The idea of
decorating rooftops with solar panels has been around for a while, but an
international team of scientists came up with a new concept of using artificial grass to generate energy. Apparently, synthetic fibres can work as a miniature
wind turbine, producing power for the home with every breeze.
The
turboelectric generator (TENG) uses strips of artificial grass to generate an
electric current. One side of a fiber blade can be coated with nanowires while
the other with indium tin oxide. As the wind blows, fibers come into a contact
with each other. It allows electrons to pass from one piece of grass to the
next, generating an electric flow.
The principle
behind it called a triboelectric effect. It’s a type of electrification in
which different materials (a comb and hair, grass and fur) come into a
frictional contact, and build up tribo-electricity. It’s almost like a chemical
bond. Dissimilar molecules exchange electrons.
It can work
extremely well in areas when the wind direction changes frequently, or location
where windmills are ineffective.
According to
scientists at Georgia Tech, 60 strips of artificial grass produce enough
electricity to power 60 LED lights. The aftermath predicts that the 3230 sq.ft.
rooftop will generate approximately seven kilowatts of energy; enough to power
an entire home independently.
The concept is
promising, but first, the scientists need to find a cheaper and safer
replacement of indium tin oxide, which is toxic and should not be inhaled sense
it causes mild irritation in the respiratory tracts.
Another question
is still in an open: how to capture free electrons produces by electrification
of synthetic fibers? With the provolcanic cell technology (the direct
conversion of light into electricity at the atomic level) getting more advanced
every day, it’s possible to combine synthetic grass with solar panels placed on
rooftops. Imagine a green, beautiful rooftops that generate
clean, affordable, infinite, renewable wind and solar energy to meet a power
demand! Artificial grass can be an answer!
