For many folks, the use of solar panels to generate electricity is a recent technological development. When some think of photovoltaic (PV) solar panels, images of early NASA vehicles in outer space might immediately come to mind. Indeed, America’s first permanent satellite, Explorer I, was powered by PV panels in 1958.
However, the use of solar energy dates back to 1767 when a Swiss scientist named Horace-Benedict de Saussure built an insulated, glass-faced box, generating temperatures of up to 230 degrees from sunlight. His invention was dubbed the “solar oven.”
Thirty-eight million. That is how many Americans will be digging around buried utility lines this year, according to a recent survey by the Common Ground Alliance. They found that nearly half of American home owners who plan to dig for projects like landscaping, installing a fence or mailbox, or building a deck, pond or patio, will put themselves at risk by not calling 811 a few days before hand to learn the approximate location of underground utilities.
