- amount saved by producing locally (transport is 3/4th of real material/energy cost of existig material production)

great one, and if coupled with sourcing materials locally (like biomass/algae for biodegradable filaments for 3d printers), tremendous potential

- use of debt-free funding (reduces cost by 52% according to Margrit Kennedy)

Do you have any reference for this? Would like some reading here. Thanks
