Hey, that is really cool! I subscribed to your channel, keep up the good work. Nice Wimshurst vids too.

You made me get my hands wet, though. But I'm glad I did.... a very cool demonstration that I had not thought of, and that will impress the heck out of some people I know... I hope. Thanks! And I am not kidding, I really mean it. Sometimes I just don't think creatively enough.

Nice! It would be interesting to see if the current draw/bulb brightness varies in tap water vs. LCW (Low conductivity water) vs. air. Using cold water would probably increase efficiency too.

Very interesting video...I have no idea how you did that.

I would guess there is a fairly high frequency transmitter inside the black case that the bowl of water sits on.  Power is low enough that the coil needs to be close to it to light up the bulb.  If he had no bowl of water but simply sat the coil on top of the case I suspect it would light up then also.  Because it was a high frequency source the water does not stop it from working.  Water is actually an insulator if it's fairly pure.   I think the reason he 'tosses' it into the water is because if it was slowly brought down to the water it might light up before touching the water so the effect of it lighting because of being in water would be lost.

Thanks....that makes a lot of sense.  I believe you are correct on this.  I did not pay attention to the case the first time I saw it.

Thanks,

Come on, it's all explained! I've got lots of videos showing the wireless power devices, explaining their performance, showing DC output, scope traces, etc. I don't want to hijack this thread, just look at my YT channel for "wireless power" and it's all explained in those vids!

I just never thought of trying it in water until I saw NTesla's neat experiment, using a bit of a different system, so I thought I'd see what happened. The black box just happened to be handy and have the horizontal antenna already in it.

Funny... that short video has gotten the most "thumbs down" per view than any other video I've posted !!

But I've just uploaded another video with everything in plain view, using a different transmitter, this one not boxed up.

I had posted my question after seeing your video and asking a question on youtube on how you did it....e2 answered me here before I read your answer and explanation on youtube.  I believe I was the first person to rate that video (thumbs up) and I have no idea why anyone would not do the same.  I have not been around here for a while and was not familiar with your power transmission vids.

I just thought it was fascinating and you answered my question with an explanation.  That was all.

PS I built a heron fountain today and it is also amazing to mess with.  My top bottle empties too fast (air leak)  so I need to tweak it a bit but, the water going higher than any other part of the unit amazes me totally.  It is really cool.
