Engineers Aim To Make Cleaner-Burning Cookstoves For Developing World

vinces99 writes in with news about a new cookstove design for developing countries. "About 3 billion people, or 42 percent of the world's population, rely on burning materials such as wood, animal dung or coal in stoves for cooking and heating their homes. Often these stoves are crudely designed, and poor ventilation and damp wood can create a smoky, hazardous indoor environment day after day. A recent study in The Lancet estimates that 3.5 million people die each year as a result of indoor air pollution from open fires or rudimentary stoves in their homes. More than 900,000 people die from pneumonia alone, which has been linked to indoor air pollution. University of Washington engineers hope to make a dent in these numbers by designing a cookstove that meets a stringent set of emission and efficiency standards while still being affordable and attractive to families who cook over a flame each day. The team has received a $900,000 grant from the U.S. Department of Energy to design a better cookstove, which researchers say will use half as much fuel and cut emissions by 90 percent."

      I initially assumed that the design would use natural materials - otherwise, what use could it be to anybody?

      If it were my team, I'd be looking at ways to build it from natural materials first, found materials second, and using a minimum amount of manufactured materials. Found materials could be anything, from a length of pipe, to corrugated steel, an automobile muffler, a metal grate, or even brass AK-47 shell casings. They'd have to be ubiquitously common, and really cheap or free to obtain. They might even do some field work to learn what kinds of materials fit those qualifications in poor villages around the globe.

      But building is separate from design.

      I'd want to first design and test it out of materials perfectly suited for the job. Make sure the design actually reduces emissions as required. Then, start substituting the parts for scavenged materials, and learn what impacts those choices have. Does using a rusty exhaust pipe for a smokestack emit lead? Don't use it. Does a flat rock substitute for the heat shield? Great. Does a corrugated sheet metal shroud only have half the thermal efficiency? Ok, but maybe there's a different shape that would make it better if that's the materials you think people will have available to them.

      But maybe they find that some key part is critical to reduce emissions, and it has to be manufactured. They then have to find a cheap way of producing them, while keeping them compatible with a wide range of other parts. I wonder if $900,000 will be enough.

      What do you consider "natural materials"? If you're limiting them to dirt, water, rocks, and plant material it's pretty difficult to get a good design, particularly since the plant material can't be used because it burns up. Still, as long as "dirt" isn't just sand, then water and dirt can be used to make brick, adobe, and with high enough temperatures free-form ceramics. They ought to be able to make a decent stove, complete with venting, with those materials, and the cost is labor and fuel to heat mud into bricks/adobe/ceramics. Heck, adobe is sun-dried.

    I'm sure it's not a perfect parallel but it just strikes me as hubris that you think you're going to take a community that cooks with dung on a dirt floor in an unventilated room and move them to what you're describing in one step, and criticizing people who are taking a more conservative approach as the "pat-yourself-on-the-back-for-helping" type.

    I mean you MIGHT be right that 5 minutes of Youtube research would trump this large university-led project, but it sounds like they've done at least some market research, and probably learned from more ambitious but failed experiments in the past.

    What you're saying is an attractive excuse because it puts the blame on poverty rather than the people themselves, but does it make sense? There are some investments that require money, some that require time, or both. The ones that require a time investment and yield a time savings can be done almost immediately. I don't think there are many communities on the planet where every person works at maximum capacity ALL the time. It's certainly not happening in the entire developing world simultaneously. Someone in the community has some extra time, guaranteed.

    The ones that take money can generally be accomplished by groups of people. In a community where everybody lives on $1/day, maybe the community lives on $100/day, which is $36k/year. When everybody sacrifices a penny, it makes no difference to them and accomplishes nothing, but when the community sacrifices $360/year, that's enough to make small investments.

    Then there are things like division of labor that can be applied with no investment at all and that yield huge efficiency gains right away. I'm guessing it's mostly societal norms that prevent more of these from being adopted. If you think every woman should be at home making all the meals herself on a dung-fueled stove, that is forcing inefficiency. Instead you could have a small group of people cook for the whole community, freeing up a huge amount of labor. You lose the ability to customize your meal. Big whoop. If you have a superstitious/religious problem with birth control and are unable to practice abstinence, you end up with too many kids and once again with traditional roles half your population is tied down in inefficient uses of time. When you put it that way, it sounds very narrow-minded, selfish, and self-defeating of the community rather than a noble problem of simply not having the resources to make an initial investment for thousands of years.

    To top it off, these people don't live in isolation and don't have to reinvent the path to modernity on their own. Every country in the world has population centers, wealthy people, education systems, and charities.

    I personally own a small Russian oven (I am Russian) and am repairing it just now so I must stress that it's NOT so efficient. Problem is that to collect all the smoke produced in a furnace the passages should be short enough limiting the heat collection efficiency. So the two-furnace ovens are usually built but it differs from a traditional design. The second furnace has a traditional "Holland" construction.

    And a traditional Russian oven is too big. There should be at least 1.5*2 meters sleeping place on top for all the family.

    What I said was that poverty is the cause of poverty. Being poor in the first place is the cause of staying poor. I wasn't blaming anybody for anything. I was suggesting that this cycle of poverty can be easily broken by people not stuck within the cycle.

    Somehow, I think that if you have to cook your food in your single pan over an open fire, long term concerns aren't really high on the list.

    No they aren't, which is why it is important to reduce the cost as much as possible. People barely scraping by don't have the luxury of making long term investments like education. They need to spend their time on what they know works and will keep them alive. Unfortunately what they know works is really inefficient. But if costs can be brought down low enough, then they don't need to make a long term investment. They can make a low or medium term investment with the same benefit potential.

    And it may be hard with air pollution, but once they see the benefits of higher fuel efficiency, they may be willing to take a risk now that it seems more likely to be a good investment.

    Looking at people on welfare in the US, it seems like it's not very easy to break the cycle even when you're giving people tens of thousands a year in cash, food, housing, and public education. Some people get off welfare, others are on for much of their lives just like their parents before them.

    A big chunk of people on welfare in the US are completely dependent on it. Which means that without welfare, there would be no reason for them not to be as poor as the poorest people in Africa.

    How would you explain the fact that the quality of life for people on welfare in the US is so much higher than people in Africa. People on welfare in the US have access to safe food, clean water, healthcare, mobile phones, television, etc, if not for the welfare system we have in place?

    The quality of life in the US is also better now for the average poor person than it was a hundred years ago. We still have poor people but these people are poor relative to other Americans. As long as people have unequal wealth regardless of how much or how little everyone has, there will be poor people relative to rich people.

    We will never reach a state were 100% of people are off welfare. If anything, as our society gets more wealthy, we will probably continue to raise the threshold for what we consider poor. The fact that the same number of people are on welfare is not an indicator that it is not working.
