Reply #4: Isn't There Some Sort Of "Pressure Generator" That Fits Inside... [View All]

[arwalden]

... the heel of one's shoe? At least a concept of something like this exists I believe.

By simply walking, one charges the batteries to their cell phone or pda, etc.

If I recall correctly, it's the pressure on a liquid that causes electrical energy to be released and stored. But I watch so much science-channel and TLC and DISCOVERY that I sometimes confuse them with the SCI-FI channel too.
