660 Volt Beaded Curtain provides easy access for all
(when it's in the off position)
You can allow the wind to blow through it and come and
go as you please, parting its beaded strands easily with a
flick of the wrist, but once switched on, it becomes a
deadly barrier to man and beast alike.
A
deadly hum is emitted along with the occasional spark
of electricity. Its range of graphically dire warning signs
depicting the foolhardy being fried into burnt toast serve
to deter all those who otherwise risk passing through the
deadly hanging strands when the current is on.

Extra credit for making the header panel look like a Portuguese man o'
war. |

Crank it up to 2000 volts, and you could do fractal wood
burning on the floor. |

Clever. For added effect you could have Jacob's
ladders going up and down. You'd have to have it
wired differently than the standard Jacob's ladder
but
it could be done. |

Well sure it's pretty and all... but is it current? |
|
| |
? Why does the line spacing look so different on an
iPhone or iPad to that of its appearance on a
laptop? If I try to correct it on iPhone, it makes it
even worse. |

I don't really get it. I used to regularly take 110 volt current tiling kitchen back-splashes. I even took 220 volt one time backing into dryer wires, hanging out of a wall without marettes so I assumed they weren't live, while spreading linoleum glue holding a metal spreader to the wet glue. |
|
| |
I had to fling myself bodily into the glue puddle to disconnect and if the homeowner had been present when I did so I might be in prison to this day I was just that angry. |
|
| |
...but I didn't die from these things. Can so little current really kill people?
Fascinating. I thought it was only Amperage which killed and that humans can take thousands of volts without harm. |
|
| |
...not sure where I got that concept from. |
|
| |
I routinely wire stuff around here without shutting off the breakers. True story. When I built a 1500 ft addition on our last home I traded tile work for electrical rough-in. My buddy showed me how to hook up the first three way switch and said he'd show back up after I installed the 'everything' and flip the switch back on.
I told him to leave it live so that I already knew they worked before I had to call him and did all of it live. |
|
| |
I got shocked a couple of times but in my experience... 110 volt is the equivalent of a morning coffee without the bowel movement. |
|
| |
Honestly... I don't get it. 110 volts is just a wake up call. |
|
| |
Swear on me mum. I've taken 110 volts so many times I lost count years ago. |
|
| |
I swear it on my eye sight.
I don't much like the idea, but I can show you if that's what it takes. |
|
| |
Where did you get 660 volts from? |
|
| |
I didn't find any stats on electrocutions from 110 or 220V.
I think those are actually fairly rare, but it can happen,
and there are other potential injuries and damage that
make it worthwhile to turn off the breaker first. According
to Wikipedia, 2700V is "often" fatal (which I would interpret
as still less than 50%) and 11,000 is "usually" fatal.
Apparently there has been one documented case of
someone being electrocuted with 42V, though that is
generally considered safe. |
|
| |
So [2 fries] I'd say your experience is normal in this regard.
I've been bitten by 110 a couple times, and I agree it's not
that bad, but I still turn the power off when fixing outlets.
I suspect most injuries when shocked by 110 or 220 are
cause not by the electricity, but by some other means when
a person jerks away without thinking (or get's ahold of the
guy who left the breaker on :) |
|
| |
I have had a few 240 volt 13 amp shocks and can
verify they are to be avoided. 110 volts is for
powering toy train sets. |
|

What happens when the wind blows strong enough
to short the curtains to the wall? |
|
| |
It occurred to me that since I mentioned it here, people might
investigate, so I really ought to point out that fractal wood
burning is quite dangerous and you probably shouldn't try it -
even if you think you know
what you're doing. |
|
| |
// What happens when the wind blows strong enough to short the curtains

|
| |
Be kinda cool to have every other curtain streamer at ground potential, so
that when the wind does blow it makes pretty little sparks. It would need
some sort of electronical doodad in the circuit to keep the power live even
in the occurrence of a few sparks. |
|
| |
//short the curtains to the wall?// Insulated walls.
Heavy beads will also ensure there is minimal wind
movement. The wind will simply pass through, but
it's inadvisable to follow when curtains are "on". |
|
| |
Under a very specific set of circumstances, even 9V can kill. [link] |
|
| |
[whatrock] the live streamers could be connected with a series resistor to limit the current, although that would also be less of a deterrent. A set of experiments could be devised to select the resistor value... |
|

It's all VERY dependent on the conditions. As is WHY the electricity is lethal. The most direct and simplest way to die from electrical shocks is to get a few mA of 50-60Hz across the heart. 50-60Hz is an unfortunate choice of frequency for mains electricity because that's something of a sweet spot for stopping the heart, it's slow enough that the heart electrical system can interact with it, but way to fast for the muscle to keep up. |
|
| |
How you get those mA across the heart is important, you'll see electricians probing panels with one hand lookin lazy with their other hand in (usually the back) their pocket. This is because if they touch something live, the electricity has a route in through the hand. It needs a route out to flow, if they were holding a rail/the metal enclosure with their other hand, they're in trouble at relatively low and frequently encountered voltages. Dry skin helps, gloves help etc. |
|
| |
Now if they were standing in salty water, then the electricity can go in through the hand and out through the legs, but mostly it isn't going through the heart and the mechanism isn't so specific, instead you're cooked by large currents. |
