with his friends invented an innovative bird feeder that worked on solar power. The feeder used a small solar panel in its roof to build an electric charge. The Solar feeder’s purpose is to use the mild electric shock it generates to repel the squirrels‚ preventing them from stealing the bird seed or damaging the feeder itself. In a typical product-driven approach‚ Bo and his friends started SDI‚ Inc. to produce and promote the solar feeder without having done any marketing plan. After several years

hat can be produced from domestic resources. Although not widely used today as a transportation fuel‚ government and industry research and development are working toward the goal of clean‚ economical‚ and safe hydrogen production and hydrogen fuel cell vehicles. Hydrogen is the simplest and most abundant element in the universe. At Earthsurface temperatures and pressures‚ it is a colorless‚ odorless gas (H2 ). However‚ hydrogen is rarely found alone in nature. It is usually bonded with other elements
