solid (metal) than it does a gas (air) as a liquid is far more dense, the molecules in closer proximity for energy transfer. Hot water or the hot surface of a stove will transfer radiant (infrared) heat to floors, walls, furniture, even people far more effectively than trying to heat comparatively far less dense air (as with a furnace). This is why it feels so good to walk into a room heated by a wood burning stove vs a central air furnace.

Central air is not a good thing. Central air is a terrible, dirty, disgusting, bad for allergies, bad for the pocket book excuse for developers to use words like “simple” and “intelligent”, making the customer feel good about buying a home which offers the least efficient means of heating a home possible.

Do you need cooling? First consider ceiling fans, improved insulation, doors, window pane and frames, thermal window shades; passive cooling via opposing (top to bottom, East to West) windows; shade trees, an attic fan and/or a swamp cooler. And if you do already have but desire to improve your AC, consider all of the above anyway, as well as a heat pump which pre-cools / heats your central air by circulating a compressed liquid through closed-loop pipes which run 30-40′ into the ground.

Thermal containers do work! While not originally intended as an energy efficiency effort, it is now very evident that the addition of the porch-workshop (described above), which covers the entire west end of my house, does keep the house considerably cooler in the summer and warmer in the winter as it provides a thermal barrier to both extremes.

For more information about walls and rooms providing thermal containers or barriers, you may want to read-up on double envelope houses, an invention of the mid ’70s; or consider the value of wrap-around porches and how these shaded spaces provide for cooler air drawn into interior living spaces in the summer months.

Be open to experimentation. I am now heating each room (or set of rooms) nearly independent of the others, experimenting with a radiant gas stove, recessed 220V electric space heaters (radiant coil + squirrel cage fans), and soon, a south-facing solar black-box “heat dump” for the bedroom. The later, passive heating system can be built of a steel or copper clad box with river rock or water bottles inside to absorb and retain heat by day, then radiate by night. This method of heating is being implemented by the Navajo as a completely 100% renewable, no electricity required means of heating their homes.

Bouldering at Stanage, England

Not to be Taken Away, Grand Hotel Boulder

Driving in the North of England, on the narrow, winding roads is as anticipated–magical. The countryside has seemingly not changed for hundreds of years. Small villages with quaint roadside shops. Dark forests. Roads so narrow it is amazing cars are even allowed, let alone parked or passing. Fog banks rolling across the stone walled farm lands and sheep dotting the landscape as far as the eye can see.

To Be or Not to Be, Grand Hotel Boulder

Having checked the prices of B&Bs over local pubs, Fulden and I determined we could purchase a tent, sleeping bag, foam mat, and spork (spoon-fork) from a shop just across the street from The Outside Place in Hathersage for half the price of two nights in the least expensive accommodations. (Certainly subject for another blog entry is the ludicrous cost of everything in this country)

We camped at the Stanage National Forest campground, just below the Plantation. It was beautiful. Past a cattle guard, a single-lane blacktop road takes you twisting down, down along one of the countless thousands of hand built stone walls through a gate and into the open, grassy terrace of the campground. The manager was very accommodating, offering the loan of a map, books, and climbing information. Steaming hot showers are available as well.

At dawn of Saturday morning, the wind was so fierce the tent temporarily collapsed (inverted) and I had to press it back to its upright position, from the inside.

We took the trail from the campground through the forest and to the Plantation, soon climbing in what were most certainly gusts over 50MPH driving sideways mist and debris. But the temperature was tolerable due to the cloud cover, the rock remaining dry on the leeward side of the boulders. By evening, the wind died down and the sun came out. The final two hours of climbing were incredible.

Although colder, Sunday was mostly sunny and replete with what seemed to be half of England at this popular destination. Entire families on ropes, toddlers bundled up and bound at the base of the crags; eager kids in bright red helmets crawled over warm-up boulders like ants over a fallen bowl of icecream; proper boulderer without helmelts but with pads, and those who were just out for a hike along the few miles of trail that run the length of the gritstone ridge.

True to its reputation, gristone may just be the most perfect substance on the planet for climbing. It is neither too sharp nor too smooth, a contiguous surface of friction. It offers decent crimps, incredible slopers, bomber ridge lines and finger pockets that hold from all directions. It is possible to just walk up nearly vertical surfaces without so much as a grain coming loose from beneath the rubber of the climbing shoe. Amazing.

In all, an incredible adventure.

At the Door of a Decade, Part 2

Three weeks ago the Fixstars Solutions’ Colorado operation was closed.

I have been waiting for the right words to move from mind to brain, from fingers to keyboard. I believe I have been waiting for something profound, something worthy of the closure of more than a decade of my life and yet this transition was neither sudden nor unexpected and therefore, perhaps, not worthy of a great deal of commentary.

Much of the value for which Terra Soft was acquired by Fixstars was eroded by decisions made by key vendors, then compounded by market trends and weak economies. Frustrating and certainly not foreseen last fall, I feel for Fixstars’ CEO Miki-san who spearheaded the acquisition of Terra Soft in challenging times as a means of rising above the average. I am certain he will find a new, solid direction.

Director of Engineering Owen remains on-board from his location in Victoria, Canada and is working with the Tokyo-based engineers to advance Yellow Dog Enterprise Linux (YDEL) offerings.

As I am no longer involved with the Yellow Dog, I am both thankful and sad for what was, excited and uncertain for what will be.
