It hardly seems like we’re weeks away from the fourth anniversary of the Fukishima nuclear disaster following the Tsunami in March 2011, but it is far from erased from the Japanese psyche as visitors to the Smart Energy show in Tokyo (incorporating battery Japan) would have noticed.
Being without electricity has stimulated a market for “Doomsday Preppers” in the form of home, office and larger power back up systems.
Such products include this Magnesium air battery (pictured) from Furukawa— best known to BEST readers for its work on commercialising the Ultrabattery concept.
The Magnesium air battery just needs water to activate it as this picture shows. Once four litres of water are added to the box, electricity is generated in about two minutes so users can recharge cell phones and similar devices, through its inbuilt USB power converter.
Picture: And don’t forget the ice and lemon………
