Quantitative metrics of stove adoption using Stove Use Monitors (SUMs).
The sustained use of cookstoves that are introduced to reduce fuel use or air pollution needs to be objectively monitored to verify the sustainability of these benefits. Quantifying stove adoption requires affordable tools, scalable methods and validated metrics of usage. We quantified the longitudinal patterns of chimney-stove use of 80 households in rural Guatemala, monitored with Stove Use M...
متن کاملDesign of a Battery-Powered Induction Stove
Many people in the developing areas of the world struggle to cook with stoves that emit hazardous fumes and contribute to green house gas emissions. Electric stoves would alleviate many of these issues, but significant barriers to adoption, most notably lack of reliable electric power, make current commercial options infeasible. However, a stove with an input power of 24V DC elegantly solves th...
متن کاملA Wood-gas Stove for Developing Countries
Through the millennia wood stoves for cooking have been notoriously inefficient and slow. Electricity, gas or liquid fuels are preferred for cooking when they can be obtained. In the last few decades a number of improvements have been made in woodstoves, but still the improved wood stoves are difficult to control and manufacture and are often not accepted by the cook. Gasification of wood (or o...
متن کاملCurrent Conveyor Equivalent Circuits
An equivalence between a class of (current conveyor) CC II+ and CC IIcircuits is established. CC IIequivalent circuit uses one extra element. However, under certain condition, the extra element can be eliminated. As an illustration of the application of this equivalence, minimal first and second order all-pass filters are derived. In certain cases, it is possible to compensate the effect of the...
متن کاملProcedural design of a CMOS current conveyor
1 Facultatea de Electronică şi Telecomunicaţii, Departamentul Electronică Aplicată Bd. V. Pârvan Nr. 2, 300223 Timişoara, e-mail [email protected] Abstract – This paper presents a new procedural design sequence for the design of a CMOS current conveyor. It is based on the structured design approach and consists in circuit partitioning, derivation of the specifications for each basic an...
