hey guys this is Zi Hao and this is my
moonshot idea
so to salvage and repair our planet I have
actually came up with an idea of using a
hybrid energy harvesting tool - which uses the
concept of piezoelectric and seebeck
and also photovoltaic effect so for the
six sides of the cube there will be mini
solar panels piezoelectric crystals and
also peltier tiles which generate voltage
when there is a temperature difference
for piezoelectric crystals when there's
mechanical stress applied on a surface
there will be voltage produced as well
so at the center of the cube there's
actually a capacitor to store energy
obtained from the devices so it actually
acts like a power bank but
it is more environmentally friendly and
also cheaper to build so for people for
underprivileged people in Africa
especially these devices can be made it
can be easily made accessible to all of
them because it is very tiny and
compacted and although the energy
harness may be trivial but imagine
having thousands of them having millions
of them we can actually save a lot of
energy to power our electric electrical
appliances like a flashlight our phone
and and now I will show you my prototype
and here are the main components being
explained here and we will head to the about
page so here is the explanation about Peltier
tiles we can actually held in our hands
because there will be a temperature
difference and for piezoelectric crystal
there there are actually a lot of
interesting information as it can
be powered by footsteps because you're
actually stepping on it and there will
be mechanical stress as I mentioned it
thank you
