RE projects for technology courses
RE projects for technology courses
I'd like to start a forum discussing interesting projects in that teach about renewable energy as a technological centerpiece. Please reply if you know about any good projects.
Solar recharged power lawnmower
Appropedia is an excellent site for technological innovations, mostly on the scale of an individual's work:
http://www.appropedia.org/
One example is the Solar Charged Lawnmower, a car-battery powered lawnmower.

It seems like such a good idea, since the more sun a lawn gets, the more the grass grows, and the more the PV panel charges the battery. I would turn it into a lesson about right-sizing the electric components (motor, panel, battery). It seems from the article that the author manifested physics-learning in his discussion of sizing.
Appropedia also includes an article about a solar food dehydrator, which explicitly describes an engineering process:
