Chimney - Removing Carbon Dioxide AND Growing Food

My web-pages for the HeatGreen home heating systems all include a discussion of massive research which was done in the 1990s that discovered that if the natural concentration of carbon dioxide in the air tripled, from the current 400 ppmv up to 1200 ppmv, that virtually all plants grow around five times as fast, as well as growing stronger and better. We then mentioned how a small greenhouse attached to our HG 3a device could then produce FIVE TIMES AS MUCH FOOD by using an HG device. Amazingly, the larger quantity of fruits and vegetables are also sweeter and healthier! During the 1990s, more than a thousand Scientific Research Studies were done that discovered that virtually every type of plant seems to grow about five times as fast, and with better overall quality, if the plants grew in an atmosphere that had about three times as much Carbon Dioxide in it than natural atmosphere now has. Since the Earth's atmosphere now contains just under 400 ppmv (parts per million by volume), a wonderful new possibility now seems available.

I now see value in very large scale use of the system I discussed early in 2007. I now see that if a farmer had 100 acres of land which he could cover over with a greenhouse roof, and a nearby industrial factory chimney could send 10,000 tons of Carbon Dioxide (20,000,000 pounds) into that greenhouse, two good results can be had.

This would remove a lot of Carbon Dioxide from the atmosphere (the 10,000 tons), while also producing 500 acres worth of fruits or vegetables on 100 acres of land! The Research done in the 1990s also found that nearly every type of plant grew BETTER in the high carbon dioxide atmosphere, where virtually all fruits were larger and sweeter and of higher overall quality. Crop plants such as corn or wheat grew faster and stronger, and were healthier.

Two very different serious problems might be solved at the same time, supplying five times as much food for desperate people and also removing a significant amount of Carbon Dioxide from the atmosphere to reduce Global Warming.

The biochemistry involved shows WHY both of these benefits occur. The chemical reaction of Photosynthesis is generally this one:

(6) H2O + (6) CO2 + sunlight energy gives C6H12O6 + (6) O2.

In molecular weight units, this also says 6 * 18 + 6 * 44 + sunlight equals 180 + 6 * 32. We see that we have 372 on the left and 372 on the right, which Conserves Mass. Say we have 5,000 tons of Carbon Dioxide which are naturally in the 50,000,000 cubic feet of air in the giant greenhouse. The biochemistry of the Photosynthesis therefore tells us that we need to use up about 2100 tons of water vapor, and we would create about 3600 tons of plant materials and 3500 tons of oxygen. Only a small fraction of the plant material actually becomes the desired fruits or vegetables, which we will here take as 10%, or in other words, 360 tons of actual crop from inside our 100 acre field.

Say that we add an additional 10,000 tons of Carbon Dioxide (from the industrial chimney effluent) which we added to the giant greenhouse. For all this Carbon Dioxide inside the greenhouse to now all be Photosynthesis processed into plant material, our numbers are now all triple what they were naturally. We therefore also need to add an additional 4200 tons of water vapor (which is also all available from the industrial chimney effluent). We will now create a total of 10,500 tons of oxygen inside the greenhouse, as well as 10,800 tons of plant materials (glucose). A little better percentage of this now becomes the actual crop, which now provides us with around 1,800 tons of actual crop. We therefore get about five times the number of bushels of fruits or vegetables, while removing that undesirable 10,000 tons of Carbon Dioxide from that industrial chimney effluent gases. In addition, we get a bonus of 10,500 tons of oxygen in the process!

This is a win-win-win situation, isn't it?

Soybeans at the current 390 ppm atmospheric grow at the rate of around 14 grams/square meter/day. If this was our crop in our 100 acre greenhouse, this would be about 5.7 metric tonnes of soybeans per day or roughly 1000 metric tonnes of soybeans per year in the greenhouse. The additional carbon dioxide we provide inside the greenhouse would increase this to about 5,000 metric tonnes of soybeans per year, roughly giving a fivefold larger crop.

Pretty much any crop or other plants, or even flowers, benefit in the same way.
