Self-sustaining, self-contained systems and methods for producing biofuels and for producing biofuel feedstock from algae. The system is carbon neutral or may be carbon positive, fixing more carbon than it releases to the atmosphere. In various embodiments, the system may be coupled to an existing carbon dioxide producing process to reduce or completely eliminate carbon dioxide output, making the existing system carbon neutral, and providing valuable and tradable carbon credits. The system may also comprise modular tiles comprising a biomass sandwiched between two panels and use a combination of microbes, nutrients, water, and sunlight to generate biological hydrocarbon compounds that can be used in almost any type of engine.

Unique engines, air compressors, and pneumatically driven electrical generators are disclosed. The engine employs a rotor having a number of pistons slidably disposed within respective cylinder bores extending into the rotor periphery. As the rotor spins within a stator, each cylinder bore passes a combustion stage at which the piston is driven further into the rotor toward a bottom of the respective cylinder bore. Valves at the bottom of the cylinder discharge air that is compressed by this piston downstroke, and admit new intake air during an opposing upstroke. The unit thus operates as a self driven compressor, or engine-compressor combination, and the compressed air may be used to pneumatically drive a turbine of an electrical generator. A carbon splitter dissociates carbon and oxygen molecules from the carbon dioxide in the air downstream of the generator turbine, reducing the overall carbon dioxide output of the system.
