We turn low-efficiency, polluting combustion-driven power plants into high-efficiency Oxygen, Water, Biomass and Electricity-producing factories. Get one to improve your city!
At www.TheOxygenFactory.net, we recycle carbon by burning hydrocarbons (coal, natural gas, petroleum coke), and your garbage to generate electricity, then capturing and separating the exhaust gases, one of which being the headline-grabbing greenhouse gas, CO2. Through enhanced photosynthesis, we are able to turn waste CO2 into Oxygen, Water, and Biomass, items vital for life on Earth. Additionally, a second exhaust gas captured is steam, meaning, beyond the water required at startup, our design is a net water producer. And we don't have any unsightly smokestacks or cooling towers, either!

Oxygen demand on Planet Earth continues to increase due to the breathing needs of now 7.3 billion humans and their need to oxidize increasing amounts of hydrocarbon fuels for energy. Our design will produce oxygen economically at large scale to head off future declines in this vital resource.
Oxygen is the main byproduct of recycling carbon dioxide (CO2) in the hydroponic biological growth of cyanobacteria like Spirulina. Cynobacteria, formerly known as blue-green algae, are autotrophs which require the nutrient CO2 for growth in visible light to produce biomass. The process is very slow in nature but rapid under controlled conditions as in our U.S. Patent No. 8,673,615. We developed this technology to make use of the CO2 recovered from power plants utilizing our O2/CO2 combustion condensing boiler system detailed in U.S. Patent No. 6,907,845.
CO2 is composed of 27% carbon (C) and 73% oxygen (O2) by molecular weight. Obviously the greatest economic value to be gained from the biological process in the 8,673,615 patent is to recover both the biomass and all of the oxygen. The biomass when dried is 50% carbon and has multiple uses for fuel, fertilizer, animal feed and a human food supplement. The oxygen may be released to enrich the air we breathe; or, it may be recycled through the power plant combustion process where the oxygen combustion method embodies the potentially emission-free condensing boiler.
This recycling of oxygen for fuel combustion is being estimated to reduce the cryogenic air separation requirement by about 40%, resulting in a large efficiency improvement. Or alternatively, the plant power output may be increased about 40% by adding more fuel and turbine/generator capacity.
The above processes will be adaptable to another technology we are developing called Rotary Kiln O2/CO2 Combustion with a Condensing Boiler. It will improve efficiency with lower capital and operating costs compared to current pulverized coal air-fired plants. It will have no emission problems.

CHICAGO--(BUSINESS WIRE)--Krebs & Sisler LP, a suburban Chicago energy research firm, has developed a low-cost CO2 separation and recycling method called Enhanced Photosynthesis and Photocatalysis Water Treatment/Biomass Growth Process. It is described in U.S. Patent No. 8,673,615 granted March 18, 2014. It neatly complements the O2/CO2 combustion and condensing boiler system of our U.S. Patent No. 6,907,845 which separates and recovers CO2 and all other combustion-generated exhaust gases.
“We discovered economical CO2 recycling in the finding that hydroponic biomass growth can be increased more than 100 times the natural rate by continuous CO2 infusion and simultaneous LED visible light saturation. This improvement is outlined in the 8,673,615 patent,” stated inventor Bill Krebs.
In O2/CO2 combustion, oxygen is diluted with CO2 for temperature control of the fuel oxidant used to combust coal, petroleum coke or natural gas. Excluding the nitrogen that is present in air-fired combustion enables cost-free recovery of both the condensate and the CO2 from a condensing boiler. The condensate and CO2 are pumped into deep and slowflowing water channels, saturated in the visible light spectrum of light-emitting diodes (LEDs). A photocatalyst mineralizes organic and inorganic compounds for absorption into a cynobacterial biomass like Spirulina. The absorption of minerals in the growing biomass concurrently purifies the flowing water. These processes when optimized will reliably operate at high efficiency with no harmful emissions or effluents into the environment. They will also produce a carbohydrate and protein-rich biomass useful for fuel, fertilizer, animal feed or a human food supplement.
“We are now developing a combination coal, rotary kiln, O2/CO2 combustion condensing boiler. It will have significant cost, efficiency and emission advantages,” Krebs explained. “A critical factor for heat transfer efficiency is that the crushed coal rotary kiln method of combustion allows three to five minutes or more for complete fuel-burn and heat-transfer time, whereas the pulverized coal combustors presently in use allow only three to five seconds.” Krebs continued, “Today’s air-fired plants operate at an average 34% fuel efficiency. Our O2/CO2 combustion method, when combined with a condensing boiler, can more than double plant fuel efficiency and thereby reduce both the fuel and oxygen requirements by half.”
“The many applications and advantages of this combination of processes include the conversion of waste CO2, wastewater and saltwater to profitable biomass and demineralized drinking water, improved electric power production efficiency, virtually no harmful emissions, relatively low capital and operating costs at large scale, improved fuel flexibility, improved revenues and compact use of space compared to presently operational electric power production methods which waste CO2, heat and water vapor into the atmosphere,” summarized Mr. Krebs.
“Sequestration has been proposed as a method of disposing of CO2, but it is expensive and wastes carbon and oxygen, two elements essential for life on Earth,” Mr. Krebs noted.
