Quick apology for the Zillionth and one thread on Global Warming. A thread was launched in Chemistry about Co2 removal, and READ ONLY provided what I thought to be an excellent idea, that deserves to be heard in a environmental forum. His idea was that Algae was a good idea for removing co2, and I'm kinda arguing his point. I am NOT DEBATING WHETHER OR NOT GLOBAL WARMING IS A CRISIS, as there is OTHER (FOOD/FUEL) very applicable reasons to engage in this form of Farming. The "SEAWEED SOLUTION" Algae currently provides over 70% of the worlds oxygen, it is simple to grow and essentially only needs latch on points in order to thrive in the oceans. with simple anchor points we could establish floats. I am thinking baseball size plastic floats with 2 ten foot connecting wires (or substitute). We then connect these wires in an ever expanding framework regarding shipping lanes etc. Probably to maximum sizes of 100 miles by 100 miles. Warning beacons could broadcast from the borders. The main reason corn is considered a better choice for energy, is the lack of seaweed farms available. These farms would all convert co2 into oxygen, and they could be routinely towed to shore and harvested for food AND Fuel (forget global warming for a second.) Every industry producing Co2 should be required to add to these structures in amounts at least equal to their co2 output. Aside from hundreds of thousands (eventual goal) of square miles of oxygen farms, we would also have crop values in the form of Food/Fuel/Paper/Clothing/fertilizer/increased fish population, Positives. - The real estate value of the oceans is NILL. - Construction costs per square mile would be negligable. - Oxygen farms could help prevent or slow down Global warming (IF IT IS A THREAT, I AM NOT SAYING THAT IT IS). - CO2 sequestration would not be necessary - Fish populations would improve. - Possible uses as Hurricane inhibitor ???? (not thought out, idea is insulating problem areas of the ocean against sunlight, might hinder hurricane build-up. This is crazy that I'd even include this idea as it is "woo-woo", please go easy if quoting about this.) - Shipping lanes are mostly established and lighthouse type frequency emitters could warn ships, not that they'd sink if they collided with one, but... - It is a semi-NATURAL solution - The farms could be towed to shore for harvesting in whichever country we choose, for food. For agricultural aid, a navy ship could tow a few farms to whichever countries need the aid. -the farms could be towed to shore for harvesting in whichever country we choose for OIL. The main drawback for Algae as use for fuel is the lack of harvesting available. Corn however is already being grown and is a more viable option at this time. - The SEAWEED pulp could be used in production of paper. - The SEAWEED could be used to make clothes. - voters would get a bang for their buck. Negatives. - Why should we pay for clean air for every other country? although crop values could offset this argument. - Possible disruptions of natural ecosystems under the ocean.i,e, whales trying to surface,etc. The "wires" used should be easily detached so they do not form a net. - The low impact it would have as a pilot project. It would take years to develope structures capable of removing significant amounts of co2. We would litterally need hundreds of Farms say 100 miles by 100 miles each. before we could start "breathing easy" -possible hindrance to shipping lanes It seems viable, I am sure as technology ensues we will have more efficient scientific methods of reducing our co2 outputs, and sequestration, but the seaweed solution seems like a logical start. Save the world, grow food, remove co2 from the air, remove co2 from the air, and remove co2 from the air. ??? Any thoughts, and please look at the OTHER benefits before ANY tyraids about GLOBAL WARMING. Our oceans are the logical choice for farming foods/fuel/clothing, etc in our growing world.
