Interesting topic. I recently got my first own car (have been driving for almost two decades, though) and started to learn about how it works in some detail. Regarding gasoline - I just found out that my car (as most cars since the 2000s) works just fine with E10 (up to 10% bio ethanol). In Germany, though, this is still a heated subject due to intentional misinformation around 2010 by oil lobby and associates (ADAC first and foremost).

Here's what I learned about E10:

It's likely about as energetic as regular fuel (the chemical energy reasoning falls short due to side effects).

Its Octane Number is higher than regular fuel due to ethanol's Octane Number.

It burns cleaner (less coking) and also has a cleaning effect - again due to the higher ethanol content.

It's hydrophile qualities are actually an advantage as that means it binds water which is entering the system.

Some gas stations sell regular as E10 (and then cheaper) because it isn't economic or possible for them to have yet another type of fuel in reserve.

The reason why oil industry hates E10 is because it is more expensive for them while by law (in EU) they are forced to sell it cheaper.

There's only one catch which I still didn't wrap my head around.

My Mazda brings 160k kms to the table and features a "maintenance free" in-tank fuel filter which is somewhat difficult to replace. Now I'm a bit worried that using E10 will release built up residue attached to the tank and clog the fuel filter. And I don't know how fast this would take place.

the enemy might even shoot mirrored rockets just to reflect the beam and scorch what's below ...

I don't get the concept of diet soda. If you consume something unhealthy - shouldn't it at least taste good? Or is it some sort of self-punishment?

to stop a bad guy with a gun it takes a good guy with a gun ... more guns - solved!

> I think this is an interesting perspective, it's very "American", it's like it has been accepted by these commenters that rampant thievery is a perfectly natural part of life and so, must be worked around rather than solved.

what do you mean? death penalty ... solved!

Full disclosure:

I intentionally keep the metal stripe unbent to create two air gaps to both sides of my nose for more comfortable breathing.

Cheers!

and your's is better, isn't it

have been thinking of taking up that hobby from time to time. somebody here with some insights into it? how would get started?

How do you make money with this as an author?

don't want to sound smug but I think this is very easy to understand with very basic knowledge about the immune system and some common sense.

interesting - is that a french press but with a smaller pored filter so you need more force and get more creamy consistency?

having said that the design is remarkably ugly. almost like some medical device - or maybe even like a bathmate? :D

that's an interesting design. never seen that anywhere. do they hold the patent but fail to scale beyond italy? I find usual espresso machines to be too complicated and technical - also too expensive.

Well, I'm sure you can also contribute to "real communication" by now.
