Gallery: Japan Announces World’s First Solar-Powered Public Bus


On September 1, the world’s first solar cell-equipped public bus will hit the streets of Okayama City in Southern Japan. The Sanyo-designed bus is a hybrid diesel-electric vehicle whose rooftop solar cells generate 798 watts, powering the interior LED lights. In the absence of sun, solar power stored in a battery will keep the lights on for nine hours.

The hybrid Toyota Prius offers a model with rooftop solar panels that run interior systems. The all-electric Blue Car does, too. But Sanyo’s Solarve bus is the first use of this technology in mass transit. Next stop: an all-solar vehicle in mass production?

    choco2000, what are you saying? That there’s more than enough oil and we don’t need to worry about alternative transportation?

    Please do balance those figures with reality: world oil consumption and delivery in this year, 2010, hovers around 87 million barrels PER DAY = 31755 million barrels PER YEAR. In other words, this seemingly enormous mount of new oil from Iran sounds stupendously big but would be gobbled up in a trice.

    When we start talking big numbers it is all too easy to lose track of relative amounts – the numbers are too big for our heads to appreciate.

    Iran has discovered 13 new oil and gas fields with in-place reserves of 14 billion barrels of oil and 45 trillion cubic feet of natural gas within the past 12 months.

    Shouldn’t the headline read, “Japan Announces World’s First Bus Lit Internally By Solar Power?”
    Perhaps if the passengers all wore head lamps the bus company would not need go to the expense of internal lighting and installing the solar panels but are they needed during the day anyway – install skylights?
    Okay, at night the lights could draw energy from batteries charged up by the panels, but then again, I’m back to my suggestion about the head lamps which could be given to all passengers at the start of the year. Having head lamps could also save on street lighting, lighting in shops and offices. Turning off the street lights etc could then reveal the beauty of the night sky.
    Its pretty neat being a hybrid diesel-electric bus: but its not solar powered! There’s no need to pad it out with false information.
