Charge your phone while riding your bike - Siva Cycle

After the Urine Powered Generator, Solar Cooker, Solar hand-bag and the shoe charger, SolePower, this has to be my favourite gadget yet. It's very simple and practical. Might just start riding again :-D

I'm sure most of us have had our smartphones run out of battery at least once... Siva Cycle has created a gadget to stop that from happening again.

Best part is, Siva Cycle have pledged to donate one of the devices to those in need for every 10 purchases... cool!

Watch the video below to see how it works; pretty sweet.

Green Pavement makes Electricity

Paving slabs that convert energy from people's footsteps into electricity are set to help power Europe's largest urban mall, at the 2012 London Olympics site.

The recycled rubber "PaveGen" paving slabs harvest kinetic energy from the impact of people stepping on them and instantly deliver tiny bursts of electricity to nearby appliances. The slabs can also store energy for up to three days in an on-board battery, according to its creator.

The Potential

"Up to 52,000 people per hour pass through busy train stations. The average person takes around 200 million steps in their lifetime."
