Well,certainly it depends on the definition what alive means. Hawking is too optimistic regarding that definition and no biologist would agree with him that a computer virus is something alive,and many of them would even argue that biological ones are alive (they would tell you a viruses are...

A computer virus,eh?You are probably thinking of biological viruses flying all over around us ,not the computer ones. Yes,I consider such ones alive. Question for others :what about prions?I don't considered them alive.Just a dangerous substance.

Hmm,I doubt that.Now I'm thinking and I recon you can measure current , total charge transfer,or even to extrapolate the energy dissipated locally -in the place that particular lightning strikes. But total energy that lightning discharge release I think you cannot.

I pressume it can (to a certain and small extent),but without meaning of any facility of such kind for practical purposes in everyday life. This is explained by the other posters ^^). BTW,how is the total energy of a typical cloud-ground lightning estimated/calculated?Can it be somehow...

Answer This gallery has many photos confirming it does: http://www.genesisfineart.com.au/lightning_gallery_1/ocean_reef_4.html

TEV,capturing the energy from lightning doesn't appear complicated following your procedure.Can someone estimate costs for building the facility proposal?

Is it suggested that elementar photons travel and look like sine waves?

Thanks both of you for the enlightening, Tev:I appreciate your answer becouse we are going to learn AC circuit basics on class next week!I showed your post to the professor and he said:"That's right,I totally forgot about birds' capacity,and the current is offered virtually closed path to flow...

Thank You All for your replies, Njorl's explanation looks promising to me to describe the structure.The film isn't smooth but the window-pan is cowered by many of small water droplets of different sizes attached to the glass surface? If that is so ,what is the average size of such droplet...

I was told by my professor current can't flow into birds on power lines becouse of the same potential.Closed circuit path is needed for current to flow.

Hi, When I boil some water,and outside is cold,window-pans in my kitchen get steamy.Here comes my question.Shouldn't that thin film of water condensate be light transparent?I wonder why becouse it is nothing else but clear water. Does the film structure become corrugated somehow or other...
