#PROBLEM/MOTIVATION

Although big garbage dumpsters have enabled convenience to the residents of the apartment, there are big issues to the conventional use of these dumpsters. The first problem is that residents often stack the garbage to the point it overflows, thus making a big mess nearby the dumpsters. The second problem is that because it’s open in use for everyone, people who aren’t necessarily the residents of these apartments use these big dumpsters to save their money on garbage. This makes it difficult for the people who actually pay for these services to enable the full benefits of what they pay. The third problem is that because these big dumpsters are so big, it is often difficult for many people to open and close these dumpsters. Therefore, it is often hard for women or elderly people to have the full convenience when throwing their garbage out. The fourth problem is that because these big dumpsters are not locked, when garbage trucks lift these dumpsters, there are often wastes that flow outside the back of the garbage truck and make mess. Lastly, whenever these bins are full, the people simply don’t know whether the dumpsters are full until you get to the dumpsters, making the action of going to the actual dumpster and walking to that place useless.

# SOLUTION
For all these solutions listed below, we will be using an app that will allow easy access.

- Enabling a sensor in the garbage can that allows the residents to know when the garbage is full or not, and if when full, automatically locks it so that people don’t stack them on top.

- We are going have a lock and unlock feature in the dumpsters that will allow only the people who pay for the garbage service to use them.

- We are going to create an open and close system where the residents simply need to use their phones to open or close the dumpsters automatically.

- We are going to have a map system where the apartment users can track which dumpsters are full or not. If the nearest one is full, then they will be able to check the dumpsters from other areas in which they can throw their garbage to.

- We will make all these dumpsters self-sufficient by enabling a solar-powered battery that doesn’t need to be recharged to have these systems work.

# CRITERION FOR SUCCESS

- Easy UI for people access these features
- Strong Protective Components that won't break when people throw garbages
- Working lock/unlock mechanism and automatic open/close mechanism

El Durazno Wind Turbine Project

Featured Project

Partners: Alexander Hardiek (ahardi6), Saanil Joshi (stjoshi2), and Ganpath Karl (gkarl2)

Project Description: We have decided to innovate a low cost wind turbine to help the villagers of El Durazno in Guatemala access water from mountains, based on the pitch of Prof. Ann Witmer.

Problem: There is currently no water distribution system in place for the villagers to gain access to water. They have to travel my foot over larger distances on mountainous terrain to fetch water. For this reason, it would be better if water could be pumped to a containment tank closer to the village and hopefully distributed with the help of a gravity flow system.

There is an electrical grid system present, however, it is too expensive for the villagers to use. Therefore, we need a cheap renewable energy solution to the problem. Solar energy is not possible as the mountain does not receive enough solar energy to power a motor. Wind energy is a good alternative as the wind speeds and high and since it is a mountain, there is no hindrance to the wind flow.

Solution Overview: We are solving the power generation challenge created by a mismatch between the speed of the wind and the necessary rotational speed required to produce power by the turbine’s generator. We have access to several used car parts, allowing us to salvage or modify different induction motors and gears to make the system work.

We have two approaches we are taking. One method is converting the induction motor to a generator by removing the need of an initial battery input and using the magnetic field created by the magnets. The other method is to rewire the stator so the motor can spin at the necessary rpm.

Subsystems: Our system components are split into two categories: Mechanical and Electrical. All mechanical components came from a used Toyota car such as the wheel hub cap, serpentine belt, car body blade, wheel hub, torsion rod. These components help us covert wind energy into mechanical energy and are already built and ready. Meanwhile, the electrical components are available in the car such as the alternator (induction motor) and are designed by us such as the power electronics (AC/DC converters). We will use capacitors, diodes, relays, resistors and integrated circuits on our printed circuit boards to develop the power electronics. Our electrical components convert the mechanical energy in the turbine into electrical energy available to the residents.

Criterion for success: Our project will be successful when we can successfully convert the available wind energy from our meteorological data into electricity at a low cost from reusable parts available to the residents of El Durazno. In the future, their residents will prototype several versions of our turbine to pump water from the mountains.
