Right guys, now we're rocking!!! Lots of members kicking in with opinions and facts. That's what a forum like these should be about!!
Great job! Keep it coming!

Love to hear more opinions and facts on this as it is key to the discussion we are having. Mind you, I don't believe the air is denser as the compression ratio tends to be lower.
Still, begs the question, does denser air allow for better, more efficient combustion?? Any takers?

There is nothing wrong with relying on the web for information, but it is really down to how you validate whether its relevant and true, ie what are your criteria to conclude it's true?
To be honest, I don't have a very scientific method. I look at the text, the source, I look at how it;s written, whether I feel it is generic information or backed up by imperial or scientific facts. Then I decide whether I believe it or not. Not very scientific I grant you that. But on topics I consider myself knowledgable, I am very critical, and on this particular topic there is an awfull lot of nonsense out there. True, in the eye of the beholder. But that is where a forum likes this comes into its own. Here we have real individuals that can make a point, drill down into facts or the lack there off.
As stated before I'm an old git, so I don't necessarily get the WWW, still struggling with Facebook for that matter. I am of the opinion though that the Internet offers a wealth of information, but that the more classic way of gathering knowledge, ie studying, books, classes, research, discussions is more meaningfull than googling for a particular topics/answer. The reason is very simple. It takes me a few minutes to type this whole reply. But to write a book to teach for an hour a college take far more time in preparation. And is likely to be much more thorough. The real problem with the net is that everybody can pose as a specialist and quite a few do, but building real knowledge, experience and competence takes much more than surfing the web. I know I'm old git, but I do believe very strongly in classical education, where you discuss and probe real experts to broaden your own horizon.
I have been called many names, quite a few of them not very flattering. But nobody that knows me would call me an academic. Still, I have come to appreciate the very essence of a more academic approach to anything in life. And it's really at the level of a toddler. When somebody explains or argues a point and you can still ask: Why? You know you haven't really understood the topic at hand at all. That doesn't mean you need to be an expert on every topic, but be asking "why" you'd be surprised how many so called experts shut up. Again, opinion, I think they just haven't got a clue and at best googled around the WWW a bit. No harm in that, but it doesn't bring any real value. Insight, the attitude to dig in and to want to understand a topic at hand is what I find is relevant. Again, just an old git's opinion. My kids think I'm going mental. I don't think they know how to read a book, but they are way ahead of me on their smart phones though!
I'm very lucky as tomorrow I'm leaving for a course at the Sante Fe Institue, NM, USA to do just that.
http://www.santafe.edu. Spending a whole week with top experts in different fields, disciplines and expertise discussing, probing their minds and learning about how to deal with complexity and innovation. So I might drop out of this discussion for the next week or so.

With BMW recommending people to drive their cars for at least 20 KM per week to maintain the life of the battery, I have reasons to believe that electric turbos will strain the system. |
Was new to me as well, at least for automative applications. It will put additional strain on the dynamo/battery as it is an additional load. Its the engine, (indicated horse power as I stated before) that will make need to make up for it. So you loose a bit of power to the wheels, because you need to drive an electric motor to drive the turbo. Very similar to a supercharged engine where the same is applicable for driving the supercharger. The difference with the electric driven turbo is that you can hook it up to the ECU and control it very efficiently. I suppose you could hook up a supercharger to an electric motor too?

Not to worry I too go through these episodes more often than not; but thankfully not when I am treating patients. |
Oh man, this is getting embarrassing!! Put it down to me being an old git, who can't remember his thermodynamic lesson anymore!!
Please be careful with those patients!
