EcoVida is an Israeli-based CleanTech company and offers a significant reduction of chlorine usage in water treatment and sanitation. EcoVida saves money by reducing chlorine consumption. The new EcoVida technology is based on patented disinfectant-related technology that leads to a significant (up to 50%) reduction in the amount of chlorine consumed during the disinfecting of water.

1. The main principle of Mechanical Vapor Recompression (MVR) is a direct compression of the evaporated vapor to higher pressure thus temperature so it can recycle energy for the heating process in the Evaporator which results is a low consumption of energy. 2. MVR is a distillation process where evaporation of sea or brackish water is obtained by the application of heat delivered by compressed vapor. The MVR system is an energy efficient solution since only 50KWH of electric power per ton of fresh water is required which is merely 5% of required energy for boiling water.

The present invention is a substrate geometry for 3D photovoltaic fabrication with an electrode geometry that is robust against defects in lithography so as to allow less expensive patterning approaches. The thin film photovoltaic device has an outer semiconductor disposed to receive light and first and second contacts disposed in different layers with an insulator between the contacts.

This invention allow flat mirror elements to be easily fabricated and efficiently packaged and shipped to field sites and assembled into the parabolic trough concentrators with potentially substantial costs reductions compared with conventional methods. The mirror is formed from a thin flat very flexible metal sheet with a highly reflective surface. Attached to the rear surface of the mirror sheet is a backbone band whose figure is optimized to form the reflective sheet into a precision parabola when its two ends are pulled toward each other.

Researchers from the University of Belgrade have developed a furnace for the combustion of biomass hay bales with automatic fuel feeding which enables an efficient controlled and continuous combustion process. The system uses agricultural by-products in standard bales form from fields to create thermal energy. It can be used for the production of thermal energy only (for heating and industrial purposes) but also for the combined production of heat and electricity (CHP facilities).

The density of the rain is monitored by cloud censors.Censor activates and runs into the house. With this water censors when it starts to rain it shuts other forms of water supply.

Surface run off from the roadside are channelled into farms for banana plantation and production thus conserving water for utilization.

Piipee is a new way to save the water. Piipee can reduces up to 80% of the water used in toilet bowl.

Polymer Institute in cooperation with Water Research Institute of the Slovak Academy of Sciences have developed a highly effective composite sorbent for the removal of contaminants from water. This includes heavy metals such as As Sb Cr Cd Pb and others. The composite sorbent can be also used in wastewater treatment including wastewater from chemical and electronic industry. Contamination of water is a global problem. The presence of certain substances in water can threaten the health of the population.

An innovative unique process of utilising waste from pineapple leaf fibre to produce paper based products. Utilising raw materials from readily available abundant pineapple and other organic waste which is not only cost effective but also environmental friendly and exhibit superior properties compared to other natural fibre
