Farm Scale Study: Summary of 2010 Results

July 19, 2011

Last year was a bad year for our Energy Farm yields. The summer began with flooding and ended with drought.

Rainfall recorded at the experiment site between May and November, 2010, relative to long term average rainfall for the county.

BioChar Stove How To: Become a Pyroneer

July 7, 2011

This is a cross post from my Personal Blog where I  detail my work in South Central Wisconsin and its focus on sustainability, appropriate technology and small scale agriculture as we seek to reskill and transition to a less energy dependent future.  

Rob's Quick & Dirty TLUD Stove. $50 and one hour of fab time. About 20-30# of char per firing, 2-3 hour burn time.

I garden for many reasons, but mostly to Be the Change I wish to see in the world.  And the more I read about our need to relocalize, the more I hear about how screwed up our climate is getting, the more I read about how very real the pressures of Peak Energy are going to be, the more convinced I am that Bio-Char is an absolutely critical component in any transitional farming system.  The hard truths of our age are that we have far too many mouths to feed, we have far too much carbon in the air, our soils are denuded to all hell, and we will need local means to produce energy cause the cheap, easy stuff is gone.  Guess what – biochar can help ALL of these.  By growing coppice biomass plantations as windbreaks around CSA farm plots or in unused/unusable portions of our farms we can tap into fast growing plant’s abilities to pull carbon from the air and “fix” it into biomass.  This biomass can then be turned into biochar, which reduces syck amounts of heat that can be captured for use in myriad ways from making maple syrup and canning tomatoes, to methane and ethanol.  Best of all, the resulting char can be run through a composting regime, charged with nutrients and micro-organisms, and added to the soil for simply incredible results that increase fertility over millenia – your yeilds go up and and your farming goes regernerative as you sequester the airborne C02 in the soil.  Congrats – your farm is now Carbon NEGATIVE.

The One Straw Energy Farm: Virtual Tour

July 5, 2011

Rob Frost maintains the One Straw blog, where he reports on practical efforts to find “personal solutions to the Big Problems of today.” He is establishing an Energy Farm on 20 acres in South Central Wisconsin. Rob laid out his vision for the farm in his Making an Energy Farm post in April. Last week he offered a virtual farm tour, cross-posted here with permission.

Would like to spend some time fleshing out some more of my thoughts on my Energy Farm project.  First off, thanks to a great shot that the owners, Mike and Ellen, where able to take from a small plane (the farm is next to our community airport and they had an open house with plane rides for $25) I can better show the current State of Affairs.   The farm is located within the city limits (though only just) of a town of about 20,000 people and is located on the edge of an industrial area – indeed it is currently zoned industrial and would have potentially become a factory had the owners not saved it from sprawl.  The home has not been lived in by humans for over 15 years – though several generations of racoons have been raised there apparently…  The barn is in fairly good shape, though the roof and foundation need some TLC which is being applied in spades by Mike.

A description of our farm

July 5, 2011
Chris Saenz maintains the Woodgas Wiki and experiments with energy-efficient technology and small scale renewable energy production on his family’s land in the Kentucky hills. Here, he introduces himself and the land [ed].

 

This started out as an email to a friend. I thought with some work it could be blog-worthy.

We own about 30 acres in the hills of Kentucky. The land is not gently rolling hills, like most of the state. We have Appalachian style hollows and high ridges. Our own hollow has about 10 houses. Only a few locals are left, the rest have moved in from the “outside”; mostly folks from California and Florida who cashed in.To get to our house, you follow a narrow paved road up the creek, which gets narrower and less paved as you go. We are at the head of the valley, where it meets another hollow coming in from the east, in a sort of L shape. And so the road takes a right turn by our house, and goes on up the other hollow. The house is set up on a hill. It is a large white Amish built house, with two floors above a walkout basement, and a deep porch in the front.

Beyond Food Miles

March 9, 2011

Article released today
by the Post Carbon Institute

“There is nothing as deceptive as an obvious fact”
-Sherlock Holmes

A locavore is “a person who endeavors to eat only locally produced food” [1]. What better diet could there be for an energy constrained world? After all, feeding Americans accounts for about 15% of US energy use [2], and the average food item travels more than 5,000 miles from farm to fork [3]. It seems obvious that eating locally will go a long way to reducing food system energy use.

Yet cracking the case of America’s energy-intensive food system demands that we look beyond the obvious. A local diet can reduce energy use somewhat, but there are even more effective ways to tackle the problem. Single-minded pursuit of local food, without consideration of the bigger picture, can actually make things worse from an energy perspective [4].

Energy and Vertical Farms

December 2, 2010

Vertical farming is hot.

The idea that we should grow food under highly-controlled conditions in urban high-rises is getting plenty of media attention, along with pleas for public and private investment. A new vertical farming book by retired Columbia professor Dickson Despommier came out in October, and Sting bought the movie rights.

Vertical farm promoters claim these buildings will solve every problem from farmland shortages to population growth. They seem particularly fond of futuristic renderings of glassy skyscrapers alive with plants bathed in electric light. The grow lights are necessary because most crops would fail under the meager ration of sunlight that could filter into the depths of a skyscraper.

Vertical farm concept by United Future digital design and marketing agency.

Proponents of vertical farming commonly say it will save energy by eliminating the need for tractors, plows, and shipping. Some even think that vertical farms can incorporate enough solar panels, wind turbines, and methane generators to be net energy producers. For the most part, vertical farms are more vision than reality, but a few real-life examples are appearing, offering opportunities for critical evaluation of proponents’ claims. In this post I examine one such example from a farm energy perspective.

From Growth to Decline: Vehicle Miles Traveled in Kentucky and the USA

May 27, 2010

In a previous post I contrasted Kentucky’s energy plan with Ireland’s. Both plan to grow biomass to offset some of their fossil fuel use, but Ireland consumes far less fossil fuel than Kentucky, so can offset a much larger proportion of its energy use with each bale of switchgrass. Ireland is planning to further reduce its energy use, while Kentucky is planning for growth. My analysis of traffic volume trends leads me to believe that Kentucky’s transportation growth forecasts will not materialize.
