It does, and saltwater isn't conductive enough. The effect degrades the lower the electrical conductivity of the medium in which eddy currents are formed. Pretty much requires something like copper or silver (or gold!) for high enough conductivity to make it work. A superconducting surface works great for this.
- mrfusion 12y agoHow about aluminum?
- FiatLuxDave 12y agoIt should work, but less well. The conductivity of aluminum is more than half that of copper, so I would expect their 100 lb board which can hold a 190 lb person to be able to hold at least a 100 lb person. The thickness of the metal plate also has some effect, but it is limited, and I would expect that their plate is already thick enough for additional thickness to not matter. I don't think that you can compensate enough for material conductivity with thickness, but I don't have time to research that at the moment.
