And remember, @CDCgov already concluded in systematic review of 14 RCTs that masks don't mitigate influenza spread, and a meta analysis further evidenced that even N95 masks make no difference vs cloth masks, meaning that no masks - not even N95 - workhttps://t.co/mSwdz7U6tM

As if they didn't know this before or conclude CONSISTENTLY after systematic review + meta analysis of randomized controlled trials that masks do not mitigate communicable viral spread?
But TRASH "health" agencies & experts continue w/their Wear A Mask campaign & suppress niacin

Charting early steps for H₂ infrastructure in Europe.
👉Summary of conclusions of a new study by @AgoraEW @AFRY_global @Ma_Deutsch @gnievchenko (1/17)
https://t.co/YA50FA57Em
The idea behind this study is that future hydrogen demand is highly uncertain and we don’t want to spend tens of billions of euros to repurpose a network which won’t be needed. For instance, hydrogen in ground transport is a hotly debated topic https://t.co/RlnqDYVzpr (2/17)
Similar things can be said about heat. 40% of today’s industrial natural gas use in the EU goes to heat below 100°C and therefore is within range of electric heat pumps – whose performance factors far exceed 100%. (3/17)
Even for higher temperatures, a range of power-to-heat (PtH) options can be more energy-efficient than hydrogen and should be considered first. Available PtH technologies can cover all temperature levels needed in industrial production (e.g. electric arc furnace: 3500°C). (4/17)
In our view, hydrogen use for feedstock and chemical reactions is the only inescapable source of industrial hydrogen demand in Europe that does not lend itself to electrification. Examples include ammonia, steel, and petrochemical industries. (5/17)
