Will this work do you think ??

They are £34 at ebid .

huh!


are you awake? did something infest your head, or, PC ... them links ain't got nuffin to do with saving anything.

Methinks you've been pranked

Somebody thinks your name is Mr William Anchor

Sorry guys . New link posted . They have some neat gadgets on the site but theyt are all a wee bit expensive . Like the Intelli plug ones though .

They are actually selling that unit I've done a google for the name and loads of places stock them!

I'd love to open one up and see what's inside Fluff and an LED?

And where is the bit that should tell you that it "conforms to" such-and-such an electrical safety standard - the kite-mark thingy? Just a thought

"I'd love to open one up and see what's inside Fluff and an LED?"

Probably a whole lot more - My best bet is it's a Power Factor Corrector.

[TECH] When you draw power from the grid, via a socket, you demand voltage and current. If the voltage and current are being drawn together, at the same time that is, then everything is in harmony and you are using the power the most efficiently. However inductive loads (such as motors) will draw the current after they have drawn the current (the current will lag the voltage.) This results in current turning up before it's needed (along with the voltage) so some gets wasted. A Power Factor Corrector tries to make the current & voltage draw happen as close to the same point in time as it can - usually by using a stinking great capacitor.[/TECH]

So if you ever pick one up it should be quite heavy, if not like Ian says it may be a con.

I like Electronics

I reckon that things right up there alongside tartan paint

But I could be wrong.....

I'm just trying to figure how a huge capacitor (1 farad?) could 'harmonise current and voltage'. All a capacitor does is store a charge, semi-smooth AC and block DC.

(Generally speaking, I won't go into more specialised applications like de-coupling and stuff)

And electrolytic capacitors don't weigh much. But paper ones do, as once commonly used in strobe lights.

Still, I ain't no scientist......

Flops: Apparently (I'm first year, we only learnt this last term) the capacitor stores the charge when it arrives 'too early' and then releases it when the appliance tries to draw it, at the later stage. Makes sense, I suppose. I assume I will be given a better explanation in later years...

That be true, but I can't see any device synchronising that accurately to result in a saving of money.

With a capacitor, if you imagine the incoming mains AC as a running tap filling a bucket (the capacitor) and the bucket has a hole in the bottom, that hole will let out a constant steady stream.

How's that for a scientific explanation?

So they may work or they may work or they may not then .
