Solar powered bicycle? Beware scam artists

A group of scam artists have launched a web site selling a solar powered bicycle. But the only thing it will end up powering is their bank account.

The name is a taken from a BC company that actually makes prefab eco-homes.

They have features like heavily insulated walls, wastewater-recovery systems and passive heating; one home has a wind turbine on the roof. Prefabrication minimizes waste
