General Motor's Joint-Venture partner in China, Shanghai Automotive Industry Corporation (SAIC) rolled out a concept alongside GM's EN-V at Expo 2010 which in many ways is more ground-breaking than the EN-V. The idea behind the YeZ Concept is that it will photosynthesize, absorbing carbon dioxide from surrounding air and emitting oxygen back into the atmosphere. Among the many futuristic aspects of the YeZ (Chinese for “leaf” as Nissan already uses the name for a clever green concept that is heading for production) is a roof that incorporates solar panels and wheels that incorporate small wind turbines to harvest energy from the environment. And if you think this is not within reach by 2030, think again – artificial photosynthesis has proven elusive, but there's every indication it will be a commercial reality within two decades.
Jawbone, a company better known for its Bluetooth headsets, has now released a Bluetooth speaker system that makes use of two powerful acoustic drivers and ultra-small speakers that work in concert with an innovative moving-wall passive bass radiator and airtight enclosure. The company says this is the first time this technology has been seen in a personal speaker system and delivers more punch than you'd expect from such a small unit.

Because battery technology hasn’t developed as quickly as the electronic devices they power, a greater and greater percentage of the volume of these devices is taken up by the batteries needed to keep them running. Now a team of researchers working at the Center for Integrated Nanotechnologies (CINT) is claiming to have created the world’s smallest battery, and although the tiny battery won’t be powering next year’s mobile phones, it has already provided insights into how batteries work and should enable the development of smaller and more efficient batteries in the future.
