Some (ofter traditional) experts maintain transmission is through larger droplets (propelled while sneezing etc.) and contaminated surfaces.
I think a 2nd and growing group of experts has the evidence to prove it's also (and probably largely) aerosols. technologyreview.com/2020/10/02/100…
What does this mean?
It means you get it from inhaling the air that's exhaled by infected ppl.
When are you at risk?
Imagine persons around you are smoking. Would you breathe in lots of their exhaled smoke? Not safe. Go outside.
Talking/shouting/singing makes it much worse.
By the way: that aerosols play a role and thus that ventilation and masks are important (even when keeping distance) is hotly debated. This study even goes into how this 'disinformation that masks help' spreads like a virus. researchopenworld.com/how-misinforma…
But I think the previous publication is flawed and looking only to disqualify the 'heretics' arguing that aerosols play an important role too.
If only out of an abundance of caution I think we should take both groups of experts seriously.
Btw: face masks are mandatory in France and Spain. So I should probably have used more words in my first tweet.
The point I want to make is that we should take the second group of experts (pointing to aerosols) serious. This also means wearing masks. And yes I hate them too.

GEOTHERMAL
Just saw a fascinating webinar and you should too if geothermal interests you.
It explains how techniques from fracking are creating a game-changer in the last few years that can reduce the cost of energy systems without fossil fuels.
🧵
The webinar by prof. Roland Horne from @Stanford is about Enhanced Geothermal Systems or EGS that he defines as using fracking to make the area between the infusion and extraction well permeable for water.
He focuses on @fervoenergy, a company founded by two @Stanford alumni (one from his program) that has for the first time in history used the horizontal boring technique from fracking in geothermal.
This eviscerates the last credibility of @Toyota regarding EVs.
They (esp. Gill Pratt) have been pushing the story we should buy their hybrids instead of full EVs because lithium batteries are and will stay the bottleneck
