Great Designs in Wood (13)

Image
You may recall the Maypole Inn story that we covered in GDiW(10). There's another great story of wood construction in England that occurred at roughly the same time, and on a much larger scale.


Westminster Hall is the oldest building on England's Parliamentary estate. In and around the Hall, grew up the major institutions of the British state: Parliament, the law courts and various government offices. But it's history is richer than just a gathering place for Britain's political elites. For instance, the Hall was used as an early modern shopping center, and as a drilling station for troops during 1859-1861 as Britons awaited invasion from the French of Napolean III. In 1833, Charles Dickens, having for the first time seen one of his stories in print, walked around Westminster Hall for half an hour with his eyes "dimmed with joy".


And as he looked up, he would have been gazing at the largest medieval timber roof in northern Europe. 



Memorial Day with Wood

Image
My oldest son Charlie is headed back to the Army today. He graduated from Army Medic school in Texas two weeks ago, and he spent the last two weeks here at home catching up with his family and friends. It was nice to have him home again, even for the short time. The timing of his leaving, on Memorial Day weekend, and the day after eight more troops were killed in a blast in southern Afghanistan, caused me to reflect a little more than usual on the challenge he and his fellow soldiers are facing.

Talking Wood Production at Fine Woodworking.com

Through this amazing world of online publishing, we can share blog content with others in our area of interest. Fine Woodworking.com recently ran a two-part blog post by Patrick Kennedy of Superior Woodcraft who asked me several questions relative to challenges facing today's woodworking shops.

You can view the blog postings at the links below:

Should be a "Nittany Lion" and I work at Penn State, not Penn. But Patrick asks some interesting questions that others of you in the industry may also be struggling with. I'll try to interview Mr. Kennedy for a future post on Go Wood in the near future.

Wood Biomass and Carbon Neutrality

Image
For those of you who learned about the carbon cycle back in high school or college, you probably knew that the harvesting and use of wood is fundamentally a carbon-neutral process. Or you thought you knew that, until the concept of using biomass for energy became a topic of heated debate.

Now, we have claims both for and against the carbon-neutrality of wood energy almost daily in the news. There are stories like these, that make woody biomass out to be as bad or worse than fossil fuels:

WPIF: Use of biomass will increase carbon emissions, not reduce themBiomass boiler proposal slammed by University of Montana plant employeesMA Proposes GHG Restrictions on Biomass Power
And on the other side, whenever a biomass project is moving forward, the sponsors always claim the carbon reduction benefits of using wood versus fossils fuels. Confused?

Great Designs in Wood (12)

This fascinating structure really exhibits an aspect of wood not usually featured; that is, the architectural interest of the wood components as a system. Usually, wood homes and buildings feature the natural beauty of the wood components in prominent places, while allowing other physical elements of the design to "accessorize" the building, in the process delegating the structural design a less prominent visual role. This home allows you to appreciate the beauty of the wood while you marvel at the structural flexibility and integrity of wood design potential.


From FancyCribs.com we get an introduction to the home:
"The Guscott Kemp Residence has been designed by Scott M. Kemp Architect, it represents a new approach to sustainable home construction, and is located in Ladner, British Columbia, Canada.The concept idea was to create a house as a simple shelter based on sustainable features, and to be designed as small as possible in order to allow for maximum flexibility, …

WoodPro loses the IT Wars

Image
I've been on the front line of the IT (Information Technology) wars for a long time now. Back in the 80's I was researching AI (Artificial Intelligence) under the legendary Wood Operations professor Joseph G. Massey, who, based on his life experiences with information technology research, has retired and done his best to go entirely off the grid. Lives out of an Airstream and surfaces occasionally with brief emails letting me know his remote location in the wilds of Alaska, or the deserts of Arizona, or wherever. He knows something we don't.

I took that background under Joe into industry and immediately found that the IT powers in corporate America like to call the shots when it comes to employee communication. My first conflict was in pushing the radical concept of using PC's to monitor manufacturing processes and communicate that information to others in the company. The operations and marketing guys loved the idea, but the IT folks claimed network security risks and…

The Future of Energy

Image
Penn State has a rich history of energy research and development. The School of Mines was established in 1896 and energy has been a cornerstone of the academic program at Penn State ever since. Pennsylvania has been at the center of the energy industry, from the first commercial oil well in the country at Titusville, PA, to today's unfathomly large natural gas phenomenon, the Marcellus Shale. I mention this just as a backdrop for  the excellent video I'm posting today, a replay of the WPSU show, To the Best of My Knowledge, hosted by Penn State President Graham Spanier.

