WHEN YOU ARE TOO LAZY FOR A REAL PET

Check it, the brains at the Faculty of Engineering at Osaka City University have come up with a robotic fish that can swim around the tank powered by just a solid-polymer fuel cell, dubbed the “Power Tube”. The 10cm long robotic fish can swim, as well as dive and rise, owing to a joint at the front end of the fish. Initially the idea was to use a motor to get this little fish alive and kicking (swimming), but when they found out that the power consumption was about 1W, they switched to a magnet system that reduced the number to just 10mW. Now I never have to worry about killing my goldfish.
