Microalgae multiply thanks to  to CO2 by photosynthesis.

In an enclosed space such as photobioreactors, its culture is controlled  and mastered.

The contributions (CO2 and minerals) are administered according to needs and the risk of bacteriological invasion  is decreased.

Exposure to light rays is optimized.

In this system,  the crop yields are exceptional (1gr / liter / day) .

There are a multitude of strains that grow in fresh or salt water, at a temperature between 4 ° C and 38 ° C.

The choice of strain is based on the amount of protein, omega 3, fat, carbohydrate and other elements  that they contain, depending on whether their  productions are intended for food or for the development of cosmetics, biofuels or bioplastics.  

The main strains cultivated are spirulina and chlorella.

After production, the biomass is dried  or consume  fresh for food or transformed by heat, pressure and agitation into a seaweed oil.

The production and processing costs are slowing down the industrialists for the large-scale marketing of this 3rd generation biofuel.

The production of this fuel can be done on buildings  existing and this is a huge advantage compared to previous generations (corn, wheat, sugar beet ...) which require a larger cultivation area, putting them in competition with other crops intended  to food.

This culture can treat water  worn out  and absorbed the CO2 from the ambient air or that emitted by the steelworks,  cement factories, breweries or other emitting activities.

In the race to empower buildings  and to the reduction of CO2 emissions, microalgae are, as for the origin of life, essential.
The development of  systems  production and processing, usable on a small and large scale and  adaptable to a maximum of structures (Roofs, walls, balconies, greenhouses, fences, bridges ... )  interior  and outside  seem essential.

Fuels can be used for heating buildings  as well as vehicles.

The transformation, at all  electric,  of the vehicle fleet leads to the scrapping of vehicles and therefore a waste of resources.

This fuel with almost zero carbon footprint and which emits  90% less fine particles than that produced by petroleum could allow us to continue using our existing vehicles.
