for my science class, we’re carrying out a challenge for substitute energy sources. and we are essential to make a non-working design for a single of these sources of vitality: photo voltaic, biomass, hydro electricity, geothermal, wind, and hydrogen.
we have to make a 3-D design/exhibit of the subject (power source) we decide on. but it won’t have to operate.
my query is, if anybody had any ideas for this task?
like what could i make a model of?
