Introduction

Hearing the concerns about global warming and knowing our dependency on fossil fuels the solar roadways imagined to develop roadways with solar panels.

Solar roadways technology will replace all current petroleum-based asphalt roads, parking lots, and driveways.

INVENTORS OF SOLAR ROADWAYS

Julie & Scott Brusaw

Solar Roadways

A solar roadway is a road surface that generates electricity by solar power photovoltaic cells embedded below a tough transparent surface which provides sufficient traction.

Solar Road Construction

A solar roadway consist of three layers: Road surface layer/Glass layer Electronic layer Base plate layer

1.Road Surfaces layer/Glass Layer

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.

2.Electronic Layer

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.

3.Based Plate Layer

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.

Based Plate Layer

Illuminated Highway

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.

Intelligent Highway

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.

Central control stations will be able to instantly customize the lanes and words on the panels as like screen, reducing traffic congestion.

On-The-Go Charging

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.

Road Survey Of India

India has a road network of over 48,65,000 kilometers in 2014.

In which national highways and state highways cover 5% of total road network.

These highways can produce 450TWh of electricity according to references when they are surfaced by solar panels.

But India needs 991TWh of electricity.

This implies that if 10% of total road network of India is surfaced with Solar Roadway panels, it would illuminate our nation.

Future Scope

EVs will be charge with energy from the sun(instead of fossil fuels) They pay for themselves primarily through the generation of

electricity. A nationwide system could produce more clean renewable energy

than a country uses as a whole.

Conclusion

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.
