Disco Defense
Farmers in northern Botswana may soon be protected from elephant raids on their crops by a novel technique that also keeps humans dancing around the world.
Researchers near Chobe National Park installed lines of solar-powered, multi-colored strobe lights around crops and found they repelled elephant incursions by 75% compared to areas without the lights. The disco-themed LEDs were placed on poles every 33 feet and constantly flashed a different color — red, green, amber, white, blue or yellow. The color patterns were changed every week to prevent the pachyderms from getting used to them.
