Abstract: Disclosed herein are aspects of a system for coupling electrochemical marine carbon capture with photosynthesis. In some aspects of the present disclosure, the system comprises an electrochemical cell that converts saline water into (i) a base stream, (ii) an at least partially deionized water stream, and (iii) an acid stream. In some aspects, the system further comprises a biomass cultivation unit in fluid communication with the acid stream, the biomass cultivation unit comprising a photosynthetic organism. The acid stream catalyzes release of CO2 in a growth medium for the photosynthetic organism to accelerate growth of the photosynthetic organism relative to growth without the acid stream and facilitates CO2 storage by the photosynthetic organism. Also disclosed herein are aspects of a method for coupling electrochemical marine carbon capture with photosynthesis.

Abstract: A method for enhancing photosynthetic productivity in aquatic environments through precision electrochemical nutrient delivery can involve deploying a pair of electrodes within a water-based matrix, where the first electrode functions as an anode and the second as a cathode, forming an electrochemical cell with the water serving as an electrolyte. At least one of these electrodes can be composed of or coated with an inorganic nutrient, facilitating a precise and low-concertation release of nutrients through controlled electrochemical nutrient delivery (CEND). A specified potential difference can be established between the electrodes to control the rate and amount of nutrient delivery. This such a potential difference can facilitate a precise addition of an inorganic nutrients into the water, such as to promote a growth or carbon capture capabilities of photoautotrophic organisms.

Abstract: A new embodiment LED traffic light 40 having a housing 49 that provides at least three signal lights 42, 44, and 46. The three signal lights 42, 44, and 46 are all embedded in a single opening 50 of housing 49. The LEDs for signal lights 42, 44, and 46 are arranged in a generally common area that allows activation and display of one of the signal lights in a corresponding symbolic shape (i.e. universal symbol or words). Red signal light 42 has red LEDs 41 spread out and arranged in an octagon shape (i.e. stop sign shape). From a distance or afar, however, it may be difficult for persons to distinguish between the octagon shape and the circular shape (i.e. stop and go signals respectively). Therefore, a border 52 of contrasting color LEDs 54 (i.e. different color other than the color of the octagon) is placed around the octagon shape and illuminated to further enhance and define the stop sign or octagon shape thereof. The border 52 may be made to blink or flash (i.e. by blinking all of the LEDs 54).

Abstract: LED traffic light 30 having a housing 39 that holds at least three different signal lights 32, 34, and 36. The three lights 32, 34, and 36 are each embedded in an opening 50 of housing 39. The LEDs for traffic signal lights 32, 34, and 36 are arranged in symbolic shapes (i.e. universal symbols or words) that further represent one of the traffic signals. Red signal light 32 has red LEDs 31 arranged in an octagon shape (i.e. stop sign shape), and yellow or amber signal light 34 has yellow LEDs 33 arranged in a triangle shape (i.e. caution sign shape). Green signal light 36 has green LEDs 35 arranged in a circular shape. The preferred embodiment is a single lens traffic light 40 having a housing 49 that provides at least three signal lights 42, 44, and 46. The three signal lights 42, 44, and 46 are all embedded in a single opening 50 of housing 49.
