The Reactant Dynamo is a block added by Thermal Expansion 4. It is used to generate Redstone Flux (RF).



The Reactant Dynamo produces energy from a fluid fuel and a reactant like gunpowder. This rate will decrease based on how full the internal tank is unless there is a Excitation Field Limiter augment installed.

To change the orientation of the dynamo, use a Crescent Hammer.
