The first partial flow (16) is partially evaporated with heat from a heat source (20), and the second partial flow with heat from a working substance flow (11) with a low surface , tension. The two partial flows are then combined and produce a gaseous working substance flow , (10) with heat from the heat source (20). The surface tension of said gaseous flow is reduced and , the energy thereof converted into a usable form. The working substance flow (11) with a low , surface …

Why it's free to use
- Filed July 7, 2004 and granted September 24, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 7, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 7, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
