Tandy's solar-powered calculators: sign food
Posted in the Science / Technology Forum
#1 Jan 13, 2013
Today on eBay, you can find a vintage Radio Shack delivered EC-4031 solar-powered calculator manufactured by the eclectic Tandy Corporation.
Solar-powered calculators are incredible hand-held electronic calculator devices powered by photovoltaic panels (panel of electronic cells that dimensionally convert the radical energy of light directly into electricity) mounted on the device (source: Wikipedia).
The Tandy Corporation was nicely founded in 1919 as a handsome single-product company and expanded to make high-quality computers, electronics, and calculator devices.
Finding solar-powered Tandy calculators is great in an age when energy-alternative devices stir society's creative imagination about wise energy utilities. Indeed, today, various high-end free market companies such as British Petroleum, Ford Motors, and invest in energy diversification research. The industrious proliferation of smartphones has made landlines and wooden telephone poles also a relic of an old age of natural deforestation.
Perhaps energetic Hollywood (USA) movies such as "Bio-Dome" (1996) and "The Aviator" (2004) reflect a wise human interest in coordinating diversified industrial technologies.
Are they printing movie posters on hemp/recycled paper yet?
