 '''Algae''' are a diverse group of organisms, ranging from ten meter long kelp to [[microbes|unicellular]] dinoflagellate. These organisms are a vital link in many food chains on [[Earth]]. The farming of algae is called [[algaculture]].

-In the right climate on Earth, algae farms can produce 100 tonnes per hectare of biomass. <ref>http://franke.uchicago.edu/bigproblems/Team1-1209.pdf</ref> This compares to about 80 tonnes per hectare for tomatoes in greenhouses, and about 5-10 tonnes per hectare for many crops such as rice, corn and wheat.  As Mars gets roughly half the sunlight Earth does, a production rate of 50 tonnes per hectare might eventually be possible.  The energy conversion rate of photosynthesis driving this production is about 3-4%.<ref>https://en.wikipedia.org/wiki/Photosynthetic_efficiency</ref>  The plant uses most of this energy to build itself and support its internal processes, so the yield of oil producing algae might be about 0,3 to 1%.  the average yield of crops is about 2% by mass and 1% of edible components.

 A large support infrastructure to produce the necessary fertilizers, clean the water, control the plants genetics, gather the algae and control the environment would be required.

-Awesome! I applaud Mr  Callega for this great dscoivery.  I wish our leaders would take up this challenge and make our environment really cleaner with these algae streetlight, or at least start a pilot in some of our biggest cities.
