Effect of generalized wind characteristics on annual power estimates from wind turbine generators

Description: A technique is presented for estimating the average power output of a wind turbine using, as the wind characteristic input, only the mean annual wind magnitude. Hourly wind speeds are assumed to have a Rayleigh frequency distribution which requires a single parameter input (e.g., the mean value, variance or higher moment values). Based upon a general shape, for the wind speed versus machine output, a generic set of curves is developed to estimate the average power output of wind turbines. Also,… more

Relative availability of selected trace elements from coal fly ash and Lake Michigan sediment

Description: The concentration of greater than 1 ..mu..m coal fly ash particles in Lake Michigan surface waters was found to be 10/sup 5/ to 10/sup 6/ per liter. With an expected residence time of one year, this concentration implies a flux to the sediment of 10/sup 6/ to 10/sup 7/ particles/cm/sup 2//yr, or about 10/sup -6/ to 10/sup -5/ g/cm/sup 2//yr. The release of trace elements from fly ash and sediment has been studied using Chelex-100 resin to simulate leaching at high dilutions in natural media. Mn… more

Estimating monthly means of daily totals of direct normal solar radiation and of total solar radiation on a south-facing, 45/sup 0/, tilted surface

Description: Direct Normal, DN, radiation data is presently available for only a few sites in the country while total horizontal, TH, radiation is available for many locations. If a mathematical function relating DN and TH were established, solar engineers could estimate DN for any site for which TH data is available. Total radiated energy on a tilted surface, TT, is also of interest to solar engineers. A recently completed report includes TT values for a surface tilted at 45/sup 0/ for 26 sites. A function… more

Resource assessment of the Imperial Valley. Final report

Description: A resource assessment of the Imperial Valley has been made based on the use of the gravity anomalies as indicators of total excess mass. These data indicate a potential of producing electric power of 7 to 80 thousand megawatts for 30 years. Over half of the total potential is located in the Salton Sea Anomaly and approximately half of the potential of the Salton Sea field is water covered. An attempt has been made to assess not only the heat in storage in the fluid but also recoverable from the… more

Background information for the economic assessment of solvent fermentation processes

Description: An economic assessment of solvent fermentation processes was made. The question of whether or not the increased costs for petrochemical raw materials are sufficiently high now (or their projected costs in the 1980's), such that certain chemicals could be produced commercially from a cheaper raw material, say cellulosics, via various fermentation routes is considered. Specific examples under consideratin are n-butanol, propionic acid, and acetic acid. A qualitative approach was developed, based … more
