Alex the Polar Bear’s Power Station

Overnight, a strange and super cool invention appeared in Gadgetville, built by Alex the Polar Bear.  Alex the Polar Bear is an extremely gifted inventor: his new invention generates electricity from four different energy sources: solar energy, wind energy, water energy and muscle energy. Electricity is always needed, and Alex’s invention works without a hitch. Because if there’s no sun, there is rain, and if there’s no rain, there is wind, and if there’s neither sun, rain nor wind, there is always strength in our hands. The villagers can now come to fetch electricity and, if needed, fill their buckets to the brim. There’s plenty of it to go round!
