Roof Tops or
Highways ?
------------------------------
To generate 1 Kw of
solar power you need , approx. 10 Sq Meter
( 100 Sq ft ) of roof top
So , if you want to generate 817 Kw , you would need 8,170 Sq Meter of flat roof
But the Chinese have just managed to
generate 817 Kw , using only 5,875 Sq Meter space
And , that too , on the highway
surface ! In 28 % less area
as compared to Roof Top
But the breakthrough has nothing to do
with mere reduction in area
It brings the World , one step ( -
actually , one Km ) closer to :

Reverse Toll ? Possible [ 07 May

China successfully tests its first photovoltaic highway

Roads with solar panels are no surprise.
But a road with built-in wireless charging
systems for electric vehicles and other
sensors for drones is surely taking things to the next
level and looks like China has successfully achieved that feat.
According to Xinhua, China has
successfully tested its first photovoltaic
highway based on home grown technology, in the country’s eastern
Shandong province.
The road is constructed using solar
panels which have a thin sheet of clear concrete on top, protecting the
surface. The panels were built to transfer
energy to electric vehicles passing on top of them.
The one
kilometer-long segment of the solar-powered highway covers a surface
area of 5,875 square meters.
The special section has three layers.
The bottom is an insulator to prevent moisture from getting to the photovoltaic devices in the middle. At the top
is the protective, transparent concrete layer.
The tested segment of the highway can
generate 817.2 kW of power and is
expected to generate 1 million kWhr of
electricity each year.
The electricity generated through this
will be connected to China’s national power grid.
China becomes the second country to
construct a photo-voltaic highway.
In late 2016, the world’s first photovoltaic road fitted with solar panels
debuted in France.
Shri Gadkriji may want to challenge ISRO /
