What are the 3 end products of the light reactions

I created this instructable to show how to build a simple algae based CO2 scrubber for home or apartment use. The basic design shown here will scrub its own consumption and approximately 24 pounds of carbon dioxide from the atmosphere every year. This is approximately the CO2 produced in the production of 17kW of electricity. This device may be scaled up to process larger quantities of CO2.

The carbon dioxide is consumed by the algae which release oxygen. In part I the scrubber consists of a 2 liter reactor vessel and a small aquarium air pump. The bottle contains a solution of water, algae and nutrients. Room air is passed through the bottles using a standard aquarium bubbler stone where the CO2 is absorbed by the algae and oxygen released.

In later parts this basic design will be expanded provide more flexibility and increased production.

Maintenance is simple and straightforward as any house plant. About twice a month I add a couple drops of liquid plant food. The color of your home scrubber may be kept at any desired color range by controlling the food. If the algae gets too dark for your taste simply wait until the color begins to lighten before feeding again, if its too light try adding another drop of nutrient or feeding more often to increase the population.

Once or twice a year its probably not a bad idea to clean the scrubber. Save enough medium from one of the lightest bottles to reseed them. Then empty them into your compost heap, the sink or the toilet and restart them using tap water and the reserved medium.

All that being said, let's take a quick look at the tools and materials we'll be using then we'll get started.

Making sense of the data
The data cited above suggest that carbon dioxide and oxygen haveantagonistic (opposite) actions in photosynthesis and act in a competitive manner.

Advantages of C4 metabolism
Plants that exhibit this type of photosynthesis are characteristic ofhot, tropical environments that have a high light fluence.

The key benefit of our LED grow light is its remarkable ability to mimic natural sunlight by emitting a full spectrum of light. Red and blue light wavelengths activate photosynthesis, but are not the only wavelengths plants need. Oversaturating your plants with only red and blue wavelengths actually causes them to go dormant, leading to under produced plants.

fluence for tobacco and maize in ambient oxygen (21%); (b) light saturation point - point at which increasing fluence yields a constant amount of photosynthesis; (c) light compensation point - fluence at which the amount of photosynthesis just equals the amount of respiration; and (d) note that plants that photorespire (like tobacco) have a higher light compensation point and light saturate.

No, a breeder reactor is not the cornerstone of a secret WMD project. The word reactor is used in this context as shorthand for "reactor vessel". In this case the reactor vessel will hold algae, water and nutrients for the purposes of breeding the algae, hence the name "breeder reactor".

We'll start with the 2L soft drink or water bottle and the 3/16" drill bit. We're going to drill a hole in the center of the plastic cap, insert a piece of 1/8" rigid plastic tubing, glue that in place. Then we will fill the bottle with water, add the algae culture and nutrients and wait for nature to take it's course.

Fit the drill bit into the drill and drill a 3/16" hole in the center of the plastic cap. Cut off a 10" section of rigid plastic tubing with scissors. Feed that through the hole in the cap until approximately 1" projects from the top.

Cut off a 1" piece of the flexible plastic air hose and remove one of the air stones from the 6 pack. Attach the flexible tubing to the bottom of the air hose and attach one of the air stones to the other end.

Fill the bottle most of the way with dechlorinated or fresh water. Now add the algae sample we took earlier. A funnel isn't strictly required as long as most of the culture makes it into the reactor.

Fill the bottle up the rest of the way with dechlorinated water and insert the cap bubbler assembly. Your breeder reactor is now charged and ready.

Now take out the air pump. I selected the Tetra 799 based on its low capacity, inexpensive price and being in stock at PetSmart. Any air pump will suffice.

Decide where you will place your reactor, remember that this is a plant which uses photosynthesis. The more direct sunlight it recieves the better. Locate an outlet for the pump. Cut a length of flexible tubing that will reach from the air pump to the input located on the cap. Attach the pump to the reactor with the tubing. Tighten the plastic cap down and then open it 1/4 turn. This will allow the scrubbed air and generated oxygen to escape.

At this point you are actively scrubbing carbon and breeding algae for the next phase of the reactor.
