The bioHearth was developed by Richard Woods, owner of Albany Woodworks by iterating smaller scale gasifiers that used residues from the woodworks.

The bioHearth is a down-draft gasifier designed to convert clean residues (sawmill, agricultural, forestry waste) into heat an power.
They currently have a 200kW unit available that will process up to 400/lb of fuel stock per hour, and they are in the process of developing 500kW and 1 MW unit.
