6 B. J. WILSON OPERATION IN THE OPEN OCEAN AS COMPARED WITH LABORATORY OPERATION The data presented in Fig. 6 indicate that this type of Mg-anode/inert-cathode system will operate satisfactorily in an actual oceanic environment. Although such tests are only a first step in est-.lishing feasibility for ocean operation, they show that reaction products are not deleterious in excess of those experienced in the laboratory for periods up to about 2 weeks. Imminent ocean trials will expand these results for correlation over the 60-day or greater periods, corresponding to the long-term laboratory results discussed previously. Biological or .nicrobiological fouling, not encountered in the laboratory or 2-week sea trial, may arise to affect long-term performance. Inspection of Fig. 6 shows the necessity to maintain a spacing of 1/8 inch or greater for operating periods of this duration, i.e., days to weeks. lOG 90 so 70 50- L~76 I30 -- 2 233 /a 0 S3 4 7 65 3/4S{ 122 / 5 284 1/16 20-- 616 If$ 7 120 I/l S 728 -/16 ' F CELLS AZ-31 ANODES, 12" x 12" [ LA ATE CATHODESN,K+ Pd PLATED oII I1I 0 2 4 6 8 10 12 14 DAYS OF OPERAT-ON The curves of Fig. 7 indicate that results experienced in laboratory operation are representative of those encountered in the open ocean. The ocean tests were performed in 190 feet of water at Argus Island, 25 miles southwest of Bermuda. Cells tested in the ocean indicate a lesser tendency for clogging, due most probably to a greater flow of fresh electrolyte. With regard to the tradeoff between power output level and current level, in plate-type cathode versions, observation of the test results shows that clogging will not occur at 3.0 to 3.5 amperes/square foot for spacings at or greater than 1/8 lich for these operating dura- tions. Larger spacing appears to offer gains toward achieving higher power output for a clog-free operation but this incurs the penalty of greater electrolyte resistance drop. This dcop is particularly undesirable with respect to cold-temperature operation, as well as the * widening gap upon anode wear.

Product and Development Focus for Salgenx
Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our flow battery manufacturing.CONTACT TEL: 608-238-6001 Email: greg@salgenx.com (Standard Web Page)
