Guest pilsner_67 Posted April 29, 2005 Share Posted April 29, 2005 hello everyone, sorry if the answer to my question is easy to find if i just look but the further down the screen i go the "stupider" ( not even a word) i feel. but here goes.... does anyone know of any gas or gases that have a reaction of expanding when introduced to a low (?) level of electrical current. gasoline has a high reaction to a very intense ( sparkplug firing) and is subsequently burnt up. i'm thinking about a gas that would expand but not burn or explode . but rapidly expand. and upon removal of the electrical charge ( or current) would cease to expand and revert completely or mostly back to its original state. if anyone knows anything like this i would appreciate some info as i am doing some research. thanks pil Link to comment Share on other sites More sharing options...
losfomot Posted April 29, 2005 Share Posted April 29, 2005 I don't know a lot about gases, but it sounds like you could run a motor with this gas and never have to refuel it.... sounds too good to be true, so probably not. Link to comment Share on other sites More sharing options...
swansont Posted April 29, 2005 Share Posted April 29, 2005 I don't think you could do this with a gas. You need long-range order and lots of interactions, which basically means you need a solid in a lattice. Piezoelectric devices expand when you apply a voltage (or generate a voltage under pressure/compression). Solids can have different behavioral characteristics along different axes, but the randomness of a gas probably precludes this effect. The only possibility I can think of would be if you could polarized your sample and maintain that. Then there's a slight possiblity that there could be expansion along one axis due to an electric or magnetic field. But I've only heard of this type of thing happening in solids - not liquids or gases. Link to comment Share on other sites More sharing options...
