dieser taschenrechner braucht nur wasser um strom zu erzeugen. also regelmaessig giessen und schon kann gerechnet werden. grosse tasten und ein ergonomisches design runden das konzept ab. darueber hinaus ist er gar nicht mal so teuer, nur $24.95. mehr informatione zum wasserbetriebenen taschenrechner gibts in englisch:
