Former Fiat engineer aims to put the brakes on Covid-19

Fifty years ago he designed a braking system that helped reduce fatal car crashes. Now Mario Palazzetti has invented a device he hopes will curb the spread of Covid-19.

The retired Fiat Research Centre engineer is known as Mr ABS for the anti-lock braking system he created that is now standard in most motor vehicles.

At the age of 84, he has devised a gadget about the size of an electric kettle which creates local air currents that aim to stop the circulation of tiny droplets expelled when people speak - potentially hindering the spread of Covid-19 infections.

"We've called it the Biostopper and it is used to create an aerodynamic field  so that all the breath someone emits when talking comes back to them," he explained.

Palazzetti started work on the device two months ago, hoping to address the difficulties of social distancing in schools, offices, bars and restaurants as the pandemic that has killed more than 576,000 people around the world took hold.

He is now working with a team at the Politecnico di Torino (University of Turin) to fine tune and test the product.

"I can't tell you so many technical details because we are still in the patenting phase," Professor Marco Simonetti of the Politecnico's energy department told Reuters.

"The concept is simple. The ambition is not to kill the virus, but to safely reduce the distance (between people)," he said.

The Biostopper was initially designed to allow two people to get closer together, but Simonetti said it could work for small groups.

"We are concentrating on talking because with sneezing we would need a much more invasive system," he said.

The Politecnico team hopes to have a prototype by the end of July and to go to market by the end of the Europea summer.

Mr ABS, who retired in 1997, is behind other inventions, including the TOTEM (Total Energy Module), a small heat and power generator, and an air-conditioning system called Aircare, which also recovers energy.

"The ideas come to me, it's not like I'm thinking," he said.

"My regret is that I have a lot of ideas that are asking to be brought to light, but it's really difficult."
