RIVERS HYDRO POWER

The River Hydro Power turbine was created by Smart-Hydro to harness the kinetic energy of moving water to generate the most electrical power possible.

It is dubbed a ‘zero-head’ or ‘in-stream’ turbine because it is propelled by kinetic energy rather than potential energy. As a result, no dams or head differential are needed for the functioning of this device. A river's natural path is maintained, and no infrastructure investment is needed (other than the turbine).

The quantity of kinetic energy differs between rivers, with a higher velocity of water flow producing more energy.

These renewable energy systems can produce electricity at power levels of up to 5000 W. The floating body of the turbine is made up of a three-piece diffusor and two floats, together with a generator and rotor with three blades.

These turbines may be erected in the riverbed or canal bed; indeed, they are very appropriate for installation in canals. A river or canal must be 2 meters deep, 3 meters wide, and have a minimum velocity of 1.2 meters per second in order to function. The system just needs routine cleaning, no technical operations or maintenance.

For private owners or for small villages or towns looking to go off the grid, this is the easy choice!

WHEN CITIES SPONGE THE WATER!

Climate change isn't very good at moderation. A warmer atmosphere retains more moisture, supercharging storms to drop more water more quickly. This can overwhelm city sewage systems, designed for a climate from long-ago.

So, you have biblical deluges that have been drowning cities all over the globe, from Zhengzhou, China, to Seoul, South Korea, to Cologne, Germany, to New York City.

In response, urban planners are increasingly seeing cities as sponges rather than raincoats, which are designed to quickly remove water before it has a chance to build.

‘Sponge cities’ turn rain into a resource to be used rather than wasted by constructing thirsty green areas and creating enormous dirt bowls where water may collect and seep into underlying aquifers.

Where there were formerly wetlands, fields, and woods that would soak up the rain, they have been built over and replaced with hard surfaces like concrete sidewalks, asphalt roads, and roofs that channel runoff into gutters, storm drains, and sewers.

The effects of climate change are becoming greater as cities get denser and employ even more impermeable surfaces.

As the capacity of these sewage and water runoff facilities is reached, water begins to back up, and the issues it causes are made worse by the absence of significant expanses of naturally absorbent soil and plants.

Green areas are important for cities, although historically they have been mostly utilized for public pleasure.

But they are also a technique used by city planners to control the increasingly violent downpours. They call this, the ‘Sponge’.

Creating a surface out of concrete bricks that is more permeable is one method to deal with this new reality. The secret is to insert crushed stone into the tiny spaces between the blocks, allowing water to flow down between them.

Whenever there is no room for vegetation, such as in parking lots and alleyways, this form of pavement might be used.

Using a rain garden, a small area of vegetation on a property or by the side of the road that collects water runoff from the roadway, is another option. Building ‘vegetated swales,’ which are simply ditches covered with grass and other plants that collect rainwater and aid in its seepage into the earth, is yet another possibility.

For a different reason—a lack of water—Los Angeles has been installing specifically created green areas on highway medians for years.

Due to climate change, Southern California will see storms that are more violent than those that hit the East Coast, but less often. The value of large water dumps will increase as a result, and if the city can figure out how to collect them, it will be able to reduce its reliance on water imports from Northern California and the Colorado River.
