Algae biodiesel could be put in regular trucks, is carbon neutral, and uses existing infrastructure. Additionally, Algae will be the only thing robust enough to survive >50'C temperatures, as hot lithium batteries also start to have issues.
Hydrogen has poor energy density (needs very large storage volumes), is expensive to handle safely, and still hits the equivalent of $13/l for petroleum gas. The field trials already profiled the degenerative nature of fuel cells, and problems with Hydrogen embrittlement.
I wager Goat Carts are the future, as most civilizations had them in their past. They are also far more radiation tolerant than primates. =)
- tim333 3y agoAlgae biodiesel has so far, I think, been nowhere near cost effective.
- Joel_Mckay 3y agoIndeed, 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. =)
