WorldStove Corporation. . . a million stoves to help save the worldThe LuciaStoveA New Technology and Marketing Approach for theProduction of a Combined Pyrolysis-GasificationCookstove and Related Scaled-Up TechnologiesETHOS Conference, North Western University WA2009© 2008 WorldStove, Inc

For the past 148 years peoplehave been inventing and patentingever better stoves© 2008 WorldStove, Inc

Why have we yet to see millions ofstoves?• Is it demand?• No, 1.6 billion people still cook on openfires• Do current designs not work?• No, many designs work very well• Is it cost?• No, while there are some cost $2,000 or$300 many range from $140 to $25 or less© 2008 WorldStove, Inc

Why have we yet to see millions ofstoves?• Difficulty with adoption of new cookingtechniques• Unreliable distribution networks in keyareas• Creating the “right” stove that adapts toconsumers’ needs and desires• Inability to produce enough stoves, inenough variety to create a true marketplace for consumers© 2008 WorldStove, Inc

Key Issues• One of the problems that stovers face is tocreate safe, quality stoves at a very lowcost so that they are available for themillions of people that need them.• Many designs are needed.• How can we maintain the diversity ofquality stove designs and innovationswhile still striving to meet the greaterneed?© 2008 WorldStove, Inc

Importance of Stover Community• Protecting diversity of ideas andinnovations• Ensuring that many designs areindustrialized for mass manufacturing sothat people in need have product choice• Continue to support new ideas and newstovers even as field grows to scale© 2008 WorldStove, Inc

The Industrial Mass ManufacturingApproach© 2008 WorldStove, Inc

What is Industrialized Mass Manufacturing?• 1000 stoves a year you are working• 5000 stoves a year your are working well• 10000 stoves per year you’ve got help andneither one of you is sleeping anymore• 50000 a year you’re working your tail offand have a great deal of help• All or none of the above can be donethrough industrialized mass manufacturing© 2008 WorldStove, Inc

Definition• Industrialized Mass Production: Designsthat are specifically for the production of alarge number of identical units at a lowercost.• Any item, any stove can be studied andmodified for industrialization.• However, we are not suggesting all shouldbe.© 2008 WorldStove, Inc

Adaptable to local or mosteconomical technology© 2008 WorldStove, Inc

The end result is a stove that is:• Adaptable to user habits, needs, wishes, cooking habits,available fuel• Low cost to make and ship (ships flat)• Life tested to last ten years• EU emissions certified (66 ppm CO)• Consumable parts are replaceable• Can function either as a coaxial gasifire or a pyrolyticstove• Adaptable to almost any type of fan or even used without• Creates local workforce opportunities and earnings• And at the end of its life is recyclable© 2008 WorldStove, Inc

What does this mean for stovers?Industrialization can be:• Expensive• RiskyBUT• Provides new development opportunities• New geometry options• Consumers become innovators© 2008 WorldStove, Inc
