Maybe a series of magnet pairs, spaced at different heights, could approximate the spring effect. Each pair would be bound together (e.g. with strapping) with the negative charge being on the outside, since Earth has a negative charge. The bottom of the stick would have the strongest magnet, negative charge facing up. - + + - The pairs could then repulse each other at a closer distance, approximating the spring function. I accept royalty donations :-)...but it's probably patented by now.
