And this is a bigger one !

Hi Nelson. Yes, 10,000uF @ 450V can store a little over 1000 Joules!
That won't just kill you, it can probably evaporate you. ;)

   But, is it OU???   Just kidding...   We need some laughs, once in a while. Right?
   BTW: I really like your self running set up, Nelson. Wish that I had one, as well. Maybe someday.   Watch out you don't evaporate. We'd miss up. Glad that you are posting here again. Maybe people will be friendlier, in the future.

  I can imagine what those caps would cost. Pretty nice gear that you have now. Nice going.
  So, it looks like you are able to separate the input drawn, from the output drawn. Correct?

Hi Nick , that system already gave me more problems, than profit  Nick you don't imagine ..... let change the subject ..
About people become more friendly , is it's debatable that happens because since i know this forum , some hostile opinions come up all time ,  by some elements with a bit more hard approach .


Nick All the best

Nick at moment i only have one . That conf in the video with 8 caps stay retained in Germany like other stuff .
But that stay in my home but yes they are very expensive .

Nick, i know my videos suck , because i don't talk and have bad video , but what is your perception of what is happen  ?

Hi Nelson, I don't have time to watch the video now, but I will try to watch
it this evening and then give you some feedback. :)

Sr LancaIV ,
não conheço esse video mas após ver o mesmo não tem a ver tecnicamente com aquilo que mostro no meu video mas obg .
Feliz por saber que mais vozes  Lusas andam por aqui  :)

Cumprimentos :

Eu percebo a sua demonstra, um pouco tambem" electric wifi radiant distribution".Mas o produto seria o igual : ter ao fim um sistema autonomo

Ate breve

I think i have 3 x 50,000uf at 450v i recovered from a 3 phase drive in my shack junk box.
Imagin dumping that fully charged into a 6 turn Tesla coil using a solid state spark gap  :o 8)

That's a lot of energy all right! I wonder what would happen if you overvolted that thing and it exploded, like the one that almost killed me. That cap probably was holding about that same 1 kJ energy when it went, but at a much higher voltage.
450 volts won't jump much of an air gap. 60 kV on the other hand....

Hi Nelson, regarding your video:
Unfortunately I know very little about motors, but I think that motor's power
consumption is rated around 400 Watts under load? Is that right? 
If that is correct, and since the motor is running with no load, then if we take the
motor's power consumption with no load (power consumption due to losses in the motor only) as say
15% of 400Watts = 0.15 x 400W = 60 Watts
If the input power to your radiant charger device is around 70 Watts, then the setup seems to be performing within
what would be normally expected, but I know little about motors, so I could be wrong with my rough estimation. :)

P.S. That was a very nice bench power supply you were using! :)

 Hi TK ,
By accident the pack of 8 in parallel was shorted in the output. I have tinnitus caused by the explosion of that short circuit, is indescribable what happen. the light of explosion  blind the 3 persons in the room under 5 minutes. i could die . Yes very danger when we are talk of capacitors .
I have loan to a friend a 30kv 3uf is the bigger hv cap i have  very danger to better be immersed in oil at that levels .


cheers
