Solar roadways generate electricity through photovoltaic cells embedded below a glass surface. They consist of three layers: a glass road surface, an electronics layer to collect solar energy and distribute power, and a base plate layer to protect the electronics. In addition to generating electricity, solar roadways could illuminate roads, display instructions to drivers, and wirelessly charge electric vehicles. While initial costs are high, proponents argue solar roadways could eventually have similar costs to traditional roads and power plants while providing renewable energy and safer transportation.

3. What is Solar Energy?
Solar energy is the light and radiant heat from the Sun that
influences Earth's climate and weather and sustains life. By
using this energy electricity can be produced with help of
solar technology.
Solar technologies are broadly characterized as:
Active solar technology
Passive solar technology

5. Solar energy is preferable as compared to another energy sources due
to following reasons:
Reduced Dependence on Fossil Fuels
Environment friendly
Matching Peak Time Output with Peak Time Demand
Modularity and Scalability
Flexible Locations

Solar Street Lights Solar Water Pumps

7. Why Shouldn’t THINK BIG
Step forward to Solar Road Ways

8. A solar roadway is a road surface that generates electricity by solar
power PHOTOVOLTAIC CELLS embedded below a tough
transparent surfacewhich provides sufficient traction.

9. A solar roadway consist of three layers:
Road surface layer/Glass layer
Electronics layer
Base plate layer

10. Translucent and high-strength, it is rough enough to provide sufficient
traction, yet still passes sunlight through to the solar collector cells
embedded within, along with LEDs and a heating element.

11. It contains photovoltaic cells which absorbs solar energy. It also contains
a microprocessor board with support circuitry for sensing loads on the
surface and controlling a heating element with a view to reducing or
eliminating snow.

12. While the electronics layer collects energy from the sun, it is the base
plate layer that distributes that power as well as data signals (phone, TV,
internet, etc.) down the line to all homes and businesses connected to
the solar roadway. It needs to be weatherproof to protect the
electronics layer above it.

13. Renewability
Life-span
Road Illumination
Intelligent Highway system
Military and rescue assistance

14. Maintenance costs
Seasonal efficiency
Needs a town planning
Initial Cost

15. The power lines and data lines running over the poles,
Make the city ugly
Interrupt to the way of vehicles
Hacking of trees is required when they come in the way of lines

16. This can be avoided by encasing these power lines below the Glass layer
which can be directly supplied by electricity form there itself with no
loss of energy due to electric resistance. This will eliminate all the
drawbacks of ‘power lines hung on poles’ and also ensure safety.

17. Many people driving their vehicle at night cannot see the road ahead
due to oncoming headlights or rain.
The Solar Roadways will have LEDs which will illuminate the lanes.
Thus the rate of accidents will be reduced and illumination of roads
will add to the aesthetics of the city.

18. The LEDs can be programmed to show the instructions such as - SLOW,
STOP, GO, SPEED LIMIT, etc.
The LEDS can also be programmed to warn drivers of an animal on the
road, an accident, or construction work.

19. With induction plating embedded
inside these roads, electric cars
can be recharged while in motion
on top of these roads. This would
reduce the costs and the time-
inconvenience of waiting at a
charging station.
Another option available for
charging is stand-by charging
which is done by plugging in the
charger in the slot vehicle, this
method can be applied when the
vehicle is parked in the parking
lot.

SCOTT BRUSAW AND JULIE BRUSAW

22. For roughly the same cost of the current systems (asphalt roads and
fossil fuel burning electricity generation plants), the Solar Roadways can
be implemented.
No more Global Warming.
Safer driving conditions.
Far less pollution.
A new secure highway infrastructure that pays for itself.
A decentralized, self-healing, secure power grid.
No more dependency on foreign oil.
