You keep saying that, but it seems that you're only able to make sense of the article because you have some prior knowledge. I was hoping you would share that knowledge, but it seems you have no interest in doing so. What was the point of sharing the article then?

Since you seem to want to be reductive, it appears that this detonation engine is nothing more than a regular combustion engine with a fuel mix that is more reactive. That's great and cool, but it still isn't clear why this is any significant innovation.

I could be very pedantic here, but I'm actually trying to understand how this is different from a traditional engine.

In that sentence, what does the "required pressure" refer to? Presumably an elevated pressure is required, instead of a negative pressure? For what purpose? How is that pressure achieved? Is the pressure changed by a change in volume? Temp? Once the pressure has changed, does the gas do work on something?

The KIT system creates the required pressure inside the combustion chamber instead.

I'm specifically referring to that line.

Thank you, but that explanation is causing more confusion because it is at odds with the article. The article states that compression is required before ignition. Is that true?

If not, then in the detonation engine, is the fuel mixture already at explosive concentrations upon mixing?

The article isn't very clear about how compression in this engine is achieved, but it's clear that compression is still required.

How is this different?

There probably is some novel idea here, but the headline and description could also apply to regular gas engines...

Would it be ethical to knowing give someone a 99% chance of a severe illness within a few months?

I'm sure Iran knows to "never interrupt your enemy when they are making a mistake".

You can Google those ingredients, they have specific names which makes them sound scary, but they are all pretty common in normal fruits and vegetables. There's no need to fearmonger.

Sorry that you had GI issues.

BTW, cellulose is just fiber, it is the cell walls of plants.

Also, look up the ingredients of a banana. It has several E numbers.

That article indicates that phytosterols may have a range of benefits. What exactly is your concern?

Not quite, a few quick notes:

  • white bread is fine, it is no better or worse than other sources of carbs. Whole grain bread is preferred because of the additional fiber and other nutrients, but so long as those are obtained by other parts of the diet it's not a problem.

  • margerine used to have lots of trans-fats, but thanks to improved regulations it may actually be better than butter for some health conditions. Most margerine is oil and water. It is still fat so should be consumed in moderation. Flavor wise, butter tastes better to most people.

  • frozen food quality depends on the ingredients, not the freezing or place where it was made. Frozen fruits and vegetables are great. Frozen chicken has lots of protein, just like chicken.

  • emulsifiers may be good or bad. Eggs and mustard are both emulsifiers. Those may or may not belong in an individuals diets. Emulsifiers by themselves are not universally bad for people.

  • seed oils are typically lower in saturated fats, cholesterol, and are generally recommended as healthier options compared to saturated or animal derived fats. Seed oils are good.

  • many common commercial preservatives are salt, acid, and sugar. The amount in the fodds and the amount consumed are the what needs to be considered.

So then say that those ingredients are your concerns.

It would also be reasonable to acknowledge that salt and sugar are excellent preservatives often found in freshly homemade items. As is the case with all these ingredients, the amount makes that difference between a healthy or unhealthy diet.
