A newly designed airplane prototype does away with noisy propellers and turbines – uses charged molecules to fly.
“Instead, it’s powered by ionic wind: charged molecules, or ions, flowing in one direction and pushing the plane in the other. That setup makes the aircraft nearly silent. Such stealth planes could be useful for monitoring environmental conditions or capturing aerial imagery without disturbing natural habitats below.
The aircraft is the first of its kind to be propelled in this way, researchers report in the Nov. 22 Nature…”
