I thought I was going to get some ‘real’ work done today, but alas I came across yet another awesome story and knew I had to write a post about it.
It all started when I found this article on the Sci Fi Tech Blog. As I learned, the Digestive Table is much more than just a kitchen table - it’s a vermicomposting bin…and it’s a masterpiece! As soon as I started reading I decided I had to find out who was responsible for such a creation.
Luckily there was a link at the end of the article that took me to Amy Youngs’ Digestive Table page.
So who exactly is Amy Youngs?
Amy M. Youngs creates mixed-media, interactive sculptures and digital media works, that explore the complex relationship between technology and our changing concept of nature and self. She has exhibited her works nationally and internationally at venues such as Springfield Museum of Art (Springfield, OH), Pace Digital Gallery (New York, NY), the Biennale of Electronic Arts (Perth, Australia), John Michael Kohler Arts Center (Sheboygan, Wisconsin), Circulo de Bellas Artes (Madrid, Spain), the Visual Arts Museum (New York, NY) the Art Institute of Chicago’s Betty Rymer Gallery, Vedanta Gallery, (Chicago, IL), the San Francisco Public Library, Blasthaus, (San Francisco, CA) and Works (San Jose, CA).
Wow - this was getting more interesting by the minute!
According to her bio, Amy is now an Assistant Professor in the Department of Art at The Ohio State University.
Interestingly enough, the inspiration for the Digestive Table came from her interactions with OSU researchers Dr. Clive Edwards and Dr. Norman Arancon (both heros/aquaintances of mine), who are well-known in vermicomposting circles for their fascinating academic research in this field.
Here is a blurb from the Digestive Table page:
A living ecosystem of worms, sowbugs and bacteria are invited to this table. They are a part of the digestive system that starts with a person discarding food leftovers and shredded paper into the portal at the top. The bacteria and sowbugs begin breaking down the waste and the worms soon join in to further digest it into a rich compost that sprinkles out of the bottom of the fabric bag that hangs beneath the table. This compost is used as a fertilizer for plants, such as those at the base of the table.
The human plays an important part at the table by eating, feeding the food waste to the worms, feeding the resulting fertilizer to the plants, or by simply sitting and appreciating the living ecosystem she/he is a part of. A cross-section of the activity inside the top 9 inches of the compost is made visible using an infrared security camera connected to an LCD screen built into the table. On the screen, viewers can see the live movements of the worms and sowbugs inside.
You absolutely need to check out Amy Youngs’ website for yourself though. Not only does she provide technical specifications for those interested in building the table themselvses, but she also showcases a wide selection of incredible interesting pieces of artwork.

I felt pretty excited as I read through an article in the Cambridge Times today. I learned that there is a new green building being contructed in Cambridge Ontario, about 1/2 hour away from where I currently live.
The new civic administration building, which is expected to open sometime next year, is guaranteed a LEED Silver rating, but even may have a shot at achieving a Gold.
Some of the cool features include:
- Indoor ‘green wall’
- 3rd Floor green roof
- Onsite greywater recycling
Here are a couple of interesting blurbs from the article:
As part of the new atrium, a four-storey green wall is being installed, which is made up of plants that will filter the building’s air, improve air quality, reduce the need for air conditioning and help eliminate humidity.
…
The building’s green wall is the most visible feature of the city’s conservation effort. It will also have a 10,000-litre cistern which will collect rainwater from the roof and use it as part of a gray-water recycling system to flush toilets, etc. The third floor of the building will have a green roof - the first on a city-owned building - which will help cool the structure in the summer and retain heat in the winter.
“When this roof is in place, the roof surface will get no hotter than 75 F; temperatures on roofs that don’t have a green roof can up well over 120 F,” said city architectural design technologist Slobodanka Lekic. “I’d like to put make the entire roof green, but this is a good start.”
At Cambridge Place, city staff currently use about 65,000 square feet of space. The new facility will have 85,000 square feet of space and will be able to accommodate the addition of another 50 staff members over the next 20 years.
“This building has been designed with the future in mind,” Paul said. “It has a lot of flexibility built into it. How the building and the civic square in front of it is programmed will be the key to its success.”
Sounds great to me. I can wait to take a tour once construction is complete!

Today was garbage day so I figured it would be a good opportunity to add my growing indoor collection of organic waste to the bin while I was out.
I’m certainly glad I did! As I opened it up I could feel that the lid was quite warm. The first things I noticed inside were that the level of the material had gone down a fair bit and the plastic bags at the top were totally dry (normally have pools of water).
Uh Oh…
As I started raking through the upper layer of leaves I was greeted by bursts of steam and what looked to be hot, dry conditions. Needless to say I was quite concerned about the health (or lack thereof) of the red worms. Temperature readings were up over 40 degrees Celsius (104 F) throughout most of the bin, and there were a number of spots in the 50 C + range (122 F +).
I found a few worms up in the old rotting door mat that was sitting at the top of the composting mass, but other than that it looked like a serious red worm disaster.
Well, long story short, after digging down deeper, and around the edges I was able to find a lot of worms. I get the feeling most of them were able to escape to various cooler regions of the bin. Phew!!
In an effort to cool things off somewhat I continued to rake through the material, releasing steam and letting cooler outdoor air in (actually quite mild today). I also added some cold water via a watering can and have left the bin lid open. I will go back and check on things this afternoon.
In all honesty I NEVER expected to have an overheating problem! While it’s certainly a good sign that I have a fighting chance with this winter composting experiment, it’s also an important reminder of the fact that I still need to maintain balance.
That being said, something dawned on me today which kinda made me chuckle to myself. I’ve talked before about the tendency of city folk to let nature know who is boss - frequently cutting the grass, keeping properties perfectly manicured, killing “pests” etc. Well here I am trying to control natural processes myself! Insulating the bin, discouraging mice from nesting inside, and trying to make sure temperatures and conditions for my worm herd are ‘just right’!
Oh well, guess it’s just the ‘nature of the beast’!

