Editing Tyson turbine

[[File:Animatic of a tyson turbine rotating in a flow.webm|thumb|Animatic of a tyson turbine rotating in a flow]]
The '''Tyson turbine''' is a conical [[water turbine]] with [[helix|helical]] blades emerging partway down from the [[Apex (geometry)|apex]] gradually increasing in radial dimension and decreasing in pitch as they [[spiral]] towards the base of the cone. This design doesn't need a casement, as it is inserted directly into flowing water.<ref>{{cite patent

Marketed as part of a [[hydropower]] system that extracts power from the flow of water, the turbine is mounted below a [[raft]], driving a power system, typically a [[lift irrigation]] [[pump]] or [[generator (device)|generator]], on top of the raft by belt or gear.<ref>{{cite conference
