The new range of SEE Toys from the Zen Design Group launching in the States right about now are green, environmentally friendly toys that never need batteries.

The feature a "power crank" that makes fun sounds to encourage kids to power them up by "kid-power".

The thinking behind the range is that kids have plenty of energy, so why not harness that rather than use non-renewable battery power.

Each SEE Toy comes with its own theme sound effects and super-bright, colour changing LEDs and has fun moving parts too.

The range comprises of the Dynafly, Dynacar, as well as a shark, a tiger and a dolphin too. They retail in the States from around $20.

A European launch is planned for the range soon.
