How Mirrors Could Solve our Energy Problem

These use fossil fuels to heat up to temperature in the morning (natural gas).  It takes more natural gas to start these in the morning than it would to produce the same amount of energy burning natural gas continuously 24/7.  So it actually wastes energy.  The amount of solar energy doesn't compensate for the waste of fuel.  These are a lie just like most, if not all, green tech power.  You failed at physics, girl.
