A few months ago Crispin Pemberton-Pigott suggested that we put together a chart of the sizes of various particles that are small enough to inhale and cause problems in the lungs. It was a great idea, and here is the result.

The $300 House challenge - to build a reasonable shelter for under $300 has announced their winners! The full grid of winners is on their site:
and a slideshow with detail pictures:

The next stage is a prototyping event, and we'll see if those pretty designs can actually be built reasonably for $300. More on the history of the challenge and on their prototyping efforts is on their blog: http://www.300house.com/

Congratulations to Ashden Award Winners Toyola Energy Ltd (Ghana) and Aga Khan Planning and Building Service (Pakistan)

Toyola Energy

Toyola Energy Finances their cookstove through an innovative credit system. They sell the stoves on credit, and provide a "money box" which proud stove owners can use to pay off the stoves from the money they save on charcoal each week. That has allowed the company to employ local producers to build the stoves, and increase the number of improved stoves distributed and in operation while at the same time cultivating pride in ownership among stoves owners.

Aga Khan Planning and Building Service

AKPBS distributes improved stoves as a part of in integrated approach that helps families owners with insulation, and improved stove with chimney, a water heater, and a roof hatch to let in light and fresh air. This cultivates a pool of locally based artisans and entrepreneurs and the integrated approach dramatically each families lives while reducing the fuel they need to burn.

Hi Stovers,

This was a great opportunity for me to break out of my two year "lurker"
role and contribute. I have quite a bit of first hand experience with goat droppings as both a TLUD fuel input and a biochar soil amendment. In late
2009 I was asked by researchers at PATH to evaluate it as a potential fuel in a possible stove project, which they were planning in northern Senegal.
Although the project did not get funded, I had very good results with this type of dung.

It, of course, has a lower density than man-made pellets. However, if you could get those goats to squeeze a bit harder (a stand in one place), it would be perfect. It burns very cleanly and smells great. I had the resulting Goat poop charcoal tested for ph, adsorption and adsorption, by Dr Hugh McLaughlin. As a soil amendment it's high ash content would give it a significant liming effect, but this was largely neutralized by rinsing.

It worked well in pot tests and I have attached Hugh's data sheets.

We have not had much of a chance to work with this in the field, not a lot of goats in Central America. However this has become a staple fuel in my High School stove building workshops. What 15 year old doesn't like to light poop on fire?

> It is a spreadsheet and a PDF with explanations and caveats. There could always be more. Testing stoves is a messy business.
So, don't read too much into any particular test, though they were chose to be representative of the technologies involved. It is expected that during the next three years we will make improvements on all of them. The ignition of the stoves involves 'technique' and as those skills are developed and transferred, we expect even better performance.

> You will see that two classes of stove, TLUD and Crossdraft, are consistently performing well no makes who makes it. I have not been making downdraft stoves for this market but will do so from July. That will bring in another strong contender into the 99% reduction class.
> It is not clearly stated that the stoves are developed for a particular fuel (lignite from Nalaikh Mine). They can be adapted to any fuel as far as I understand things. We are going to try goat dung during the coming year.
Dung burners: don't forget we are going to work out something for Central Asia!

Biochar Industries part of Biochar Project in Kunghur Australia is now selling Biochar TLUD cook stoves as part of our plan to make more people aware of the benefits of biochar.

TLUD is an acronym for Top Lit Up Draught meaning you lite it at the top and the air is sucked up through the fire. Fantastic device that is light to carry and will work with all woods great survival tool . The best feature of this Tlud is when the flames go out you then have biochar. All you have to do is drop the embers on the ground and spray some water on them so they don’t continue to burn.

This particular model was imported from India and has a very nice finish and somehow I ended up with some to sell so I wanted to let my readers know first before I start selling them at stores and markets.

Jock has updated his iCan instructions on Flickr:

from Jock's email:

The triplets of triplets in the secondary air supply is a significant improvement.

The 18-12-6 iCan now has much greater total time with a very well behaved flame and an air fuel mixture that is lean to good for most of the run.
There are still several minutes of a too rich mixture that does emit some soot.

Run time on 350 grams was 27:45, most of the smoke was gone within 2 minutes, just two floaters, and the biochar had a good clean nose. This is about as good as I have gotten so far.

The GEK Power Pallet, is everything you need to go from woody chips to electricity on a shippable pallet. It's built in California, and it's designed with the non-technical user in mind. It's designed for hands-off power generation, and the attached 2011 ALL Power Labs catalog shows schematics and details.
