This thing is, seriously, the highlight of CES for me (so far) this year. 3D TVs and eBook readers are fine, but there's nothing amazing about them.\n\nThe Airnergy Charger is amazing.\n\nThis little box has, inside it, some kind of circuitry that harvests WiFi energy out of the air and converts it into electricity. This has been done before, but the Airnergy is able to harvest electricity with a high enough efficiency to make it practically useful: on the CES floor, they were able to charge a BlackBerry from 30% to full in about 90 minutes, using nothing but ambient WiFi signals as a power source.
Top mobile telephone suppliers have agreed to back an EU-wide harmonisation of phone chargers, the European Commission said on Monday, hailing the pact as good news for consumers and the environment.
The Commission said the agreement would involve the creation of an EU norm, and that the new generation of mobile phones would use a standard micro-USB socket to ensure compatibility.
