The Hongtuo Joint Laboratory in Wuhan, China, has invented a laser pen that can be used to write in the air.
The South China Morning Post reported yesterday that the pen uses lasers to strip air particles of their electrons and turn them into light-emitting plasms.
According to the Science and Technology Daily, the lab lead scientist said that they could draw in the air without using paper and ink.
Scientists said they used 3D scanning to create Chinese characters, but didn't explain how the process works. It sounds great, but we need to see more in the way of a demo.
The pen works in very short laser bursts. Its power output is hard to comprehend.
The total amount of power the United States can generate is greater than the one million megawatt laser pen's output. Scientists say that the device is relatively safe because it doesn't draw a lot of power.
The pen could one day be used in advanced tech. Maybe we will see some new technology.
China accuses the United States of encroaching on outer space.
