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

Sr Lanca, viivemos muito perto . Eu moro na Maia e conheço muito muito bem Vila Chã quem sabe um dia ainda damos uma conversinha

Cumprimentos

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

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

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
