This page documents the build and development of a prototype parabolic solar hot water heater with evacuated collector, solar tracking, and safety shielding. It is hoped that the heater will eventually have a payback period of less than two years. Replacing electric hot water heating by solar would save over 100 billion kWh/year, worth 11.5 billion dollars annually for 41 million American homes.
