How Mirrors Could Solve our Energy Problem

Only downside is, that it needs direct sunlight, so just a couple of cloudy days will ruin the energy net. So very large and efficient heat saving crystals are needed to cover the nights and cloudy days. It would solve the energy problems in a lot of hot and dry countries with far less rare minerals and much more durable technology. This tech also can be used to produce hydrogen far more efficient than with electrolysis.
