ok so this is a bit random and nothing really to do with free energy, but i just had a thought...
force fields, sheild blah blah are in most sci-fi movies and tv shows in one form or another. I read last week that one had been made that created an invisible wall in some factory purely by accident and seems they cant replicate it on demand.
However, technically our blood has iron in it which is a ferrous metal, no matter how minute this would technically be affected by strong forces of magnetism, as seen in xmen for example. yes i know this is starting to sound ridiculous...bear with me.
Technically could you not use....somehow...magnetic fields to create a force field that would effectively stop a person dead in their tracks?!? i had actually thought of a theory when i started writing this post and now it's totally dissapeared from my mind so this post isn't as descriptive as it was originally going to be. if it comes back to me i'll post more.
The iron in blood isn't a magnetic form. Good thing too, or MRI and CAT scan machines would probably kill you.
So I think magnetic force fields of the kind you describe, acting on blood, probably won't work.
Electrostatic force fields, now, are a different story. I think the "wall" you describe, if it's the same one I heard about, was electrostatic.
I think it should be possible to use electrostatic fields, produced by very high voltages and field-shaping electrodes, to do all those "science-fictiony" things, like personal armor, tractor beams, walls of force, "bubbles", and so forth. Charge can be transferred in vacuum by plasmas, and wherever there is stuff around, like spacecraft or spacesuits, the local vacuum isn't going to be very good anyway.
well if u use a strong enough pulse of EM waves i believe u can erase brain activities by introducing a one-big-all-cooking-spark ;) is it what u r looking for :) ?
when someone will come up with antigravity a shield would be an antigravity field :)
Sorry but the best force field I have ever come against is a welder who hasn't taken a bath for a week. I am talking about 4 ft repulsion. PU! ::)
hahaha. great. Yeah i realised the iron in your blood isn't a friggin magnet after i posted but then went to do something else lol. yeah it was electrostatic the one i read about. in a sheet plastic processing facility if i reember correctly where the plastic wrap was travelling at like 1000 meters per second across a conveyor belt.
an anti gravity field is a decent proposal however i think this would have to be like -200Gs+ to instantly stop something like a bullet for example. But yeah theoretically that would do it. nice :)
Recently released game Red Alert 3 has a device called nanoswarm which creates a protective bubble around tanks etc. Supposedly it's microscopicly thin layer of matter hardened in air somehow. No idea how much merit that has in reality, but I just thought it was fairly creative idea for a shield.
Technically magnetic fields affect everything, just very little. Nasa has a lab with a magnet so powerful that it can attract even organic objects. There's a funky video on youtube where they suspend a frog in air with it.
so then technically my original thoughts could be theortically possibly, maybe just not in the initial way i thought. It would need to somehow magnetise the object coming toward the sheild to the same polarity of the sheild in order for it to repel it.
