Renewable energy systems extracting energy from natural water flow or wind. The energy systems are configurations of long-stroke open-channel reciprocating engines employing one or two flow engaging elements such as drogue chutes for water flow or airfoils for wind applications tethered to a power drum and useful to generate electricity or to pump water as from wells. A wind energy system using two buoyant airfoils emblazoned with advertising messages is suitable for urban deployment generating electric power and also supporting an advertising revenue stream.

Why it's free to use
- Filed September 17, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 17, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 17, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
