We were assigned a task to create an energy-transferring device within 2 weeks.

Project ideas:

Elastic propeller car-

Challenge rating out of 5: ⭐

Skills used: Gluing wood and elastics, creating models with fusion

  • Pros: the project would be very simple to make
  • Cons: there would be some trouble finding the fan involved, but Fusion or Tinkercard could be used to create it.

The video clearly shows how to create this propeller car, and I could use this video as a guideline while making my own device.

Audience: This device is more like a toy, so it could be targeted towards kids, adults, or anyone who just wants to have some fun.

Solar updraft tower-

Challenge rating out of 5: ⭐

Skills used: Gluing paper

  • Pros: The project would be very simple to make
  • Cons: It could be a bit difficult to find a lamp as this project is reliant on heat energy to make the fan move

The video provides materials and detailed instructions for building a solar updraft tower.

Audience: This device doesn’t have much practicality but could be targeted towards kids or adults who want to see how heat energy can lead to kinetic energy

Solar plant watering-

Challenge rating out of 5: ⭐⭐⭐⭐

Skills used: Soldering skills, gluing skills, knowledge of solar panels

  • Pros: It’s more practical and could be used in real-life situations. The video shows how to make it very clearly.
  • Cons: The materials could be slightly challenging to find. Additionally, the video doesn’t provide a list of materials used, which could add to the difficulty of finding materials. However, there is a switch involved, and if this were to be used with natural plants, the user would need to add water. 

Audience: This device could be for people who want to water their plants but easily forget to. Solar energy would help them water their plants.
