Feasibility model for two-axis solar tracker

2-axis solar tracker: Feasibility model

Full-size, two-axis solar tracker

2-axis solar tracker: Full-size unit


Successful testing of the feasibility model was followed by construction of the full-size two-axis solar tracker, which requires less than 10 watts to drive it, produces 2 kilowatts of heat energy, and heats 100 gallons of 55°F tap water to 155°F in 8 hours of daylight. (Patent No. 4,202,321)

Two solar stills

Solar still for desalinzation of sea water


Behind the control console are two 8 x 12 ft. solar stills, each of which alone desalinizes 18 gallons of salt water on an October day
