Run-of-river hydropower facilities can generate electricity by placing a small, mini-, or micro-turbine into a waterway, and do not necessarily require the construction of a large dam. Some hydropower turbine technologies do not need dams to operate, if the flow of water is large enough to turn the turbine.

The current study proposes a new strategy for using small hydroelectric turbines in downstream river branches with the least amount of construction and the
Due to its better performance, even at partial loads, the cross-flow turbine is well-suited to stand-alone electricity generation. It is mainly used in small-hydro power units for small run-of-the-river schemes, as the flow rate in small rivers which varies seasonally [30]. 2.1.2. Francis turbines
The current of the Mississippi River flows past New Orleans at around 4 mph (6 kmh) at times, according to data from the U.S. Army Corps of Engineers. Since moving water can produce 800 times more
Return of water to the river: After passing through the turbines, the water is returned to the river via a tailrace. This minimizes the impact on the local ecosystem and maintains the river''s natural flow. Run-of-river hydroelectric plants are relatively simple to operate, with fewer components and infrastructure than large dams.
A small steam turbine is a compact and efficient device that converts steam energy into mechanical power. It is commonly used in various applications, such as power generation, industrial processes, and even in small-scale power plants spite its size, a small steam turbine can still generate a significant amount of power, making it a
The turbine''s technological advantages. The motion control technology used by the DDMotion River turbine offers several benefits over current turbine designs. The speed converter transforms the variable input speed from the river into a constant output speed. There is no need for clutches, belts, pulleys or hydraulics, and power
The batteries recharge 24 hours a day, and from there, an inverter transforms the direct current (24-48 V DC) into alternating current (120 V AC) to power electrical devices. Idénergie''s river turbine can meet the electric needs of a residence by generating, at maximum capacity, up to 12 kWh daily, depending on the water velocity
9. Tyson Turbine. A variation of the traditional water wheel, the Tyson turbine is a modern adaptation that allows for more efficient energy capture in low head sites without significant environmental disturbances, often used in small scale and micro hydro installations. 10. Gorlov Helical Turbine.
A critical review focused particularly on run-of-river hydropower plant design models was carried out. Several calculation models including diameter and thickness of a penstock, admissible suction head of a turbine, and cost and energy production estimation for grid-connected applications are collected and analyzed.
This paper presents a deep and critical review of the design of micro hydro-generation technologies for river applications. This article shows three principal aspects: design, analysis and computational tools to study vertical micro-turbines, including the ones that are not vertical but that are relevant for the actual research.

Three variants of impellers for free-flow hydroelectric power plants are proposed with a comparison of the efficien-cy of each variant. An analysis was carried out
Abstract. Despite a lot of optimism about the potential of hydrokinetic turbines in rivers, the reality is that very few are currently deployed in rivers, delivering power to those who need it. Barriers to their widespread deployment include, above all, the cost per kW actually delivered in rivers which rarely flow at more than about 1 m/s, far
Portable river turbine can power your house by generating 12 kWh daily. Perhaps best of all, it''s a straightforward solution which — to use an oft-repeated Silicon Valley buzzword
Generally, a small-scale hydropower plant works on the run-off-river system. This type of system requires no water storage, instead, canals or diversion are required to have constant flow throughout the year. Low-head turbines are designed for rivers or canals where there is a small head but sufficient flow to provide adequate
The WaterLily Turbine is bulkier and takes a little more effort to use than solar chargers, though after getting acquainted with it, the turbine adds a good amount of power generating versatility, as well as a 24-hour energy source, to those who carry it. It''s great for setting up and attaching a power bank or device to overnight and waking up

Benefits of Small-Scale Wind Turbines. 1. Energy Independence. Small-scale wind turbines empower communities to generate their own electricity, reducing dependence on centralized power grids. This energy independence can be crucial during power outages, emergencies, or in remote areas where grid access is limited. 2.
The axial-flow (horizontal axis) and cross-flow (vertical axis and in-plane) turbines are the most commonly used small-scale HKTs (Vermaak et al., 2014). Numerous companies around the world are now developing hydrokinetic turbines to harvest tidal and river flows, but there are four major problems with most designs for rivers: (i)
