Sanyo sets up solar parking lots for bikes
The system uses lithium-ion batteries to charge 100 of Sanyo's "eneloop" bikes, with enough power left over to also illuminate the parking lot with LED lights at night.
The concept is a "completely independent and clean system eliminating the use of fossil fuels", said Sanyo Electric Co, which has emerged as a leader in solar and other alternative energy technologies.
The two lots, which also feature electric outlets to power external equipment in an emergency, were set up near commuter train lines in Tokyo's Setagaya ward, where the cycles will be parked for community use.
The charging points rely on rooftop photovoltaic panels, and Sanyo said the system also works on rainy days.
The eneloop "peddle-assist" bike features a "dynamotor" built into the hub of the front wheel, which charges a battery when the bicycle is cruising downhill or a rider is braking.
The bicycle's electric motor kicks in when a rider pedals, providing a virtual wind at one's back and making inclines feel more like flat terrain. There is a power boost mode for particularly steep climbs.
