Benefits of Radioisotope Thermoelectric Generators
Since the 1960's the United States has had the capability to reach beyond the planet Earth with the aid of satellites and interplanetary space probes. As probes such as the...
The Effect of UV Radiation on THM Formation in Drinking Waters
This study was undertaken to investigate the feasibility of using combined UV radiation/chlorination process in drinking water treatment for disinfection while producing lower concentrations...
Disinfection of Wastewater Effluents with Electron Radiation
A full scale electron irradiation unit is being tested at the Virginia Key Wastewater Treatment Plant in Miami, Florida. On-going experimentation is evaluating the use of high energy electrons...
A Commonality Assessment of Lunar Surface Habitation
This paper presents a commonality assessment of lunar surface habitation. Thus far, NASA has baselined the space station common module for initial lunar base habitation; however, nothing...
Extraterrestrial Applications of Solar Optics for Interior Illumination
The major purpose of this paper is to introduce a terrestrial technology that we believe has potential extra-terrestrial applications. The technology is Solar Optics, which is subdivided...
Radiation Hazards to Space Construction - The Energetic Particle Environments
Many aspects of the space environment are recognized hazards for activities above the Earth's atmosphere. One of the most dramatic hazards is that posed by the diverse energetic...
Containerless Coating Processes for Large Space Structures
Large space structures (LSS) in low earth orbit (LEO) must be able to withstand the deleterious effects of in situ ultraviolet radiation, atomic oxygen, and thermal-cycling-induced microcracking....
Thermal Effects on Large Space Structures with Fixed Attitude
Radiation thermal effects are studied simultaneously on the orbital motion and axial deformation of a very large axially flexible space structure executing planar pitch motion around the...
The Second Generation Space Station
Several aspects of optimizing space operations have been examined to identify key components in establishing a more efficient space infrastructure. A second generation space station situated...
Solar Power Satellite - A Re-Visit
The United States should renew activities investigating the production of baseload electrical power for use on Earth from space. Technology change, world events, and the dictates of the...
Power Systems for Production, Construction Life Support, and Operations in Space
As one looks forward to mankind's future in space, it becomes obvious that unprecedented amounts of power will be required for the exploration, colonization, and exploitation...
Solar Water Heater for NASA's Space Station
This paper describes an investigation of the feasibility of using a solar water heater for NASA's Space Station. During the investigation computer codes were developed to...
Indirect Solar Loading of Waste Heat Radiators
Waste heat from space based power systems must ultimately be radiated away into space. The local topology around the radiators must be considered from two standpoints: the scattering of...
Non-Ionizing Radiation Exposure in Space Activities
Non-ionizing radiation exposure has received considerable attention over the past few years due to the potential health hazards involved. Different limits have been set with no international...
U.S. Coast Guard Experience with Wave Turbines
Since 1980 the United States Coast Guard has been developing a lighted buoy for exposed areas and congested harbor entrances. The buoy hardware is of conventional design while the signal...
Penetrative Convection in Mixed Layer Models
While surface heat transfer is important in lakes and reservoirs, solar radiation, which penetrates the water surface and is absorbed in the water column, also exists. In this work, a...
Dormant Season Evapotranspiration in Alfalfa
Weekly values of maximum temperature, minimum temperature, and solar radiation were examined for their effect upon weekly dormant season evapotranspiration (ETdorm) in perennial alfalfa....
CWSI and Stomatal Resistance of Cotton and Soybeans
A new instrument, Scheduler(TRADEMARK), has been developed to measure the onset and duration of plant water stress. This device consists of a sensor package (containing an infrared thermometer,...
Long-Range Forecasts of Water-Supplies
Many engineers and water-users have an urgent need for reliable predictions of future rainfall and water supplies, extending many months or years ahead. Correlation of known historic rainfall...
Economical Computer Controls for Low Head Hydro
Small power systems based on renewable energy sources such as low head water falls, wind, solar and ocean tides all suffer from stochastic changes in input power. Economically viable,...
