Final thoughts
Managed to build a working prototype and display proof of concept.
Meets essential requirements of functional specifications.
We actually learned something – on a technical perspective and on a business perspective
There is a potential for our product. There is a huge market for greener technologies. Responsibility as engineers and as a people to look after our environment.