This show was entitled "The Future of Energy", and aired a little over two years ago. The guests were Dr. Amy Glasmeier and Dr. Tom Richard, both of Penn State. They addressed both technology and policy issues, and answered a bunch of diverse and interesting questions. Dr. Spanier himself asked some very insightful and relevant questions.

Go Wood followers may note that in answering a question on wood…

The imposing edifice you see here is the Sakyamuni Pagoda of Fogong Temple in Ying CountyShanxi province, China. It was brought to my attention by a visiting scholar working here in my lab at Penn State, Mr. Jianwei Ren, who is a native of Shanxi province.


This impressive pagoda was built back in the year 1056, or 40 years before the First Crusades were begun. That's a long time ago. And besides its stunning beauty and amazing longevity, it has another claim to fame that should be celebrated here at Go Wood...it is the tallest existing wooden structure in the world! At over 67 meters, it would be nearly 20 meters taller than that 9-story wooden apartment building that was built recently in London. The closest wooden buildings that I can find in height are some WWII blimp hangars out on the West Coast...I'll blog about them in the future; they are also amazing in their own way.

The Bumpy Road to Biomass

Not a pun directed at our last posting, but a reference to a fine article posted yesterday at RenewableEnergyWorld.com.

Biomass Energy - Mixed Signals Abound

The author, Eric Kingsley of Innovative Natural Resources, LLC, gives us a detailed perspective of the economic hurdles real biomass projects are facing on the ground. And after covering the difficulty facing the biomass power generation, he makes an excellent observation we've made several times in many different ways here at Go Wood:
"Of course, biomass electric isn’t the only use of wood for energy.  Biomass thermal – heating homes and buildings – remains a largely untapped opportunity in a region with heavy dependence on oil for heating."This is a theme that we will all have to carry around on our collective sleeves, if we want to see biomass make a real and long-term impact on the nation's energy supply. For as many other ways that biomass can be converted to energy, it is still in heating that biomass is mos…

Warning, do not attempt this at home...

My friend John Krier tipped me off to the dedication (is that the right word?) exhibited by Russian log truck drivers, and the brute power of their vehicles. Can't say I'd like to ride along with them...

Watch for the guy in the third video to climb out of the cab and tweak the engine in mid-river with his front wheels in the air...no sweat!

Flash Update: From Bruce Shields in Wolcott, Vermont: "The logger in the 3d video is not "tweaking the engine."  He is hoping to transfer enough weight onto the bumper to pull the front end back down.  We have these things in Vermont also."

Warning: You may want to turn down your speakers a little, unless your boss is really into Russian ballads...







To timberdude in Alaska, who mentioned that his customers are always complaining about the price of lumber: you may want to show them these videos!

Following in Europe's Footsteps (2)

Image
A couple of weeks ago we discussed following too closely in the EU's footsteps with regard to energy policy. That conversation addressed power generation policy for the most part. I thought you might be interested in another facet of the same problem relative to biofuel production, that appeared in a couple of European articles during the past week.

First was an article entitled "Growing pressure to change EU biofuel policy" from EuropeanVoice.com. It begins...
"Powering cars with plants once seemed like an unstoppable idea. Biofuel was sold as a way to reduce Europe's oil dependency on autocratic regimes, meet climate-change targets and help Europe's struggling farmers. But since the European Union agreed laws to promote biofuel, doubts have sprouted like weeds. Now it looks increasingly likely that the EU will have to rewrite bioenergy laws to guard against their unintended consequences.  The problem that early biofuel enthusiasts did not anticipate was that…

Wood Science 101 - Cellulose

Image
I've been meaning to start a feature for a while now that addresses some of the simplest, but most common questions I get from the general public. No discourses on topics like self-organizing microtubule networks or the cell wall structure of wood. I rarely get questions on those topics, and when I do, I usually back away slowly.

The recent May Day weekend reminded me of one of my favorite wooden structures...one that I've never actually seen. But it's clear as a bell in my mind's eye...
