COHESION BASED HYDROELECTRIC POWER

NºPublicación: WO2019051580A1 21/03/2019

Solicitante:

FERENCZY MIKLOS [CA]

CA_2978935_A1

Resumen de: WO2019051580A1

Cohesion based hydroelectric power invention represents generation method eliminating: o substantial water-head o large-dam construction o environmental and visual concerns. The dominant vertical drop from the usual position between the water intake and turbine (penstock) is relocated by this invention to between the turbine and the water outflow, utilizing this way water-cohesion-forces in cohesion-pipes positioned after the turbine, allowing substantial - at will - water velocity increase in the penstock. Multiple level energy generation increase is achieved with reduced water volume intake. This invention substantially reduces time and financial requirements of new, renewable hydroelectric-power-station construction. Hydroelectric-stations may be constructed at locations previously considered nonappropriate, where limited - but still satisfactory - water supply is available. Upgrading existing hydroelectric-power-stations (dammed, pumped, ROR, etc.), or non-powered dams is possible to increase generating capacity while reducing water volume requirement and environmental impact.
