Indeed, but genetically engineered agriculture technology scales quickly at negligible cost. Note, people have already cultivated food-grade Spirulina for many years. Cost effectiveness is just part of an optimization problem, that will be constrained by desirable traits: temperature resistance, replication rate, and viable fuel content. In many places, uncontrolled algae blooms are already a naturally occurring issue in the run-off from large cities/farms. There are several firms already working on this biotech. Note, a algae biodiesel would solve the issues with clean efficient generation, energy density, repurposing distribution, and repurposing storage. Thus, a Goat cart is a safer bet. =)
