Making cell phones takes a lot of materials and tools. Senku begins by upgrading their equipment using the waterwheel Chrome and Kaseki invented and built together.
All our precious electricity 
is still leaking away.
.كهرباؤنا الثمينة تتسرب في كل مكان
Denn unsere wertvolle Energie
entlädt sich noch ins Nichts.
Toda esa valiosa electricidad se pierde.
Esta preciosa electricidad
se desperdicia.
Le précieux courant électrique
est diffusé dans le vide.
Continua a perdere e spargere ovunque
la sua preziosa elettricità.
Toda a nossa preciosa 
eletricidade está fugindo.
Наше драгоценное электричество
идёт в никуда.
