Soalr Island - Largescale electricity production
Solar Island concept is developed by a group of Swiss Scientists in Neuchâtel, Switzerland. The Solar Island is an artificial circular island of potentially large dimensions (up to 6km diameter). It consists of an outer torus and a PVC membrane platform, on which solar panels are placed. A small overpressure is applied below the membrane to compensate for the load of the solar panels. The island floats on water and slowly rotates to track the sun’s azimuth movement. The rotational tracking maintains the exact angle of mirror-panels to sun for concentrating large amount of sunlight to pipes containing water. Mirror-panels are made of long strips of inexpensive mirrors, installed in Fresnel configuration, so that each mirror strip individually focuses sunlight to the target pipe containing water. Thus the concentration of sunlight converts the water in the pipes to steam at 250°C which could run turbines to produce electricity.
The benefits of Solar Island concept over other solar thermal concentration methods is that it could provide several hundered percent cost savings and improve efficiency.
Solarberg LTD has the mandate to introduce this technology to Pakistan. This technology has the potential to profoundly contribute in Pakistan's future energy needs.

Prototype Solar Island
A first prototype of Solar Island design is under construction in Ras Al Khaimah in the United Arab Emirates. It is a land based version constructed on desert. The outer torus of the Solar Island floats on a specially constructed trench. It has a diameter of 100 meters and could produce energy equivalent to 1 Megawatt/h.
