How old are you that you’re even considering this? You’re unlikely to be posting here and belong to the at-risk demographic.

Also, since you believe the vaccines are valuable (otherwise you wouldn’t want a third), how do you deal with the thought that most of the world hasn't had an opportunity to get a first shot?

Sputnik V and Johnson and Johnson are not live or attenuated virus but adenovirus vaccines. They infect the host with a harmless virus that make your cell produce spike protein. They are a fairly new tech.

Also Sputnik V is a two dose vaccine, like Astra Zeneca’s

If you like RPN, try freecalc42. I got a plain 9

It implements the HP42, but with a math library w/ 34 decimal digits of precision. You can also buy a calculator, the DM-42 that runs on it and itd be the best calculator in the world if the key board weren't so… bleh

Your profit margin sets the return on investment, which must be on the tangent portfolio line or investors drop you.

Of course thats simplistic thinking, the tangent portfoglio is unknowable.

And there are other benefits of not charging the same profit margin.

But, in general, you’re going to have a bad time w/ investors if your profit margins are industry standard.

TLDR

But for teflon to passively cool, it would have to be strongly absorbent in the IR.

The way it works is this: the sun’s rays are at 5500 K. So you pick the set of materials that reflect light in the visible gap (the atmosphere takes care of the rest).

This keeps the material from getting heat.

Then, from this set, you pick a material that is strongly absorbent in IR.

If it absorbs in IR, itll emit there too, there y cooling itself
