That’s like saying “other than a fast and efficient mode of transportation, of what practical use are automobiles?”

“sharpened on the edges for less air friction…”
I don’t want to put my hand near that! (Or any other part of my body!)

Nope, the blade is a solid aluminium flat bar, 5mm thick, 2m long and sharpened on the edges for less air friction… :)

Is it just me, or did that blade look like it was just a yardstick?

I’ve been thinking more about uses of LEDs.

Remote controls are another.
Opto-isolators, too.

And last, but most important:

Semiconductor lasers are a form of LED.

Think about it.

No, we use 2 DC Motors, ca. 12cm long, 5cm diameter, 200W peak. They go up to 80°C while running… We need to change that… :)

Did they consider using industrial grade single phase AC motor for their project ??

Looks like they had some trouble with the motor and its power supply…

There is definitely some room for improvements !! :-)

That is totally safe.

It`s not a lexan shield, it was wire mesh. It was operated in an closed area in order to prevent any dead people.. The Rotor stores about 800-900J…

The HV-Stuff in the lab has been re-arranged in order to create room for the party, during “normal” operation of the lab, the coils, generators and all the toys are a bit better placed… :)
The HV-Lab belongs to the swiss federal institute of technology (ETH) in Zurich, Switzerland and the party was organised by AMIV, the student association for mechanical and electrical engineering.

looks like you are reinventing the pulsed reactor core and neutron chopping.

Looks like they put lexan shields beside it at the installation. At the end of the video they have some rather huge tesla coils in proximity of each other. Is that safe to run, or would the TC’s interact dangerously with each other?
