Sea-Water Electronic Circuits for Salinity, Temperature and Pollution Monitoring

Two Pieces of thin plastic tube of 2 cm (a little less than one inch) diameter and length 1.2 meters (4 feet long) each were filled with Sea water and a twin wire plastic transmission line was electrically connected to the sea water contained in the two plastic tubes as shown. A TV set was also electrically incorporated in the circuit. TV (band-1) signals from the radiating TV tower of Trivendrum state capital city of Kerala, India where successfully received with good quality video signals. Thus a Sea-water TV antenna can be realized by sea ship travelers for their entertainment.

Gift of God-the Sea-water (containing abundant charged nano particles) is an ionic media with dominating presence of ions like Na+, Cl-, SO-4, Mg+, Ca+, K+, H+CO-3, Br+, BO+3, Sr+, F+ etc. Subjecting a portion of sea-water to varying EMF (amplitude and frequency) one can generate-transmit-receive E-M waves/pulses (in and around its surroundings) for creating electronic circuits. These circuits may find useful applications in sea-water salinity, temperature and pollution monitoring and thus can contribute significantly to new sensor technology, sea-water movement and possibly identify fish flock positions.

Researcher demonstrated for the first time realization of electronic components and circuits (R-C, Electronic Diode, R-C Filter, Logic Circuits, OR/AND gates, TV antenna, Amplifier Circuit made from Sea water (obtained from Surat city Gujarat, India).

Seawater Memristor

Using experimental setup. EMF of 1V 2V 3V (one at a time) were applied to the sea water contained in the glass bowl through the probes A-B and C-D continuously for 10 minutes (without unclosing the circuit). After every minute the value of Rw and Cw were recorded from the LCQR meter. Typical recorded data for EMF=1V,2V are depicted for positive and negative applied voltages. From the graphs one can see variation of Rw and Cw with time duration of EMF. Also the Rw and Cw for positive and negative voltages differ from each other. Similar behavior was observed form EMF=2V and 3V.

As the research work reported is somewhat unconventional in nature but in our opinion if one looks at it with a concentrated research mind set the following speculative applications can be spelt out:

1. Development of new type of monitoring sensors for sea-water salinity, temperature, pollution are envisaged.

2. Prediction of water mass movement (currents etc).

3. Dr. Shivprasad Kosta intuitively suggest that the ocean fish movement depends on the electrical charge state of ocean water. More precisely he thinks the fish lock may run away from temporarily created charged sea-water mass region.

4. Strategic survival and entertainment oriented simple sea-water application circuits like TV and emergency calls.

5. Sea-water fuel battery (extremely low power unit) using proper combination of electrode material(Mg-Silver etc).
