<DIV><FONT size=2>The whoopie cushion idea brings up thoughts of places where
energy is just dissipated by creating noise or heat: Sitting down in a
chair, spring return; automobile shock absorbers and springs; elevators going
down (flywheels are sometimes implemented here); any kind of cyclical
process where energy is 'used' to create potential energy or dissipate
kinetic energy ... if the technology is developed and cheap, it could go
anywhere.</FONT></DIV>

say the tile deflects 1mm under one foot. Therefore the spring constant k

is just EPE stored by the tile whilst loaded. The tile will probably consist
of the piezo device and a substrate which the energy will dissipate over.
Let’s be generous and assume 20% of that work is converted to electrical
energy. We are now talking about 0.034 Joules per foot fall. The rest will
escape as heat. Considering a human metabolism whilst walking will be of the
order of 120 Watts plus (Watts = Joules / second) the energy recovered
through floor tiles would be minimal.<O:P></O:P></SPAN></P>
