Every time a tap is turned on in a house, water flows at mains pressure. If a turbine were installed in the pipe that supplies a house, how much electrical energy could be harvested? The electric supply would be intermittant, but might be enough to power a smart water meter for example.

UK voltage was supposedly standardised with Europe at 230V in 1988. When I measure mine, it is always 244-247V.  I realise that this is within the 10% nominal tolerance, but why don't the electricity companies reduce it if they claim to want to reduce our power consumption, e.g. they give away free power monitors?

6.5% higher voltage means 13% higher power.  Obviously some appliances, such as kettles, won't be running for as long, but presumably TVs, computers etc. do use more power. How much more?

If I have a string of outdoor (parallel connected) lights and a high-speed camera, I believe that they would light up in sequence at about a nanosecond per foot, with some reflection effect from the open end of the string, ignoring any thermal lag in filaments. But do I measure distance from the switch, or the transformer up the street ?

How about an open loop of indoor (series connected) lights ? Do I have to wait for the energy wave to complete a circuit, or do the lamps come on in sequence both ways around the loop starting at the switch ?

(perhaps I should add, from the point of view of an observer equidistant from all the components)

But Let Me Tell You This You Called David Icke All The Above & Much More, & Yet He Is Right What He Has Said.

As For Me I Have Found A Lot That Has Been Going On Around The Globe Like America & Russia.  These Two Powerful Government Have Came With A Machine That Causes Tsunami's, Earthquakes, Hurricanes etc.

You Must Be THinking I Must Be Mad! However I Do Have Proof, Go & Copy This Link It Will Show You What A Machine Can Do When Mother Nature Is Controlled By Man

There Is 4 Parts To This Video However I Cannot Upload The Final Part As YouTube Is Playing up.  But When I Did Upload Part Three I heard The News There Was An Earthquake In Spain, No Coincidences There.

Keep In Mind, Why Would Anyone Keep This TopSecret & Classified? My Question Is This:

What Can We Really Believe & Trust When What We Don't Know What Is Happening Around The World? This Technology The Americans & Russians Are Using, We Need To Step In & Ask Questions.

I have recently watched my first horror movie, titled "The Mothman Prophecies". In it, a man loses his wife, and his telephone keeps making strange noises. He then discovers the two are connected. At one point there is a part where the mans' phone rings, and he unplugs the cable. The phone starts ringing. Is it actually possible for electric signals to transfer across phone cables without wires?

I am aware that this appears to be instances of the paranormal, the scenes and characters are exaggerated, and that electricity can "jump" at high voltage.

Whilst walking in the snow i noticed that around electricy pylons the snow had formed a spiky texture similar to that of some cystal structures, all pointing in the direction of the pylons. Is this to do with magnetic attraction of the polar water molecules or something more comlex than my simple chemsitry can explain?

Thanks
