Dessert land & aqua culture.

 

Growing of seaweed & algae in open ponds. (low tech solutions & for a better world.)

 

 

Environmental problems like climate changes, the rising sea level and the decreasing amount of fresh water force us to consider possible solutions including the cultivation of salty greens and seaweed & algae..

Desert land can be used for the growing of sea greens & seaweeds.

 

In 1990, Sheehan's NREL program calculated that just  15,000 square miles of desert (the Sonoran desert in California and  Arizona is more than eight times that size) could grow enough algae  to replace nearly all of the US current diesel requirements. Draw attention to the fact that the suns energy at the desserts is much higher than elsewhere and  the resulting harvest in seaweed/algae  higher than in most other places (Competitive advantage)                                 

Agae & seaweed need for their growth sunlight, carbon-dioxide and water.

They can therefore be cultivated in open ponds & lakes.

Depth:

Sun light travels with a different speed through water. Vertical zonation of macro algae are the result of the change of  the characteristic of light regime with depth.

Type of :  algae/depths.                                                                                                                         All marine plants near the salt water surface in fact receive more light than they require, and therefore need protection from too  much light at any wavelength. The pigment composition important  in coping with differences in total amount of light received at  different depths. Wit other words; under low light conditions macro algae put more energy into pigment synthesis than under high light  conditions.

Ponds:

The real challenge with a pond is that most of the species of algae with

the highest oil content are not the quickest to reproduce.  

For this reason, the number of species that have been successfully

cultivated for a given purpose in an open system is relatively small.

In addition, in open systems there is limited control over water

temperature, salt concentration & lighting conditions.

The benefits of this type of system are that it is one of the cheaper ones to produce –at the most basic you only need to dig a trench & pond or dike.

Many pounds do use sea greens like sea lettuce because they are not

critical; salt concentration, temperature and reproduction.

Fuel is only one aspect of the use of algae/seaweed. Seaweed is primarily a source of food, (first part of our food chain) used as fodder, in cosmetics  and used to produce pharmaceuticals/medicine and fine chemicals.
