Waste Energy System AKA Bioreactor



Off Grid, "Waste Energy System"
First Concept
The concept of the WES is to use a few forms of energy Solid, Liquid and Gas and introduce it into nature in 2 of these 3 forms and using the last as energy. First form is compost (solid form), it gives off a lot of hydrogen and CO2. Well we really can't use CO2 in anything so we have to find a way to get removal of this section of the waste energy and product something we can use. So what eats CO2. Algae! So we funnel the gas to the algae and water (Liquid form) a few times and what we should be left with is hydrogen and Oxygen. With these two elements we have and can be used a fuel for today's standers. You can burn this fuel for warmth or even power a gas generator to spin a electric generator therefore powering an inverter to power your light bulbs.

What is the waste of this process? Don't forget you can feed each other in the opposite direction such as water goes back to the algae tower. Excess Algae can be dumped into the Compost. Compost can be used to make good fertilizer
Fuels needed: Second Concept AKA More precise
When organic material (including human feces, animal waste, and plants) is digested by microorganisms in the absence of oxygen (anaerobic digestion) a gas is released consisting of 60% methane and 40% carbon dioxide. This gas is typically called biogas and because it can be ignited, it may be used as a cooking and heating agent.
Human Waste Bioreactor By combining the human feces with sawdust, we can increase the overall ratio inside the digester. The 60% methane and 40% carbon dioxide can then be filtered using a Algae Bioreactor removing CO2. We are then left with methane, hydrogen and Oxygen all can be used as fuel. After this is burned it can then be pumped back into the Algae Bioreactor to be reprocessed.
So storing the fuel/gas can be done using old Propane tanks. conversion process

pH and the Well-Buffered Digester


To measure the acid or alkaline condition of a material, the symbol "pH" is used. A neutral solution has pH = 7; an acid solution has pH below 7; and an alkaline solution has pH above 7. The pH has a profound effect on biological activity, and the maintenance of a stable pH is essential to all life. Most living processes take place in the range of pH 5 to 9. The pH requirements of a digester are more strict (pH 7.5-8.5, Fig. 7).
(Table 1) Problems with pH.
Condition Possible Reasons "Cure"
Too acid (pH 6 or less) 1) Adding raw materials too fast Reduce feeding rate; Ammonia
2) Wide temperature fluctuation Stabilize temperature
3) Toxic Substances
4) Build-up of scum Remove scum
Too Alkaline (pH 9 or more) 1) Initial raw material too alkaline Patience Never put acid into digester
If the pH in the continuous-load digester becomes too acidic (Table 1), you can bring it up to normal again by adding fresh effluent to the inlet end, or by reducing the amount of raw material fed to the digester, or as a last resort, by adding a little ammonia. If the effluent becomes too alkaline, a great deal of C02 will be produced, which will have the effect of making the mixture more acidic, thus correcting itself. Patience is the best "cure" in both cases. NEVER add acid to your digester. This will only increase the production of hydrogen sulfide.

Scrubbing

After producting methane it would need be Scrubbed by pass the gas through lime water to remove C02 and iron filings to remove corrosive hydrogen sulfide. Since lime water removes CO2 by assumption is that algae produces lime and has the same affect.
