Energy Globe Award

With more than 182 participating countries and over 2000 project submissions annually the Energy Globe Award is today's most prestigious environmental prize worldwide. It distinguishes projects regionally, nationally and globally that conserve resources such as energy or utilize renewable or emission-free sources. Award ceremonies are held all over the world. Prominent personalities as well as Energy Globe Ambassadors in 90 countries support the mission of Energy Globe. The activities of Energy Globe attract worldwide media attention - international TV stations report each year with approximately 1,000 hours of broadcasting time. The aim of the Energy Globe is to raise global attention on sustainable, everywhere applicable environmental solutions and to motivate people to also become active in this area.

Innovative technology for cyanobacterial bloom control

The project focuses on detection and control of cyanobacteria in freshwater systems. The primary goal of the project is to demonstrate the operation of two robotic vessels in two freshwater bodies with a different pattern of cyanobacteria occurrence. These vessels have enabled an early online detection and differentiation of cyanobacteria from the rest of the phytoplankton in the water so as to prevent its proliferation.

Initial situation
Despite the efforts invested into measures like prevention and treatment of point and dispersed wastewater discharges, the eutrophication of freshwater bodies still continues. One of the unwanted consequences of eutrophic water state is the occurrence of excessive proliferation of cyanobacteria or blue-green algae in warm, slow-running water, referred to as cyanobacterial blooms.. Cyanobacteria pose threats on human health by causing acute and chronic hepatotoxicity.

Solution
The solution is to develop the technology for the in-situ detection of phytoplankton and simultaneous in- lake harmful cyanobacterial bloom. Two robotic vessels Stop CyanoBloom 1 and 2 have been constructed and tested during the 42-months project duration. With the assistance of skilled architects the scientists have built a docking house for the robotic vessel that blends into the natural environment of the pond.

Innovation
The main innovation of the proposed technological solution in the project is based on the scientific finding, that final cyanobacteria bloom collapse base on cyanophages induced lysis. In a waterbody, cyanobacteria reduction results in increased biodiversity, reduced turbidity of water and positive impact on inter- specific relations between different ecological groups. The project enables the continuous flow chamber for measuring fluorometric and other water parameters.
