I'm an Apple hater. I hate its business practice, greed that's way above and beyond the norm, hubris, closed eco-system, terrible OS, dumb/outdated design (but marketed to shit as "intuitive/elegant") on and on I can go, but one thing I can't fairly hate is its hardware build and material.

I don't see much wrong (other than "not optimal") with the heat sink/fan distance here. The way the fins are aligned do allow air flow to direct to the fan. Takes a fraction of a second to generate the wind tunnel effect, and all the components between the fan & heatsink just need to be able to withstand the heat, and they surely do.

It's easy to see why they do it. That's "height". Apple want to make the Air as thin as possible, they can't do that by stacking 4 components together.

The fact that the current state of the technology is not public knowledge, and the fact that it's development is a secret military program, likely without a publicly available budget in all 3 countries, makes me think it's secret. Just tests on models require a supersonic or hypersonic wind tunnel....you don't pick those up at home depot.
Nobody has seen one fly, so if it was even in the early testing phase, no one noticed. Since we're watching, I'm dubious it's past models and simulations anywhere.
I don't doubt they, like us, are working on it. I have doubts any nation has made exponentially more progress than we have, and I wouldn't trust China or Russia if they claimed to have them without seeing them demonstrated successfully, just as they shouldn't trust us if we make more unsubstantiated claims, we're proven liars.

@vil
here is the thing though,and it is something that i find very disappointing.

when maddow came over from air america radio,who worked with such hosts as thom hartman,sam seder,lawrence odonnell,al franken,laura flanders.she was fantastic.

yes,she was a tad biased and the political points she chose to cover tended to lean liberal democrat,BUT her analysis and her ability to break down complicated and complex political issues into easily digested and understood nuggets,was a talent i truly admired in her.

in my opinion,she was the best host MSNBC had on their channel,and proved time and time again just how political saavy she was,and her ability to expose political shenanigans was unmatched by any other host..again..my opinion..but then obama won his second term,and i noticed a shift in her show.

she slowly stopped being so voracious when it came to exposing the more...shall we say..venal and destructive policies obama was beginning to execute,and started making excuses for those activities.apologizing in essence.

ok..ok..she was becoming an apologist for the highest office in amercia.there..happy?

to say that watching this transition bummed me out is a understatement.for years i could always count on maddow to break down and disseminate political talking points,partisan wordplay and reveal the bullshit behind the polished turd.

then here comes the run up to the 2016 election,and i watched maddow,in real time,go from a part-time apologist for obama to a full time apologist for hillary clinton.

you can watch her actively cheerlead for clinton against sanders.even when the DNC was caught RED-HANDED fucking sanders over,maddow downplayed the entire mess,and focused on debbie wasserman shultz,while giving clinton a pass.as if debbie wasserman shultz was in no way connected to hillary..even when the evidence plainly proved that there WAS a connection.

so you are right @vil .
much of how maddow disseminates political situations is eerily similar to RT,when it comes to state sponsored cheerleading.

host:the problem we are being faced with is:apple or oranges.

viewer: but what about those bananas over there? and those cherries.

host:there are NO bananas or cherries!
there are ONLY apples and oranges!

viewer:but i am pretty sure i see bananas and cherries.

host:you are being a pinko commie,and why do hate america? are you a sympathetic terrorist? or just simply a racist?

viewer:sorry i asked.i don't want to be called an unpatriotic racist.

at least that is how i see it.
not saying my opinion amounts to anything more than screaming into a wind tunnel,but i used to really admire maddow.

I'm not sure why people seem to think this is an elementary problem. I seriously doubt that most people in this discussion studied anywhere near the math and physics required in the calculation in middle school, or even high school, or college for that matter. Having studied physics and math at all those levels, I know that wind turbines were NEVER part of the discussion. After looking up the relevant equations, I can see why -- they're certainly not trivial, and would probably required significant calculus to understand (derive). In university my physics courses were directed towards electricity, so I didn't get a chance to play with wind tunnels -- although I'd still love to!

Applying the oversimplified version of laws that you learned in early physics classes to reality can often leave you in stunned silence when reality seems to defy them. Things like the dimples on golf balls or sailing ships moving upwind are classic examples of things that you wouldn't expect to even be conceivable unless you saw it in action.

>> ^Barbar:

The point I was making was that if air passes through the turbine, (I am assuming) it leaves with a portion of the turbine's forward velocity imparted upon it. If this is the case, then doesn't it mean that the car's chassis, following directly behind the turbine will experience less drag, since the relative wind speed is lower?


You'd have to do extensive wind tunnel testing, but I suspect the turbulent air following the fan's passage would actually make the rest of the car drag more. Look at properly done wind tunnel testing, it's all about smooth flow, the most aerodynamic model is the one with the least eddies in the wind. In this model you propose there are tons of eddies and unpredictable wind currents before you even begin to introduce the body of the car.

If you could somehow design something that worked as you propose (which I doubt is possible, but it might be if you threw enough money at the problem), the infinitesimal gain would almost certainly be lost through the inefficiencies introduced by the necessary (for safety) fan shroud, and the generator itself.
