I like how some of the shots hint at future possibility of improvement. * The inside connection from the blower to the tuyere was a sharp transition. Perhaps it could be smoothed to reduce back-pressure. * Poor ergonomics for spinning the rotor (mentioned near the end of the video). Might be improved by having a longer central shaft for the rotor, so it could be operated while standing.
