The name reveals its function
It is called "River Hydrokinetic Turbine" and is used to produce electricity. Immersed in the current of a river or stream, through the induced movement of its blades, it is able to convert the kinetic energy of running water into electrical energy.
In short ... for some homes that have a watercourse nearby with constant water flow, it could represent a valid alternative to the photovoltaic system!
How much electricity does it produce?
Let's imagine we live in a house similar to the one in the following image:
Could our turbine be able to supply us with all the electricity we need?
Below are data extrapolated from the electricity bill of my house (Udine, Italy), where we live in two and unfortunately we do not have a river nearby:
The average annual consumption (family of 2) is about 1600 kWh. Doing a simple search on the internet we find instead that the average annual consumption of a family of 3-4 people is about 2700 kWh.
Let's analyze the production capacity of our river turbine, which logically depends on the flow rate and the speed of the water:
With a water speed of 2 m / sec, we would have an annual production of 2000 kWh per year: this production would easily cover the needs of my home (family of 2). To cover the annual needs of a family of 3/4 people (2700 kWh), 2 turbines would be enough.
In the hypothesis of living in a house near a river or a stream, the adoption of one or two hydrokinetic turbines becomes a very attractive energy solution! Surely one should "equip" for the installation and maintenance of the system... but the following images do not seem to illustrate an impossible operation:
