Hello everyone, today we are going
to talk about “Think Different to Develop Green Technology”.
Do you know what innovation is?
Of course, many people have heard about it very often.
But did they really know this word correctly?
It is easy to mistake that innovation is invention.
But that’s not the case.
Innovation contains invention,
but iteration which advances what is already there is also innovation.
That means;
we can innovate through iteration.
We try to solve the problem caused by climate change through iteration.
Increasingly, climate change is causing problems all over the world.
Drought has occurred in the UK due to the heat wave and dry weather,
and France is suffering from major forest fires.
There was also the first heavy rain in 1000 years in the United States.
Green algae are also the result of climate change.
Microcystin contained in algae cause fatal liver damage,
which means that algae caused serious damage to humans,
as well as underwater ecosystems.
In addition,
some rivers are also used as drinking water,
so if they are contaminated with algae,
there is a risk that humans will directly consume algae.
There have already been reports of deaths of livestock,
fish, and humans from algae in many countries.
As such, the damage caused by green algae is serious,
but there is no clear solution.
Currently, light source brain water circulation,
and hydrogen peroxide treatment are used to lymph algae.
However, these muscles have problems such as breast damage,
not just First damage,
environmental pollution and active oxygen generation.
So, we came up with a method of removing algae through iteration.
The idea we developed through iteration is proposed by a child
“Hong Jung” who appeared on a program called “Finding Genius”
process of the speaker device for removing algae.
it requires less manpower and cost,
because it moves from its own through solar energy
We are able to get the idea from this,
In order to develop this sector more respectively,
we create large and small spheres,
So that the double structure could more effectively separate the algae.
But there is also a problem.
It breaks down green energy with hydrogen peroxide which creates active oxygen,
and threaten the aquatic ecosystem.
Looking for a solution For this,
we found electrical aggregation technology.
In 2017, the “Korea Institute of Machinery and material
removed 99% of the energy through electric aggregation technology.
We conducted a server experiment with different electrodes
to make better use of this research.
As a result,
it was efficient when using aluminum electrode,
We came with a device that replaced
from child’s idea of using hydrogen peroxide
to using electrical aggregation, And we built a prototype.
“Elec” this device removes our digital electrical aggregation technology,
in a spherical battery with electricity obtained from solar power.
This is how it works.
First, electrical aggregation of course occurs in a smart pair inside the device,
separating the Rg and the water,
and through the passage between the smallest pair and the largest pair,
and zero the passage between
The filtered water is drained out
The filters are deflated on the surface on the spherical water,
the oculate Rg will be collected periodically on land.
By adding these two small ideas,
we were able to find ways to eliminate Rg,
or continuously by minimizing them pass without affecting the environment.
We will add another idea to the device,
to further reduce the manpower used to remove algae.
We try to increase the size of the device to increase the cycle of collecting algae.
And to add on work on the factory,
we have a plan to design this device as a landmark,
like a rubber duck on the “Hong Kong River”.
If we make this device large and design friendly to people,
it will kill two birds with one stone,
because it not only reduces the cycle of collecting algae,
but also looks good.
In this way, we designed a new way
to solve the algae problem through iteration.
Do you still think invention is the only answer of innovation?
It’s been said that while this may Silicon Valley is so successful,
isn’t the invention but the iteration nature of how they work.
There are already many technologies and inventions that have been developed,
and it's time for us to try to improve them through iteration.
Just as we came up with a new way of removing algae.
You should try innovation through iteration.
Thank you.
