The sun has long fascinated scientists. It’s immense power keeps the globe alive and as long as there is a planet earth there will be solar energy.
Dr Eduardo Zarza Moya has been studying solar energy for more than 20 years and in this interview he delineates the technology involved in solar concentration and its potential. Using large scale mirrors to harness solar radiation in order to produce steam, which then drives electricity turbines, solar concentration is a clean process reliant on the sort of solar radiation apparent in the hottest parts of the planet. Dr Moya is currently involved in a project to build a solar energy plant in North Africa and while he admits transmitting the electricity produced is currently prohibitively expensive he remains positive about the future.

Renewable energy has been both praised and derided as an alternative source of power over the past two decades. To its detractors it is inefficient, unreliable and economically unsound. To its advocates it is free, clean, and unlimited in its potential. With global reliance on dwindling oil reserves an international political priority, attention continues to focus on renewable energy and its applications.
This month’s Comment Visions examines the developments in renewable energy by talking to a man whose work harnesses the power of the sun to produce cooling technology. Dr Ahmet Lokurlu is a Turkish engineer and scientist whose company produces air conditioning systems run by solar power. Generating energy from the sun and turning it into cold air in countries where fuel-hungry air conditioning accounts for more than 40% of totally energy use vividly demonstrates the innovative solutions renewable sources can provide.
