Considering Scotland's determined renewable energy development, Gaberlunzie reckons one element where  more work is need is quite simply on energy storage as batteries leaving much to be desired. 

Charging devices is easy. Connect it to the LINDY power pack with a USB cable supplied to the device that requires more battery power and it will start to charge immediately.

The LINDY Power Pack provides instant access to extra battery life for iPhones, iPods, digital cameras, mobile phones, MP3 players and other mobile devices.The power pack itself can be recharged ready for its next use by connection to a computer’s USB port or by a 5V USB power supply using the supplied USB cable. Two LED lights show charge and charging statuses.

“Nothing is more frustrating than going to use a device to find it needs charging and having no access to a power socket or USB port,” says Andrew Ingram, product manager of LINDY Electronics.

“With its 2200mAH capacity, our new portable power pack has more than enough capacity to recharge the average mobile phone or digital camera.”
