Question

How to make a working model on energy from waste for my science homework?

Answer 1

Make a solar cooker from aluminum cans.  You have to cut and join them together to make a parabolic reflector.  Hope you get an "A" for your work.  Good luck.

Answer 2

Most energy from waste models require the burning of or otherwise using the heat from decomposing material to generate power.

You could in theory create a small compost container and put a very precise thermometer on it to show that heat is generated by the bacteria doing its' job.

You might also try to harness the heat to spin a tiny turbine or fan and generator to light a small bulb then explain how it works on a much larger scale.

I would love to see a micro methane extraction system with a tiny flame but I am sure there are rules about generating and burning gases during a demonstration at school :)
