Offshore rectenna feasbility
A preliminary study of the feasibility and cost of an offshore rectenna to serve the upper metropolitan east coast was performed. A candidate site at which to build a 5 GW rectenna was selected on the basis of proximity to load centers, avoidance of shipping lanes, sea floor terrain, and relocated conditions. Several types of support structures were selected for study based initially on the reference system rectenna concept of a wire mesh ground screen and dipoles each with its own rectifier and filter circuits. Possible secondary uses of an offshore rectenna were examined and are evaluated
DEMAND FOR ORGANIC AND CONVENTIONAL FROZEN VEGETABLES
In this paper, we examine retail sales of organic and conventional frozen vegetables (broccoli, green beans, green peas, and sweet corn) using supermarket scanner data. Descriptive analysis includes comparisons of sales volume, prices, and market shares. Price and expenditure elasticities are estimated using the almost ideal demands system (AIDS).organic foods, frozen vegetables, almost ideal demand system, Consumer/Household Economics, Demand and Price Analysis,
