Walk and Generate....Walk and Generate

The trouble with all these electricity-from-movement surfaces is that they make the movement harder because you're moving across a squishy surface.  They keep being proposed for roads or paths in one form or other.

The energy is not free of course, you now have to do more work. Most useful on things where the movement is something you'd like to damp anyway. Its also not really lighting that lamp to any useful extend in the video, from quite a hard stamp we get a brief pulse of the filament LEDs that should be painful to look at with even a few watts, so probably less than a watt at peak.

How much additional energy is use to make the extra materials needed? The energy produced by a floor will vary by orders of magnitude depending on where it is installed, but I suspect there will typically be a net loss in energy over the lifetime of the floor if this is factored in. It may also make recycling of the timber more difficult if not impossible in practice, so the environmental impact is probably a negative one overall.
