Thanks to G. Charles (aka Padawan on forums) we have just made a video of some "basic" measurements under a very high voltage 400kV Edf line. Voltage, intensity and partial ionization measurement of fluorescent neon tubes.
Here is the result in video, lasting more than 8 minutes!
Other popular science videos are in preparation, particularly on MHD, plasmas and microwaves!
If you have any ideas for experimentation, please let us know on the forums. Econologie.com is there for this too!
