| Super Bacteria to be used to make Biofuel in Maryland |
| 2008-03-14 |
| From a U of Md Press Release University of Maryland research that started with bacteria from the Chesapeake Bay has led to a process that may be able to convert large volumes of all kinds of plant products, from leftover brewer's mash to paper trash, into ethanol and other biofuel alternatives to gasoline. ---- They haven't gotten this to the 1-gallon a day production stage yet so they are looking to have some real business buy their start up (although they are pretending otherwise). |

| #12 Can we get a demo plant to "render" lard ass Kennedy into fuel, after all Mass is HIS State. |

| #11 3dc, a very large number of algae biofuel ventures over the past five or so years have turned out to be investment scams. Just a warning. |

| #10 The waste water, heat and Co2 from Power stations would be great for these Algal farms. |

| #8 Using biomass inherently can't be as efficient as using algae, which just needs water, sunlight, and waste CO2 and NOx gases. The whole process would begin with a water treatment plant, most likely getting effluent water from a large city. After separating out the solids and processing like a regular treatment plant, but before chlorination and fluoridization, it would send the water to an adjacent algae farm. The algae farm would have rows of shallow but wide tanks in the ground, like the rows of a farmer's field. These would have ordinary pipe on the bottom to bubble waste CO2 and NOx gasses through the water, and be covered with "self-cleaning" glass to allow sunlight, but not foreign algae in, yet not let the unused gases out. Machines under the glass would slowly move up and down through the rows, harvesting algae to sluices on the side of the rows, where it would be flushed or conveyed away for processing. After the effluent water had flowed through the algae farm, it would go back to the treatment plant for a final filtration, chlorine and fluoride before being returned to the city water system. The day's crop of algae from a dozen acres of algae farm would be hauled off at night for processing into biodiesel and a little ethanol. Unlike using biomass crops, which are harvested about three times a year, or garbage, which also is produced at irregular intervals and quality, an algae farm south of the Mason Dixon would be in production every day for perhaps 10 months out of the year, growing predictable quantities of algae. Once production conditions were known and perfected, the methods and production of biodiesel could be scaled to local and regional need. Ironically, area factories that provided the waste CO2 and NOx would want to discontinue expensive scrubbing processes, to deliver as much of the waste gas as possible. So they would not just save money, but make money, from their waste. |

| #6 assume 200 millon tons/year of solid municipal waste in US assume 80% is biomass assume 25% of biomass can be converted to fuel assume 300 gallons fuel per ton of converted biomass, that would be about: 200,000,000 x 0.8 x 0.2 x 300 = about 10 billion gallons current motor vehich fuel consumption/year is about 140 billion gallons so, even if we could process all municipal waste, a lot of other stuff would have to be processed to make a big difference |

| #2 If they can turn pretty much any organic waste into fuel, landfill owners are going to be (or should be) stampeding to make this viable. Imagine if you're the owner of "Mount Rumpke" here in Cincinnati -- decades of household waste at hand, relatively easy access to it, and a way to turn it into auto fuel. |

| #1 Not necessarily. This is the biofuel future. Corn as basis is merely transitory, because the process has been known to distillers for hundreds of years. Decomposing hydrocarbons of all types, then reconstituting them into products which are desired will become common within ten years. Real progress towards fuel independence will follow. Ethanol itself is transitory. Butanol is the most desirable auto fuel. Pure hydrogen could also work if storage density issues can be solved. Now that a pathway for synthesized propane has become known, it too could be a viable candidate for auto fuel as well as heating fuel. The MIT group who pioneered the synthetic propane did not wait for someone to buy their technology. They incorporated and are seeking funding for scale up. The technical pathway is well known. Only economy of scale is to be determined. These are tremendous steps forward. The end of the Saudi piggy bank is in sight. It's like a distant mountain range, still far away, but within sight. |
