Piezoelectric materials can harness vibrations and
pressure from passing cars and convert that energy into
usable power. In 2008, a rail station in Japan used
piezoelectrics in its floors to take advantage of the
vibrations from footsteps, generating enough power to
run holiday displays. In 2009, an Israeli company
tested these materials in a 10-meter strip of road
and reported generating an average of 2,000 watts,
enough to theoretically power 30 60-watt lightbulbs.
And now, the California Energy Commission is currently
studying whether piezoelectric materials will be
economically feasible to use on the state’s roads.
Daan Roosegaarde, founder of international design lab Studio
Roosegaarde, based in the Netherlands, has another
energy-saving idea: roads that glow. With the help
of engineers from Heijmans, one of the largest road
builders in Europe, he and his designers developed
a highly photo-luminescent paint for delineating
lanes that charges enough in sunlight (even on cloudy days)
to glow bright green for up to 10 hours at night.
Roosegaarde plans to build a 300-meter-long
prototype road to demonstrate both the glow-in-the-dark
paint and another paint they’ve developed—one that
changes from transparent to blue as the temperature
drops below 32°F to warn drivers of icy conditions.
Other untested ideas go further: lights that switch
on as a vehicle nears and roadside wind turbines
propelled by updrafts from passing cars.

The piezo device is stealing. The energy gained is energy stolen from the car.
The conductive pen. Similar to the conductive paint i use on circuit boards. Wait till the kiddies discover they can hot wire a car with a pen
At Notre Dame, professor of chemistry and biochemistry Prashant Kamat led a group that found a mixture of nanometer-sized titanium dioxide particles, coated with either cadmium sulfide or cadmium selenide and suspended in a water-alcohol mixture to create a paint-like paste that generates electricity when exposed to light. They gave it a name: Sun-Believable.
the technology is to help U.S. troops avoid navigational mishaps on military missions. It is meant to kick into gear when GPS is temporarily down or unavailable--it is not designed to replace GPS
I wonder if they might use this as a 'failsafe' method in spys, sort of an auto destruct should they go rogue, or be captured?

But a car engine is giving out a lot of energy in ways that don't contribute to the motion of the vehicle. The engine can be heard, the motion of the pistons is creating vibrations in the body of the car. So that energy is already lost.
