Four gasifier stoves, all developed at the Appropriate Technology Center (APPROTECH Center) of CPU, were evaluated in this study in terms of fuel consumption rate, percentage char produced, fire zone rate, thermal efficiency, and electric energy consumption rate. These include: Gasifier A or the cylindrical-type single-burner, top-lit updraft (T-LUD); Gasifier B or the cylindrical-type double-burner, T-LUD (for household use); Gasifier C or the conical-type double-burner T-LUD (for household use), and Gasifier D or the conical-type double-burner T-LUD (for industrial use). Evaluation was conducted at the APPROTECH Center on April 23 to May 29, 2007. Results of the study revealed that Gasifier A significantly (p<0.01) had the highest percentage production of char and thermal efficiency while Gasifier D significantly (p<0.01) produced the highest fuel consumption rate. In general, however, all the three double-burner stoves (Gasifiers B, C, and D) significantly (p<0.01) had higher fire zone rate and consumption of electric energy compared to Gasifier A since these three stoves have two burners and use an electric blower as air moving device, thus consuming more fuel and electric energy. The gas emitted by the gasifier stoves were estimated to contain from 20 to 24% carbon monoxide, 13 to 23% hydrogen gas, 8 to 15% carbon dioxide, 38 to 42% nitrogen, 0 to 2% methane and 7 to 9% water or moisture. Among the gasifiers evaluated, only Gasifier A has the economic advantage over the LPG stove making it ideal when used at the household level. Due to their high investment cost and low economic return, the double- burner stoves (Gasifiers B, C, and D) can still be used for bigger and longer cooking operations.

A proliferation of choices available to consumers as they select a major cooking appliance necessitated the development of a Buyer’s Guide which will provide consumers with generic information by which they can compare range cooktops and microwave ovens. The microwave oven is included because it is often used in the place of a cooktop. The Buyer’s Guide for Range Cooktops and Microwave Ovens as an information resource is designed to be used by consumers to assist in making an informed purchase decision. The study was conducted in three phases: 1) identification of items included in the Buyer’s Guide; 2) establishment of test procedures; and 3) focus panel evaluation of the Buyer’s Guide. Phase 1 - Eleven items considered to be important in making purchase decisions were identified by members of the Virginia Retail Merchants Association and by Virginia home economics Extension agents. Items rated as important for inclusion were: purchase price, maintenance, life expectancy, operating costs, energy use, speed of heating, evenness of heating, heat retention, heat recovery, ease of cleaning, and ease of use. Phase 2 - Using standardized test procedures, data were obtained for the radiant coil electric smoothtop to allow the comparison of items found on the Buyer’s Guide with other types of range cooktops (conventional electric coil, gas burner, induction cooktop, smoothtop resistance coil, solid element) and the microwave oven. Phase 3 - Four focus panels were conducted to evaluate the Buyer’s Guide for Range Cooktops and Microwave Ovens for clarity of content, practicality of format, and its usefulness to consumers. The 26 focus panel participants recommended changes which were incorporated into the Buyer’s Guide for Cooktops and Microwave Ovens. They indicated a belief that the Buyer’s Guide would be useful for consumers seeking generic information by which to compare major cooking appliances. Further research is needed to evaluate the Buyer’s Guide for Range Cooktops

Silent film; Muncie Press cooking school demonstration of all gas self cleaning range, sponsored by Wolohan Lumber Co., This film originated from WLBC-TV and was (possibly) a part of a segment titled, “Week in Review.” The station was created in 1953 by Don Burton. WLBC-TV Channel 49 was sold in 1971 to a local non-profit group, who changed the station's callsign to the current WIPB-TV, now licensed by Ball State University., This archival material has been provided for educational purposes.
