Not free energy. Generation adds resistance.

Specs and assumptions

Source: attached Kingsmith WR3L product snapshots (listing claims). Everything else is a labelled model assumption. 900 mm is seat travel. Assumed handle path is 1.35 m; the solver’s working length is 1.20 m strap payout at the pulley. 40 kg @ 28 SPM is a force claim, not watts. The dynamo is direct-drive on the impeller shaft (same angle, no extra gearing).

Keys and capture

1–5 isolate subsystems, 0 assembled, H/S/T cameras, space play, R reset. Orbit drag, pinch/zoom. Auto-tour yields on input and resumes after 25 s. window.DynamoRower.render(t) is seekable. See design/dynamo-rower/CAPTURE.md.
