Project Summary
Elevator Pitch

Concise Summary: Help us pitch this solution! Provide an explanation within 3-4 short sentences.

The current supply of biomass energy in Kenya is unsustainable. We are utilizing the waste from sugar industries in Kenya to provide clean, affordable, fast and eco-friendly cooking energy through biomass gasification technology.

WHAT IF - Inspiration: Write one sentence that describes a way that your project dares to ask, "WHAT IF?"

What if the world's population knew about biomass gasification technology?
About Project

Problem: What problem is this project trying to address?

Millions of families in Kenya depend on biomass for their daily energy needs. This results to depletion of the forest cover and health complications, among other negative effects. About 15,000 people die in Kenya every year due to indoor air pollution. More than 50% of premature deaths among children 5 years and below are due to pneumonia caused by particulate matter (soot) inhaled from household air pollution.

Solution: What is the proposed solution? Please be specific!

Wood gasification stoves are one of the leading solutions for indoor air pollution. They convert the harmful greenhouse gases including CO into cooking gas, therefore eliminating indoor air pollution. However the available options are too expensive and difficult to adopt. Most of these models can only use pellets which are not available in the Kenyan market. They also require power to operate which is not available in most rural and peri-urban households. Wisdom stove is the most affordable gasification stove in the Kenyan market. It generates its own draft therefore it doesn't require power to run the fan. In addition to burning pellets, this stove is customized to use any type of dry biomass that the beneficiaries are accustomed to.

Impact: How does it Work

Example: Walk us through a specific example(s) of how this solution makes a difference; include its primary activities.

Our journey began when we believed that a technology can be moved from the lab to countless homes where it is needed. We have been engaging women as the key users of the heating energy in an effort to convert the features of our innovation to benefits for them. Clean emissions, fast coking and affordability are the three key benefits offered by our innovation. Women don't have to continue burying their young children they love due to pneumonia. Households don't have to spend the little money they have to buy high priced charcoal whose sources are being depleted every day. Wisdom Innovations believes in sustainability as a prerequisite for real development. We manufacture and distribute affordable biomass gasification cookstoves.

Impact: What is the impact of the work to date? Also describe the projected future impact for the coming years.

We have manufactured and distributed clean cookstoves to 2,000 households, impacting 12,000 beneficiaries. All users are trained by our sales team on the benefits of biomass gasification technology. The stoves have also opened up opportunities for pellets and uncarbonized briquettes production in Kenya, therefore creating many indirect employment opportunities. According to a compiled data from ERC (Energy Regulatory Commission of Kenya), and stove test results from University of Nairobi, total savings from the use of the stoves is estimated at $80,000. More than 12,000 trees have also been saved to date. By the end of 2016, we want to double this impact given the fact that we have obtained significant support from Global Alliance for Clean Cookstoves, a UN Foundation spearheading the clean cookstoves agenda globally.

Spread Strategies: Moving forward, what are the main strategies for scaling impact?

This idea can be replicated in almost any part of the developing world. The availability of different types of biomass waste in different regions of the world is a main reason why it is possible to scale the idea widely. Wisdom stoves also have great potential to create downstream value chains through further use of bio-char in agriculture, sanitation and water filtration. Thus they can not only be used in climate change mitigation as a tool for carbon-negative cooking but also play a pivotal role at the increasingly important nexus of water, energy and food security.

Financial Sustainability Plan: What is this solution’s plan to ensure financial sustainability?

This being a for profit company, revenue generated through sales of our stoves is the main source of income. Any support received in terms of funding is utilized to create a strong business model that will ensure sustainability of the initiative. We believe that this market based approach is going to guarantee increasing growth.

Marketplace: Who else is addressing the problem outlined here? How does the proposed project differ from these approaches?

Envirofit, burn manufacturing, ecozoom and philips have been providing clean cookstoves solutions to the Kenyan market. Our product differs from what they are offering, being the only natural draft gasifier stove in the market. Our stove is priced lowest compared to the others because all materials used in production are sourced locally.

Founding Story

Nathan Puffer who is the co-founder of the company came over to Kenya in 1984 and was concerned by how smoke from traditional cooking was affecting women and children. He researched and constructed a stove prototype that he thought could be the solution to indoor air pollution. A pilot project followed which informed further adjustments to the design. A new design was finally developed which was more effective and acceptable in the market.
