Summary of the article:
- Precise date experimentation Laigret: 15 1947 June
- A new name appeared: Mr Laugrier, rector of the Academy of Algiers.
- The strain is identical to other items
- Biomethane is not necessarily THAT cellulosic origin! (important)
- There is no CO in methane Laigret (unlike conventional biogas)
- Oleic acid gives the best results
- Analyses made by the Service des Mines in July 1947! Documentation looking!
- 1 g soap = oil 1cm3 (in another article we had to 4 3 gram cm3)
- Temporal aspect: the processing is very fast (unlike mineral oil from which comes the popular misconception as what it takes millions of years for oil ...!). Some oils are synthesized very quickly!
- And finally, and this is what bcp door of hope to the project: Laigret was discreet with respect to the press (hence souces of information we have at the moment) on many point for economic reason. This probably means that some results (the most interesting?) Have never been published.
