Wired: Have you ever been in desperate need of an AAA battery (your TV remote control is running out of power) and all you can find in your house are AAs or some other incompatible size of battery?
Three designers claim to have the solution. Pyeong Joo Goh, Jong Seung Choi and Ji Soo Hong have created the AtoD rechargeable battery, which can be squashed to fit the device that you need to power.
The battery is made from memory foam and so will retain its shape until you squash it for a different device.
It will then gradually become bigger again when you remove it for recharging. It provides 1.5 volts of nickel hydroxide power, but there’s no indication of whether it will make it beyond the concept stage.
