How to grow a solar energy garden
Getting energy from the sun is a great idea. However, installing solar panels house-by-house is slow, costly and cumbersome, and downright inefficient if the goal is to bring solar to the masses. This problem troubled Paul Spencer after he built his own uber-efficient, custom solar home near Aspen, Colorado in 2004. The engineer and serial entrepreneur wondered how he could replicate his home ...
