Bio Fuels

BioFuels are made from plants or manure, and have the potential to reduce greenhouse gas emissions, as well as reducing the dependence on imported oil and all the turmoil that seems to come with the imports.

Hybrid Masonry Stove



"we used a style common in Germany, the hybrid masonry stove. It uses a steel or cast iron stove for the firebox but wraps masonry around the metal on 4 or 5 sides, excluding the loading door and, optionally, a cook-top. We added a large masonry chamber behind the stove to allow flue gases to circulate through some extra mass, boosting the total masonry weight to 2 tons."
Masonry Heaters from Gimmie Shelter

Heating Water With a Wood Stove



This excellent article on domestic water heating with a wood stove provides descriptions of several good systems, and covers the features a good system should have.

It also provides safety information which is MANDATORY READING for anyone adding water heating to a wood stove.
Preheating water with a Wood Stove


A similar arrangement from Mother Earth News:


A design for a system to preheat water with your wood stove that does not require major surgery on the wood stove.

Be sure to read the material on safety in the article above -- especially on placement of valves and pressure relief.
Outdoor Wood Furnaces ...


Outdoor Wood Furnaces burn wood in a furnace located in a separate enclosure away from the house.  They heat water, which is piped to the house for space heating.

Its an appealing concept, but unfortunately the current generation of these furnaces are half as efficient and 20 times more polluting than certified indoor woodstoves.

There is some effort underway to offer cleaner versions.  So, if you are interested in one these, do your homework on certified versions, and think about impacts on your neighbors.
BioMass Cooking Stoves



"This site exists to help people develop better stoves for cooking with biomass fuels in developing regions"

Especially good section on efficient stove design.

Woodstoves for Tub Heating (or for heating thermal storage tank?)

Chofu: supplier (one of many): Earth News article:
 describing the Chofu

Snorkel and Scuba Underwater Woodstoves:


Chofu: This is a simple, wood fired heater for soaking tubs. 
It uses a simple thermosyphon system to circulate heated water (no pumps, no electricity).  The full stainless steel case is a water jacket for efficient heat transfer.

Snorkel & Scuba: These wood stoves for heating tubs actually live in the tub water, so heat transfer is directly from the stove walls to the water.

It seems like this might be a simple, and greenhouse gas friendly  way to add heat to a solar heat storage tank when there is not enough sun?

Journey To Forever on Jean Pain:

A good two part video showing details of a large compost to heat and biogas pile and more:  (part 1) (part 2)


The book covers Jean Pain's  research in using compost for both agricultural and energy production.  There is some good, practical information on building large compost piles for the production of heat for water or space heating. 
One example 50 ton pile provided the equivalent of 200 MBTU over a 6 month period -- enough to heat a house.

Picture from the video -- finely shredded wood with plastic pipe to capture heat and fermentation vessel in middle to make biogas.

(Thanks to Curbie for finding the video!)

Heat free (nearly) with a compost furnace


This is a very nicely thought out space heating scheme that uses a large compost pile to generate heat.

Marc has worked out a design that provides for aerating the pile, keeping it moist, collecting the heat, and insulating the pile for greater efficiency.

More from Marc and his results for the first year of operation...

This is an interesting set of concepts that use the heat generated through the decomposition of organic mater for space and water heating.


Composting Greenhouse with Straw Bale Foundation, From Experiments in Sustainable Urban Living ...


This uses surplus heat from a large compost pile under the greenhouse floor to heat water for the house.  You get water heating and greenhouse space with the same structure!

This is a pretty slick idea for heating water with heat generated from compost, as well as providing greenhouse space.
The thing that intrigues me is that you can apparently have working greenhouse space above the heat generating compost pile? 

I'd like to hear from anyone with composting experience on how workable this all seems? Gary
