Aquatic Life Saving Building

Welcome to the Aquatic Life Saving Building (ALS-b). This design was inspired UN SDG Goal #14 – Life Below Water.

This building is half under water and is supposed to be built near the large city of Athens. The purpose of the design is to use ultra- violet laser technology to detect and alert authorities about illegal fishing boats and nets in the Mediterranean Sea.


In addition, it can be as a lab for scientists to study endangered fish (like the European Sea Sturgeon), which they can also use the UV laser readings for (fish cannot see UV light).

This building’s power supply is provided by geo-thermal energy (you can see the power plant on the shore of the design), which works with Goal 7 – Affordable and Clean Energy and Goal 11 – Sustainable Development.

This building is also used as a homeless shelter – this goes with Goal 1 – No Poverty, because it will be placed near large cities where there are more people than there is housing. There is a bridge that connects this building to the shore, so that the people can go to work or the store.

I see this building in a future city because population will grow and more homes will be needed, and more people may lead to more overfishing. This building can help to stop overfishing in a sustainable way. That is why my project connects to future cities and the UN Sustainable development goals.

Dehumidifying Water Filter

I created a dehumidifier with solar panels, a sink, and a tap, which applies to the UN SDG for clean water and sanitation (#6).

My dehumidifier takes the water from the air and filters the water so that it’s clean. The clean water can then go in the tap and the person who is waiting can fill their water bottle with clean water.

If the water spills from the water bottle, it ends up in the sink. There is a pipe that takes the water from the sink and filters it again so that it can be used a second time and not be wasted. The energy from the solar panel is used to draw in the water from the sink back into the filtering system.

One important design from my invention is the solar panels. They are important because it’s the energy from the solar panels that provides the energy needed to allow the tubes to draw in the water that hasn’t been used.

Supreme Food Machine 2000

Hunger is a very important issue in this world. Many people starve every day, without the ability to buy fresh and non-contaminated food.

To help reduce hunger, I created the ‘Supreme Food Machine 2000.’ At the left side of the machine is the Food Donation Box, in which only canned food could be accepted. The donations would soon be the food provided to those starving from hunger and who wish to receive food from the machine. Water bottles could also be received from the machine.

On the right side, there is a ticket machine. People that are hungry need to click the red button to receive a ticket, which they will use to get food from the machine. They put the ticket in the slot of the machine and either click the Water Bottle button or the Food Slot button to receive their choice.

The food would be checked weekly and changed as well. These machines would be put in public places to help people fill their hungry stomachs.


Piezoelectric Treadmill

My design is a treadmill that converts kinetic energy into electrical energy using piezoelectricity. That way, electricity is being made while getting physical activity.

My design addresses both SDG #3 (Good Health and Well Being) and #7 (Affordable and clean energy). While getting more physical activity, you reduce the risk of getting heart disease as well as produce cheaper electricity for the household.

One important part of my design is the computer that keeps a tally of how much time has been spent daily on the treadmill for each person.


Magnetic Solar Car

This is my futuristic car. This car supports the 11th UN SDG of Industry, Innovation, and Infrastructure.

The way I created this car is using hovering wheels. I believe in the future that cars will hover by making magnetic plates inside the roads. The wheels should be attracted to the magnet but not fully, making it hover.

The pieces on the top are solar panels. The solar panels are there to take power from the sun and charge the car battery so it can move. Just in case, I wanted it to be an electric car so it can charge without using fuel which also is good so it doesn’t cause as much pollution.

About The Contest

  2. Participants can work through the course at their own pace; feel free to use the course in your class in any way that makes sense to you! 
  3. Once participants have built their skills, they’re ready to create their own unique project. Participants will also need to submit a short (less than 250 words) description of their project and how it solves the problem.  
  4. Students can submit their projects any time between 12:00 pm EST on June 28, 2021 and 11:59 pm EST on August 13, 2021. Only one submission per participant will be accepted.  
  5. Using this rubric, our judges will narrow down all submissions to the top 5 best projects. The top 5 finalists will be announced on August 23, 2021 at 12:00 pm EST. 
  6. The top 5 projects will be shared for community voting until August 29, 2021 at 11:59 pm EST.  
  7. The votes will be tallied for each of the top 5 projects and the first-place winner will be announced at 12:00 pm EST on August 30, 2021.
