I wasn't quite sure where to post this but it seems like it would be of interest to others here. The DOE EERE is spending $2.5 million in hopes of developing low cost, efficient, less polluting cook stoves that use biomass for fuel. link: https://eere-exchange.energy.gov/#e2592fd4-d021-4123-a0f0-cd4ccae9939e The goal of this solicitation is to increase the viability and deployment of renewable energy technologies through research, development, and tools that lead to clean and efficient biomass cookstoves. This solicitation seeks to develop cookstove technologies that: · Are low-cost and affordable in regions that currently rely predominantly on biomass fuels for household energy; · Are durable and safe, address the conditions, use the biomass fuels, and meet the needs of the people in geographical areas in which the stoves will be ultimately deployed; · Aim to meet or exceed the highest level of stove performance for total and indoor emissions, efficiency, and safety; and · Achieve field performance that is comparable to stove performance in laboratory testing. These goals are intended to drive technology developments that can support the widespread adoption of affordable, user-desirable stoves that provide significant health benefits, labor and financial savings, and soil and forestry benefits.
