Brazilian Formula E champ @LucasdiGrassi is building much safer far-UVC sterilizers & donating them to local hospitals. On a robot they could disinfect public bathrooms, schools, shops & airports... https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Clapping hands sign" aria-label="Emoji: Clapping hands sign"> @roborace @elonmusk @iRobot @BostonDynamics

The study @scientific reports conducted by @Columbia Medical Center showed far-UVC light destroys aerosolized H1N1 influenza particles https://abs.twimg.com/emoji/v2/... draggable="false" alt="🦠" title="Microbe" aria-label="Emoji: Microbe">...

Scientists have known for decades that UV light is highly effective at destroying viruses by destroying their DNA & RNA https://abs.twimg.com/emoji/v2/... draggable="false" alt="🧬" title="DNA" aria-label="Emoji: DNA">. However, its widespread use is limited because conventional UVC can cause skin cancer & cataracts...

Far-UVC light at 222 nm can penetrate air droplets (e.g. from a cough) but NOT the outer dead-cell layer of human skin https://abs.twimg.com/emoji/v2/... draggable="false" alt="🖐" title="Raised hand with fingers splayed" aria-label="Emoji: Raised hand with fingers splayed"> or water covering the eye https://abs.twimg.com/emoji/v2/... draggable="false" alt="👁" title="Eye" aria-label="Emoji: Eye">, so it’s much less a health hazard. But because viruses https://abs.twimg.com/emoji/v2/... draggable="false" alt="🦠" title="Microbe" aria-label="Emoji: Microbe"> are much smaller than human cells, far-UVC can destroy them...

The scientists show how far-UVC could be used to safely sterilize air and surfaces in planes, cruise ships and buildings...https://abs.twimg.com/emoji/v2/... draggable="false" alt="✈️" title="Airplane" aria-label="Emoji: Airplane"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="🏥" title="Hospital" aria-label="Emoji: Hospital"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="🛳" title="Passenger ship" aria-label="Emoji: Passenger ship"> https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Clapping hands sign" aria-label="Emoji: Clapping hands sign"> https://tinyurl.com/t227mwx ">https://tinyurl.com/t227mwx&q... @roborace #FormulaE #COVID19

The far-UVC study @Columbia was run by David Welch, an American businessman and research scientist. Welch is a pioneer in optical devices and telecom networks. He has more than 250 published articles and 125 patents. https://abs.twimg.com/emoji/v2/... draggable="false" alt="🇺🇸" title="Flag of United States" aria-label="Emoji: Flag of United States"> ingenuity https://abs.twimg.com/emoji/v2/... draggable="false" alt="👏" title="Clapping hands sign" aria-label="Emoji: Clapping hands sign">

Note: This is a prototype. Not yet far-UV but will be in later models.
