| Description |
The Naval Surface Weapons Center
(NSWC) is developing parameters to provide power for the cavitation erosion cleaning
technology developed in Project No. 4. These
parameters are required for a diver or a free swimming submersible to carry the device
untethered. Hydrogen gas is generated by reaction of lithium and water. The energy density
from the lithium batteries is expected to be much greater, saving weight and space. The
pressure energy can be generated without converting to an electrically driven pump. Safety
is not a problem. |
| Progress |
Complete. Test results indicate
that required pressures of 10,000 psi. for a 1-minute operation requires 1-pound of
lithium at a cost of $20.00 per pound. In-situ testing of the system was started but has
been indefinitely postponed due to budget considerations, the project was canceled. See
report from Project No. 7 titled `EAVE-East
Cavitation Cleaner Feasibility Demonstration, September 30, 1975. |
