Energy from vibration

I've thought off and on for a while about
how much energy is wasted in vibration of
engines, and finally Googled it.  A sampling
of the results:

Microgenerator uses vibration to produce energy

Energy efficient vibration driven motor

Energy sinks: Vibration absorption by an optimal set of undamped  

Distributed Energy:  What you need to know about noise and vibration

New Vibration Powered Generator For Wireless Systems

There are also advances in generating energy
from body heat, car exhaust, ambient light,
rain, etc.  As these technologies generate
energy more efficiently and devices require
less energy to run, more and more devices
will be able to function without batteries
or electrical connections.    Have we got a
prediction yet for when the last lead-acid
battery will be produced?

Could microwave ovens be made significantly
more efficient by using lenses to focus the
microwaves on the food?  Energy to do the
refocusing should be easy to come by soon.

   You needn't ever launder off the dirt
If you possess two shirts to choose between
   and always change into the cleaner shirt.
