  2. Micro hydro - Wikipedia

    en.wikipedia.org/wiki/Micro_hydro

    Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro . [ 1 ] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where ...

    en.wikipedia.org/wiki/Gravitation_water_vortex...

    A schematic presentation of a gravitation water vortex power plant, showing the turbine in yellow. The gravitation water vortex power plant is a type of micro hydro vortex turbine system which converts energy in a moving fluid to rotational energy using a low hydraulic head of 0.7–3 metres (2 ft 4 in – 9 ft 10 in).

  4. Gorlov helical turbine - Wikipedia

    en.wikipedia.org/wiki/Gorlov_helical_turbine

    The GHT is an example of damless hydro technology. The technology may potentially offer cost and environmental benefits over dam-based micro-hydro systems. Some advantages of damless hydro are that it eliminates the potential for failure of a dam, which improves public safety.

  5. Hydra (genus) - Wikipedia

    en.wikipedia.org/wiki/Hydra_(genus)

    Hydra (/ ˈ h aɪ d r ə / HY-drə) is a genus of small freshwater hydrozoans of the phylum Cnidaria.They are solitary, carnivorous jellyfishlike animals, [2] native to the temperate and tropical regions.

  6. Small hydro - Wikipedia

    en.wikipedia.org/wiki/Small_hydro

    Small hydro can be further subdivided into mini hydro, usually defined as 100 to 1,000 kilowatts (kW), and micro hydro which is 5 to 100 kW. Micro hydro is usually the application of hydroelectric power sized for smaller communities, single families or small enterprise. The smallest installations are pico hydro, below 5 kW.

  7. Low-head hydro power - Wikipedia

    en.wikipedia.org/wiki/Low-head_hydro_power

    Low-head hydro power refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. [1] Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge.

    A new study in the journal Frontiers in Toxicology found that microplastics in the fish we consume are far more widespread than you may think.. In late December, researchers from Portland State ...

  9. Water power engine - Wikipedia

    en.wikipedia.org/wiki/Water_power_engine

    Hydro power is generated when the natural force from the water's current moves a device (fan, propeller, wheel) that is pushed by the force of the water. Ordinary water weighs 8.36 lbs per gallon (1 kg per liter).
