DIY ION Thruster Fan

ION engines are super cool.  They produce thrust with just electricity, no moving parts, no exhaust, no problems.  Well, one problem actually, the thrust produced is pretty minuscule for the input energy required.  The only place it works is in space, where there’s no friction to overcome and constant slow acceleration can eventually lead to very great speeds.

Well, Alex Reifsynder over at MAKE has put together a short series of steps to make your very own ion thruster, except you won’t be making any super cool vehicles, instead you will have a small, expensive to operate and dangerous fan.  Good luck, it’s pretty cool, haha, get it.
