A biodegradable drone made out of fungus, bacteria and wasp spit built by NASA-affiliated scientists may pave the way for future spyware, which would simply self-destruct if it crashes, leaving behind only minute remnants, reports RT.com.
The biological drone would simply melt away, according to its designers. “No one would know if you’d spilled some sugar water or if there’d been an airplane there,” Lynn Rothschild of NASA’s Ames Research Center in California told New Scientist. The model was conceived by a group of scientists from across Stanford, Brown and Spelman College.
The bio drone completed its first flight earlier this month at the International Genetically Engineered Machine competition in Boston. It is primarily made of a fungal material called mycelium – the vegetative part – and looks a little bit like a cardboard drinks holder.
After the main body was produced, the outer skin had to be made out of bacterial cellulose sheets, which were grown in a laboratory and take on a sticky, leathery type consistency. It was then waterproofed, but this still had to allow for its immediate biodegradability. Check out this video about it from YouTube User Dahboo77
