It has become common knowledge that humanity needs to change the sources of our energy at an unprecedented rate if we are to avoid the worst effects of climate change. Renewable energy systems are the most promising means available to reduce our impact on the earth without giving up the comforts of readily available electricity.

In this article I’ll be looking at a type of solar power plant which avoids this problem in a most ingenious way.
