Clean Energy Infrastructure

Clean Energy Infrastructure

E.Ray offers energy, telecommunication and hydrometric data services through a single platform under an infrastructure as a service model.

Long Description

e.Ray’s hydrokinetic turbines and solar home systems that are the foundation of countryside infrastructure for 3 major needs:

  1. Telecommunication
  2. Flood warning
  3. Clean energy


  • Energy: e.Ray’s floating turbine uses flowing water to generate electricity. Each turbine can generate enough electricity to power hydrological sensors and the telecommunication infrastructure and provide electricity to several households.
  • Telecommunication: Provide internet access and communication services in the same rural and remote villages which get their electricity from e.Ray’s turbine and otherwise lack access to communication networks. This data link will then be used to transfer the hydrological data collected.
  • Hydrological data: e.Ray’s turbine serve as a platform for different sensors which collect information on velocity and water levels. These serve as inputs for flooding models and flood warnings. Multiple additional sensors can be installed along the same river and connected with the turbine through a local LPWAN network. The turbine will act as a central hub and transfer all the hydrological data from the dispersed sensors to the final users in the large cities via the 3rd party telecommunication link.

Through the integration of these three essential services, each of them can be delivered at a price level affordable for the remotest and poorest communities, without its government spending large amounts of capital to roll out separate infrastructure on a national scale.

The need for any of these three services offers an opportunity for the other services to be deployed as well.
