"“When you consider all of the man-made radiative forcing and all the changes we’re making that can affect climate, contrails are one of the smaller effects, compared to carbon dioxide and other emissions,” Spangenberg said. “Globally, you would have to increase the contrail effect by roughly 100 times to get the same effect as all of the anthropogenic carbon dioxide in the atmosphere.”"

If you can flight forever, who cares ? You only need to takeoff once.

The energy consumption of a takeoff depend on the mass of the plane at that time (I think), so for a given plane with a given number of passenger, it's not exactly independent of the distance. (more fuel needed for longer distance, bigger take off mass)

You speak about aerospace where you should probably speak about aeronautics. In the aerospace sector, people rely a lot on non carbon energy, except for the launch part. Of course a launch is a big energy consumption in a short period of time, but on the other hand the S/C will usually be used for 10+ years, running on solar energy. And more and more S/C use "electric" propulsion, where you have still a "fuel" of course, but most of the delta-V comes from electricity.

There are some people who want to use renewable also for launches. Or at least it's a side effect of trying to simplify/reduce the launch cost. For example zero2infinity is planning to use balloon for launching rocket from high altitude, avoiding the dense atmosphere (even better, they use it) and the drag, and also starting from higher slightly reduce the delta-V.

There is no good reason to pay a good negotiator more than a bad, except if you want to hire someone for a position where you need negotiation skills.

Andorra and Vatican are not fully part of European Union.

It's a group of national government which have decided to overrule the EP. Which ones ? I don't know. But just a possibility. If roaming becomes free, some operators will lose money. And some European operators are partially owned by countries: Orange (France), Deutsche Telekom (Germany), Belgacom/Proximus (Belgium), ... So they may have a reason.

Helsinki has less than 6 hours of daylight in the winter with a maximum elevation of 6 degrees (on worst day), so it's not easy for solar arrays. And it's in the southern part of Finland so it's worse for the rest of the country. (to be honest the southern part of Finland is also where the vast majority of Finns are living) Nordic countries are not the best place for solar power. But other (renewable or not) sources can be considered, of course.

Who's paying the air I breathe? Who's paying for the rain water that I collect?

That's the goal of the call for proposal. Something like "Dear scientist, we have a budget of 300kg and 50 millions euros (out of which x% must be kept for the platform). What do you want to do?"

Nor did Hollande, Sarkozy, Chirac or any french President (or prime minister). There is no such camps.

It's difficult to get rid of something which don't exist. But be reassured, the number of remaining "no-go" zone is now zero. Vous pouvez éteindre Fox News et reprendre une activité normale.

If you have any useful information to identify the people flying the drones over the reactors, I think some people may be interested.

If you put it in the center of the country, people can also come without presenting any papers from all directions.

Can you give us two of such enclaves (two is the minimum, as you use plural). They must respect the conditions that you gives:

• 1) be/becoming a Sharia-run enclave
• 2) Absolutely no moderate* muslim said anything or did anything about it

* From what I understand when you use "moderate" in front of muslim, I would probably call them just "muslim" or "normal muslim", but I have kept your word.
