Documentation of the project Laigret

Laigret project: technical documentation and information

Here are the information that we were able to meet and in the Laigret project.

These documents come from research done on this topic: Laigret project, documentations. The reader to refer to it for additional information.

Summary of the article:
- Precise date of the Laigret experiment: June 15, 1947
- A new name appears: Mr Laugrier, rector of the Academy of Algiers.
- The strain is identical to the other articles
- Biomethane is not ONLY of cellulosic origin! (important)
- There is no CO in Laigret methane (unlike conventional biogas)
- Oleic acid gives the best results
- Analyzes made by the Department of Mines in July 1947! Documentation to seek!
- 1 g of soap = 1cm3 of oil (in another article we had 4 grams for 3 cm3)
- Temporal aspect: the transformation is very fast (unlike mineral oil from which the false popular belief arises that it takes millions of years for oil…!). Certain oils can therefore be synthesized very quickly!
- And finally, and this is what brings a lot of hope to the project: Laigret was discreet with regard to the Press (so the sources of information that we have for the moment) on many points for economic reasons. Which probably means that some (the most interesting?) Results have never been published.
