Improved generator for use with low-speed rotating machines. Final report
The goal of this project was to construct a low-technology, maintenance-free dc electrical generator suited for use with low-speed rotating machines such as windmills or waterwheels. The generator consists of permanent magnets affixed to the circumference of the rotating device, and stationary coils mounted on a semicircular frame. As the device rotates, the magnets move past the coils and magnetically induce an ac voltage in the coils. This voltage is rectified and stored in a battery. No gears, belts, or brushes are used, so the generator operates quietly and without maintenance. The purpose of mounting the magnets at the circumference of the rotating device is to achieve high relative velocities between magnets and coils even at slow rotations, in the hope of extracting energy from very light winds or slowly flowing water. Such a generator was constructed as part of a ten-foot-diameter windmill to test the concept. The generator easily reaches charging voltages at low speeds, and operates quietly without mechanical wear. But the charging current is very low in comparison to a wind turbine of conventional design. The experiment allows fundamental design problems to be identified.

Geothermal Project. Final report
The project was designed to take 95/sup 0/F water from an existing well and process it through a heat exchanger carrying supply water for our boiler make up and domestic hot water systems. The temperature of this water runs from 55/sup 0/F to 65/sup 0/F. In operation it was possible to raise the temperature of this water an average of approximately 12/sup 0/F. The amount of energy captured was recorded and it was found that one can capture approximately 199 x 10/sup 6/ Btu/Mo. Using current energy costs and a boiler efficiency factor of .8 a potential annual savings of approximately $11,104/year was calculated. The total cost of the project was $31,893.68. Using these figures a simple pay back period of 2.9 years was calculated.

Waste form/rock interaction leaching study using PNL 76-68 glass beads and Umtanum basalt. Part I
A 440-day single-pass continuous-flow leaching experiment was conducted at LLNL from September 1980 to December 1981. The data obtained for only one-third of the experiment are presented. The laboratory and data analysis of the remaining portion is still in progress at this time and a second report will follow at the end of FY83. This report concerns itself with the study of PNL 76-68 glass beads interacting with crushed uranium flow basalt and a simulated basalt groundwater under controlled conditions of temperature (25/sup 0/C and 75/sup 0/C) and flow rate (1, 10, and 300 ml/day). The main purpose of the experiment was to determine the absorption on basalt of Pu, Np, and some of the stable elements such as B, Mo, U, and Cs, as they were leached from the glass beads. Results are presented, as incremental and cumulative leach rates and sorption rates have been calculated for Pu, Np, B, Mo and U. also sorption profiles as a function of temperature and flow rate are graphically shown for Pu, Np, and U.
