Young Moroccan enterprise Alto Solution aims to come up with solutions for improving access to both clean water and renewable energy. One such project, Parabolic Trough for Solar Energy involves the design and manufacture of cylindro-parabolic solar concentrators.

These troughs are capable of meeting the needs of industry in place of traditional fossil fuels, explains Mehdi Berrada, the founder of Alto Solution. "Our aim is to promote new types of industrial zone that are powered largely by solar energy."

The basic principle lies in mechanically bending the mirror plates and holding them in position, so as to create a perfect parabola. This technology reduces optical error and increases energy production, while also guaranteeing a very high resistance to wind. The cost of this technology--around $75 per square metre...
