NTT Energy-Generating Shoes Are Squishy

NTT is developing electricity-generating shoes that generate power from walking. These green shoes generate 1.2 watts of electricity - enough to power your tunes. I'm wondering if you generate more power when dancing, which would allow you to listen to your music at higher volume.

The characteristic I like best is that these shoes don't use those any of those fancy-pants technologies like Piezoelectric Zinc Oxide Nanowires or Biomechanical Energy Harvesters or Vibration Energy Scavengers. Nope, the NTT electricity-generating shoes use good old-fashioned water pushed through a turbine.

Each shoe has a small generator attached to the water-filled sole of the shoe; as the user walks along, each step causes water to gush past the small turbine, generating power.

Regular Technovelgy readers saw this one coming; I'm going with the cool Fremen stillsuit desert boots from Frank Herbert's 1965 novel Dune as a precursor for this idea:

Paul sat on the edge of his bed and began stripping off his desert boots. They smelled rancid from the lubricant which eased the action of the heel-powered pumps that drove his stillsuit.
