Brian May is developing a new ventilation system for concert halls and similar areas.

The Queen guitarist was recently at the Apollo Theater in London to test the system he devised.

May announced on Instagram on Wednesday that he recently woke up with an idea for such a system.

"An airflow system to make theaters safe enough again in a pandemic situation and to make concerts take place again, just like before," writes the 73-year-old guitarist, who was promoted to astrophysicist in 2007 and also studied chemistry and mathematics.

The Queen guitarist sat down with three experts and together they studied the current ventilation system in the Apollo Theater and also tested some theories.

The artist does not share what his devised system looks like.

"We are still at an early stage and there are still major problems for which we have to find a solution. But even if we partially succeed in this, it can be a step to resume concerts."

May and his Queen colleagues were due to tour Europe this year.

These shows have been provisionally moved to 2021 due to the corona virus.
