While the dry, sunny weather we've been getting in recent years isn't great for our water supply - it could theoretically be a boost for solar power.

A panel of experts will tackle these questions at the Crawford Family Forum tonight

One of these panelists is Harry Atwater. He's the Howard Hughes Professor of Applied Physics and Materials Science at the California Institute of Technology.
