“Researchers have developed systems that can automatically sense and blend into their surroundings by mimicking the methods of cephalopods such as octopus, squid and cuttlefish.
And the “optoelectronic camouflage” works stupendously just as long as it’s situated directly in front of a zebra.
So far, the scientists have only built a one-inch square prototype that works in black, white and shades in between, sort of like your grandfather’s TV. But the systems can be scaled up and made to work across the color spectrum, according to a statement from Cunjiang Yu, assistant professor of mechanical engineering at the University of Houston and lead author of the paper published this week in the Proceedings of the National Academy of Sciences.”
Hassani, a product designer from Afganistan, build (by hand) a wind-powered device that trips land mines as it rolls across the ground. It is made using bamboo and biodegradable products.
Many of these mines are active and near populated areas in countries like Afganistan and are hard to remove. The UN says that one mine clearance specialist is killed, and two injured, for every 5,000 mines cleared.
Hassani’s cheap and easy to make method has been achieving great results.
