It was interesting how a debate about something purely physical, the shape of an object, descended into a religious argument!
Everyone here has a bloody freezer, get off your arses, buy some distilled water and try it instead of debating it ffs!!
I just dont see how they can make it anywhere near 90% efficient! im suprised that they say it can be 45% efficient! How does it not waste electricity alllllllllllllllllllllllll the time its in use?
A coil which is fed with elctricity, from a wire, spews out an electromagnetic field,like this. . This field, if stable, exists quite comfortably (in this case filling a whole room), not interracting with anything, for as long as you feed the coil with electricity.
But if the magnetic field interacts with another metal coil u bring in to the room, this new coil will draw some of the energy from the field--- If u feed a coil with a magnetic field, it spews electricity back out, (a reverse of what happened to the fi
no one is saying, `omg there is definately life on this planet, we must invest the entire planets finances on going there.` It simply shows that earth is in no way unique. And therefore, probably, life is in no way unique either. Dont forget there have only been 200 planets discovered outside of our solar system, and ALREADY we have found one that bears a striking resemblance to earth, that might, MIGHT, be suitable for life. So, if there are 100BILLION stars in this galaxy alone, and hundreds of billions of galaxies, thats 10 with 100 zeros after it stars. if one in every BILLION stars had a planet orbiting, that would make 10 with 90 zeros after it planets. If we find one in every 1000 planets (rather than 1 in every 200, which we could feasibly say), that is earthlike, thats 2 with 88 zeros after it planets that could be earthlike. So its a big discovery even if this place isnt quite suitable for life as we know it.
