I used to buy flaxseed oil as a cheap source of omega 3. Then someone on HN informed me that it has crappy bioavailability. So, I switched to fish oil.

Free business idea: stop trying to make biodiesel and instead harvest omega 3 from algae. Sell it to the whole world at $8/gallon. Make the world a smarter, calmer place in the process.

Where does the algae come from?

If it comes from mercury- or other toxin-laden areas, the omega-3 may cross the blood-brain barrier and deposit whatever it's laden with in the brain.

People are farming algae in isolated environments to eventually make diesel. Seems more direct, higher-margin (lower volume, admittedly) and more ethical to squeeze healthy edible oil out of the algae instead.