It looks like the automakers are finally taking notice of the environment and are rolling out new eco-friendly concept cars powered by alternative fuels.
Some of the major players in the auto industry, General Motors Corp., Ford Motor Co. and BMW AG are set to unveil vehicles that run on hydrogen. DaimlerChrysler AG and Volkswagen AG, will show vehicles powered by E85 ethanol, electric-gas hybrid engines, biodiesel, natural gas and low-sulfur diesel fuel.
I am quite happy to see the automakers are starting to think more about alternative fuel cars but like many other customers, I am disappointed in so many ways. Why aren’t there more green cars available in the showroom? I think there is a real opportunity for independent automakers to steal market share. The old marketing model of “first-in” often times results in successful sales and a long life cycle. If the major auto makers are dragging their heels and slow to the green game, consumers will begin to look elsewhere.

I found an interesting article this evening about Paris’s plan for a new commercial building it its historic centre. The new 300 metre building, dubbed the “Phare” or lighthouse, will become the tallest Parisian commercial building since the Eiffel Tower.
The new building will be constructed with a gently sloping eco-friendly glass and will have wind-turbines on its roof. The architect selected for the project is Californian Thom Mayne.
A blurb from the article:
Mayne said he wanted the Phare to be “a prototype for a green building,” with the wind farm generating energy for the tower’s heating and cooling for five months of the year and a movable “double skin” cutting the heat from direct sunlight through the windows.
At a cost of 900 million euros (US$1.2 billion), the building, which will offer 130,000 square metres of office space, is due to be completed in 2012

I just came across an interesting headline. You may remember our “algae + CO2 = biofuel” article from a little while back. Well it sounds as though progress in the field may be a little further ahead than I previously believed.
According to the news release, De Beers Fuel Ltd in South Africa (no connection with the diamond giant) hopes to be producing 16 to 24 billion litres of biodiesel per year from algae within five years!
Here is an exerpt from the article:
De Beers Fuel already runs a plant which produces 144 000 litres of bio-diesel daily from sunflower seed oil, at Naboomspruit in the northern Limpopo province. A bio-diesel algae reactor installed at the plant will be showcased to investors, experts and the media later this week.
“The project is highly capital-intensive. The first 100 acres will require about R3.5bn, this has been sourced mainly from foreign private equity groups,” Hendy Schoombee, a senior official at De Beers Fuel said.
“We had initially intended to list the company to raise the money. We might list at a future date to raise money for further expansion,” he said.
One acre of algae can produce 92 000 litres of bio-diesel, compared to 350 litres produced from one acre of a sun-flower seed farm, he added.
The company will use land that is not arable or useful for most other purposes, and will also generate electricity from waste material out of the bio-diesel-making process.
I tried to track down more info about De Beers and came across Infinity Biodiesel, which seems in fact to be the main De Beers Fuel website. Unfortunately there is no mention of their plans for making biodiesel from algae.
Hmmmm…
Well I’m definitely interested to learn more. Just this quote alone says it all: “One acre of algae can produce 92 000 litres of bio-diesel, compared to 350 litres produced from one acre of a sun-flower seed farm, he added.”
Anyway, if anyone knows more about this be sure to let us know.
Here is a link to the story I came across: Firm to make biofuel from algae
THIS JUST IN - I found another interesting news release which goes into a little more detail. Check it out here
Here is a blurb:
Mr. de Beer has made great strides to acquire the latest Algae Production Technology. In recent weeks there have been many media articles about the success of the algae bioreactor operating at MIT (see http://web.mit.edu/erc/spotlights/alg-all.html) utilizing the MIT CO2 exhaust boiler emissions as feed for the algae.
Algae consumes CO2, a major Global Warming Gas. After consumption of the CO2, the algae produces oil (for biodiesel manufacturing) and oxygen. Therefore, the process of using algae creates renewable, sustainable biofuel and reduces global warming gases to better the environment.
Mr. de Beer has entered into an agreement with Greenfuel Technologies Corporation, (see www.greenfuelonline.com) and has purchased and removed the MIT bioreactor from Cambridge, Massachusetts, and transported it to South Africa. It has been reassembled on the biodiesel plant site in Naboomspruit, South Africa, and is now awaiting the arrival of the algae to be inoculated to start production. At the Naboomspruit site construction will soon be underway at the rail spur for a crushing plant to process oil from the planting of sunflowers throughout the region. Mr. de Beer also supports, along with the development of the algae growth technology, the local farming industry that will benefit with the planting of thousands of acres of sunflowers and other feedstocks for oils to be processed into biodiesel fuel.
