Around the global south, cities struggle to provide electricity and energy to all their residents, and unsurprisingly, the poorest residents are most likely to remain disconnected from formal power systems. Many of the same cities also face an immense garbage challenge: what to do with overwhelming amounts of unsanitary and even toxic waste.
Algae is everywhere, it grows easily, and it's full of lipids that, when successfully extracted, have the perfect chemical makeup to be transformed into hydrocarbon fuel. The trick, as always, is to do the processing in a cost-effective and cost-efficient way, a goal that has been elusive so far. Enter Nevada-based Algae Systems.
The effort to produce algae biofuels has been underway for many, many years, though you wouldn't know it given that there are still virtually none being produced at commercial scale. The hype about making "cheap, abundant fuels with nothing but sunlight and water" remains in spite of the reality on the ground.
