"I doubt algae has much oil content the way soybeans or sunflower seeds do and you can squeeze cooking oil out of them. Thus are bio diesel sources"

Actually, algae have far higher "fat" content than oilseeds. That, plus their much faster growth cycle leads them to be far more productive of "bio" fat than soybeans, sunflowers, rapeseed, and others.
