In her News Feature “Biotech’s green gold”, Emily Waltz details the ‘hype’ being propagated around emerging microalgal biofuel technologies, which often exceeds the physical and thermodynamic constraints that ultimately define their economic viability. Our calculations counter such excessive claims and demonstrate that 22 MJ m−2 d−1 solar radiation supports practical yield maxima of ∼60 to 100 kl oil ha−1 y−1 (∼6,600 to 10,800 gal ac−1 y−1) and an absolute theoretical ceiling of ∼94 to 155 kl…

TLDR
The outline for a rational approach in evaluating which algae and which algal products are the most likely to be commercially viable is provided, which permits an evaluation of which steps in the production process have the greatest effect on the final production cost of the alga or algal product.

Microalgae Mass Production Methods
TLDR
Algae biomass productivity, lipid content, and petroleum price are decisive factors in the economic viability of algae biofuels and high material cost and limited choices of algae species require more investigation.

High photosynthetic productivity of green microalga Chlorella sorokiniana
TLDR
Good photosynthetic productivity was obtained under high temperature and high light intensity conditions, when simulating the strong irradiance of the midday summer sun, and this strain appears well suited for practical application for converting CO2 present in the stack gases emitted by thermal power plants and should be feasible even during the hot summer weather.
