Pond scum or pond scam?

If you look at current factory gate prices ($ 5 - 10 per kg), algae are way too expensive for low price applications such as biofuels and CO2 mitigation.
The often cited yield projections are pure fantasy. The reality is that ponds yield about the same amount of biomass as tropical agriculture. The difference is that sugarcane can be cut and pressed easily, while algae have to harvested by flotation, centrifugation, and drying.
Good for the people who get a job for a while, good for the managers who pay themselves a nice salary and bonuses, bad for the investor. Put the funds in wind and solar.
