Generating Electricity at Ocean-Air Interface

Ari Morse and Cody Nabong

Procedure

• Calibrate thermocouples.

• Verify online temperatures.

• Calculate average temperature difference.

• Choose example Peltier unit.

• Calculate # Peltier units, cost, and space required.

• Compared to same values for geysers and hydrothermal vents.

Thermocouple Calibration and Example Peltier Unit

• V = 4 x 10-5(T) - 3x10-5 Volts

• 127 thermocouples / unit

• \$8.50 / unit

• 30mm x 30mm planar area required / unit

Ocean Temperature differences

• Average yearly temperature difference of 10.9 C for Charles river.

• DC voltage output for 1 TC= 4.05 x 10-4 Volts

• # Peltier units needed to provide 12V = 233.3

• Cost = \$1983.31

• Area required = .21 m2 = 2.26 ft2

Possible Uses

Heat from sun

Boats

• Starter

• Power boat

• Possible "hot pocket"

Emergency Ocean Blanket

• Rolls up for storage

• Unroll and throw in ocean for emergency power

Geysers

• Temperature difference of 138 C for Old Faithful and very cold air.

• DC voltage output for 1 TC= 5.49 x 10-3 Volts

• # Peltier units needed to provide 12V = 17.2

• Cost = \$146.29

• Area required = .17 ft2

Vents

• The thermocouple we calibrated has a maximum temperature of 350o C.

• The water exiting ocean vents can exceed this, and the surrounding ocean water is 2o C

• DC voltage output for 1 TC= 1.39 x 10-2 Volts

• # Peltier units needed to provide 12V = 6.8

• Cost = \$57.82

• Area required = .07 ft2
