In the five months since a tsunami and 9.0 magnitude earthquake hit Japan, we've seen various technology companies struggle to get their manufacturing operations back in order, but Sony appears to be the first to introduce a product seemingly inspired by the disaster itself. The outfit's Japanese division just announced the ESSP-2000, a 90kg (198-pound)battery whose 2.4kWh of power should keep businesses and government agencies afloat for at least a few hours in the event of a blackout or natural disaster. All told, the battery can support a maximum load of 1000VA, and can recharge to 95 percent in about two hours -- not bad, considering the capacity of this thing. Sony also went with olivine-type lithium-ion iron phosphate batteries, which it says will last ten years. With a price of ¥2 million ($25,700), this battery's clearly not meant to be a savior for home users, though for businesses it could be a small price to pay for an uninterrupted power supply.
