Project goal

Recycle a old household water heater and an old school chair and turn them into a parabolic concentrated solar water heater

Project steps:

  1. Model full scale design
  2. Model and build a 3-D printed small scale prototype
  3. Test effectiveness of design based on prototype
  4. Build full scale solar concentrator
