NSFW    SAN ANTONIO, TEXAS — "Virus-killing robot zaps viruses at airport!" shouts the Washington Post headline.

While this headline is clearly intended to catch attention, the reality is very different.

Firstly, one has to chuckle at a news outlet that calls a light that has to be pushed around on a wheeled trolley, a robot.

However, once we understand that this is clearly not a robot, we can appreciate the powerful technology that this device does represent.

The coronavirus scare has prompted airports to come up with innovative gadgets designed to combat the virus.

San Antonio International Airport in Texas has opted for a germ-zapping device called a LightStrike.

The device is 1,1 meter tall and has to be pushed around by an operator to reach targeted areas.

The high-tech plug-in pushcart uses powerful bursts of ultraviolet light to kill viruses on surfaces within a 2,1 meter radius in every direction.

Most UV devices use low-intensity mercury bulbs, which means they may take longer

to kill organic material such as viruses. By contrast, LightStrike has a powerful xenon UV-C light source capable of damaging the DNA and RNA of viruses in a matter of minutes.

The light bursts are so powerful that the operator has to move away before the device starts to pulse its deadly rays.

That's why the virus zapper also has motion sensors, allowing it to switch off when it senses humans coming too close.

When plugged in, the machine stores up a charge and releases the UV light in quick, pulsating bursts.
