Rich, I was just thinking of

-       Splitting group into 2
-       One person using light bulbs, electric fire to keep warm etc, boiling water 
for tea etc, rest of class trying to generate the power required (depending on age 
and strength) with handpowered cranks
-       Then think of solar / wind, try that
-       Then think of energy storage to help out

        -       A damn (or pumped storage hydro)
        -       Gravity (https://www.gravitypower.net/)
