14. Febbraio 2012, 22:24:41 Argomento: Re: Free energy (V): Thank you for the link. Had a skim read, but will look at more carefully later, with an open mind :) I did pick up two statements in the article "...you can’t get more energy out of a system than you put into it," and "more energy can’t be taken out of a system than is put into it or is already in it.” The former statement is of course wrong as the author argues. Whether it be solar, wind, geothermal, hydrocarbon etc. these are all forms of potential energy, which we then convert (mostly) into kinetic energy to generate power. The latter statement is true, imho, and refers to perpetual energy / motion machines which are not possible. I believe this is what you referred to as 'free' energy. But I'll read the article carefully first! 14.

They still have to fly. 15. Febbraio 2012, 17:39:55 Argomento: Re: Free energy  (V): "They still have to fly." thats only because gravity is free also!  15. Febbraio 2012, 18:53:34 Argomento: Re: Free energy  Bwild: Oil is free as is gas and coal. Oh wait, there's a cost to harvest it. But there's a cost associated with all energy sources. NO energy source is free. There's always a cost involved. Even once the source is tapped, there's a cost to maintain the equipment that captures the energy. Unfortunately, we are years away from using renewable energy sources effectively and efficiently. In the meantime, I say drill and tap ALL sources of energy.  15.

Artful Dodger: I can we gather all the PR folk from the Republican 'candidate' race, and place them in a big biomass plant?  15. Febbraio 2012, 20:08:09 Argomento: Re: gravity is free also! Bwild: Yep... especially at terminal velocity!! 16. Febbraio 2012, 01:16:59 Argomento: Re: gravity is free also! (V): what does terminal velocity have to do with the fact that if birds dont flap..their gunna fall..no matter what their terminal velocity is. gravity WILL win by confrontation with the earth! lol 16. Febbraio 2012, 11:02:21 Argomento: Re: gravity is free also! Bwild: It was a joke!! Birds though through soaring or ground effect (skimming) can delay greatly the energy they need to use. |
