Bosch is currently developing a catalysis system for cars that can reduce CO2 to negligible levels. Emissions will take care of themselves. What we use as a fuel and where it comes from should be the only concern. The fact that algae can be produced entirely domestically and practically limitlessly is great. The science will get better and we can eventually get a better return of energy from producing it. And we don't necessarily need desert space to produce the stuff; it can be harvested in literally any water. We can produce it in existing landfills. IMO we already have the space and capacity, now we just need the method.
