Joe1izzo, actually controlling the weather requires energy amounts that are at least on the same level as the natural ones we have to deal with. That's basic physics and I don't assume you will object. Now, what is the energy in a hurricane? This has actually been discussed...

The video in the opening post is also an excellent visualization of how aerodynamic contrails are forming in humid air.

We have been discussing a similar - non-military - engineering project earlier. A certain level of confidentiality is to be expected during development of new technology; it's just business practice. The original 'blow of the whistle'...

Movie version of wake vortices - SFX, but still a nice illustration (both from "Pushing Tin"):

If anybody living in Belgium reads this - it would be quite interesting and informative to have a time-lapse video from such a 'trail day'. Like this one from Amsterdam: BTW, this example shows how two or three plane routes (like the ones from the SkyVector charts) are enough to create a...

Planes from Frankfurt (FRA) and Munich going to East and Mid U.S. will usually fly over Belgium. Don't have the numbers ready yet, but that must amount to quite a lot. And that's just two airports.

Sounds like Dutch, that sentence being very close to German, translating to: "Yes, and this is really not normal". Can't understand the rest of it. Addendum: the style of the visible roofs matches that of Central Europe.

There is no point in speculating as long as there is no indication of significant levels of Barium in jet exhaust. So far, we have seen nothing but ground tests, mostly water mixed with dust. Plenty of likely barium sources on the ground.

If you make a claim, the burden of providing evidence is on you. You can start by pointing out specific factual errors - "disinformation" - on that site. If you can't find any, then your claim is baseless. If you do spot any errors, the site owner has pledged to correct them. Test him!

Well, then he has certainly explained to you how he determined the exact altitude of the planes/trails ?

Glycol is probably in every car radiator out there in the moderate and cold latitudes. It's not highly toxic (when ingested) - I remember it was used in a case of wine adulteration in Germany several years ago. No known health implications. Obviously, the size of the dose matters, as always.

Uhm, no. You seem to have found the evidence to the contrary already, so no more of that.

Addendum regarding air pollution: 25 March 2014 | Geneva - In new estimates released today, WHO reports that in 2012 around 7 million people died - one in eight of total global deaths – as a result of air pollution exposure. This finding more than doubles previous estimates and confirms that...

If you are implying that WeedWhacker is not an experienced commercial pilot as he states he is, then you are expected to provide evidence better than just "a laugh". Until then, he is what he says he is.

This is just semantics. It's not unusual to call the whole engine a turbine.

Where is the error? What should be corrected? Please be specific.

The downside must be that you need a bunch of additional systems to do the tasks previously shouldered by the consistent bleed air 'circulation'. It will be interesting to see how overall reliability is affected. The mass increase has probably been mitigated by significant reductions elsewhere.

In a nutshell: the cabin air is taken after initial compression but before combustion. The jet engine is used as a compressor, eliminating the need for an additional device. [Edit] Recommended read: http://en.wikipedia.org/wiki/Bleed_air

It may be of interest that there is a significant difference between the Ivanpah thermal facility that you refer to and conventional photo-voltaic facilities. The former operates with mirrors (designed for maximum reflection), the latter uses panels that directly convert light into electric...

I think the RVL news bit is a satisfying closer for this thread. Turns out the debunking "swarm" had it nailed down with almost 100% precision. As we assumed, the whole thing was not intended for a specific plane but designed to work on standard freighter configurations. The plane from the OP...
