This Young Scientist Is Bringing Cheap Electricity To Those Without It


For over one fifth of
the global population, this darkness is
a permanent reality, and I wanted to
make a difference. The ultimate goal is
to actually deploy Harvest so people across the world, especially in
Third World countries, can have access to electricity. I started off by experimenting
with this piezoelectric effect, and it’s just this one energy
harvesting phenomenon. They produce an electrical charge when applied with some form
of mechanical stress. Harvest was definitely not
one of those “light bulb moment” type ideas. I realised, what if we could apply
this piezoelectric effect to not only harvesting
direct mechanical stress of, like, people’s footsteps but also in direct mechanical stress
such as the wind itself, and that’s when I decided to apply
the piezoelectric effect with wind. It can be used, like,
kind of like solar panels to kind of integrate
renewable energy harvesting into the urban landscape. Having more efficient
piezoelectric materials, that can definitely improve
the power output and make it more scalable. The next issue is actually funding
and scaling and finding that perfect partner to really make sure
it reaches people. Initially while starting off, Harvest produced very,
very low amounts of power. At that time,
I could have easily given up, and I was losing hope by that point, because obviously I wanted
to create something that could be practical
and applicable to people. But I kept on going. Just go for it, because there is a lot of issues
we sometimes face. We might not be confident
in ourselves, and other people might not even be
confident in you, but the main thing is
you’ve got to believe in your idea, and at least try. Whether that’s through building
a prototype with household materials or just sketching out an idea. I think it’s really important
to take a shot for it, because you never know what
difference it can make.
