Hello, we are from the school Gonzalo Fernando de Córdoba and our project is called Green Hydro Ship. 00:00:00
Recently, we've been experiencing a great energy crisis. 00:00:06
Every day, light and oil prices rise. 00:00:10
We don't want to continue like this. That's why we have been investigating the issue 00:00:14
and we have discovered that the cargo ships that transport the goods from one continent to another 00:00:18
are the most energy consuming method of transport. 00:00:23
Additionally, we have seen that the most abundant element on the planet is hydrogen. 00:00:27
So why not use hydrogen as a source of energy? 00:00:32
Taking all of this into account, we decided to build a ship using our 3D printer. 00:00:35
We had to make various prototypes until we developed the ideal model. 00:00:40
One problem that we had was letting our ship to float. 00:00:44
We already knew that the PLA is very porous and it ends up sinking when we put it in water. 00:00:47
so we applied a special coating to the base to allow our ship to flow without problems. 00:00:53
Later, one of the things that we took into consideration was to investigate how to propel a ship. 00:01:00
Upon investigating, we arrived at the conclusion that the best way of movement is using paddles of this type. 00:01:06
In this manner, we could easily collect water coming into the ship, 00:01:13
disachieving hydrolysis to produce hydrogen in a simple way. 00:01:16
It's true that no one has been able to produce hydrogen with salt water, but thanks to the 00:01:20
DAI research at Stanford University, there has been significant advancement in this. 00:01:25
They found out that if they covered the anode with layers reaching negative charges, these 00:01:32
layers would reduce the metal-less compulsion in the anode. 00:01:38
That prevents the salt water components from breaking the submerged anodes. 00:01:42
Our ship will have a fuel cell, like the one you see here, that has two functions. 00:01:48
The first function is electrolysis, generating hydrogen and oxygen from water thanks to the 00:01:54
solar panels. 00:01:59
The hydrogen and oxygen are stored in cylinders thanks to the cables that we have connected 00:02:01
to a solar panel that produces electricity using the electrodes. 00:02:05
The current that passes through the negative terminal collects hydrogen and the positive 00:02:10
terminal collects all oxygen. 00:02:15
The second function is hydrolysis, where a fuel cell generates electric energy through 00:02:19
the reaction between the stored hydrogen and oxygen. 00:02:23
In this process, the positive hydrogen charges are combined with the oxygen-forming water 00:02:27
vapor that will be the only waste generated, whereas the negative charges continue to circulate 00:02:32
through the battery producing the electrical current that moves the ship. 00:02:38
Here you can see our ship working. 00:02:41
We have created an app with App Inventor and we drive our ship using the app. 00:02:44
We had also so much fun! 00:02:49
With this system we can get our ship to function with clean energy and that respects the environment 00:02:52
as proposed on the 2030 Agenda. 00:02:57
