International / Superconductivity and Design
« Last post by Frederic Bouquet on Mon 2011-10-03 23:12 »
So far, superconductivity was mainly the domain of researchers in quantum physics and engineers. Good people to be sure (some of my best friends belong to these groups), but sometimes somewhat dull in their approach of things.

To change this, students from the French Design School ENSCI-les Ateliers have spent four months working on the idea of superconductivity. Their talent and imagination led to several projects that are very interesting and creative. You can find their works in the following website (in French and English):

www.supradesign.fr

Full of videos, pictures, making of, and drawing stage of the projects. Don't miss the superconducting jewelry, the amazing machine, the "no contact" shoes and more!

Enjoy,

Fred

International / New mosem.eu website
« Last post by Vegard Stornes Farstad on Thu 2011-09-15 11:50 »
We are happy to announce that the new mosem.eu (or mosem.no) website is on the air!

Dedicated to the project outcomes, you will find an overview of our web resources, physical products and a little about the projects themselves. We look forward to have you as a visitor.

Please use this thread to discuss the new website, or submit feedback using the comment form on the site.

See you on mosem.eu!

Now you can also find us on LinkedIn :-)

We have set up the following URL shortcuts to make it easier to locate us:

twitter.mosem.no or twitter.mosem.eu
linkedin.mosem.no or linkedin.mosem.eu
facebook.mosem.no or facebook.mosem.eu

See you there!

We have now set up a Facebook page for the MOSEM² project:
https://www.facebook.com/pages/MOSEM%C2%B2-Project/195032667228703
Please visit! As soon as we have 25 likes, we can get a username and a shorter/nicer URL.

We also have a MOSEM² Twitter profile:
https://twitter.com/MOSEM2_Project

You are welcome to follow us both on Facebook and Twitter for updates about the project's results and impact. We conclude the official project period in one month, but the legacy will live on!

I have now pointed superconductivity.no and www.superconductivity.no to www.superconductivity.eu/en

The autodetect didn't work for me, so I got it in French. And I think most Norwegians prefer English (even after Stamford Bridge  :P).

Furthermore I discovered that superconductivity.eu doesn't work, only www.superconductivity.eu. I would recommend that you fix this, since most sites don't use "www." anymore, those are 4 unnecessary characters. By comparison, supraconductivite.fr works fine.


- there are two addresses so far, that point toward the same site :
www.supraconductivite.fr
www.superconductivity.eu

The language used in the first place is autodetect from the settings of your browser. It should be english for you, but of course French for me. There is a possibility to switch languages at the top left of the screen.

International / Re: Maglev train, anyone?
« Last post by Vegard Stornes Farstad on Mon 2011-06-27 22:02 »

Well, Maglev means magnetic levitating (train) ; there is no use of magnetic levitation if you use the ground effect principle I guess. Now you could use propellers as a way to provide thrust to a maglev, that is a question of engineering the optimal solution.


I meant that a maglev train which also was designed to use the ground effect would use less power for the maglev part to stay afloat, it would simply be a more efficient maglev. And yes, maglev and "magprop" (magnetic propulsion) are separate systems as far as I have understood, but I also believe that you can find some designs that combine the repulsion upwards with repulsion/attraction forwards (using AC). I am even more out of my depth here, but in any case I think it would make sense to use aerodynamics optimally for a maglev as for any other train. And in the case of a floating train (maglev), the ground effect would be useful - unlike for regular trains and F1 cars, where they have to be careful NOT to lift off...

What I don't understand is why maglevs cannot be designed to take advantage of the same effect. No reason why propellers must be used in combination with the ground-effect principle, is there?

This "train" was in direct competition with the French TGV (rapid train on rails); the latter won, the former disappeared...


The Japanese have their own version that they claim have advantages over maglev trains:

Not exactly a maglev (no magnetic field), but levitating nonetheless :
